The first city of the region was Durango, founded by Francisco de Ibarra, a Basque explorer. During the colonial era, Durango, Chihuahua and some parts of Sinaloa and Coahuila were a Basque colony named the Nueva Vizcaya. Now, most Duranguenses are Basque descendants. Other important cities like Monterrey were founded almost 50 years later.


California is a state in the Western United States. California borders Oregon to the north, Nevada and Arizona to the east, the Mexican state of Baja California to the south; and has a coastline along the Pacific Ocean to the west. With nearly 39.2 million residents across a total area of approximately 163,696 square miles (423,970 km²), it is the most populous and the third-largest U.S. state by area. It is also the most populated subnational entity in North America and the 34th most populous in the world. The Greater Los Angeles area and the San Francisco Bay Area are the nation's second and fifth most populous urban regions respectively, with the former having more than 18.7 million residents and the latter having over 9.6 million. Sacramento is the state's capital, while Los Angeles is the most populous city in the state and the second most populous city in the country (after New York City). Los Angeles County is the country's most populous, while San Bernardino County is the largest county by area in the country (Alaska has some larger subdivisions, but they are not called counties). San Francisco, which is both a city and a county, is the second most densely populated major city in the country (after New York City) and the fifth most densely populated county in the country, behind four of New York City's five boroughs.
The economy of California, with a gross state product of $3.2 trillion as of 2019, is the largest sub-national economy in the world. If it were a country, it would be the fifth-largest economy as of 2020 as well as the 37th most populous. The Greater Los Angeles area and the San Francisco Bay Area are the nation's second- and third-largest urban economies ($1.0 trillion and $0.5 trillion respectively as of 2020), after the New York metropolitan area ($1.8 trillion). The San Francisco Bay Area Combined Statistical Area had the nation's highest gross domestic product per capita ($106,757) among large primary statistical areas in 2018, and is home to five of the world's ten largest companies by market capitalization and four of the world's ten richest people.
Prior to European colonization, California was one of the most culturally and linguistically diverse areas in pre-Columbian North America and contained the highest Native American population density north of what is now Mexico. European exploration in the 16th and 17th centuries led to the colonization of California by the Spanish Empire. In 1804, it was included in Alta California province within the Viceroyalty of New Spain. The area became a part of Mexico in 1821, following its successful war for independence, but was ceded to the United States in 1848 after the Mexican–American War. The California Gold Rush started in 1848 and led to dramatic social and demographic changes, including large-scale immigration into California, a worldwide economic boom, and the California genocide of indigenous people. The western portion of Alta California was then organized and admitted as the 31st state on September 9, 1850, following the Compromise of 1850.
Notable contributions to popular culture, for example in entertainment and sports, have their origins in California. The state also has made noteworthy contributions in the fields of communication, information, innovation, environmentalism, economics, and politics. It is the home of Hollywood, the oldest and largest film industry in the world, which has had a profound effect on global entertainment. It is considered the origin of the hippie counterculture, beach and car culture, and the personal computer, among other innovations. The San Francisco Bay Area and the Greater Los Angeles Area are widely seen as the centers of the global technology and film industries, respectively. California's economy is very diverse: 58% of it is based on finance, government, real estate services, technology, and professional, scientific, and technical business services. Although it accounts for only 1.5% of the state's economy, California's agriculture industry has the highest output of any U.S. state. California's ports and harbors handle about a third of all U.S. imports, most originating in Pacific Rim international trade.
The state's extremely diverse geography ranges from the Pacific Coast and metropolitan areas in the west to the Sierra Nevada mountains in the east, and from the redwood and Douglas fir forests in the northwest to the Mojave Desert in the southeast. The Central Valley, a major agricultural area, dominates the state's center. Although California is well known for its warm Mediterranean climate and monsoon seasonal weather, the large size of the state results in climates that vary from moist temperate rainforest in the north to arid desert in the interior, as well as snowy alpine in the mountains. All these factors lead to an enormous demand for water. Over time, droughts and wildfires have been increasing in frequency and severity due to climate change and overextraction, becoming less seasonal and more year-round, further straining California's water security and having an impact on California business and industry in addition to agriculture.


In 1846, a group of American settlers in and around Sonoma rebelled against Mexican rule during the Bear Flag Revolt. Afterwards, rebels raised the Bear Flag (featuring a bear, a star, a red stripe and the words "California Republic") at Sonoma. The Republic's only president was William B. Ide, who played a pivotal role during the Bear Flag Revolt. This revolt by American settlers served as a prelude to the later American military invasion of California and was closely coordinated with nearby American military commanders.
The California Republic was short-lived; the same year marked the outbreak of the Mexican–American War (1846–48). When Commodore John D. Sloat of the United States Navy sailed into Monterey Bay and began the military occupation of California by the United States, Northern California capitulated in less than a month to the United States forces. After a series of defensive battles in Southern California, the Treaty of Cahuenga was signed by the Californios on January 13, 1847, securing American control in California.


The Spaniards gave the name Las Californias to the peninsula of Baja California and to Alta California, the region that became the present-day state of California.
The name likely derived from the mythical island of California in the fictional story of Queen Calafia, as recorded in a 1510 work The Adventures of Esplandián by Garci Rodríguez de Montalvo. This work was the fifth in a popular Spanish chivalric romance series that began with Amadís de Gaula. Queen Calafia's kingdom was said to be a remote land rich in gold and pearls, inhabited by beautiful Black women who wore gold armor and lived like Amazons, as well as griffins and other strange beasts. In the fictional paradise, the ruler Queen Calafia fought alongside Muslims and her name may have been chosen to echo the title of a Muslim leader, the Caliph. It is possible the name California was meant to imply the island was a Caliphate.
Know ye that at the right hand of the Indies there is an island called California, very close to that part of the Terrestrial Paradise, which was inhabited by black women without a single man among them, and they lived in the manner of Amazons. They were robust of body with strong passionate hearts and great virtue. The island itself is one of the wildest in the world on account of the bold and craggy rocks.
— Chapter CLVII of The Adventures of Esplandián
Shortened forms of the state's name include CA, Cal, Cali, Calif, Califas, and US-CA.


In 1821, the Mexican War of Independence gave the Mexican Empire (which included California) independence from Spain. For the next 25 years, Alta California remained a remote, sparsely populated, northwestern administrative district of the newly independent country of Mexico, which shortly after independence became a republic.
The missions, which controlled most of the best land in the state, were secularized by 1834 and became the property of the Mexican government. The governor granted many square leagues of land to others with political influence. These huge ranchos or cattle ranches emerged as the dominant institutions of Mexican California. The ranchos developed under ownership by Californios (Hispanics native of California) who traded cowhides and tallow with Boston merchants. Beef did not become a commodity until the 1849 California Gold Rush.
From the 1820s, trappers and settlers from the United States and the future Canada arrived in Northern California. These new arrivals used the Siskiyou Trail, California Trail, Oregon Trail and Old Spanish Trail to cross the rugged mountains and harsh deserts in and surrounding California.
The early government of the newly independent Mexico was highly unstable, and in a reflection of this, from 1831 onwards, California also experienced a series of armed disputes, both internal and with the central Mexican government. During this tumultuous political period Juan Bautista Alvarado was able to secure the governorship during 1836–1842. The military action which first brought Alvarado to power had momentarily declared California to be an independent state, and had been aided by Anglo-American residents of California, including Isaac Graham. In 1840, one hundred of those residents who did not have passports were arrested, leading to the Graham Affair, which was resolved in part with the intercession of Royal Navy officials.
One of the largest ranchers in California was John Marsh. After failing to obtain justice against squatters on his land from the Mexican courts, he determined that California should become part of the United States. Marsh conducted a letter-writing campaign espousing the California climate, the soil, and other reasons to settle there, as well as the best route to follow, which became known as "Marsh's route". His letters were read, reread, passed around, and printed in newspapers throughout the country, and started the first wagon trains rolling to California. He invited immigrants to stay on his ranch until they could get settled, and assisted in their obtaining passports.
After ushering in the period of organized emigration to California, Marsh became involved in a military battle between the much-hated Mexican general, Manuel Micheltorena and the California governor he had replaced, Juan Bautista Alvarado. The armies of each met at the Battle of Providencia near Los Angeles. Marsh had been forced against his will to join Micheltorena's army. Ignoring his superiors, during the battle, he signaled the other side for a parley. There were many settlers from the United States fighting on both sides. He convinced these men that they had no reason to be fighting each other. As a result of Marsh's actions, they abandoned the fight, Micheltorena was defeated, and California-born Pio Pico was returned to the governorship. This paved the way to California's ultimate acquisition by the United States.


