2001 (MMI) was a common year starting on Monday of the Gregorian calendar, the 2001st year of the Common Era (CE) and Anno Domini (AD) designations, the 1st  year of the 3rd millennium and the 21st century, and the  2nd   year of the 2000s decade.

The year 2001 is notable for the September 11th attacks on the World Trade Center and the Pentagon in the United States. 2001 was designated as International Year of Volunteers.


Linnaeus felt Uppsala was too noisy and unhealthy, so he bought two farms in 1758: Hammarby and Sävja. The next year, he bought a neighbouring farm, Edeby. He spent the summers with his family at Hammarby; initially it only had a small one-storey house, but in 1762 a new, larger main building was added. In Hammarby, Linnaeus made a garden where he could grow plants that could not be grown in the Botanical Garden in Uppsala. He began constructing a museum on a hill behind Hammarby in 1766, where he moved his library and collection of plants. A fire that destroyed about one third of Uppsala and had threatened his residence there necessitated the move.
Since the initial release of Systema Naturae in 1735, the book had been expanded and reprinted several times; the tenth edition was released in 1758. This edition established itself as the starting point for zoological nomenclature, the equivalent of Species Plantarum.
The Swedish King Adolf Frederick granted Linnaeus nobility in 1757, but he was not ennobled until 1761. With his ennoblement, he took the name Carl von Linné (Latinised as Carolus a Linné), 'Linné' being a shortened and gallicised version of 'Linnæus', and the German nobiliary particle 'von' signifying his ennoblement. The noble family's coat of arms prominently features a twinflower, one of Linnaeus's favourite plants; it was given the scientific name Linnaea borealis in his honour by Gronovius. The shield in the coat of arms is divided into thirds: red, black and green for the three kingdoms of nature (animal, mineral and vegetable) in Linnaean classification; in the centre is an egg "to denote Nature, which is continued and perpetuated in ovo." At the bottom is a phrase in Latin, borrowed from the Aeneid, which reads "Famam extendere factis": we extend our fame by our deeds. Linnaeus inscribed this personal motto in books that were given to him by friends.
After his ennoblement, Linnaeus continued teaching and writing. His reputation had spread over the world, and he corresponded with many different people. For example, Catherine II of Russia sent him seeds from her country. He also corresponded with Giovanni Antonio Scopoli, "the Linnaeus of the Austrian Empire", who was a doctor and a botanist in Idrija, Duchy of Carniola (nowadays Slovenia). Scopoli communicated all of his research, findings, and descriptions (for example of the olm and the dormouse, two little animals hitherto unknown to Linnaeus). Linnaeus greatly respected Scopoli and showed great interest in his work. He named a solanaceous genus, Scopolia, the source of scopolamine, after him, but because of the great distance between them, they never met.


Linnaeus was relieved of his duties in the Royal Swedish Academy of Science in 1763, but continued his work there as usual for more than ten years after. In 1769 he was elected to the American Philosophical Society for his work. He stepped down as rector at Uppsala University in December 1772, mostly due to his declining health.
Linnaeus's last years were troubled by illness. He had had a disease called the Uppsala fever in 1764, but survived due to the care of Rosén. He developed sciatica in 1773, and the next year, he had a stroke which partially paralysed him. He had a second stroke in 1776, losing the use of his right side and leaving him bereft of his memory; while still able to admire his own writings, he could not recognise himself as their author.
In December 1777, he had another stroke which greatly weakened him, and eventually led to his death on 10 January 1778 in Hammarby. Despite his desire to be buried in Hammarby, he was buried in Uppsala Cathedral on 22 January.
His library and collections were left to his widow Sara and their children. Joseph Banks, an eminent botanist, wished to purchase the collection, but his son Carl refused the offer and instead moved the collection to Uppsala. In 1783 Carl died and Sara inherited the collection, having outlived both her husband and son. She tried to sell it to Banks, but he was no longer interested; instead an acquaintance of his agreed to buy the collection. The acquaintance was a 24-year-old medical student, James Edward Smith, who bought the whole collection: 14,000 plants, 3,198 insects, 1,564 shells, about 3,000 letters and 1,600 books. Smith founded the Linnean Society of London five years later.
The von Linné name ended with his son Carl, who never married. His other son, Johannes, had died aged 3. There are over two hundred descendants of Linnaeus through two of his daughters.


In August 1735, during Linnaeus's stay with Burman, he met George Clifford III, a director of the Dutch East India Company and the owner of a rich botanical garden at the estate of Hartekamp in Heemstede. Clifford was very impressed with Linnaeus's ability to classify plants, and invited him to become his physician and superintendent of his garden. Linnaeus had already agreed to stay with Burman over the winter, and could thus not accept immediately. However, Clifford offered to compensate Burman by offering him a copy of Sir Hans Sloane's Natural History of Jamaica, a rare book, if he let Linnaeus stay with him, and Burman accepted. On 24 September 1735, Linnaeus moved to Hartekamp to become personal physician to Clifford, and curator of Clifford's herbarium. He was paid 1,000 florins a year, with free board and lodging. Though the agreement was only for a winter of that year, Linnaeus practically stayed there until 1738. It was here that he wrote a book Hortus Cliffortianus, in the preface of which he described his experience as "the happiest time of my life". (A portion of Hartekamp was declared as public garden in April 1956 by the Heemstede local authority, and was named "Linnaeushof". It eventually became, as it is claimed, the biggest playground in Europe.)
In July 1736, Linnaeus travelled to England, at Clifford's expense. He went to London to visit Sir Hans Sloane, a collector of natural history, and to see his cabinet, as well as to visit the Chelsea Physic Garden and its keeper, Philip Miller. He taught Miller about his new system of subdividing plants, as described in Systema Naturae. Miller was in fact reluctant to use the new binomial nomenclature, preferring the classifications of Joseph Pitton de Tournefort and John Ray at first. Linnaeus, nevertheless, applauded Miller's Gardeners Dictionary, The conservative Scot actually retained in his dictionary a number of pre-Linnaean binomial signifiers discarded by Linnaeus but which have been retained by modern botanists. He only fully changed to the Linnaean system in the edition of The Gardeners Dictionary of 1768.  Miller ultimately was impressed, and from then on started to arrange the garden according to Linnaeus's system.
Linnaeus also travelled to Oxford University to visit the botanist Johann Jacob Dillenius. He failed to make Dillenius publicly fully accept his new classification system, though the two men remained in correspondence for many years afterwards. Linnaeus dedicated his Critica Botanica to him, as "opus botanicum quo absolutius mundus non-vidit". Linnaeus would later name a genus of tropical tree Dillenia in his honour. He then returned to Hartekamp, bringing with him many specimens of rare plants. The next year, 1737, he published Genera Plantarum, in which he described 935 genera of plants, and shortly thereafter he supplemented it with Corollarium Generum Plantarum, with another sixty (sexaginta) genera.
His work at Hartekamp led to another book, Hortus Cliffortianus, a catalogue of the botanical holdings in the herbarium and botanical garden of Hartekamp. He wrote it in nine months (completed in July 1737), but it was not published until 1738. It contains the first use of the name Nepenthes, which Linnaeus used to describe a genus of pitcher plants.
Linnaeus stayed with Clifford at Hartekamp until 18 October 1737 (new style), when he left the house to return to Sweden. Illness and the kindness of Dutch friends obliged him to stay some months longer in Holland. In May 1738, he set out for Sweden again. On the way home, he stayed in Paris for about a month, visiting botanists such as Antoine de Jussieu. After his return, Linnaeus never left Sweden again.

Titled "An Expeditious Method of Conveying Intelligence", C.M. suggests that static electricity (generated by 1753 from "frictional machines") could send electric signals across wires to a receiver.  Rather than the dot and dash system later used by Samuel F.B. Morse, C.M. proposes that "a set of wires equal in number to the letters of the alphabet, be extended horizontally between two given places" and that on the receiving side, "Let a ball be suspended from every wire" and that a paper with a letter on it be underneath each wire.

December 11 – Major George Washington and British guide Christopher Gist arrive at Fort Le Boeuf (near modern-day Waterford, Pennsylvania and the city of Erie), a French fortress built in territory claimed by the British Crown Colony of Virginia.  Washington presents the fort's commander, French Army Captain Jacques Legardeur de Saint-Pierre, a message from Virginia's Lieutenant Governor Dinwiddie advising that "The lands upon the Ohio River are so notoriously known to be the property of the Crown of Great Britain that it is a matter of equal concern and surprise... to hear that a body of French fortresses and making settlements upon that river, within His Majesty's dominions," adding that "It becomes my duty to require your peaceable departure."  Captain Legardeur provides a reply for Washington to take to Dinwiddie, declaring that the rights of France's King Louis XV to the land "are incontestable", and refuses to back down, leading to beginning of the French and Indian War in 1754.


1753 (MDCCLIII) was a common year starting on Monday of the Gregorian calendar and a common year starting on Friday of the Julian calendar, the 1753rd year of the Common Era (CE) and Anno Domini (AD) designations, the 753rd  year of the 2nd millennium, the 53rd  year of the 18th century, and the  4th   year of the 1750s decade.