Following the Treaty of Guadalupe Hidalgo (February 2, 1848) that ended the war, the westernmost portion of the annexed Mexican territory of Alta California soon became the American state of California, and the remainder of the old territory was then subdivided into the new American Territories of Arizona, Nevada, Colorado and Utah. The even more lightly populated and arid lower region of old Baja California remained as a part of Mexico. In 1846, the total settler population of the western part of the old Alta California had been estimated to be no more than 8,000, plus about 100,000 Native Americans, down from about 300,000 before Hispanic settlement in 1769.
In 1848, only one week before the official American annexation of the area, gold was discovered in California, this being an event which was to forever alter both the state's demographics and its finances. Soon afterward, a massive influx of immigration into the area resulted, as prospectors and miners arrived by the thousands. The population burgeoned with United States citizens, Europeans, Chinese and other immigrants during the great California Gold Rush. By the time of California's application for statehood in 1850, the settler population of California had multiplied to 100,000. By 1854, more than 300,000 settlers had come. Between 1847 and 1870, the population of San Francisco increased from 500 to 150,000. California was suddenly no longer a sparsely populated backwater, but seemingly overnight it had grown into a major population center.
The seat of government for California under Spanish and later Mexican rule had been located in Monterey from 1777 until 1845. Pio Pico, the last Mexican governor of Alta California, had briefly moved the capital to Los Angeles in 1845. The United States consulate had also been located in Monterey, under consul Thomas O. Larkin.
In 1849, a state Constitutional Convention was first held in Monterey. Among the first tasks of the convention was a decision on a location for the new state capital. The first full legislative sessions were held in San Jose (1850–1851). Subsequent locations included Vallejo (1852–1853), and nearby Benicia (1853–1854); these locations eventually proved to be inadequate as well. The capital has been located in Sacramento since 1854 with only a short break in 1862 when legislative sessions were held in San Francisco due to flooding in Sacramento.
Once the state's Constitutional Convention had finalized its state constitution, it applied to the U.S. Congress for admission to statehood. On September 9, 1850, as part of the Compromise of 1850, California became a free state and September 9 a state holiday.
During the American Civil War (1861–1865), California sent gold shipments eastwards to Washington in support of the Union. However, due to the existence of a large contingent of pro-South sympathizers within the state, the state was not able to muster any full military regiments to send eastwards to officially serve in the Union war effort. Still, several smaller military units within the Union army were unofficially associated with the state of California, such as the "California 100 Company", due to a majority of their members being from California.
At the time of California's admission into the Union, travel between California and the rest of the continental United States had been a time-consuming and dangerous feat. Nineteen years later, and seven years after it was greenlighted by President Lincoln, the First Transcontinental Railroad was completed in 1869. California was then reachable from the eastern States in a week's time.
Much of the state was extremely well suited to fruit cultivation and agriculture in general. Vast expanses of wheat, other cereal crops, vegetable crops, cotton, and nut and fruit trees were grown (including oranges in Southern California), and the foundation was laid for the state's prodigious agricultural production in the Central Valley and elsewhere.
In the nineteenth century, a large number of migrants from China traveled to the state as part of the Gold Rush or to seek work. Even though the Chinese proved indispensable in building the transcontinental railroad from California to Utah, perceived job competition with the Chinese led to anti-Chinese riots in the state, and eventually the US ended migration from China partially as a response to pressure from California with the 1882 Chinese Exclusion Act.


Under earlier Spanish and Mexican rule, California's original native population had precipitously declined, above all, from Eurasian diseases to which the indigenous people of California had not yet developed a natural immunity. Under its new American administration, California's harsh governmental policies towards its own indigenous people did not improve. As in other American states, many of the native inhabitants were soon forcibly removed from their lands by incoming American settlers such as miners, ranchers, and farmers. Although California had entered the American union as a free state, the "loitering or orphaned Indians" were de facto enslaved by their new Anglo-American masters under the 1853 Act for the Government and Protection of Indians. There were also massacres in which hundreds of indigenous people were killed.
Between 1850 and 1860, the California state government paid around 1.5 million dollars (some 250,000 of which was reimbursed by the federal government) to hire militias whose purpose was to protect settlers from the indigenous populations. In later decades, the native population was placed in reservations and rancherias, which were often small and isolated and without enough natural resources or funding from the government to sustain the populations living on them. As a result, the rise of California was a calamity for the native inhabitants. Several scholars and Native American activists, including Benjamin Madley and Ed Castillo, have described the actions of the California government as a genocide.


The first Europeans to explore the California coast were the members of a Spanish sailing expedition led by Portuguese captain Juan Rodríguez Cabrillo. Cabrillo was  commissioned by the Viceroy of New Spain in Mexico City to lead an expedition up the Pacific coast in search of trade opportunities; they entered San Diego Bay on September 28, 1542, and reached at least as far north as San Miguel Island. Privateer and explorer Francis Drake explored and claimed an undefined portion of the California coast in 1579, landing north of the future city of San Francisco. Sebastián Vizcaíno explored and mapped the coast of California in 1602 for New Spain, putting ashore in Monterey.
Despite the on-the-ground explorations of California in the 16th century, Rodríguez's idea of California as an island persisted. Such depictions appeared on many European maps well into the 18th century.
After the Portolà expedition of 1769–70, Spanish missionaries led by Junipero Serra began setting up 21 California Missions on or near the coast of Alta (Upper) California, beginning in San Diego. During the same period, Spanish military forces built several forts (presidios) and three small towns (pueblos). The San Francisco Mission grew into the city of San Francisco, and two of the pueblos grew into the cities of Los Angeles and San Jose. Several other smaller cities and towns also sprang up surrounding the various Spanish missions and pueblos, which remain to this day.
During this same period, sailors from the Russian Empire explored along the California coast and in 1812 established a trading post at Fort Ross. Russia's early 19th-century coastal settlements in California were positioned just north of the northernmost edge of the area of Spanish settlement in San Francisco Bay, and were the southernmost Russian settlements in North America. The Russian settlements associated with Fort Ross were spread from Point Arena to Tomales Bay.


Settled by successive waves of arrivals during at least the last 13,000 years, California was one of the most culturally and linguistically diverse areas in pre-Columbian North America. Various estimates of the native population have ranged from 100,000 to 300,000. The indigenous peoples of California included more than 70 distinct ethnic groups of Native Americans, ranging from large, settled populations living on the coast to groups in the interior. California groups also were diverse in their political organization with bands, tribes, villages, and on the resource-rich coasts, large chiefdoms, such as the Chumash, Pomo and Salinan. Trade, intermarriage and military alliances fostered many social and economic relationships among the diverse groups.


New Mexico has long been known for its dry, temperate climate. Overall the state is semi-arid to arid, with areas of continental and alpine climates at higher elevations. New Mexico's statewide average precipitation is 13.7 inches (350 mm) a year, with average monthly amounts peaking in the summer, particularly in the more rugged north-central area around Albuquerque and in the south. Generally, the eastern third of the state receives the most rainfall, while the western third receives the least. Higher altitudes receive around 40 inches (1,000 mm), while the lowest elevations see as little as 8 to 10 inches (200–250 mm).
Annual temperatures can range from 65 °F (18 °C) in the southeast to below 40 °F (4 °C) in the northern mountains, with the average being the mid-50s °F (12 °C). During the summer, daytime temperatures can often exceed 100 °F (38 °C) at elevations below 5,000 feet (1,500 m); the average high temperature in July ranges from 99 °F (37 °C) at the lower elevations down to 78 °F (26 °C) at the higher elevations. In the colder months of November to March, many cities in New Mexico can have nighttime temperature lows in the teens above zero, or lower. The highest temperature recorded in New Mexico was 122 °F (50 °C) at the Waste Isolation Pilot Plant (WIPP) near Loving on June 27, 1994; the lowest recorded temperature is −50 °F (−46 °C) at Gavilan (near Lindrith) on February 1, 1951.
New Mexico's stable climate and sparse population provides for clearer skies and less light pollution, making it a popular site for several major astronomical observatories, including the Apache Point Observatory, the Very Large Array, and the Magdalena Ridge Observatory, among others.


New Mexico (Spanish: Nuevo México [ˈnweβo ˈmexiko] (listen); Navajo: Yootó Hahoodzo [joː˩tʰo˥ ha˩hoː˩tso˩]) is a state in the Southwestern United States. It is one of the Mountain States of the southern Rocky Mountains, sharing the Four Corners region of the western U.S. with Utah, Colorado, and Arizona, and bordering Texas to the east and southeast, Oklahoma to the northeast, and the Mexican states of Chihuahua and Sonora to the south. The state capital is Santa Fe, which is the oldest capital in the U.S., founded in 1610 as the government seat of Nuevo México in New Spain; the largest city is Albuquerque. It was admitted as a state in 1912.
New Mexico is the fifth-largest of the fifty states, but with just over 2.1 million residents, ranks 36th in population and 46th in population density. Its climate and geography are highly varied, ranging from forested mountains to sparse deserts; the northern and eastern regions exhibit a colder alpine climate, while the west and south are warmer and more arid; the Rio Grande and its fertile valley runs from north-to-south, creating a riparian climate through the center of the state that supports a bosque habitat and distinct Albuquerque Basin climate. One–third of New Mexico's land is federally owned, and the state hosts many protected wilderness areas and national monuments, including three UNESCO World Heritage Sites, the most of any state.
New Mexico's economy and industries are some of the largest in the country, highlighted by the New Mexico Oil & Gas Association, EMNRD, New Mexico Technology Corridor, media in Albuquerque, and its film industry. And the state has is highly diversified sectors in cattle ranching, agriculture, lumber, scientific and technological research, tourism, and the arts, especially textiles and visual arts. Its total gross domestic product (GDP) in 2020 was $95.73 billion, with a GDP per capita of roughly $46,300. State tax policy is characterized by low to moderate taxation of resident personal income by national standards, with tax credits, exemptions, and special considerations for military personnel and favorable industries. Due to its large area and economic climate, New Mexico has a significant U.S. military presence, including White Sands Missile Range, and strategically valuable federal research centers, such as Sandia and Los Alamos National Laboratories. The state hosted several key facilities of the Manhattan Project, which developed the world's first atomic bomb, and was the site of the first nuclear test, Trinity.
In prehistoric times, New Mexico was home to Ancestral Puebloans, Mogollon, and the modern Comanche and Utes. Navajos and Apaches entered the state towards the end of the 15th century. Spanish explorers and settlers arrived in the 16th century, naming the territory Nuevo México after the Aztec Valley of Mexico, more than 250 years before the establishment and naming of the present-day country of Mexico; thus, the state did  not derive its name from Mexico. Isolated by its rugged terrain and the relative dominance of its indigenous people, New Mexico was a peripheral part of the viceroyalty of New Spain. Following Mexican independence in 1821, it became an autonomous region of Mexico, albeit increasingly threatened by the centralizing policies of the Mexican government, culminating in the Revolt of 1837; at the same time, the region became more economically dependent on the United States. At the conclusion of the Mexican–American War in 1848, the U.S. annexed New Mexico as part of the larger New Mexico Territory. It played a central role in U.S. westward expansion and was admitted to the Union as the 47th state on January 6, 1912.
New Mexico's history has contributed to its unique demographic and cultural character. One of only six majority-minority states, it has the nation's highest percentage of Hispanic and Latino Americans and the second-highest percentage of Native Americans after Alaska. New Mexico is home to part of the Navajo Nation, 19 federally recognized Pueblo communities, and three different federally recognized Apache tribes. Its large Hispanic population includes Hispanos, who descend from early Spanish settlers, as well as Chicanos and Mexicans. The New Mexican flag, which is among the most recognizable in the U.S., reflects the state's eclectic origins, bearing the scarlet and gold coloration of the Spanish flag along with the ancient sun symbol of the Zia, a Puebloan tribe. The confluence of indigenous, Spanish, Mexican, Hispanic, and American influences is also evident in New Mexico's unique cuisine, music genre, and architectural style.


The first known inhabitants of New Mexico were members of the Clovis culture of Paleo-Indians. Footprints discovered in 2017 suggest that humans may have been present in the region as long ago as 21,000–23,000 BC. Later inhabitants include American Indians of the Mogollon and Ancestral Pueblo cultures.


In January 2016, New Mexico sued the United States Environmental Protection Agency over negligence after the 2015 Gold King Mine waste water spill. The spill had caused heavy metals such as cadmium and lead and toxins such as arsenic to flow into the Animas River, polluting water basins of several states. The state has since implemented or considered stricter regulations and harsher penalties for spills associated with resource extraction.
New Mexico is a major producer of greenhouse gases. A study by Colorado State University showed that the state's oil and gas industry generated 60 million metric tons of greenhouse gases in 2018, over four times greater than previously estimated. The fossil fuels sector accounted for over half the state's overall emissions, which totaled 113.6 million metric tons, about 1.8% of the country's total and more than twice the national average per capita. The New Mexico government has responded with efforts to regulate industrial emissions, promote renewable energy, and incentivize the use of electric vehicles.


New Mexico received its name long before the present-day nation of Mexico won independence from Spain and adopted that name in 1821. The name "Mexico" derives from Nahuatl and originally referred to the heartland of the Mexica, the rulers of the Aztec Empire, in the Valley of Mexico.
Following their conquest of the Aztecs in the early 16th century, the Spanish began exploring what is now the western United States, using "Mexico" in 1563 to name the region of New Mexico (Spanish: Nuevo México). In 1581, the Chamuscado and Rodríguez Expedition named the region north of the Rio Grande San Felipe del Nuevo México. The Spaniards had hoped to find wealthy indigenous cultures similar to the Mexica. The indigenous cultures of New Mexico, however, proved to be unrelated to the Mexica and lacking in riches, but the name persisted.
Before statehood in 1912, the name "New Mexico" loosely applied to various configurations of territories in the same general area, which evolved throughout the Spanish, Mexican, and U.S. periods, but typically encompassed most of present-day New Mexico along with sections of neighboring states.


With a total area of 121,590 square miles (314,900 km²), New Mexico is the fifth-largest state, after Alaska, Texas, California, and Montana. Its eastern border lies along 103°W longitude with the state of Oklahoma, and 2.2 miles (3.5 kilometres) west of 103°W longitude with Texas (due to a 19th-century surveying error). On the southern border, Texas makes up the eastern two-thirds, while the Mexican states of Chihuahua and Sonora make up the western third, with Chihuahua making up about 90% of that. The western border with Arizona runs along the 109° 03'W longitude. The southwestern corner of the state is known as the Bootheel. The 37°N parallel forms the northern boundary with Colorado. The states of New Mexico, Colorado, Arizona, and Utah come together at the Four Corners in New Mexico's northwestern corner. Its surface water area is about 292 square miles (760 km²).
Despite its popular depiction as mostly arid desert, New Mexico has one of the most diverse landscapes of any U.S. state, ranging from wide, auburn-colored deserts and verdant grasslands, to broken mesas and high, snow-capped peaks. Close to a third of the state is covered in timberland, with heavily forested mountain wildernesses dominating the north. The Sangre de Cristo Mountains, the southernmost part of the Rocky Mountains, run roughly north–south along the east side of the Rio Grande, in the rugged, pastoral north. The Great Plains extend into the eastern third of the state, most notably the Llano Estacado ("Staked Plain"), whose westernmost boundary is marked by the Mescalero Ridge escarpment. The northwestern quadrant of New Mexico is dominated by the Colorado Plateau, characterized by unique volcanic formations, dry grasslands and shrublands, open pinyon-juniper woodland, and mountain forests. The Chihuahuan Desert, which is the largest in North America, extends through the south.
Over four–fifths of New Mexico is higher than 4,000 feet (1,250 meters) above sea level. The average elevation ranges from up to 8,000 feet (2,500 meters) above sea level in the northwest, to less than 4,000 feet in the southeast. The highest point is Wheeler Peak at over 13,160 feet (4,011 meters) in the Sangre de Cristo Mountains, while the lowest is the Red Bluff Reservoir at around 2,840 feet (866 meters), in the southeastern corner of the state.
In addition to the Rio Grande, which is tied for the fourth-longest river in the U.S., New Mexico has four other major river systems: the Pecos, Canadian, San Juan, and Gila. Nearly bisecting New Mexico from north to south, the Rio Grande has played an influential role in the region's history; its fertile floodplain has supported human habitation since prehistoric times, and European settlers initially lived exclusively in its valleys and along its tributaries. The Pecos, which flows roughly parallel to the Rio Grande at its east, was a popular route for explorers, as was the Canadian River, which rises in the mountainous north and flows east across the arid plains. The San Juan and Gila lie west of the Continental Divide, in the northwest and southwest, respectively. With the exception of the Gila, all major rivers are dammed in New Mexico and provide a major water source for irrigation and flood control.
Aside from its rivers, New Mexico has few sizeable natural bodies of water; there are several artificial lakes and reservoirs, the largest being Elephant Butte Reservoir, which was created by the damming of the Rio Grande. At its height in the early 20th century, the reservoir was the largest man-made lake in the world.


Owing to its varied topography, New Mexico has six distinct vegetation zones that provide diverse sets of habitats for many plants and animals. The Upper Sonoran Zone is by far the most prominent, constituting about three-fourths of the state; it includes most of the plains, foothills, and valleys above 4,500 feet, and is defined by prairie grasses, low piñon pines, and juniper shrubs. The Llano Estacado in the east features shortgrass prairie with blue grama, which sustain bison. The Chihuahuan Desert in the south is characterized by shrubby creosote. The Colorado Plateau in the northwest corner of New Mexico is high desert with cold winters, featuring sagebrush, shadescale, greasewood, and other plants adapted to the saline and seleniferous soil.
The mountainous north hosts a wide array of vegetation types corresponding to elevation gradients, such as piñon-juniper woodlands near the base, through evergreen conifers, spruce-fir and aspen forests in the transitionary zone, and Krummholz, and alpine tundra at the very top. The Apachian zone tucked into the southwestern bootheel of the state has high-calcium soil, oak woodlands, Arizona cypress, and other plants that are not found in other parts of the state. The southern sections of the Rio Grande and Pecos valleys have 20,000 square miles (52,000 square km) of New Mexico's best grazing land and irrigated farmland.
New Mexico's varied climate and vegetation zones consequently support diverse wildlife. Black bears, bighorn sheep, bobcats, cougars, deer, and elk live in habitats above 7,000 feet, while coyotes, jackrabbits, kangaroo rats, javelina, porcupines, pronghorn antelope, western diamondbacks, and wild turkeys live in less mountainous and elevated regions. The iconic roadrunner, which is the state bird, is abundant in the southeast. Endangered species include the Mexican gray wolf, which is being gradually reintroduced in the world, and Rio Grande silvery minnow. Over 500 species of birds live or migrate through New Mexico, third only to California and Mexico.


Thousands of years before the arrival of European explorers, the Ancestral Puebloans and the Fremont people lived in what is now known as Utah, some of which spoke languages of the Uto-Aztecan group. Ancestral Pueblo peoples built their homes through excavations in mountains, and the Fremont people built houses of straw before disappearing from the region around the 15th century.
Another group of Native Americans, the Navajo, settled in the region around the 18th century. In the mid-18th century, other Uto-Aztecan tribes, including the Goshute, the Paiute, the Shoshone, and the Ute people, also settled in the region. These five groups were present when the first European explorers arrived.


The southern Utah region was explored by the Spanish in 1540, led by Francisco Vázquez de Coronado, while looking for the legendary Cíbola. A group led by two Catholic priests—sometimes called the Domínguez–Escalante expedition—left Santa Fe in 1776, hoping to find a route to the coast of California. The expedition traveled as far north as Utah Lake and encountered the native residents. The Spanish made further explorations in the region but were not interested in colonizing the area because of its desert nature. In 1821, the year Mexico achieved its independence from Spain, the region became known as part of its territory of Alta California.
European trappers and fur traders explored some areas of Utah in the early 19th century from Canada and the United States. The city of Provo, Utah, was named for one Étienne Provost, who visited the area in 1825. The city of Ogden, Utah, was named after Peter Skene Ogden, a Canadian explorer who traded furs in the Weber Valley.
In late 1824, Jim Bridger became the first known English-speaking person to sight the Great Salt Lake. Due to the high salinity of its waters, he thought he had found the Pacific Ocean; he subsequently learned this body of water was a giant salt lake. After the discovery of the lake, hundreds of American and Canadian traders and trappers established trading posts in the region. In the 1830s, thousands of migrants traveling from the Eastern United States to the American West began to make stops in the region of the Great Salt Lake, then known as Lake Youta.