Under Peter the Great, Russia was proclaimed an empire in 1721, and established itself as one the European great powers. Ruling from 1682 to 1725, Peter defeated Sweden in the Great Northern War (1700–1721), securing Russia's access to the sea and sea trade. In 1703, on the Baltic Sea, Peter founded Saint Petersburg as Russia's new capital. Throughout his rule, sweeping reforms were made, which brought significant Western European cultural influences to Russia. The reign of Peter I's daughter Elizabeth in 1741–1762 saw Russia's participation in the Seven Years' War (1756–1763). During the conflict, Russian troops overran East Prussia, reaching Berlin. However, upon Elizabeth's death, all these conquests were returned to the Kingdom of Prussia by pro-Prussian Peter III of Russia.
Catherine II ("the Great"), who ruled in 1762–1796, presided over the Russian Age of Enlightenment. She extended Russian political control over the Polish–Lithuanian Commonwealth and annexed most of its territories into Russia, making it the most populous country in Europe. In the south, after the successful Russo-Turkish Wars against the Ottoman Empire, Catherine advanced Russia's boundary to the Black Sea, by dissolving the Crimean Khanate, and annexing Crimea. As a result of victories over Qajar Iran through the Russo-Persian Wars, by the first half of the 19th century, Russia also conquered the Caucasus. Catherine's successor, her son Paul, was unstable and focused predominantly on domestic issues. Following his short reign, Catherine's strategy was continued with Alexander I's (1801–1825) wresting of Finland from the weakened Sweden in 1809, and of Bessarabia from the Ottomans in 1812. In North America, the Russians became the first Europeans to reach and colonise Alaska. In 1803–1806, the first Russian circumnavigation was made. In 1820, a Russian expedition discovered the continent of Antarctica.
During the Napoleonic Wars, Russia joined alliances with various European powers, and fought against France. The French invasion of Russia at the height of Napoleon's power in 1812 reached Moscow, but eventually failed miserably as the obstinate resistance in combination with the bitterly cold Russian winter led to a disastrous defeat of invaders, in which the pan-European Grande Armée faced utter destruction. Led by Mikhail Kutuzov and Michael Andreas Barclay de Tolly, the Imperial Russian Army ousted Napoleon and drove throughout Europe in the War of the Sixth Coalition, ultimately entering Paris. Alexander I controlled Russia's delegation at the Congress of Vienna, which defined the map of post-Napoleonic Europe.
The officers who pursued Napoleon into Western Europe brought ideas of liberalism back to Russia, and attempted to curtail the tsar's powers during the abortive Decembrist revolt of 1825. At the end of the conservative reign of Nicholas I (1825–1855), a zenith period of Russia's power and influence in Europe, was disrupted by defeat in the Crimean War. Nicholas's successor Alexander II (1855–1881) enacted significant changes throughout the country, including the emancipation reform of 1861. These reforms spurred industrialisation, and modernised the Imperial Russian Army, which liberated much of the Balkans from Ottoman rule in the aftermath of the 1877–1878 Russo-Turkish War. During most of the 19th and early 20th century, Russia and Britain colluded over Afghanistan and its neighboring territories in Central and South Asia; the rivalry between the two major European empires came to be known as the Great Game.
The late 19th century saw the rise of various socialist movements in Russia. Alexander II was assassinated in 1881 by revolutionary terrorists. The reign of his son
Alexander III (1881–1894) was less liberal but more peaceful. Under last Russian emperor, Nicholas II (1894–1917), the Revolution of 1905 was triggered by the failure of the humiliating Russo-Japanese War .  The uprising was put down, but the government was forced to concede major reforms (Russian Constitution of 1906), including granting the freedoms of speech and assembly, the legalisation of political parties, and the creation of an elected legislative body, the State Duma.


In 1914, Russia entered World War I in response to Austria-Hungary's declaration of war on Russia's ally Serbia, and fought across multiple fronts while isolated from its Triple Entente allies. In 1916, the Brusilov Offensive of the Imperial Russian Army almost completely destroyed the Austro-Hungarian Army. However, the already-existing public distrust of the regime was deepened by the rising costs of war, high casualties, and rumors of corruption and treason. All this formed the climate for the Russian Revolution of 1917, carried out in two major acts. In early 1917, Nicholas II was forced to abdicate; he and his family were imprisoned and later executed in Yekaterinburg during the Russian Civil War. The monarchy was replaced by a shaky coalition of political parties that declared itself the Provisional Government. The Provisional Government proclaimed the Russian Republic in September. On 19 January [O.S. 6 January], 1918, the Russian Constituent Assembly declared Russia a democratic federal republic (thus ratifying the Provisional Government's decision). The next day the Constituent Assembly was dissolved by the All-Russian Central Executive Committee.
An alternative socialist establishment co-existed, the Petrograd Soviet, wielding power through the democratically elected councils of workers and peasants, called Soviets. The rule of the new authorities only aggravated the crisis in the country instead of resolving it, and eventually, the October Revolution, led by Bolshevik leader Vladimir Lenin, overthrew the Provisional Government and gave full governing power to the Soviets, leading to the creation of the world's first socialist state. The Russian Civil War broke out between the anti-communist White movement and the new Soviet regime with its Red Army. In the aftermath of signing the Treaty of Brest-Litovsk that concluded hostilities with the Central Powers of World War I; Bolshevist Russia surrendered most of its western territories, which hosted 34% of its population, 54% of its industries, 32% of its agricultural land, and roughly 90% of its coal mines.
The Allied powers launched an unsuccessful military intervention in support of anti-communist forces. In the meantime, both the Bolsheviks and White movement carried out campaigns of deportations and executions against each other, known respectively as the Red Terror and White Terror. By the end of the violent civil war, Russia's economy and infrastructure were heavily damaged, and as many as 10 million perished during the war, mostly civilians. Millions became White émigrés, and the Russian famine of 1921–1922 claimed up to five million victims.


The most powerful state to eventually arise after the destruction of Kievan Rus' was the Grand Duchy of Moscow, initially a part of Vladimir-Suzdal. While still under the domain of the Mongol-Tatars and with their connivance, Moscow began to assert its influence in the region in the early 14th century, gradually becoming the leading force in the process of the Rus' lands' reunification and expansion of Russia. Moscow's last rival, the Novgorod Republic, prospered as the chief fur trade centre and the easternmost port of the Hanseatic League.
Led by Prince Dmitry Donskoy of Moscow and helped by the Russian Orthodox Church, the united army of Russian principalities inflicted a milestone defeat on the Mongol-Tatars in the Battle of Kulikovo in 1380. Moscow gradually absorbed its parent Vladimir-Suzdal, and then surrounding principalities, including formerly strong rivals such as Tver and Novgorod.
Ivan III ("the Great") finally threw off the control of the Golden Horde and consolidated the whole of northern Rus' under Moscow's dominion, and was the first Russian ruler to take the title "Grand Duke of all Rus'". After the fall of Constantinople in 1453, Moscow claimed succession to the legacy of the Eastern Roman Empire. Ivan III married Sophia Palaiologina, the niece of the last Byzantine emperor Constantine XI, and made the Byzantine double-headed eagle his own, and eventually Russia's, coat-of-arms.


Russia (Russian: Россия, tr. Rossiya, [rɐˈsʲijə]), or the Russian Federation (RF), is a transcontinental country spanning Eastern Europe and Northern Asia. It is the largest country in the world by area, covering over 17,098,246 square kilometres (6,601,670 sq mi), and encompassing one-eighth of Earth's inhabitable landmass. Russia extends across eleven time zones and borders sixteen sovereign nations, the most of any country in the world. It is the ninth-most populous country in the world and the most populous country in Europe, with a population of 145.5 million. The country's capital and largest city is Moscow, the largest city entirely within Europe. Saint Petersburg is Russia's cultural centre and second-largest city. Other major urban areas include Novosibirsk, Yekaterinburg, Nizhny Novgorod and Kazan.
The East Slavs emerged as a recognisable group in Europe between the 3rd and 8th centuries AD. The medieval state of Kievan Rus' arose in the 9th century. In 988, it adopted Orthodox Christianity from the Byzantine Empire. Rus' ultimately disintegrated, and among its principalities, the Grand Duchy of Moscow rose and grew to become the Tsardom of Russia. By the early 18th century, Russia had vastly expanded through conquest, annexation, and exploration to evolve into the Russian Empire, the third-largest empire in history. The monarchy was abolished following the Russian Revolution in 1917, and the Russian SFSR became the world's first constitutionally socialist state. Following a civil war, the Russian SFSR established the Soviet Union with three other republics, as its largest and the principal constituent. The country underwent a period of rapid industrialisation at the expense of millions of lives. The Soviet Union played a decisive role in the Allied victory in World War II and emerged as a superpower and rival to the United States during the Cold War. The Soviet era saw some of the most significant technological achievements of the 20th century, including the world's first human-made satellite and the launching of the first human into space.
Following the dissolution of the Soviet Union in 1991, the newly independent Russian SFSR renamed itself the Russian Federation. In the aftermath of the constitutional crisis of 1993, a new constitution was adopted, and Russia has since been governed as a federal semi-presidential republic. Since his election in 2000, Vladimir Putin has dominated Russia's political system and Russia has experienced democratic backsliding, shifting into an authoritarian state. It ranks low in international measurements of freedom of the press and civil liberties and has high levels of perceived corruption.
The Russian economy is the world's eleventh-largest by nominal GDP and the sixth-largest by PPP. It is a recognised nuclear-weapons state, possessing the world's largest stockpile of nuclear weapons, with the fourth-highest military expenditure. Russia's extensive mineral and energy resources are the world's largest, and it is among the leading producers of oil and natural gas globally. It is a permanent member of the United Nations Security Council, a member of the G20, the SCO, BRICS, the APEC, the OSCE and the WTO, as well as the leading member of the CIS, the CSTO, and the EAEU,  Russia is also home of 30 UNESCO World Heritage Sites.


In development of the Third Rome ideas, the grand duke Ivan IV (the "Terrible") was officially crowned the first tsar of Russia in 1547. The tsar promulgated a new code of laws (Sudebnik of 1550), established the first Russian feudal representative body (Zemsky Sobor), revamped the military, curbed the influence of the clergy, and reorganised local government. During his long reign, Ivan nearly doubled the already large Russian territory by annexing the three Tatar khanates: Kazan and Astrakhan along the Volga, and the Khanate of Sibir in southwestern Siberia. Ultimately, by the end of the 16th century, Russia expanded east of the Ural Mountains. However, the Tsardom was weakened by the long and unsuccessful Livonian War against the coalition of the Kingdom of Poland and the Grand Duchy of Lithuania (later the united Polish–Lithuanian Commonwealth), the Kingdom of Sweden, and Denmark–Norway for access to the Baltic coast and sea trade. In 1572, an invading army of Crimean Tatars were thoroughly defeated in the crucial Battle of Molodi.
The death of Ivan's sons marked the end of the ancient Rurik dynasty in 1598, and in combination with the disastrous famine of 1601–1603, led to a civil war, the rule of pretenders, and foreign intervention during the Time of Troubles in the early 17th century. The Polish–Lithuanian Commonwealth, taking advantage, occupied parts of Russia, extending into the capital Moscow. In 1612, the Poles were forced to retreat by the Russian volunteer corps, led by merchant Kuzma Minin and prince Dmitry Pozharsky. The Romanov dynasty acceded to the throne in 1613 by the decision of Zemsky Sobor, and the country started its gradual recovery from the crisis.
Russia continued its territorial growth through the 17th century, which was the age of the Cossacks. In 1654, the Ukrainian leader, Bohdan Khmelnytsky, offered to place Ukraine under the protection of the Russian tsar, Alexis; whose acceptance of this offer led to another Russo-Polish War. Ultimately, Ukraine was split along the Dnieper, leaving the eastern part, (Left-bank Ukraine and Kiev) under Russian rule. In the east, the rapid Russian exploration and colonisation of vast Siberia continued, hunting for valuable furs and ivory. Russian explorers pushed eastward primarily along the Siberian River Routes, and by the mid-17th century, there were Russian settlements in eastern Siberia, on the Chukchi Peninsula, along the Amur River, and on the coast of the Pacific Ocean. In 1648, Semyon Dezhnyov became the first European to navigate through the Bering Strait.


The name Russia is derived from Rus', a medieval state populated primarily by the East Slavs. However, the proper name became more prominent in later history, and the country typically was called by its inhabitants "Rus land". This state is denoted as Kievan Rus' after its capital city by modern historiography. The name Rus' itself comes from the early medieval Rus' people, a group of Norse merchants and warriors who relocated from across the Baltic Sea and founded a state centred on Novgorod that later became Kievan Rus'.
A Medieval Latin version of the name Rus' was Ruthenia, which was used as one of several designations for East Slavic and Eastern Orthodox regions, and commonly as a designation for the lands of Rus'. The current name of the country, Россия (Rossiya), comes from the Byzantine Greek designation of the Rus', Ρωσσία Rossía – spelled Ρωσία (Rosía [roˈsia]) in Modern Greek. The standard way to refer to the citizens of Russia is "Russians" in English. There are two words in Russian which are commonly translated into English as "Russians" – one is "русские" (russkiye), which most often refers to ethnic Russians – and the other is "россияне" (rossiyane), which refers to citizens of Russia, regardless of ethnicity.


The peregrine falcon lives mostly along mountain ranges, river valleys, coastlines, and increasingly in cities. In mild-winter regions, it is usually a permanent resident, and some individuals, especially adult males, will remain on the breeding territory. Only populations that breed in Arctic climates typically migrate great distances during the northern winter.
The peregrine falcon reaches faster speeds than any other animal on the planet when performing the stoop, which involves soaring to a great height and then diving steeply at speeds of over 320 km/h (200 mph), hitting one wing of its prey so as not to harm itself on impact. The air pressure from such a dive could possibly damage a bird's lungs, but small bony tubercles on a falcon's nostrils are theorized to guide the powerful airflow away from the nostrils, enabling the bird to breathe more easily while diving by reducing the change in air pressure. To protect their eyes, the falcons use their nictitating membranes (third eyelids) to spread tears and clear debris from their eyes while maintaining vision. The distinctive malar stripe or 'moustache', a dark area of feathers below the eyes, is thought to reduce solar glare and improve contrast sensitivity when targeting fast moving prey in bright light condition; the malar stripe has been found to be wider and more pronounced in regions of the world with greater solar radiation supporting this solar glare hypothesis. Peregrine falcons have a flicker fusion frequency of 129 Hz (cycles per second), very fast for a bird of its size, and much faster than mammals. A study testing the flight physics of an "ideal falcon" found a theoretical speed limit at 400 km/h (250 mph) for low-altitude flight and 625 km/h (388 mph) for high-altitude flight. In 2005, Ken Franklin recorded a falcon stooping at a top speed of 389 km/h (242 mph).
The life span of peregrine falcons in the wild is up to 19 years 9 months. Mortality in the first year is 59–70%, declining to 25–32% annually in adults. Apart from such anthropogenic threats as collision with human-made objects, the peregrine may be killed by larger hawks and owls.


The peregrine falcon has a body length of 34 to 58 cm (13–23 in) and a wingspan from 74 to 120 cm (29–47 in). The male and female have similar markings and plumage but, as with many birds of prey, the peregrine falcon displays marked sexual dimorphism in size, with the female measuring up to 30% larger than the male. Males weigh 330 to 1,000 g (0.73–2.20 lb) and the noticeably larger females weigh 700 to 1,500 g (1.5–3.3 lb). In most subspecies, males weigh less than 700 g (1.5 lb) and females weigh more than 800 g (1.8 lb), and cases of females weighing about 50% more than their male breeding mates are not uncommon. The standard linear measurements of peregrines are: the wing chord measures 26.5 to 39 cm (10.4–15.4 in), the tail measures 13 to 19 cm (5.1–7.5 in) and the tarsus measures 4.5 to 5.6 cm (1.8–2.2 in).
The back and the long pointed wings of the adult are usually bluish black to slate grey with indistinct darker barring (see "Subspecies" below); the wingtips are black. The white to rusty underparts are barred with thin clean bands of dark brown or black. The tail, coloured like the back but with thin clean bars, is long, narrow, and rounded at the end with a black tip and a white band at the very end. The top of the head and a "moustache" along the cheeks are black, contrasting sharply with the pale sides of the neck and white throat. The cere is yellow, as are the feet, and the beak and claws are black. The upper beak is notched near the tip, an adaptation which enables falcons to kill prey by severing the spinal column at the neck. An immature bird is much browner, with streaked, rather than barred, underparts, and has a pale bluish cere and orbital ring.
A study shows that their black malar stripe exists to reduce glare from solar radiation, allowing them to see better. Photos from The Macaulay Library and iNaturalist showed that the malar stripe is thicker where there is more solar radiation. That supports the solar glare hypothesis.