Beginning in the early 20th century, with the establishment of such national parks as Bryce Canyon National Park and Zion National Park, Utah became known for its natural beauty. Southern Utah became a popular filming spot for arid, rugged scenes featured in the popular mid-century western film genre. From such films, most US residents recognize such natural landmarks as Delicate Arch and "the Mittens" of Monument Valley. During the 1950s, 1960s, and 1970s, with the construction of the Interstate highway system, accessibility to the southern scenic areas was made easier.
Since the establishment of Alta Ski Area in 1939 and the subsequent development of several ski resorts in the state's mountains, Utah's skiing has become world-renowned. The dry, powdery snow of the Wasatch Range is considered some of the best skiing in the world (the state license plate once claimed "the Greatest Snow on Earth"). Salt Lake City won the bid for the 2002 Winter Olympic Games, and this served as a great boost to the economy. The ski resorts have increased in popularity, and many of the Olympic venues built along the Wasatch Front continue to be used for sporting events. Preparation for the Olympics spurred the development of the light-rail system in the Salt Lake Valley, known as TRAX, and the re-construction of the freeway system around the city.
In 1957, Utah created the Utah State Parks Commission with four parks. Today, Utah State Parks manages 43 parks and several undeveloped areas totaling over 95,000 acres (380 km²) of land and more than 1,000,000 acres (4,000 km²) of water. Utah's state parks are scattered throughout Utah, from Bear Lake State Park at the Utah/Idaho border to Edge of the Cedars State Park Museum deep in the Four Corners region and everywhere in between. Utah State Parks is also home to the state's off highway vehicle office, state boating office and the trails program.
During the late 20th century, the state grew quickly. In the 1970s growth was phenomenal in the suburbs of the Wasatch Front. Sandy was one of the fastest-growing cities in the country at that time. Today, many areas of Utah continue to see boom-time growth. Northern Davis, southern and western Salt Lake, Summit, eastern Tooele, Utah, Wasatch, and Washington counties are all growing very quickly. Management of transportation and urbanization are major issues in politics, as development consumes agricultural land and wilderness areas and transportation is a major reason for poor air quality in Utah.


The Utah Territory was much smaller than the proposed state of Deseret, but it still contained all of the present states of Nevada and Utah as well as pieces of modern Wyoming and Colorado. It was created with the Compromise of 1850, and Fillmore, named after President Millard Fillmore, was designated the capital. The territory was given the name Utah after the Ute tribe of Native Americans. Salt Lake City replaced Fillmore as the territorial capital in 1856.
By 1850, there were around 100 black people in the territory, the majority of whom were slaves. In Salt Lake County, 26 slaves were counted. In 1852, the territorial legislature passed the Act in Relation to Service and the Act for the relief of Indian Slaves and Prisoners formally legalizing slavery in the territory. Slavery was abolished in the territory during the Civil War.
In 1850, Salt Lake City sent out a force known as the Nauvoo Legion and engaged the Timpanogos in the Battle at Fort Utah.
Disputes between the Mormon inhabitants and the U.S. government intensified due to the practice of plural marriage, or polygamy, among members of the LDS Church. The Mormons were still pushing for the establishment of a State of Deseret with the new borders of the Utah Territory. Most, if not all, of the members of the U.S. government opposed the polygamous practices of the Mormons.
Members of the LDS Church were viewed as un-American and rebellious when news of their polygamous practices spread. In 1857, particularly heinous accusations of abdication of government and general immorality were leveled by former associate justice William W. Drummond, among others. The detailed reports of life in Utah caused the administration of James Buchanan to send a secret military "expedition" to Utah. When the supposed rebellion should be quelled, Alfred Cumming would take the place of Brigham Young as territorial governor. The resulting conflict is known as the Utah War, nicknamed "Buchanan's Blunder" by the Mormon leaders.
In September 1857, about 120 American settlers of the Baker–Fancher wagon train, en route to California from Arkansas, were murdered by Utah Territorial Militia and some Paiute Native Americans in the Mountain Meadows massacre.
Before troops led by Albert Sidney Johnston entered the territory, Brigham Young ordered all residents of Salt Lake City to evacuate southward to Utah Valley and sent out the Nauvoo Legion to delay the government's advance. Although wagons and supplies were burned, eventually the troops arrived in 1858, and Young surrendered official control to Cumming, although most subsequent commentators claim that Young retained true power in the territory. A steady stream of governors appointed by the president quit the position, often citing the traditions of their supposed territorial government. By agreement with Young, Johnston established Camp Floyd, 40 miles (60 km) away from Salt Lake City, to the southwest.
Salt Lake City was the last link of the First Transcontinental Telegraph, completed in October 1861. Brigham Young was among the first to send a message, along with Abraham Lincoln and other officials.
Because of the American Civil War, federal troops were pulled out of Utah Territory in 1861. This was a boon to the local economy as the army sold everything in camp for pennies on the dollar before marching back east to join the war. The territory was then left in LDS hands until Patrick E. Connor arrived with a regiment of California volunteers in 1862. Connor established Fort Douglas just 3 miles (4.8 km) east of Salt Lake City and encouraged his people to discover mineral deposits to bring more non-Mormons into the territory. Minerals were discovered in Tooele County and miners began to flock to the territory.
Beginning in 1865, Utah's Black Hawk War developed into the deadliest conflict in the territory's history. Chief Antonga Black Hawk died in 1870, but fights continued to break out until additional federal troops were sent in to suppress the Ghost Dance of 1872. The war is unique among Indian Wars because it was a three-way conflict, with mounted Timpanogos Utes led by Antonga Black Hawk fighting federal and LDS authorities.
On May 10, 1869, the First Transcontinental Railroad was completed at Promontory Summit, north of the Great Salt Lake. The railroad brought increasing numbers of people into the territory and several influential businesspeople made fortunes there.
During the 1870s and 1880s laws were passed to punish polygamists due, in part, to stories from Utah. Notably, Ann Eliza Young—tenth wife to divorce Brigham Young, women's advocate, national lecturer and author of Wife No. 19 or My Life of Bondage and Mr. and Mrs. Fanny Stenhouse, authors of The Rocky Mountain Saints (T. B. H. Stenhouse, 1873) and Tell It All: My Life in Mormonism (Fanny Stenhouse, 1875). Both Ann Eliza and Fanny testify to the happiness of the very early Church members before polygamy. They independently published their books in 1875. These books and the lectures of Ann Eliza Young have been credited with the United States Congress passage of anti-polygamy laws by newspapers throughout the United States as recorded in "The Ann Eliza Young Vindicator", a pamphlet which detailed Ms Young's travels and warm reception throughout her lecture tour.
T. B. H. Stenhouse, former Utah Mormon polygamist, Mormon missionary for thirteen years and a Salt Lake City newspaper owner, finally left Utah and wrote The Rocky Mountain Saints. His book gives a witnessed account of life in Utah, both the good and the bad. He finally left Utah and Mormonism after financial ruin occurred when Brigham Young sent Stenhouse to relocate to Ogden, Utah, according to Stenhouse, to take over his thriving pro-Mormon Salt Lake Telegraph newspaper. In addition to these testimonies, The Confessions of John D. Lee, written by John D. Lee—alleged "Scape goat" for the Mountain Meadow Massacre—also came out in 1877. The corroborative testimonies coming out of Utah from Mormons and former Mormons influenced Congress and the people of the United States.
In the 1890 Manifesto, the LDS Church banned polygamy. When Utah applied for statehood again, it was accepted. One of the conditions for granting Utah statehood was that a ban on polygamy be written into the state constitution. This was a condition required of other western states that were admitted into the Union later. Statehood was officially granted on January 4, 1896.


Utah (/ˈjuːtɑː/ YOO-tah, /ˈjuːtɔː/ (listen) YOO-taw) is a state in the Mountain West subregion of the Western United States. Utah is a landlocked U.S. state bordered to its east by Colorado, to its northeast by Wyoming, to its north by Idaho, to its south by Arizona, and to its west by Nevada. Utah also touches a corner of New Mexico in the southeast. Of the fifty U.S. states, Utah is the 13th-largest by area; with a population over three million, it is the 30th-most-populous and 11th-least-densely populated. Urban development is mostly concentrated in two areas: the Wasatch Front in the north-central part of the state, which is home to roughly two-thirds of the population and includes the capital city, Salt Lake City; and Washington County in the southwest, with more than 180,000 residents. Most of the western half of Utah lies in the Great Basin.
Utah has been inhabited for thousands of years by various indigenous groups such as the ancient Puebloans, Navajo and Ute. The Spanish were the first Europeans to arrive in the mid-16th century, though the region's difficult geography and harsh climate made it a peripheral part of New Spain and later Mexico. Even while it was Mexican territory, many of Utah's earliest settlers were American, particularly Mormons fleeing marginalization and persecution from the United States. Following the Mexican–American War in 1848, the region was annexed by the U.S., becoming part of the Utah Territory, which included what is now Colorado and Nevada. Disputes between the dominant Mormon community and the federal government delayed Utah's admission as a state; only after the outlawing of polygamy was it admitted in 1896 as the 45th.
People from Utah are known as Utahns. Slightly over half of all Utahns are Mormons, the vast majority of whom are members of The Church of Jesus Christ of Latter-day Saints (LDS Church), which has its world headquarters in Salt Lake City; Utah is the only state where a majority of the population belongs to a single church. The LDS Church greatly influences Utahn culture, politics, and daily life, though since the 1990s the state has become more religiously diverse as well as secular.
Utah has a highly diversified economy, with major sectors including transportation, education, information technology and research, government services, mining, and tourism. Utah has been one of the fastest growing states since 2000, with the 2020 U.S. Census confirming the fastest population growth in the nation since 2010. St. George was the fastest-growing metropolitan area in the United States from 2000 to 2005. Utah ranks among the overall best states in metrics such as healthcare, governance, education, and infrastructure. It has the 14th-highest median average income and the least income inequality of any U.S. state. Over time and influenced by climate change, droughts in Utah have been increasing in frequency and severity, putting a further strain on Utah's water security and impacting the state’s economy.