The peregrine falcon is sexually mature at one to three years of age, but in larger populations they breed after two to three years of age. A pair mates for life and returns to the same nesting spot annually. The courtship flight includes a mix of aerial acrobatics, precise spirals, and steep dives. The male passes prey it has caught to the female in mid-air. To make this possible, the female actually flies upside-down to receive the food from the male's talons.
During the breeding season, the peregrine falcon is territorial; nesting pairs are usually more than 1 km (0.62 mi) apart, and often much farther, even in areas with large numbers of pairs. The distance between nests ensures sufficient food supply for pairs and their chicks. Within a breeding territory, a pair may have several nesting ledges; the number used by a pair can vary from one or two up to seven in a 16-year period. The peregrine falcon nests in a scrape, normally on cliff edges. The female chooses a nest site, where she scrapes a shallow hollow in the loose soil, sand, gravel, or dead vegetation in which to lay eggs. No nest materials are added. Cliff nests are generally located under an overhang, on ledges with vegetation. South-facing sites are favoured in the Northern Hemisphere. In some regions, as in parts of Australia and on the west coast of northern North America, large tree hollows are used for nesting. Before the demise of most European peregrines, a large population of peregrines in central and western Europe used the disused nests of other large birds. In remote, undisturbed areas such as the Arctic, steep slopes and even low rocks and mounds may be used as nest sites. In many parts of its range, peregrines now also nest regularly on tall buildings or bridges; these human-made structures used for breeding closely resemble the natural cliff ledges that the peregrine prefers for its nesting locations.
The pair defends the chosen nest site against other peregrines, and often against ravens, herons, and gulls, and if ground-nesting, also such mammals as foxes, wolverines, felids, bears, wolves, and mountain lions. Both nests and (less frequently) adults are predated by larger-bodied raptorial birds like eagles, large owls, or gyrfalcons. The most serious predators of peregrine nests in North America and Europe are the great horned owl and the Eurasian eagle owl. When reintroductions have been attempted for peregrines, the most serious impediments were these two species of owls routinely picking off nestlings, fledglings and adults by night. Peregrines defending their nests have managed to kill raptors as large as golden eagles and bald eagles (both of which they normally avoid as potential predators) that have come too close to the nest by ambushing them in a full stoop. In one instance, when a snowy owl killed a newly fledged peregrine, the larger owl was in turn killed by a stooping peregrine parent.
The date of egg-laying varies according to locality, but is generally from February to March in the Northern Hemisphere, and from July to August in the Southern Hemisphere, although the Australian subspecies macropus may breed as late as November, and equatorial populations may nest anytime between June and December. If the eggs are lost early in the nesting season, the female usually lays another clutch, although this is extremely rare in the Arctic due to the short summer season. Generally three to four eggs, but sometimes as few as one or as many as five, are laid in the scrape. The eggs are white to buff with red or brown markings. They are incubated for 29 to 33 days, mainly by the female, with the male also helping with the incubation of the eggs during the day, but only the female incubating them at night. The average number of young found in nests is 2.5, and the average number that fledge is about 1.5, due to the occasional production of infertile eggs and various natural losses of nestlings.
After hatching, the chicks (called "eyases") are covered with creamy-white down and have disproportionately large feet. The male (called the "tiercel") and the female (simply called the "falcon") both leave the nest to gather prey to feed the young. The hunting territory of the parents can extend a radius of 19 to 24 km (12 to 15 mi) from the nest site. Chicks fledge 42 to 46 days after hatching, and remain dependent on their parents for up to two months.


The peregrine falcon feeds almost exclusively on medium-sized birds such as pigeons and doves, phasianids, waterfowl, songbirds, and waders. This falcon tends to nest on tall buildings or bridges, and these urban dwelling birds subsist mostly on different pigeons. Worldwide, it is estimated that between 1,500 and 2,000 bird species (up to roughly a fifth of the world's bird species) are predated somewhere by these falcons. In North America, prey has varied in size from 3 g (0.11 oz) hummingbirds (Selasphorus and Archilochus ssp.) to a 3.1 kg (6.8 lb) sandhill crane (killed in Alaska by a peregrine in a stoop), although most prey taken by peregrines weigh from 20 g (0.71 oz) (small passerines) to 1,100 g (2.4 lb) (such as ducks and gulls). The peregrine falcon takes the most diverse range of bird species of any raptor in North America, with more than 300 species having fallen victim to the falcon, including nearly 100 shorebirds. Smaller hawks and owls are regularly predated, mainly smaller falcons such as the American kestrel, merlin and sharp-shinned hawks. In urban areas, the main component of the peregrine's diet is the rock or feral pigeon, which comprise 80% or more of the dietary intake for peregrines in some cities. Other common city birds are also taken regularly, including mourning doves, common wood pigeons, common swifts, northern flickers, common starlings, American robins, common blackbirds, and corvids (such as magpies, jays, or carrion, house, and American crows). Other than bats (in the genera Eptesicus, Myotis, Pipistrellus, and Tadarida) taken at night, the peregrine rarely hunts mammals, but will on occasion take small species such as rats, voles, lemmings, hares, shrews, mice and squirrels. Coastal populations of the large subspecies pealei feed almost exclusively on seabirds. In the Brazilian mangrove swamp of Cubatão, a wintering falcon of the subspecies tundrius was observed while successfully hunting a juvenile scarlet ibis. Insects and reptiles (such as small snakes) make up a small proportion of the diet, which varies greatly depending on what prey is available.
The peregrine falcon hunts most often at dawn and dusk, when prey are most active, but also nocturnally in cities, particularly during migration periods when hunting at night may become prevalent. Nocturnal migrants taken by peregrines include species as diverse as yellow-billed cuckoo, black-necked grebe, virginia rail, and common quail. The peregrine requires open space in order to hunt, and therefore often hunts over open water, marshes, valleys, fields, and tundra, searching for prey either from a high perch or from the air. Large congregations of migrants, especially species that gather in the open like shorebirds, can be quite attractive to hunting peregrines. Once prey is spotted, it begins its stoop, folding back the tail and wings, with feet tucked. Prey is typically struck and captured in mid-air; the peregrine falcon strikes its prey with a clenched foot, stunning or killing it with the impact, then turns to catch it in mid-air. If its prey is too heavy to carry, a peregrine will drop it to the ground and eat it there. If they miss the initial strike, peregrines will chase their prey in a twisting flight. Although previously thought rare, several cases of peregrines contour-hunting, i.e. using natural contours to surprise and ambush prey on the ground, have been reported and even rare cases of prey being pursued on foot. In addition, peregrines have been documented preying on chicks in nests, from birds such as kittiwakes. Prey is plucked before consumption. A recent study showed the presence of peregrines benefits non-preferred species while at the same time causing a decline in its preferred prey. As of 2018, the fastest recorded falcon was at 242 mph (nearly 390 km/h). Researchers at the University of Groningen in the Netherlands and at Oxford University used 3D computer simulations in 2018 to show that the high speed allows peregrines to gain better maneuverability and precision in strikes.


The accipitrine hawks generally hunt birds as their primary prey. They are also called "hen-hawks", or "wood-hawks" because of their woodland habitat.
The subfamily Accipitrinae contains Accipiter; it also contains genera Micronisus (Gabar goshawk), Urotriorchis (long-tailed hawk), and Megatriorchis (Doria's goshawk). Melierax (chanting goshawks) may be included in the subfamily, or given a subfamily of its own.
Erythrotriorchis (the red and chestnut-shouldered goshawks) is traditionally included in Accipitridae, but is possibly a convergent genus from an unrelated group (see red goshawk taxonomy).


Falconry was once called "hawking" and any bird used for falconry could be referred to as a hawk.
Aristotle listed eleven types of ἱέρακες (hierakes, hawks, singular ἱέραξ hierax): aisalōn (merlin), asterias, hypotriorchēs, kirkos, leios, perkos, phassophonos, phrynologos, pternis, spizias, and triorchēs. Pliny numbered sixteen kinds of hawks, but named only aigithos, epileios, kenchrēïs (kestrel), kybindis, and triorchēs (buzzard).


The Sapindaceae are a family of flowering plants in the order Sapindales known as the soapberry family. It contains 138 genera and 1858 accepted species. Examples include horse chestnut, maples, ackee and lychee.
The Sapindaceae occur in temperate to tropical regions, many in laurel forest habitat, throughout the world. Many are laticiferous, i.e. they contain latex, a milky sap, and many contain mildly toxic saponins with soap-like qualities in either the foliage and/or the seeds, or roots. The largest genera are Serjania, Paullinia, Allophylus, and Acer.


The Sapindaceae are related to the Rutaceae, and both are usually placed in an order Sapindales or Rutales, depending on whether they are kept separate and which name is used for the order. The most basal member appears to be Xanthoceras. Some authors formerly maintained some or all of Hippocastanaceae and Aceraceae, however this resulted in paraphyly. The former Ptaeroxylaceae, now placed in Rutaceae, were sometimes placed in Sapindaceae. The family is divided into four subfamilies, Dodonaeoideae (about 38 genera), Sapindoideae (about 114 genera), Hippocastanoideae (5 genera) and Xanthoceroideae (1 genus). The largest genera are Serjania (about 220 species), Paullinia (about 180 species),  and Allophylus (about 200 species) in the tropical Sapindoideae and Acer (about 110 species) in the temperate Hippocastanoideae.
The largely temperate genera formerly separated in the families Aceraceae (Acer, Dipteronia) and Hippocastanaceae (Aesculus, Billia, Handeliodendron) were included within a more broadly circumscribed Sapindaceae by the Angiosperm Phylogeny Group. Recent research has confirmed the inclusion of these genera in the Sapindaceae.


Plants of this family have a variety of habits, from trees to herbaceous plants to lianas. The leaves of the tropical genera are usually spirally alternate, while those of the temperate maples (Acer), Aesculus, and a few other genera are opposite. They are most often pinnately compound, but are palmately compound in Aesculus, and simply palmate in Acer. The petiole has a swollen base and lacks stipules. Some genera and species have laurel forest foliage due to convergent evolution.
The flowers are small and unisexual, or functionally unisexual, though plants may be either dioecious or monoecious. They are usually found in cymes grouped in panicles. They most often have four or five petals and sepals (petals are absent in Dodonaea). The stamens range from four to 10, usually on a nectar disc between the petals and stamens, their filaments are often hairy. The most frequent number is eight, in two rings of four. The gynoecium contains two or three carpels, sometimes up to six. The usually single style has a lobed stigma. Most often they are pollinated by birds or insects, with a few species pollinated by wind.
Ripe  fruits may be fleshy or dry. They may be nuts, berries, drupes, schizocarps, capsules (Bridgesia), or samaras (Acer). The embryos are bent or coiled, without endosperm in the seed, and frequently with an aril.