Following the death of Joseph Smith in 1844, Brigham Young, as president of the Quorum of the Twelve, became the leader of the LDS Church in Nauvoo, Illinois. To address the growing conflicts between his people and their neighbors, Young agreed with Illinois Governor Thomas Ford in October 1845 that the Mormons would leave by the following year.
Young and the first group of Mormon pioneers reached the Salt Lake Valley on July 24, 1847. Over the next 22 years, more than 70,000 pioneers crossed the plains and settled in Utah. For the first few years, Brigham Young and the thousands of early settlers of Salt Lake City struggled to survive. The arid desert land was deemed by the Mormons as desirable as a place where they could practice their religion without harassment.
Settlers buried thirty-six Native Americans in one grave after an outbreak of measles occurred during the winter of 1847.
The first group of settlers brought African slaves with them, making Utah the only place in the western United States to have African slavery. Three slaves, Green Flake, Hark Lay, and Oscar Crosby, came west with the first group of settlers in 1847. The settlers also began to purchase Indian slaves in the well-established Indian slave trade, as well as enslaving Indian prisoners of war.
Utah was Mexican territory when the first pioneers arrived in 1847. Early in the Mexican–American War in late 1846, the United States had taken control of New Mexico and California. The entire Southwest became U.S. territory upon the signing of the Treaty of Guadalupe Hidalgo, February 2, 1848. The treaty was ratified by the United States Senate on March 11. Learning that California and New Mexico were applying for statehood, the settlers of the Utah area (originally having planned to petition for territorial status) applied for statehood with an ambitious plan for a State of Deseret.
The Mormon settlements provided pioneers for other settlements in the West. Salt Lake City became the hub of a "far-flung commonwealth" of Mormon settlements. With new church converts coming from the East and around the world, Church leaders often assigned groups of church members as missionaries to establish other settlements throughout the West. They developed irrigation to support fairly large pioneer populations along Utah's Wasatch front (Salt Lake City, Bountiful and Weber Valley, and Provo and Utah Valley). Throughout the remainder of the 19th century, Mormon pioneers established hundreds of other settlements in Utah, Idaho, Nevada, Arizona, Wyoming, California, Canada, and Mexico—including in Las Vegas, Nevada; Franklin, Idaho (the first European settlement in Idaho); San Bernardino, California; Mesa, Arizona; Star Valley, Wyoming; and Carson Valley, Nevada.
Prominent settlements in Utah included St. George, Logan, and Manti (where settlers completed the LDS Church's first three temples in Utah, each started after but finished many years before the larger and better known temple built in Salt Lake City was completed in 1893), as well as Parowan, Cedar City, Bluff, Moab, Vernal, Fillmore (which served as the territorial capital between 1850 and 1856), Nephi, Levan, Spanish Fork, Springville, Provo Bench (now Orem), Pleasant Grove, American Fork, Lehi, Sandy, Murray, Jordan, Centerville, Farmington, Huntsville, Kaysville, Grantsville, Tooele, Roy, Brigham City, and many other smaller towns and settlements. Young had an expansionist's view of the territory that he and the Mormon pioneers were settling, calling it Deseret—which according to the Book of Mormon was an ancient word for "honeybee". This is symbolized by the beehive on the Utah flag, and the state's motto, "Industry".


The name Utah is said to derive from the name of the Ute tribe, meaning 'people of the mountains'. However, no such word actually exists in the Utes' language, and the Utes refer to themselves as Noochee. The meaning of Utes as 'the mountain people' has been attributed to the neighboring Pueblo Indians, as well as to the Apache word Yuttahih, which means 'one that is higher up' or 'those that are higher up'. In Spanish it was pronounced Yuta; subsequently English-speaking people may have adapted the word as Utah.


Utah is known for its natural diversity and is home to features ranging from arid deserts with sand dunes to thriving pine forests in mountain valleys. It is a rugged and geographically diverse state at the convergence of three distinct geological regions: the Rocky Mountains, the Great Basin, and the Colorado Plateau.
Utah covers an area of 84,899 sq mi (219,890 km²). It is one of the Four Corners states and is bordered by Idaho in the north, Wyoming in the north and east, by Colorado in the east, at a single point by New Mexico to the southeast, by Arizona in the south, and by Nevada in the west. Only three U.S. states (Utah, Colorado, and Wyoming) have exclusively latitude and longitude lines as boundaries.
One of Utah's defining characteristics is the variety of its terrain. Running down the middle of the state's northern third is the Wasatch Range, which rises to heights of almost 12,000 ft (3,700 m) above sea level. Utah is home to world-renowned ski resorts made popular by light, fluffy snow and winter storms that regularly dump up to three feet of it overnight. In the state's northeastern section, running east to west, are the Uinta Mountains, which rise to heights of over 13,000 feet (4,000 m). The highest point in the state, Kings Peak, at 13,528 feet (4,123 m), lies within the Uinta Mountains.
At the western base of the Wasatch Range is the Wasatch Front, a series of valleys and basins that are home to the most populous parts of the state. It stretches approximately from Brigham City at the north end to Nephi at the south end. Approximately 75 percent of the state's population lives in this corridor, and population growth is rapid.
Western Utah is mostly arid desert with a basin and range topography. Small mountain ranges and rugged terrain punctuate the landscape. The Bonneville Salt Flats are an exception, being comparatively flat as a result of once forming the bed of ancient Lake Bonneville. Great Salt Lake, Utah Lake, Sevier Lake, and Rush Lake are all remnants of this ancient freshwater lake, which once covered most of the eastern Great Basin. West of the Great Salt Lake, stretching to the Nevada border, lies the arid Great Salt Lake Desert. One exception to this aridity is Snake Valley, which is (relatively) lush due to large springs and wetlands fed from groundwater derived from snow melt in the Snake Range, Deep Creek Range, and other tall mountains to the west of Snake Valley. Great Basin National Park is just over the Nevada state line in the southern Snake Range. One of western Utah's most impressive, but least visited attractions is Notch Peak, the tallest limestone cliff in North America, located west of Delta.
Much of the scenic southern and southeastern landscape (specifically the Colorado Plateau region) is sandstone, specifically Kayenta sandstone and Navajo sandstone. The Colorado River and its tributaries wind their way through the sandstone, creating some of the world's most striking and wild terrain (the area around the confluence of the Colorado and Green Rivers was the last to be mapped in the lower 48 United States). Wind and rain have also sculpted the soft sandstone over millions of years. Canyons, gullies, arches, pinnacles, buttes, bluffs, and mesas are the common sights throughout south-central and southeast Utah.
This terrain is the central feature of protected state and federal parks such as Arches, Bryce Canyon, Canyonlands, Capitol Reef, and Zion national parks, Cedar Breaks, Grand Staircase-Escalante, Hovenweep, and Natural Bridges national monuments, Glen Canyon National Recreation Area (site of the popular tourist destination, Lake Powell), Dead Horse Point and Goblin Valley state parks, and Monument Valley. The Navajo Nation also extends into southeastern Utah. Southeastern Utah is also punctuated by the remote, but lofty La Sal, Abajo, and Henry mountain ranges.
Eastern (northern quarter) Utah is a high-elevation area covered mostly by plateaus and basins, particularly the Tavaputs Plateau and San Rafael Swell, which remain mostly inaccessible, and the Uinta Basin, where the majority of eastern Utah's population lives. Economies are dominated by mining, oil shale, oil, and natural gas-drilling, ranching, and recreation. Much of eastern Utah is part of the Uintah and Ouray Indian Reservation. The most popular destination within northeastern Utah is Dinosaur National Monument near Vernal.
Southwestern Utah is the lowest and hottest spot in Utah. It is known as Utah's Dixie because early settlers were able to grow some cotton there. Beaverdam Wash in far southwestern Utah is the lowest point in the state, at 2,000 feet (610 m). The northernmost portion of the Mojave Desert is also located in this area. Dixie is quickly becoming a popular recreational and retirement destination, and the population is growing rapidly. Although the Wasatch Mountains end at Mount Nebo near Nephi, a complex series of mountain ranges extends south from the southern end of the range down the spine of Utah. Just north of Dixie and east of Cedar City is the state's highest ski resort, Brian Head.
Like most of the western and southwestern states, the federal government owns much of the land in Utah. Over 70 percent of the land is either BLM land, Utah State Trustland, or U.S. National Forest, U.S. National Park, U.S. National Monument, National Recreation Area or U.S. Wilderness Area. Utah is the only state where every county contains some national forest.


Laurentia is an ancient craton which forms the geologic core of North America; it formed between 1.5 and 1.0 billion years ago during the Proterozoic eon. The Canadian Shield is the largest exposure of this craton. From the Late Paleozoic to Early Mesozoic eras, North America was joined with the other modern-day continents as part of the supercontinent Pangaea, with Eurasia to its east. One of the results of the formation of Pangaea was the Appalachian Mountains, which formed some 480 million years ago, making it among the oldest mountain ranges in the world. When Pangaea began to rift around 200 million years ago, North America became part of Laurasia, before it separated from Eurasia as its own continent during the mid-Cretaceous period. The Rockies and other western mountain ranges began forming around this time from a period of mountain building called the Laramide orogeny, between 80 and 55 million years ago. The formation of the Isthmus of Panama that connected the continent to South America arguably occurred approximately 12 to 15 million years ago, and the Great Lakes (as well as many other northern freshwater lakes and rivers) were carved by receding glaciers about 10,000 years ago.
North America is the source of much of what humanity knows about geologic time periods. The geographic area that would later become the United States has been the source of more varieties of dinosaurs than any other modern country. According to paleontologist Peter Dodson, this is primarily due to stratigraphy, climate and geography, human resources, and history. Much of the Mesozoic Era is represented by exposed outcrops in the many arid regions of the continent. The most significant Late Jurassic dinosaur-bearing fossil deposit in North America is the Morrison Formation of the western United States.


The United Nations formally recognizes "North America" as comprising three areas: Northern America, Central America, and the Caribbean. This has been formally defined by the UN Statistics Division.
"Northern America", as a term distinct from "North America", excludes Central America, which itself may or may not include Mexico (see Central America § Different definitions). In the limited context of the North American Free Trade Agreement, the term covers Canada, the United States, and Mexico, which are the three signatories of that treaty.
France, Italy, Portugal, Spain, Romania, Greece, and the countries of Latin America use a six-continent model, with the Americas viewed as a single continent and North America designating a subcontinent comprising Canada, the United States, Mexico, and Saint Pierre et Miquelon (politically part of France), and often Greenland, and Bermuda.
North America has been historically referred to by other names. Spanish North America (New Spain) was often referred to as Northern America, and this was the first official name given to Mexico.