Before Greek poetry, the Aegean Sea area was in a Greek Dark Age, at the beginning of which syllabic writing was lost and alphabetic writing had not begun. Prior to then in the Bronze Age the records of the Assyrian Empire, the Hittite Empire and the various Mycenaean states of Greece mention a region undoubtedly Asia, certainly in Anatolia, including if not identical to Lydia. These records are administrative and do not include poetry.
The Mycenaean states were destroyed about 1200 BCE by unknown agents, though one school of thought assigns the Dorian invasion to this time. The burning of the palaces caused the  clay tablets holding the Mycenaean administrative records to be preserved by baking. These tablets were written in a Greek syllabic script called Linear B. This script was deciphered by a number of interested parties, most notably by a young World War II cryptographer, Michael Ventris, subsequently assisted by the scholar, John Chadwick.
A major cache discovered by Carl Blegen at the site of ancient Pylos included hundreds of male and female names formed by different methods. Some of these are of women held in servitude (as study of the society implied by the content reveals). They were used in trades, such as cloth-making, and usually came with children. The epithet lawiaiai, "captives", associated with some of them identifies their origin. Some are ethnic names. One in particular, aswiai, identifies "women of Asia". Perhaps they were captured in Asia, but some others, Milatiai, appear to have been of Miletus, a Greek colony, which would not have been raided for slaves by Greeks. Chadwick suggests that the names record the locations where these foreign women were purchased. The name is also in the singular, Aswia, which refers both to the name of a country and to a female from there. There is a masculine form, aswios. This Aswia appears to have been a remnant of a region known to the Hittites as Assuwa, centered on Lydia, or "Roman Asia". This name, Assuwa, has been suggested as the origin for the name of the continent "Asia". The Assuwa league was a confederation of states in western Anatolia, defeated by the Hittites under Tudhaliya I around 1400 BCE.


Asia (/ˈeɪʒə/ (listen), also UK: /ˈeɪʃə/) is Earth's largest and most populous continent, located primarily in the Eastern and Northern Hemispheres. It shares the continental landmass of Eurasia with the continent of Europe, and the continental landmass of Afro-Eurasia with Africa and Europe. Asia covers an area of 44,579,000 square kilometres (17,212,000 sq mi), about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitutes roughly 60% of the world's population.
In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, and ethnic differences, some of which vary on a spectrum rather than with a sharp dividing line. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish Straits, the Ural Mountains and Ural River, and to the south of the Caucasus Mountains and the Caspian and Black Seas, separating it from Europe.
China and India alternated in being the largest economies in the world from 1 to 1800 CE. China was a major economic power and attracted many to the east, and for many the legendary wealth and prosperity of the ancient culture of India personified Asia, attracting European commerce, exploration and colonialism. The accidental discovery of a trans-Atlantic route from Europe to America by Columbus while in search for a route to India demonstrates this deep fascination. The Silk Road became the main east–west trading route in the Asian hinterlands while the Straits of Malacca stood as a major sea route. Asia has exhibited economic dynamism (particularly East Asia) as well as robust population growth during the 20th century, but overall population growth has since fallen. Asia was the birthplace of most of the world's mainstream religions including Hinduism, Zoroastrianism, Judaism, Jainism, Buddhism, Confucianism, Taoism, Christianity, Islam, Sikhism, as well as many other religions.
Given its size and diversity, the concept of Asia—a name dating back to classical antiquity—may actually have more to do with human geography than physical geography. Asia varies greatly across and within its regions with regard to ethnic groups, cultures, environments, economics, historical ties and government systems. It also has a mix of many different climates ranging from the equatorial south via the hot desert in the Middle East, temperate areas in the east and the  continental centre to vast subarctic and polar areas in Siberia.


The boundary between Asia and Africa is the Red Sea, the Gulf of Suez, and the Suez Canal. This makes Egypt a transcontinental country, with the Sinai peninsula in Asia and the remainder of the country in Africa.


Latin Asia and Greek Ἀσία appear to be the same word. Roman authors translated Ἀσία as Asia. The Romans named a province Asia, located in western Anatolia (in modern-day Turkey). There was an Asia Minor and an Asia Major located in modern-day Iraq. As the earliest evidence of the name is Greek, it is likely circumstantially that Asia came from Ἀσία, but ancient transitions, due to the lack of literary contexts, are difficult to catch in the act. The most likely vehicles were the ancient geographers and historians, such as Herodotus, who were all Greek. Ancient Greek certainly evidences early and rich uses of the name.
The first continental use of Asia is attributed to Herodotus (about 440 BCE), not because he innovated it, but because his Histories are the earliest surviving prose to describe it in any detail. He defines it carefully, mentioning the previous geographers whom he had read, but whose works are now missing. By it he means Anatolia and the Persian Empire, in contrast to Greece and Egypt.
Herodotus comments that he is puzzled as to why three women's names were "given to a tract which is in reality one" (Europa, Asia, and Libya, referring to Africa), stating that most Greeks assumed that Asia was named after the wife of Prometheus (i.e. Hesione), but that the Lydians say it was named after Asies, son of Cotys, who passed the name on to a tribe at Sardis. In Greek mythology, "Asia" (Ἀσία) or "Asie" (Ἀσίη) was the name of a "Nymph or Titan goddess of Lydia".
In ancient Greek religion, places were under the care of female divinities, parallel to guardian angels. The poets detailed their doings and generations in allegoric language salted with entertaining stories, which subsequently playwrights transformed into classical Greek drama and became "Greek mythology". For example, Hesiod mentions the daughters of Tethys and Ocean, among whom are a "holy company", "who with the Lord Apollo and the Rivers have youths in their keeping". Many of these are geographic: Doris, Rhodea, Europa, Asia. Hesiod explains:
For there are three-thousand neat-ankled daughters of Ocean who are dispersed far and wide, and in every place alike serve the earth and the deep waters.
The Iliad (attributed by the ancient Greeks to Homer) mentions two Phrygians (the tribe that replaced the Luvians in Lydia) in the Trojan War named Asios (an adjective meaning "Asian"); and also a marsh or lowland containing a marsh in Lydia as ασιος. According to many Muslims, the term came from Ancient Egypt's Queen Asiya, the adoptive mother of Moses.


The threefold division of the Old World into Europe, Asia and Africa has been in use since the 6th century BC, due to Greek geographers such as Anaximander and Hecataeus. Anaximander placed the boundary between Asia and Europe along the Phasis River (the modern Rioni river) in Georgia of Caucasus (from its mouth by Poti on the Black Sea coast, through the Surami Pass and along the Kura River to the Caspian Sea), a convention still followed by Herodotus in the 5th century BC. During the Hellenistic period, this convention was revised, and the boundary between Europe and Asia was now considered to be the Tanais (the modern Don River). This is the convention used by Roman era authors such as Posidonius, Strabo and Ptolemy.
The border between Asia and Europe was historically defined by European academics. The Don River became unsatisfactory to northern Europeans when Peter the Great, king of the Tsardom of Russia, defeating rival claims of Sweden and the Ottoman Empire to the eastern lands, and armed resistance by the tribes of Siberia, synthesized a new Russian Empire extending to the Ural Mountains and beyond, founded in 1721. The major geographical theorist of the empire was a former Swedish prisoner-of-war, taken at the Battle of Poltava in 1709 and assigned to Tobolsk, where he associated with Peter's Siberian official, Vasily Tatishchev, and was allowed freedom to conduct geographical and anthropological studies in preparation for a future book.
In Sweden, five years after Peter's death, in 1730 Philip Johan von Strahlenberg published a new atlas proposing the Ural Mountains as the border of Asia. Tatishchev announced that he had proposed the idea to von Strahlenberg. The latter had suggested the Emba River as the lower boundary. Over the next century various proposals were made until the Ural River prevailed in the mid-19th century. The border had been moved perforce from the Black Sea to the Caspian Sea into which the Ural River projects. The border between the Black Sea and the Caspian is usually placed along the crest of the Caucasus Mountains, although it is sometimes placed further north.


The idea of a place called "Asia" was originally a concept of Greek civilization, though this might not correspond to the entire continent currently known by that name. The English word comes from Latin literature, where it has the same form, "Asia". Whether "Asia" in other languages comes from Latin of the Roman Empire is much less certain, and the ultimate source of the Latin word is uncertain, though several theories have been published. One of the first classical writers to use Asia as a name of the whole continent was Pliny. This metonymical change in meaning is common and can be observed in some other geographical names, such as Scandinavia (from Scania).


Geographical Asia is a cultural artifact of European conceptions of the world, beginning with the Ancient Greeks, being imposed onto other cultures, an imprecise concept causing endemic contention about what it means. Asia does not exactly correspond to the cultural borders of its various types of constituents.
From the time of Herodotus a minority of geographers have rejected the three-continent system (Europe, Africa, Asia) on the grounds that there is no substantial physical separation between them. For example, Sir Barry Cunliffe, the emeritus professor of European archeology at Oxford, argues that Europe has been geographically and culturally merely "the western excrescence of the continent of Asia".
Geographically, Asia is the major eastern constituent of the continent of Eurasia with Europe being a northwestern peninsula of the landmass. Asia, Europe and Africa make up a single continuous landmass—Afro-Eurasia (except for the Suez Canal)—and share a common continental shelf. Almost all of Europe and a major part of Asia sit atop the Eurasian Plate, adjoined on the south by the Arabian and Indian Plate and with the easternmost part of Siberia (east of the Chersky Range) on the North American Plate.