Central America is geologically active with volcanic eruptions and earthquakes occurring from time to time. In 1976 Guatemala was hit by a major earthquake, killing 23,000 people; Managua, the capital of Nicaragua, was devastated by earthquakes in 1931 and 1972, the last one killing about 5,000 people; three earthquakes devastated El Salvador, one in 1986 and two in 2001; one earthquake devastated northern and central Costa Rica in 2009, killing at least 34 people; in Honduras a powerful earthquake killed seven people in 2009.
Volcanic eruptions are common in the region. In 1968 the Arenal Volcano, in Costa Rica, erupted and killed 87 people. Fertile soils from weathered volcanic lavas have made it possible to sustain dense populations in agriculturally productive highland areas.
Central America has many mountain ranges; the longest are the Sierra Madre de Chiapas, the Cordillera Isabelia, and the Cordillera de Talamanca. Between the mountain ranges lie fertile valleys that are suitable for the people; in fact, most of the population of Honduras, Costa Rica, and Guatemala live in valleys. Valleys are also suitable for the production of coffee, beans, and other crops.


The Americas are usually accepted as having been named after the Italian explorer Amerigo Vespucci by the German cartographers Martin Waldseemüller and Matthias Ringmann. Vespucci, who explored South America between 1497 and 1502, was the first European to suggest that the Americas were not the East Indies, but a different landmass previously unknown by Europeans. In 1507, Waldseemüller produced a world map, in which he placed the word "America" on the continent of South America, in the middle of what is today Brazil. He explained the rationale for the name in the accompanying book Cosmographiae Introductio: "ab Americo inventore ... quasi Americi terram sive Americam (from Americus the discoverer ... as if it were the land of Americus, thus America)". What was known about North American continent was referred to as Parias above what is today Mexico. A 1553 world map published by Petrus Apianus in his Charta Cosmographica, Cum Ventorum Propria Natura et Operatione, North America was called Baccalearum, meaning "realm of the Cod fish", in reference to the abundance of Cod fish on the east coast.
For Waldseemüller, no one should object to the naming of the land after its discoverer. He used the Latinized version of Vespucci's name (Americus Vespucius), but in its feminine form "America", following the examples of "Europa", "Asia" and "Africa". Later, other mapmakers extended the name America to the northern continent, dropping the usage of "Parias". In 1538, Gerard Mercator used America on his map of the world for all the Western Hemisphere.
Some argue that because the convention is to use the surname for naming discoveries (except in the case of royalty), the derivation from "Amerigo Vespucci" could be put in question. In 1874, Thomas Belt published the indigenous name of the Amerrisque Mountains of Central America; the next year, Jules Marcou suggested that the name of the continent stemmed from that of the mountain range. Marcou corresponded with Augustus Le Plongeon, who wrote: "The name AMERICA or AMERRIQUE in the Mayan language means, a country of perpetually strong wind, or the Land of the Wind, and ... the [suffixes] can mean ... a spirit that breathes, life itself."
Mercator on his map called North America "America or New India" (America sive India Nova). The Spanish Empire called its territories in North and South America "Las Indias"; the state body overseeing them was the Council of the Indies.


North America occupies the northern portion of the landmass generally referred to as the New World, the Western Hemisphere, the Americas, or simply America (which, in many countries is considered as a single continent with North America a subcontinent). North America is the third-largest continent by area, following Asia and Africa. North America's only land connection to South America is at the Isthmus of Darian/Isthmus of Panama. The continent is delimited on the southeast by most geographers at the Darién watershed along the Colombia-Panama border, placing almost all of Panama within North America. Alternatively, some geologists physiographically locate its southern limit at the Isthmus of Tehuantepec, Mexico, with Central America extending southeastward to South America from this point. The Caribbean islands, or West Indies, are considered part of North America. The continental coastline is long and irregular. The Gulf of Mexico is the largest body of water indenting the continent, followed by Hudson Bay. Others include the Gulf of Saint Lawrence and the Gulf of California.
Before the Central American isthmus formed, the region had been underwater. The islands of the West Indies delineate a submerged former land bridge, which had connected North and South America via what are now Florida and Venezuela.
There are numerous islands off the continent's coasts; principally, the Arctic Archipelago, the Bahamas, Turks & Caicos, the Greater and Lesser Antilles, the Aleutian Islands (some of which are in the Eastern Hemisphere proper), the Alexander Archipelago, the many thousand islands of the British Columbia Coast, and Newfoundland. Greenland, a self-governing Danish island, and the world's largest, is on the same tectonic plate (the North American Plate) and is part of North America geographically. In a geologic sense, Bermuda is not part of the Americas, but an oceanic island that was formed on the fissure of the Mid-Atlantic Ridge over 100 million years ago. The nearest landmass to it is Cape Hatteras, North Carolina. However, Bermuda is often thought of as part of North America, especially given its historical, political and cultural ties to Virginia and other parts of the continent.
The vast majority of North America is on the North American Plate. Parts of western Mexico, including Baja California, and of California, including the cities of San Diego, Los Angeles, and Santa Cruz, lie on the eastern edge of the Pacific Plate, with the two plates meeting along the San Andreas fault. The southernmost portion of the continent and much of the West Indies lie on the Caribbean Plate, whereas the Juan de Fuca and Cocos plates border the North American Plate on its western frontier.
The continent can be divided into four great regions (each of which contains many subregions): the Great Plains stretching from the Gulf of Mexico to the Canadian Arctic; the geologically young, mountainous west, including the Rocky Mountains, the Great Basin, California and Alaska; the raised but relatively flat plateau of the Canadian Shield in the northeast; and the varied eastern region, which includes the Appalachian Mountains, the coastal plain along the Atlantic seaboard, and the Florida peninsula. Mexico, with its long plateaus and cordilleras, falls largely in the western region, although the eastern coastal plain does extend south along the Gulf.
The western mountains are split in the middle into the main range of the Rockies and the coast ranges in California, Oregon, Washington, and British Columbia, with the Great Basin—a lower area containing smaller ranges and low-lying deserts—in between. The highest peak is Denali in Alaska.
The United States Geographical Survey (USGS) states that the geographic center of North America is "6 miles [10 km] west of Balta, Pierce County, North Dakota" at about 48°10′N 100°10′W, about 24 kilometres (15 mi) from Rugby, North Dakota. The USGS further states that "No marked or monumented point has been established by any government agency as the geographic center of either the 50 States, the conterminous United States, or the North American continent." Nonetheless, there is a 4.6-metre (15 ft) field stone obelisk in Rugby claiming to mark the center. The North American continental pole of inaccessibility is located 1,650 km (1,030 mi) from the nearest coastline, between Allen and Kyle, South Dakota at 43.36°N 101.97°W.


North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Tectonic Plate, Greenland is included as a part of North America geographically.
North America covers an area of about 24,709,000 square kilometres (9,540,000 square miles), about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in 23 independent states, or about 7.5% of the world's population. In human geography and in the English-speaking world outside the United States, particularly in Canada, "North America" and "North American" can refer to just Canada and the United States together.
North America was reached by its first human populations during the Last Glacial Period, via crossing the Bering land bridge approximately 20,000 to 17,000 years ago. The so-called Paleo-Indian period is taken to have lasted until about 10,000 years ago (the beginning of the Archaic or Meso-Indian period). The classic stage spans roughly the 6th to 13th centuries. The first recorded Europeans to visit North America (other than Greenland) were the Norse around 1000 AD. Christopher Columbus's arrival in 1492 sparked a transatlantic exchange which included migrations of European settlers during the Age of Discovery and the early modern period. Present-day cultural and ethnic patterns reflect interactions between European colonists, indigenous peoples, African slaves, immigrants from Europe, Asia, and the descendants of these groups.
Owing to Europe's colonization of the Americas, most North Americans speak European languages such as English, Spanish or French, and their cultures commonly reflect Western traditions. However, in parts of Canada, the United States, Mexico, and Central America, there are indigenous populations continuing their cultural traditions and speaking their own languages.


Geographically, the North American continent has many regions and subregions. These include cultural, economic, and geographic regions. Economic regions included those formed by trade blocs, such as the North American Trade Agreement bloc and Central American Trade Agreement. Linguistically and culturally, the continent could be divided into Anglo-America and Latin America. Anglo-America includes most of Northern America, Belize, and Caribbean islands with English-speaking populations (though sub-national entities, such as Louisiana and Quebec, have large Francophone populations; in Quebec, French is the sole official language).
The southern part of the North American continent is composed of two regions. These are Central America and the Caribbean. The north of the continent maintains recognized regions as well. In contrast to the common definition of "North America", which encompasses the whole continent, the term "North America" is sometimes used to refer only to Mexico, Canada, the United States, and Greenland.
The term Northern America refers to the northernmost countries and territories of North America: the United States, Bermuda, St. Pierre and Miquelon, Canada, and Greenland. Although the term does not refer to a unified region, Middle America—not to be confused with the Midwestern United States—groups the regions of Mexico, Central America, and the Caribbean.
North America's largest countries by land area, Canada and the United States, also have well-defined and recognized regions. In the case of Canada, these are (from east to west) Atlantic Canada, Central Canada, Canadian Prairies, the British Columbia Coast, and Northern Canada. These regions also contain many subregions. In the case of the United States—and in accordance with the US Census Bureau definitions—these regions are: New England, Mid-Atlantic, South Atlantic states, East North Central states, West North Central states, East South Central states, West South Central states, Mountain states, and Pacific states. Regions shared between both nations include the Great Lakes region. Megalopolises have formed between both nations in the case of the Pacific Northwest and the Great Lakes Megaregion.