On March 2, 1861, the Nevada Territory separated from the Utah Territory and adopted its current name, shortened from The Sierra Nevada (Spanish for "snow-covered mountain range"). The 1861 southern boundary is commemorated by Nevada Historical Markers 57 and 58 in Lincoln and Nye counties.


Eight days before the presidential election of 1864, Nevada became the 36th state in the Union, despite lacking the minimum 60,000 residents that Congress typically required a potential state to have in order to become a state. (At the time, Nevada's population was little more than 10,000.) Governor Nye was frustrated that previous attempts to send the constitution via overland mail and by sea had failed by October 24, so on October 26 the full text was sent by telegraph at a cost of $4,303.27 – the most costly telegraph on file at the time for a single dispatch, equivalent to $74,556.44 in 2021. Finally, the response from Washington came on October 31, 1864: "the pain is over, the child is born, Nevada this day was admitted into the Union". Statehood was rushed to the date of October 31 to help ensure Abraham Lincoln's reelection on November 8 and post-Civil War Republican dominance in Congress, as Nevada's mining-based economy tied it to the more industrialized Union. As it turned out, however, Lincoln and the Republicans won the election handily and did not need Nevada's help.
Nevada is one of only two states to significantly expand its borders after admission to the Union, with the other being Missouri, which acquired additional territory in 1837 due to the Platte Purchase. In 1866 another part of the western Utah Territory was added to Nevada in the eastern part of the state, setting the current eastern boundary. Nevada achieved its current southern boundaries on January 18, 1867, when it absorbed the portion of Pah-Ute County in the Arizona Territory west of the Colorado River, essentially all of present-day Nevada south of the 37th parallel. The transfer was prompted by the discovery of gold in the area, and officials thought Nevada would be better able to oversee the expected population boom. This area includes most of what is now Clark County and the Las Vegas metropolitan area.
Mining shaped Nevada's economy for many years (see Silver mining in Nevada). When Mark Twain lived in Nevada during the period described in Roughing It, mining had led to an industry of speculation and immense wealth. Both mining and population temporarily declined in the late 19th century. However, the rich silver strike at Tonopah in 1900, followed by strikes in Goldfield and Rhyolite, created a second mining boom in  Nevada and Nevada's population.


Before the arrival of Europeans, the earliest inhabitants were Native American tribes including the Goshute, the Southern Paiute people, the Mohave people, and the Wašišiw (Washoe people).


The name "Nevada" comes from the Spanish adjective nevada [neˈβaða], meaning "snow-covered" or “snowy”. The state takes its name from the Nevada Territory, which in turn was named for the Sierra Nevada.
Nevadans pronounce the second syllable with the "a" of "apple" (/nɪˈvædə/) while some people from outside of the state pronounce it with the "a" of "palm" (/nɪˈvɑːdə/). Although the quality, but not the length, of the latter pronunciation could be perceived as closer to the Spanish pronunciation ([æ] is near-low front, [ɑ] is low back and [a] is low front, though often retracted to central [ä] in Spanish), it is not the pronunciation used by Nevadans. State Assemblyman Harry Mortenson proposed a bill to recognize the alternative pronunciation of Nevada, though the bill was not supported by most legislators and never received a vote. The Nevadan pronunciation is the one used by the state legislature. At one time, the state's official tourism organization, TravelNevada, stylized the name of the state as "Nevăda", with a breve over the a indicating the locally preferred pronunciation, which was also available as a license plate design until 2007.


Unregulated gambling was commonplace in the early Nevada mining towns but was outlawed in 1909 as part of a nationwide anti-gambling crusade. Because of subsequent declines in mining output and the decline of the agricultural sector during the Great Depression, Nevada again legalized gambling on March 19, 1931, with approval from the legislature. Governor Fred B. Balzar's signature enacted the most liberal divorce laws in the country and open gambling. The reforms came just eight days after the federal government presented the $49 million construction contract for Boulder Dam (now Hoover Dam).


The Nevada Test Site, 65 miles (105 km) northwest of the city of Las Vegas, was founded on January 11, 1951, for the testing of nuclear weapons. The site consists of about 1,350 square miles (3,500 km²) of the desert and mountainous terrain. Nuclear testing at the Nevada Test Site began with a 1 kiloton of TNT (4.2 TJ) nuclear bomb dropped on Frenchman Flat on January 27, 1951. The last atmospheric test was conducted on July 17, 1962, and the underground testing of weapons continued until September 23, 1992. The location is known for having the highest concentration of nuclear-detonated weapons in the U.S.
Over 80% of the state's area is owned by the federal government. The primary reason for this is homesteads were not permitted in large enough sizes to be viable in the arid conditions that prevail throughout desert Nevada. Instead, early settlers would homestead land surrounding a water source, and then graze livestock on the adjacent public land, which is useless for agriculture without access to water (this pattern of ranching still prevails).


Francisco Garcés was the first European in the area. Nevada was annexed as a part of the Spanish Empire in the northwestern territory of New Spain. Administratively, the area of Nevada was part of the Commandancy General of the Provincias Internas in the Viceroyalty of New Spain. Nevada became a part of Alta California (Upper California) province in 1804 when the Californias were split. With the Mexican War of Independence won in 1821, the province of Alta California became a territory (state) of Mexico, with a small population. Jedediah Smith entered the Las Vegas Valley in 1827, and Peter Skene Ogden traveled the Humboldt River in 1828. When the Mormons created the State of Deseret in 1847, they laid claim to all of Nevada within the Great Basin and the Colorado watershed. They also founded the first white settlement in what is now Nevada, Mormon Station (modern-day Genoa), in 1851. In June 1855, William Bringhurst and 29 fellow Mormon missionaries from Utah arrived at a site just northeast of downtown Las Vegas and built a 150-foot square adobe fort, the first permanent structure erected in the valley, which remained under the control of Salt Lake City until the winter of 1858–1859.
As a result of the Mexican–American War and the Treaty of Guadalupe Hidalgo, Mexico permanently lost Alta California in 1848. The new areas acquired by the United States continued to be administered as territories. As part of the Mexican Cession (1848) and the subsequent California Gold Rush that used Emigrant Trails through the area, the state's area evolved first as part of the Utah Territory, then the Nevada Territory (March 2, 1861; named for the Sierra Nevada).
The first discovery of a major U.S. deposit of silver ore occurred in Comstock Lode under Virginia City, Nevada, in 1859.


Cattle ranching has been central to Montana's history and economy since Johnny Grant began wintering cattle in the Deer Lodge Valley in the 1850s and traded cattle fattened in fertile Montana valleys with emigrants on the Oregon Trail. Nelson Story brought the first Texas Longhorn cattle into the territory in 1866. Granville Stuart, Samuel Hauser, and Andrew J. Davis started a major open-range cattle operation in Fergus County in 1879. The Grant-Kohrs Ranch National Historic Site in Deer Lodge is maintained today as a link to the ranching style of the late 19th century. Operated by the National Park Service, it is a 1,900-acre (7.7 km²) working ranch.


As settlers began populating Montana from the 1850s through the 1870s, disputes with Native Americans ensued, primarily over land ownership and control. In 1855, Washington Territorial Governor Isaac Stevens negotiated the Hellgate treaty between the United States government and the Salish, Pend d'Oreille, and Kootenai people of western Montana, which established boundaries for the tribal nations. The treaty was ratified in 1859. While the treaty established what later became the Flathead Indian Reservation, trouble with interpreters and confusion over the terms of the treaty led Whites to believe the Bitterroot Valley was opened to settlement, but the tribal nations disputed those provisions. The Salish remained in the Bitterroot Valley until 1891.
The first U.S. Army post established in Montana was Camp Cooke in 1866, on the Missouri River, to protect steamboat traffic to Fort Benton. More than a dozen additional military outposts were established in the state. Pressure over land ownership and control increased due to discoveries of gold in various parts of Montana and surrounding states. Major battles occurred in Montana during Red Cloud's War, the Great Sioux War of 1876, and the Nez Perce War and in conflicts with Piegan Blackfeet. The most notable were the Marias Massacre (1870), Battle of the Little Bighorn (1876), Battle of the Big Hole (1877), and Battle of Bear Paw (1877). The last recorded conflict in Montana between the U.S. Army and Native Americans occurred in 1887 during the Battle of Crow Agency in the Big Horn country. Indian survivors who had signed treaties were generally required to move onto reservations.
Simultaneously with these conflicts, bison, a keystone species and the primary protein source that Native people had survived on for many centuries, were being destroyed. Experts estimate that around 13 million bison roamed Montana in 1870. In 1875, General Philip Sheridan pleaded to a joint session of Congress to authorize the slaughtering of bison herds to deprive the Indians of their source of food. By 1884, commercial hunting had brought bison to the verge of extinction; only about 325 bison remained in the entire United States.