Soil conditions for farming are generally good, especially downwind of volcanoes. This is largely because volcanic rocks are often rich in potassium bearing minerals such as orthoclase and decay easily. Volcanic debris, especially lahars, also have a leveling effect and the storage of water in the form of snow and ice is also important. These snow-capped mountains such as Mt. Hood and Mt. Bachelor are used as ski resorts in the late winter. While in the summer they become popular hiking and mountaineering locations. Much of that water eventually flows into reservoirs, where it is used for recreation before its potential energy is captured to generate hydroelectric power before being used to irrigate crops.
Because of the abundance of powerful streams, many of the major westward rivers off the Cascades have been dammed to provide hydroelectric power.  One of these, Ross Dam on the Skagit River, created a reservoir which spans the border southeast of Hope, British Columbia, extending 2 miles (3.2 km) into Canada.  At the foot of the southeast flank of Mount Baker, at Concrete, Washington, the Baker River is dammed to form Lake Shannon and Baker Lake.
In addition, there is a largely untapped amount of geothermal power that can be generated from the Cascades. The U.S. Geological Survey Geothermal Research Program has been investigating this potential. Some of this energy is already being used in places like Klamath Falls, Oregon, where volcanic steam is used to heat public buildings. The highest recorded temperature found in the range is 510 °F (266 °C) at 3,075 feet (937 m) below Newberry Volcano's caldera floor.


The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as the North Cascades, and the notable volcanoes known as the High Cascades. The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains. The latter term is also sometimes used by Washington residents to refer to the Washington section of the Cascades in addition to North Cascades, the more usual U.S. term, as in North Cascades National Park. The highest peak in the range is Mount Rainier in Washington at 14,411 feet (4,392 m).
The Cascades are part of the Pacific Ocean's Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. All of the eruptions in the contiguous United States over the last 200 years have been from Cascade volcanoes. The two most recent were Lassen Peak from 1914 to 1921 and a major eruption of Mount St. Helens in 1980. Minor eruptions of Mount St. Helens have also occurred since, most recently from 2004 to 2008. The Cascade Range is a part of the American Cordillera, a nearly continuous chain of mountain ranges (cordillera) that form the western "backbone" of North, Central, and South America.


The upheaval in the Spanish Empire that resulted in the independence of most of its New World territories was due to Napoleon Bonaparte's invasion of Spain in 1808. Napoleon forced the abdication of the Spanish monarch Charles IV and imposed of his brother Joseph Bonaparte as the Spanish king. Now with an alien usurper on the Spanish throne, there was a crisis of legitimacy of the monarchy, resulting in various responses in both Spain and Spanish America. In Mexico, elites argued that sovereignty now reverted to "the people" and that town councils (cabildos) were the most representative bodies.  American-born Spaniards petitioned the viceroy José de Iturrigaray (1803–08) to convene a junta to determine rule in Mexico in the current political crisis. Although Peninsular-born Spaniards were opposed to the plan, the viceroy called together wealthy landowners, miners, merchants, ecclesiastics, academics, and members of cabildos. They failed to come to agreement, and in the meantime, Peninsular-born Spaniards took the initiative, arresting Iturrigaray and leading creole elites in the capital. The coup ended what could have been a peaceful process toward political autonomy in Mexico.  Creoles now sought extralegal means to achieve their political aspirations.
On 16 September 1810, secular priest Miguel Hidalgo y Costilla declared against "bad government" in the small town of Dolores, Guanajuato. This event, known as the Cry of Dolores (Spanish: Grito de Dolores) is commemorated each year, on 16 September, as Mexico's independence day. The first insurgent group was formed by Hidalgo, army captain Ignacio Allende, the militia captain Juan Aldama and the wife of the local magistrate (Corregidor) Josefa Ortiz de Domínguez, known as La Corregidora. Hidalgo's local declaration sparked a huge revolt of the masses, an uncontrollable uprising targeting the persons and property of white elites, whether Peninsular- or American-born. Famously in Guanajuato, elites took refuge in the central grain storage (alhondiga), bringing their treasure, attempted to hold out against Hidalgo's followers, but were slaughtered. In an event emblematic of the war of independence, "Hidalgo's capture of the great silver city of Guanajuato on September 28, 1810, is the most famous single episode of the decade-long insurgency." Hidalgo and some of his soldiers were eventually captured, Hidalgo was defrocked, and they were executed by firing squad in Chihuahua, on 31 July 1811. The heads of the executed rebels were subsequently displayed on the granary. Following Hidalgo's death, Ignacio López Rayón and then by the priest José María Morelos assumed the leadership, occupying key southern cities with the support of Mariano Matamoros and Nicolás Bravo. In 1813 the Congress of Chilpancingo was convened and, on 6 November, signed the "Solemn Act of the Declaration of Independence of Northern America". This Act also called for the abolition of slavery and the system of racial hierarchy, and Roman Catholicism the sole religion. Morelos was captured and executed on 22 December 1815.
In subsequent years, the insurgency was a stalemate, but in 1820 when Spanish liberals seized power in Spain, and Mexican conservatives worried about the imposition of liberal principles overseas, including curtailment of the power of the Catholic Church.  Royalist criollo general Agustín de Iturbide was to continue fighting against Vicente Guerrero and insurgents in the south. Instead of attacking Guerrero, Itubide approached Guerrero to join forces to seize power in Mexico. Iturbide issued the Plan of Iguala on 24 February 1821. Sometimes called the Act of Independence, it called for  Roman Catholicism as the nation's sole religion; the establishment of a constitutional monarchy; and the equality of those born in Spain and those born in Mexico, the "three guarantees" can be summarized as "religion, independence, and union". All were to be equal citizens in the new sovereign nation, regardless of place of birth or racial category, a requirement that Guerrero, the mixed-race leader of the insurgency, insisted on for his joining with Iturbide. The flag of the newly formed Army of the Three Guarantees has evolved into today's Mexican flag.  On 24 August 1821 in incoming Viceroy and Iturbide signed the Treaty of Córdoba and the Declaration of Independence of the Mexican Empire", which recognized the independence of Mexico under the terms of the Plan of Iguala. The Spanish crown repudiated the 1821 treaty and did not formally recognize the independence of Mexico until 1836.


Mexico, officially the United Mexican States, is a country in the southern portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Mexico covers 1,972,550 square kilometers (761,610 sq mi), making it the world's 13th-largest country by area; with approximately 126,014,024 inhabitants, it is the 10th-most-populous country and has the most Spanish-speakers. Mexico is organized as a federal republic comprising 31 states and Mexico City, its capital. Other major urban areas include Monterrey, Guadalajara, Puebla, Toluca, Tijuana, Ciudad Juárez, and León.
Pre-Columbian Mexico traces its origins to 8,000 BCE and is identified as one of the world's six cradles of civilization. In particular, the Mesoamerican region was home to many intertwined civilizations; including the Olmec, Maya, Zapotec, Teotihuacan, and Purepecha. Last were the Aztecs, who dominated the region in the century before European contact. In 1521, the Spanish Empire and its indigenous allies conquered the Aztec Empire from its capital Tenochtitlan (now Mexico City), establishing the colony of New Spain.  Over the next three centuries, Spain and the Catholic Church played an important role expanding the territory, enforcing Christianity and spreading the Spanish language throughout. With the discovery of rich deposits of silver in Zacatecas and Guanajuato, New Spain soon became one of the most important mining centers worldwide. Wealth coming from Asia and the New World contributed to Spain's status as a major world power for the next centuries, and brought about a price revolution in Western Europe. The colonial order came to an end in the early nineteenth century with the War of Independence against Spain.
Mexico's early history as an independent nation state was marked by political and socioeconomic upheaval, both domestically and in foreign affairs. The Federal Republic of Central America shortly seceded the country. Then two invasions by foreign powers took place: first, by the United States as a consequence of the Texas Revolt by American settlers, which led to the Mexican–American War and huge territorial losses in 1848. After the introduction of liberal reforms in the Constitution of 1857, conservatives reacted with the war of Reform and prompted France to invade the country and install an Empire, against the Republican resistance led by liberal President Benito Juárez, which emerged victorious. The last decades of the 19th century were dominated by the dictatorship of Porfirio Díaz, who sought to modernize Mexico and restore order. However, the Porfiriato era led to great social unrest and ended with the outbreak in 1910 of the decade-long Mexican Revolution (civil war). This conflict had profound changes in Mexican society, including the proclamation of the 1917 Constitution, which remains in effect to this day. The remaining war generals ruled as a succession of presidents until the Institutional Revolutionary Party (PRI) emerged in 1929. The PRI in turn governed Mexico for the next 70 years, first under a set of paternalistic developmental policies of considerable economic success. During World War II Mexico also played an important role for the U.S. war effort. Nonetheless, the PRI regime resorted to repression and electoral fraud to maintain power; and moved the country to a more US-aligned neoliberal economic policy during the late 20th century. This culminated with the signing of the North American Free Trade Agreement in 1994, which caused a major indigenous rebellion in the state of Chiapas. PRI lost the presidency for the first time in 2000, against the conservative party (PAN).
Mexico is a developing country, ranking 74th on the Human Development Index, but has the world's 15th-largest economy by nominal GDP and the 11th-largest by PPP, with the United States being its largest economic partner. Its large economy and population, cultural influence, and steady democratization make Mexico a regional and middle power; it is often identified as an emerging power but is considered a newly industrialized state by several analysts. Mexico ranks first in the Americas and seventh in the world for the number of UNESCO World Heritage Sites. It is also one of the world's 17 megadiverse countries, ranking fifth in natural biodiversity. Mexico's rich cultural and biological heritage, as well as varied climate and geography, makes it a major tourist destination: as of 2018, it was the sixth most-visited country in the world, with 39 million international arrivals. However, the country continues to struggle with social inequality, poverty and extensive crime. It ranks poorly on the Global Peace Index, due in large part to ongoing conflict between the government and drug trafficking syndicates, which violently compete for the US drug market and trade routes. This "drug war" has led to over 120,000 deaths since 2006. Mexico is a member of United Nations, the G20, the Organisation for Economic Co-operation and Development (OECD), the World Trade Organization (WTO), the Asia-Pacific Economic Cooperation forum, the Organization of American States, Community of Latin American and Caribbean States, and the Organization of Ibero-American States.


The prehistory of Mexico stretches back millennia. The earliest human artifacts in Mexico are chips of stone tools found near campfire remains in the Valley of Mexico and radiocarbon-dated to circa 10,000 years ago. Mexico is the site of the domestication of maize, tomato, and beans, which produced an agricultural surplus. This enabled the transition from paleo-Indian hunter-gatherers to sedentary agricultural villages beginning around 5000 BCE.
In the subsequent formative eras, maize cultivation and cultural traits such as a mythological and religious complex, and a vigesimal (base 20) numeric system, were diffused from the Mexican cultures to the rest of the Mesoamerican culture area. In this period, villages became more dense in terms of population, becoming socially stratified with an artisan class, and developing into chiefdoms. The most powerful rulers had religious and political power, organizing the construction of large ceremonial centers.
The earliest complex civilization in Mexico was the Olmec culture, which flourished on the Gulf Coast from around 1500 BCE. Olmec cultural traits diffused through Mexico into other formative-era cultures in Chiapas, Oaxaca and the Valley of Mexico. The formative period saw the spread of distinct religious and symbolic traditions, as well as artistic and architectural complexes. The formative-era of Mesoamerica is considered one of the six independent cradles of civilization. In the subsequent pre-classical period, the Maya and Zapotec civilizations developed complex centers at Calakmul and Monte Albán, respectively. During this period the first true Mesoamerican writing systems were developed in the Epi-Olmec and the Zapotec cultures. The Mesoamerican writing tradition reached its height in the Classic Maya Hieroglyphic script. The earliest written histories date from this era. The tradition of writing was important after the Spanish conquest in 1521, with indigenous scribes learning to write their languages in alphabetic letters, while also continuing to create pictorial texts.
In Central Mexico, the height of the classic period saw the ascendancy of Teotihuacán, which formed a military and commercial empire whose political influence stretched south into the Maya area as well as north. Teotihuacan, with a population of more than 150,000 people, had some of the largest pyramidal structures in the pre-Columbian Americas. After the collapse of Teotihuacán around 600 AD, competition ensued between several important political centers in central Mexico such as Xochicalco and Cholula. At this time, during the Epi-Classic, Nahua peoples began moving south into Mesoamerica from the North, and became politically and culturally dominant in central Mexico, as they displaced speakers of Oto-Manguean languages. During the early post-classic era (ca. 1000–1519 CE), Central Mexico was dominated by the Toltec culture, Oaxaca by the Mixtec, and the lowland Maya area had important centers at Chichén Itzá and Mayapán. Toward the end of the post-Classic period, the Mexica established dominance, establishing a political and economic empire based in the city of Tenochtitlan (modern Mexico City), extending from central Mexico to the border with Guatemala. Alexander von Humboldt popularized the modern usage of "Aztec" as a collective term applied to all the people linked by trade, custom, religion, and language to the Mexica state and Ēxcān Tlahtōlōyān, the Triple Alliance. In 1843, with the publication of the work of William H. Prescott, it was adopted by most of the world, including 19th-century Mexican scholars who considered it a way to distinguish present-day Mexicans from pre-conquest Mexicans. This usage has been the subject of debate since the late 20th century.
The Aztec empire was an informal or hegemonic empire because it did not exert supreme authority over the conquered territories; it was satisfied with the payment of tributes from them. It was a discontinuous empire because not all dominated territories were connected; for example, the southern peripheral zones of Xoconochco were not in direct contact with the center. The hegemonic nature of the Aztec empire was demonstrated by their restoration of local rulers to their former position after their city-state was conquered. The Aztec did not interfere in local affairs, as long as the tributes were paid. The Aztec of Central Mexico built a tributary empire covering most of central Mexico. The Aztec were noted for practicing human sacrifice on a large scale. Along with this practice, they avoided killing enemies on the battlefield. Their warring casualty rate was far lower than that of their Spanish counterparts, whose principal objective was immediate slaughter during battle. This distinct Mesoamerican cultural tradition of human sacrifice ended with the gradually Spanish conquest in the 16th century. Other Mexican indigenous cultures were conquered and gradually subjected to Spanish colonial rule.
Since the colonial era and through to the twenty-first century, the indigenous roots of Mexican history and culture are essential to Mexican identity. The National Museum of Anthrology in Mexico City is the showcase of the nation's prehispanic glories. Historian Enrique Florescano calls it "a national treasure and a symbol of identity. The museum is the synthesis of an ideological, scientific, and political feat." Mexican Nobel laureate Octavio Paz said of the museum that the "exaltation and glorification of Mexico-Tenochtitlan transforms the Museum of Anthropology into a temple." Mexico pursued international recognition of its prehispanic heritage, and has a large number of UNESCO World Heritage Sites, the largest in the hemisphere. The existence of high indigenous civilization prior to the arrival of Europeans has also had an impact on European thought.


The overthrow of Santa Anna and the establishment of a civilian government by Liberals allowed them to enact laws that they considered vital for Mexico's economic development. It was a prelude to more civil wars and yet another foreign invasion. The Liberal Reform attempted to modernize Mexico's economy and institutions along liberal principles. They promulgated a new Constitution of 1857, separating Church and State, stripping the Conservative institutions of the Church and the military of their special privileges (fueros); mandating the sale of Church-owned property and sale of indigenous community lands, and secularizing education. Conservatives revolted, touching off civil war between rival Liberal and Conservative governments (1858–61).
The Liberals defeated the Conservative army on the battlefield, but Conservatives sought another solution to gain power via foreign intervention by the French. Mexican conservatives asked Emperor Napoleon III to place a European monarch as head of state in Mexico. The French Army defeated the Mexican Army and placed Maximilian Hapsburg on the newly established throne of Mexico, supported by Mexican Conservatives and propped up by the French Army. The Liberal republic under Benito Juárez was basically a government in internal exile, but with the end of the Civil War in the U.S. in April 1865, that government began aiding the Mexican Republic. Two years later, the French Army withdrew its support, Maximilian remained in Mexico rather than return to Europe. Republican forces captured him and he was executed in Querétaro, along with two Conservative Mexican generals. The "Restored Republic" saw the return of Juárez, who was "the personification of the embattled republic," as president.
The Conservatives had been not only defeated militarily, but also discredited politically for their collaboration with the French invaders. Liberalism became synonymous with patriotism. The Mexican Army that had its roots in the colonial royal army and then the army of the early republic was destroyed. New military leaders had emerged from the War of the Reform and the conflict with the French, most notably Porfirio Díaz, a hero of the Cinco de Mayo, who now sought civilian power. Juárez won re-election in 1867, but was challenged by Díaz, who criticized him for running for re-election. Díaz then rebelled, crushed by Juárez. Having won re-election, Juárez died in office of natural causes in July 1872, and Liberal Sebastián Lerdo de Tejada became president, declaring a "religion of state" for rule of law, peace, and order. When Lerdo ran for re-election, Díaz rebelled against the civilian president, issuing the Plan of Tuxtepec. Díaz had more support and waged guerrilla warfare against Lerdo. On the verge of Díaz's victory on the battlefield, Lerdo fled from office, going into exile.
After the turmoil in Mexico from 1810 to 1876, the 35-year rule of Liberal General Porfirio Díaz (r.1876–1911) allowed Mexico to rapidly modernize in a period characterized as one of "order and progress". The Porfiriato was characterized by economic stability and growth, significant foreign investment and influence, an expansion of the railroad network and telecommunications, and investments in the arts and sciences. The period was also marked by economic inequality and political repression. Díaz knew the potential for army rebellions, and systematically downsized the expenditure for the force, rather expanding the rural police force under direct control of the president. Díaz did not provoke the Catholic Church, coming to a modus vivendi with it; but he did not remove the anticlerical articles from the 1857 Constitution. From the late nineteenth century, Protestants began to make inroads into overwhelmingly Catholic Mexico.
The government encouraged British and U.S. investment. Commercial agriculture developed in northern Mexico, with many investors from the U.S. acquiring vast ranching estates and expanding irrigated cultivation of crops. The Mexican government ordered a survey of land with the aim of selling it for development. In this period, many indigenous communities lost their lands and the men became landless wage earners on large landed enterprises (haciendas). British and U.S. investors developed extractive mining of copper, lead, and other minerals, as well as petroleum on the Gulf Coast. Changes in Mexican law allowed for private enterprises to own the subsoil rights of land, rather than continuing the colonial law that gave all subsoil rights to the State. An industrial manufacturing sector also developed, particularly in textiles. At the same time, new enterprises gave rise to an industrial work force, which began organizing to gain labor rights and protections.
Díaz ruled with a group of advisors that became known as the científicos ("scientists"). The most influential científico was Secretary of Finance José Yves Limantour. The Porfirian regime was influenced by positivism. They rejected theology and idealism in favor of scientific methods being applied towards national development. As an integral aspect of the liberal project was secular education. The Díaz government led a protracted conflict against the Yaqui that culminated with the forced relocation of thousands of Yaqui to Yucatán and Oaxaca. Díaz's long success did not include planning for a political transition beyond his own presidency. He made no attempt, however, to establish a family dynasty, naming no relative as his successor. As the centennial of independence approached, Díaz gave an interview where he said he was not going to run in the 1910 elections, when he would be 80. Political opposition had been suppressed and there were few avenues for a new generation of leaders. But his announcement set off a frenzy of political activity, including the unlikely candidacy of the scion of a rich landowning family, Francisco I. Madero. Madero won a surprising amount of political support when Díaz changed his mind and ran in the election, jailing Madero. The September centennial celebration of independence was the last celebration of the Porfiriato. The Mexican Revolution starting in 1910 saw a decade of civil war, the "wind that swept Mexico."