Various indigenous peoples have lived in the territory of the present-day state of Montana for thousands of years. Historic tribes encountered by Europeans and settlers from the United States included the Crow in the south-central area, the Cheyenne in the southeast, the Blackfeet, Assiniboine, and Gros Ventres in the central and north-central area, and the Kootenai and Salish in the west. The smaller Pend d'Oreille and Kalispel tribes lived near Flathead Lake and the western mountains, respectively. A part of southeastern Montana was used as a corridor between the Crows and the related Hidatsas in North Dakota.
As part of the Missouri River watershed, all of the land in Montana east of the Continental Divide was part of the Louisiana Purchase in 1803. Subsequent to and particularly in the decades following the Lewis and Clark Expedition, European, Canadian and American traders operated a fur trade, trading with indigenous peoples, in both eastern and western portions of what would become Montana. Though the increased interaction between fur traders and indigenous peoples frequently proved to be a profitable partnership, conflicts broke out when indigenous interests were threatened, such as the conflict between American trappers and the Blackfeet. Indigenous peoples in the region were also decimated by diseases introduced by fur traders to which they had no immunity. The trading post Fort Raymond (1807–1811) was constructed in Crow Indian country in 1807. Until the Oregon Treaty of 1846, land west of the continental divide was disputed between the British and U.S. governments and was known as the Oregon Country. The first permanent settlement by Euro-Americans in what today is Montana was St. Mary's, established in 1841 near present-day Stevensville. In 1847, Fort Benton was built as the uppermost fur-trading post on the Missouri River. In the 1850s, settlers began moving into the Beaverhead and Big Hole valleys from the Oregon Trail and into the Clark's Fork valley.
The first gold discovered in Montana was at Gold Creek near present-day Garrison in 1852.  Gold rushes to the region commenced in earnest starting in 1862.  A series of major mineral discoveries in the western part of the state found gold, silver, copper, lead, and coal (and later oil) which attracted tens of thousands of miners to the area. The richest of all gold placer diggings was discovered at Alder Gulch, where the town of Virginia City was established. Other rich placer deposits were found at Last Chance Gulch, where the city of Helena now stands, Confederate Gulch, Silver Bow, Emigrant Gulch, and Cooke City. Gold output between 1862 and 1876 reached $144 million, after which silver became even more important. The largest mining operations were at Butte, with important silver deposits and expansive copper deposits.


Montana (/mɒnˈtænə/ (listen)) is a state in the Mountain West subregion of the Western United States. It is bordered by Idaho to the west; North Dakota and South Dakota to the east; Wyoming to the south; and by the Canadian provinces of Alberta, British Columbia, and Saskatchewan to the north. It is the fourth-largest state by area, the eighth-least populous state, and the third-least densely populated state. Its state capital is Helena. The western half of Montana contains numerous mountain ranges, while the eastern half is characterized by western prairie terrain and badlands, with smaller mountain ranges found throughout the state. In all, 77 named ranges are part of the Rocky Mountains.
Montana has no official nickname but several unofficial ones, most notably "Big Sky Country", "The Treasure State", "Land of the Shining Mountains", and "The Last Best Place". The economy is primarily based on agriculture, including ranching and cereal grain farming. Other significant economic resources include oil, gas, coal, mining, and lumber. The health care, service, and government sectors are also significant to the state's economy. Montana's fastest-growing sector is tourism; nearly 13 million annual tourists visit Glacier National Park, Yellowstone National Park, Beartooth Highway, Flathead Lake, Big Sky Resort, and other attractions.


Tracks of the Northern Pacific Railroad (NPR) reached Montana from the west in 1881 and from the east in 1882. However, the railroad played a major role in sparking tensions with Native American tribes in the 1870s. Jay Cooke, the NPR president, launched major surveys into the Yellowstone valley in 1871, 1872, and 1873, which were challenged forcefully by the Sioux under chief Sitting Bull. These clashes, in part, contributed to the Panic of 1873, a financial crisis that delayed the construction of the railroad into Montana. Surveys in 1874, 1875, and 1876 helped spark the Great Sioux War of 1876. The transcontinental NPR was completed on September 8, 1883, at Gold Creek.
In 1881, the Utah and Northern Railway, a branch line of the Union Pacific, completed a narrow-gauge line from northern Utah to Butte. A number of smaller spur lines operated in Montana from 1881 into the 20th century, including the Oregon Short Line, Montana Railroad, and Milwaukee Road.
Tracks of the Great Northern Railroad (GNR) reached eastern Montana in 1887 and when they reached the northern Rocky Mountains in 1890, the GNR became a significant promoter of tourism to Glacier National Park region. The transcontinental GNR was completed on January 6, 1893, at Scenic, Washington and is known as the Hi Line, being the northern most transcontinental rail line in the United States.


The name Montana comes from the Spanish word montaña, which in turn comes from the Latin word montanea, meaning "mountain" or more broadly "mountainous country". Montaña del Norte was the name given by early Spanish explorers to the entire mountainous region of the west. The name Montana was added in 1863 to a bill by the United States House Committee on Territories (chaired at the time by James Ashley of Ohio) for the territory that would become Idaho Territory.
The name was changed by representatives Henry Wilson (Massachusetts) and Benjamin F. Harding (Oregon), who complained that Montana had "no meaning". When Ashley presented a bill to establish a temporary government in 1864 for a new territory to be carved out of Idaho, he again chose Montana Territory. This time, Rep. Samuel Cox, also of Ohio, objected to the name. Cox complained the name was a misnomer given that most of the territory was not mountainous and a Native American name would be more appropriate than a Spanish one. Other names such as Shoshone were suggested, but the Committee on Territories decided that they had discretion to choose the name, so the original name of Montana was adopted.


Alaska (/əˈlæskə/ (listen) ə-LAS-kə; Russian: Аляска, romanized: Alyaska; Aleut: Alax̂sxax̂; Inupiaq: Alaaskaq; Alutiiq: Alas'kaaq; Yup'ik: Alaskaq; Tlingit: Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest.
Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with a population of 736,081 as of 2020—more than quadruple the combined populations of Northern Canada and Greenland. Approximately half of Alaska's residents live within the Anchorage metropolitan area. The state capital of Juneau is the second-largest city in the United States by area, comprising more territory than the states of Rhode Island and Delaware. The former capital of Alaska, Sitka, is the largest U.S. city by area.
What is now Alaska has been home to various indigenous peoples for thousands of years; it is widely believed that the region served as the entry point for the initial settlement of North America by way of the Bering land bridge. The Russian Empire was the first to actively colonize the area beginning in the 18th century, eventually establishing Russian America, which spanned most of the current state. The expense and logistical difficulty of maintaining this distant possession prompted its sale to the U.S. in 1867 for US$7.2 million (equivalent to $140 million in 2021), or approximately two cents per acre ($4.74/km²). The area went through several administrative changes before becoming organized as a territory on May 11, 1912. It was admitted as the 49th state of the U.S. on January 3, 1959.
While it has one of the smallest state economies in the country, Alaska's per capita income is among the highest, owing to a diversified economy dominated by fishing, natural gas, and oil, all of which it has in abundance. United States armed forces bases and tourism are also a significant part of the economy; more than half the state is federally owned public land, including a multitude of national forests, national parks, and wildlife refuges.
The indigenous population of Alaska is proportionally the highest of any U.S. state, at over 15 percent. Close to two dozen native languages are spoken, and Alaskan Natives exercise considerable influence in local and state politics.


The 1968 discovery of oil at Prudhoe Bay and the 1977 completion of the Trans-Alaska Pipeline System led to an oil boom. Royalty revenues from oil have funded large state budgets from 1980 onward.
In 1989, the Exxon Valdez hit a reef in the Prince William Sound, spilling more than 11 million U.S. gallons (42 megaliters) of crude oil over 1,100 miles (1,800 km) of coastline. Today, the battle between philosophies of development and conservation is seen in the contentious debate over oil drilling in the Arctic National Wildlife Refuge and the proposed Pebble Mine.


Some researchers believe the first Russian settlement in Alaska was established in the 17th century. According to this hypothesis, in 1648 several koches of Semyon Dezhnyov's expedition came ashore in Alaska by storm and founded this settlement. This hypothesis is based on the testimony of Chukchi geographer Nikolai Daurkin, who had visited Alaska in 1764–1765 and who had reported on a village on the Kheuveren River, populated by "bearded men" who "pray to the icons". Some modern researchers associate Kheuveren with Koyuk River.
The first European vessel to reach Alaska is generally held to be the St. Gabriel under the authority of the surveyor M. S. Gvozdev and assistant navigator I. Fyodorov on August 21, 1732, during an expedition of Siberian Cossack A. F. Shestakov and Russian explorer Dmitry Pavlutsky (1729–1735). Another European contact with Alaska occurred in 1741, when Vitus Bering led an expedition for the Russian Navy aboard the St. Peter. After his crew returned to Russia with sea otter pelts judged to be the finest fur in the world, small associations of fur traders began to sail from the shores of Siberia toward the Aleutian Islands. The first permanent European settlement was founded in 1784.
Between 1774 and 1800, Spain sent several expeditions to Alaska to assert its claim over the Pacific Northwest. In 1789, a Spanish settlement and fort were built in Nootka Sound. These expeditions gave names to places such as Valdez, Bucareli Sound, and Cordova. Later, the Russian-American Company carried out an expanded colonization program during the early-to-mid-19th century. Sitka, renamed New Archangel from 1804 to 1867, on Baranof Island in the Alexander Archipelago in what is now Southeast Alaska, became the capital of Russian America. It remained the capital after the colony was transferred to the United States. The Russians never fully colonized Alaska, and the colony was never very profitable. Evidence of Russian settlement in names and churches survive throughout southeastern Alaska.
William H. Seward, the 24th United States Secretary of State, negotiated the Alaska Purchase (also known as Seward's Folly) with the Russians in 1867 for $7.2 million. Russia's contemporary ruler Tsar Alexander II, the Emperor of the Russian Empire, King of Poland and Grand Duke of Finland, also planned the sale; the purchase was made on March 30, 1867. Six months later the commissioners arrived in Sitka and the formal transfer was arranged; the formal flag-raising took place at Fort Sitka on October 18, 1867. In the ceremony 250 uniformed U.S. soldiers marched to the governor's house at "Castle Hill", where the Russian troops lowered the Russian flag and the U.S. flag was raised. This event is celebrated as Alaska Day, a legal holiday on October 18.
Alaska was loosely governed by the military initially, and was administered as a district starting in 1884, with a governor appointed by the United States president. A federal district court was headquartered in Sitka. For most of Alaska's first decade under the United States flag, Sitka was the only community inhabited by American settlers. They organized a "provisional city government", which was Alaska's first municipal government, but not in a legal sense. Legislation allowing Alaskan communities to legally incorporate as cities did not come about until 1900, and home rule for cities was extremely limited or unavailable until statehood took effect in 1959.


Numerous indigenous peoples occupied Alaska for thousands of years before the arrival of European peoples to the area. Linguistic and DNA studies done here have provided evidence for the settlement of North America by way of the Bering land bridge. At the Upward Sun River site in the Tanana Valley in Alaska, remains of a six-week-old infant were found. The baby's DNA showed that she belonged to a population that was genetically separate from other native groups present elsewhere in the New World at the end of the Pleistocene. Ben Potter, the University of Alaska Fairbanks archaeologist who unearthed the remains at the Upward Sun River site in 2013, named this new group Ancient Beringians.
The Tlingit people developed a society with a matrilineal kinship system of property inheritance and descent in what is today Southeast Alaska, along with parts of British Columbia and the Yukon. Also in Southeast were the Haida, now well known for their unique arts. The Tsimshian people came to Alaska from British Columbia in 1887, when President Grover Cleveland, and later the U.S. Congress, granted them permission to settle on Annette Island and found the town of Metlakatla. All three of these peoples, as well as other indigenous peoples of the Pacific Northwest Coast, experienced smallpox outbreaks from the late 18th through the mid-19th century, with the most devastating epidemics occurring in the 1830s and 1860s, resulting in high fatalities and social disruption.
The Aleutian Islands are still home to the Aleut people's seafaring society, although they were the first Native Alaskans to be exploited by the Russians. Western and Southwestern Alaska are home to the Yup'ik, while their cousins the Alutiiq ~ Sugpiaq live in what is now Southcentral Alaska. The Gwich'in people of the northern Interior region are Athabaskan and primarily known today for their dependence on the caribou within the much-contested Arctic National Wildlife Refuge. The North Slope and Little Diomede Island are occupied by the widespread Inupiat people.


Statehood for Alaska was an important cause of James Wickersham early in his tenure as a congressional delegate. Decades later, the statehood movement gained its first real momentum following a territorial referendum in 1946. The Alaska Statehood Committee and Alaska's Constitutional Convention would soon follow. Statehood supporters also found themselves fighting major battles against political foes, mostly in the U.S. Congress but also within Alaska. Statehood was approved by the U.S. Congress on July 7, 1958; Alaska was officially proclaimed a state on January 3, 1959.


The name "Alaska" (Russian: Аля́ска, tr. Alyáska) was introduced in the Russian colonial period when it was used to refer to the Alaska Peninsula. It was derived from an Aleut-language idiom, "alaxsxaq", meaning "the mainland" or, more literally, "the object towards which the action of the sea is directed". It is also known as "Alyeska", the "great land", an Aleut word derived from the same root.


Starting in the 1890s and stretching in some places to the early 1910s, gold rushes in Alaska and the nearby Yukon Territory brought thousands of miners and settlers to Alaska. Alaska was officially incorporated as an organized territory in 1912. Alaska's capital, which had been in Sitka until 1906, was moved north to Juneau. Construction of the Alaska Governor's Mansion began that same year. European immigrants from Norway and Sweden also settled in southeast Alaska, where they entered the fishing and logging industries.
During World War II, the Aleutian Islands Campaign focused on Attu, Agattu and Kiska, all which were occupied by the Empire of Japan. During the Japanese occupation, a white American civilian and two United States Navy personnel were killed at Attu and Kiska respectively, and nearly a total of 50 Aleut civilians and eight sailors were interned in Japan. About half of the Aleuts died during the period of internment. Unalaska/Dutch Harbor and Adak became significant bases for the United States Army, United States Army Air Forces and United States Navy. The United States Lend-Lease program involved flying American warplanes through Canada to Fairbanks and then Nome; Soviet pilots took possession of these aircraft, ferrying them to fight the German invasion of the Soviet Union. The construction of military bases contributed to the population growth of some Alaskan cities.


On March 27, 1964, the massive Good Friday earthquake killed 133 people and destroyed several villages and portions of large coastal communities, mainly by the resultant tsunamis and landslides. It was the second-most-powerful earthquake in recorded history, with a moment magnitude of 9.2 (more than a thousand times as powerful as the 1989 San Francisco earthquake). The time of day (5:36 pm), time of year (spring) and location of the epicenter were all cited as factors in potentially sparing thousands of lives, particularly in Anchorage.
Lasting four minutes and thirty-eight seconds, the magnitude 9.2 megathrust earthquake remains the most powerful earthquake recorded in North American history, and the second most powerful earthquake recorded in world history. Six hundred miles (970 km) of fault ruptured at once and moved up to 60 ft (18 m), releasing about 500 years of stress buildup. Soil liquefaction, fissures, landslides, and other ground failures caused major structural damage in several communities and much damage to property. Anchorage sustained great destruction or damage to many inadequately earthquake-engineered houses, buildings, and infrastructure (paved streets, sidewalks, water and sewer mains, electrical systems, and other man-made equipment), particularly in the several landslide zones along Knik Arm. Two hundred miles (320 km) southwest, some areas near Kodiak were permanently raised by 30 feet (9 m). Southeast of Anchorage, areas around the head of Turnagain Arm near Girdwood and Portage dropped as much as 8 feet (2.4 m), requiring reconstruction and fill to raise the Seward Highway above the new high tide mark.
In Prince William Sound, Port Valdez suffered a massive underwater landslide, resulting in the deaths of 32 people between the collapse of the Valdez city harbor and docks, and inside the ship that was docked there at the time. Nearby, a 27-foot (8.2 m) tsunami destroyed the village of Chenega, killing 23 of the 68 people who lived there; survivors out-ran the wave, climbing to high ground. Post-quake tsunamis severely affected Whittier, Seward, Kodiak, and other Alaskan communities, as well as people and property in British Columbia, Washington, Oregon, and California. Tsunamis also caused damage in Hawaii and Japan. Evidence of motion directly related to the earthquake was also reported from Florida and Texas.


Following several constitutional conferences, the British North America Act 1867 officially proclaimed Canadian Confederation on July 1, 1867, initially with four provinces: Ontario, Quebec, Nova Scotia, and New Brunswick. Canada assumed control of Rupert's Land and the North-Western Territory to form the Northwest Territories, where the Métis' grievances ignited the Red River Rebellion and the creation of the province of Manitoba in July 1870. British Columbia and Vancouver Island (which had been united in 1866) joined the confederation in 1871 on the promise of a transcontinental railway extending to Victoria in the province within 10 years, while Prince Edward Island joined in 1873. In 1898, during the Klondike Gold Rush in the Northwest Territories, Parliament created the Yukon Territory. Alberta and Saskatchewan became provinces in 1905. Between 1871 and 1896, almost one quarter of the Canadian population emigrated south to the U.S.
To open the West and encourage European immigration, Parliament approved sponsoring the construction of three transcontinental railways (including the Canadian Pacific Railway), opening the prairies to settlement with the Dominion Lands Act, and establishing the North-West Mounted Police to assert its authority over this territory. This period of westward expansion and nation building resulted in the displacement of many Indigenous peoples of the Canadian Prairies to "Indian reserves", clearing the way for ethnic European block settlements. This caused the collapse of the Plains Bison in western Canada and the introduction of European cattle farms and wheat fields dominating the land. The Indigenous peoples saw widespread famine and disease due to the loss of the bison and their traditional hunting lands. The federal government did provide emergency relief, on condition of the Indigenous peoples moving to the reserves. During this time, Canada introduced the Indian Act extending its control over the First Nations to education, government and legal rights.
