Plant organs can grow according to two different schemes, namely monopodial or racemose and sympodial or cymose. In inflorescences these two different growth patterns are called indeterminate and determinate respectively, and indicate whether a terminal flower is formed and where flowering starts within the inflorescence.
Indeterminate inflorescence: Monopodial (racemose) growth. The terminal bud keeps growing and forming lateral flowers. A terminal flower is never formed.
Determinate inflorescence: Sympodial (cymose) growth. The terminal bud forms a terminal flower and then dies out. Other flowers then grow from lateral buds.
Indeterminate and determinate inflorescences are sometimes referred to as open and closed inflorescences respectively. The indeterminate patterning of flowers is derived from determinate flowers. It is suggested that indeterminate flowers have a common mechanism that prevents terminal flower growth. Based on phylogenetic analyses, this mechanism arose independently multiple times in different species.
In an indeterminate inflorescence there is no true terminal flower and the stem usually has a rudimentary end. In many cases the last true flower formed by the terminal bud (subterminal flower) straightens up, appearing to be a terminal flower. Often a vestige of the terminal bud may be noticed higher on the stem.
In determinate inflorescences the terminal flower is usually the first to mature (precursive development), while the others tend to mature starting from the base of the stem. This pattern is called acropetal maturation. When flowers start to mature from the top of the stem, maturation is basipetal, whereas when the central mature first, maturation is divergent.


Inflorescences are described by many different characteristics including how the flowers are arranged on the peduncle, the blooming order of the flowers and how different clusters of flowers are grouped within it. These terms are general representations as plants in nature can have a combination of types. These structural types are largely based on natural selection.


Determinate simple inflorescences are generally called cymose. The main kind of cymose inflorescence is the cyme (pronounced 'saim', from the Latin cyma in the sense 'cabbage sprout', from Greek kuma 'anything swollen'). Cymes are further divided according to this scheme:
Only one secondary axis: monochasium
Secondary buds always develop on the same side of the stem: helicoid cyme or bostryx
The successive pedicels are aligned on the same plane: drepanium
Secondary buds develop alternately on the stem : scorpioid cyme
The successive pedicels are arranged in a sort of spiral: cincinnus (characteristic of the Boraginaceae and Commelinaceae)
The successive pedicels follow a zig-zag path on the same plane: rhipidium (many Iridaceae)
Two secondary axes: dichasial cyme
Secondary axis still dichasial: dichasium (characteristic of Caryophyllaceae)
Secondary axis monochasia: double scorpioid cyme or double helicoid cyme
More than two secondary axes: pleiochasium
A cyme can also be so compressed that it looks like an umbel. Strictly speaking this kind of inflorescence could be called umbelliform cyme, although it is normally called simply 'umbel'.
Another kind of definite simple inflorescence is the raceme-like cyme or botryoid; that is as a raceme with a terminal flower and is usually improperly called 'raceme'.
A reduced raceme or cyme that grows in the axil of a bract is called a fascicle. A verticillaster is a fascicle with the structure of a dichasium; it is common among the Lamiaceae. Many verticillasters with reduced bracts can form a spicate (spike-like) inflorescence that is commonly called a spike.

The prevalent definition of Europe as a geographical term has been in use since the mid-19th century.
Europe is taken to be bounded by large bodies of water to the north, west and south; Europe's limits to the east and north-east are usually taken to be the Ural Mountains, the Ural River and the Caspian Sea; to the south-east, the Caucasus Mountains, the Black Sea and the waterways connecting the Black Sea to the Mediterranean Sea.
Islands are generally grouped with the nearest continental landmass, hence Iceland is considered to be part of Europe, while the nearby island of Greenland is usually assigned to North America, although politically belonging to Denmark. Nevertheless, there are some exceptions based on sociopolitical and cultural differences. Cyprus is closest to Anatolia (or Asia Minor), but is considered part of Europe politically and it is a member state of the EU. Malta was considered an island of North-western Africa for centuries, but now it is considered to be part of Europe as well.
"Europe", as used specifically in British English, may also refer to Continental Europe exclusively.
The term "continent" usually implies the physical geography of a large land mass completely or almost completely surrounded by water at its borders. Prior to the adoption of the current convention that includes mountain divides, the border between Europe and Asia had been redefined several times since its first conception in classical antiquity, but always as a series of rivers, seas and straits that were believed to extend an unknown distance east and north from the Mediterranean Sea without the inclusion of any mountain ranges. Cartographer Herman Moll suggested in 1715 Europe was bounded by a series of partly-joined waterways directed towards the Turkish straits, and the Irtysh River draining into the upper part of the Ob River and the Arctic Ocean. In contrast, the present eastern boundary of Europe partially adheres to the Ural and Caucasus Mountains, which is somewhat arbitrary and inconsistent compared to any clear-cut definition of the term "continent".
The current division of Eurasia into two continents now reflects East-West cultural, linguistic and ethnic differences which vary on a spectrum rather than with a sharp dividing line. The geographic border between Europe and Asia does not follow any state boundaries and now only follows a few bodies of water. Turkey is generally considered a transcontinental country divided entirely by water, while Russia and Kazakhstan are only partly divided by waterways. France, the Netherlands, Portugal, Spain and the United Kingdom are also transcontinental (or more properly, intercontinental, when oceans or large seas are involved) in that their main land areas are in Europe while pockets of their territories are located on other continents separated from Europe by large bodies of water. Spain, for example, has territories south of the Mediterranean Sea—namely, Ceuta and Melilla—which are parts of Africa and share a border with Morocco. According to the current convention, Georgia and Azerbaijan are transcontinental countries where waterways have been completely replaced by mountains as the divide between continents.


Ancient Greece was the founding culture of Western civilisation. Western democratic and rationalist culture are often attributed to Ancient Greece. The Greek city-state, the polis, was the fundamental political unit of classical Greece. In 508 BCE, Cleisthenes instituted the world's first democratic system of government in Athens. The Greek political ideals were rediscovered in the late 18th century by European philosophers and idealists. Greece also generated many cultural contributions: in philosophy, humanism and rationalism under Aristotle, Socrates and Plato; in history with Herodotus and Thucydides; in dramatic and narrative verse, starting with the epic poems of Homer; in drama with Sophocles and Euripides, in medicine with Hippocrates and Galen; and in science with Pythagoras, Euclid and Archimedes. In the course of the 5th century BCE, several of the Greek city states would ultimately check the Achaemenid Persian advance in Europe through the Greco-Persian Wars, considered a pivotal moment in world history, as the 50 years of peace that followed are known as Golden Age of Athens, the seminal period of ancient Greece that laid many of the foundations of Western civilisation.
Greece was followed by Rome, which left its mark on law, politics, language, engineering, architecture, government and many more key aspects in western civilisation. By 200 BCE, Rome had conquered Italy and over the following two centuries it conquered Greece and Hispania (Spain and Portugal), the North African coast, much of the Middle East, Gaul (France and Belgium) and Britannia (England and Wales).
Expanding from their base in central Italy beginning in the third century BCE, the Romans gradually expanded to eventually rule the entire Mediterranean Basin and Western Europe by the turn of the millennium. The Roman Republic ended in 27 BCE, when Augustus proclaimed the Roman Empire. The two centuries that followed are known as the pax romana, a period of unprecedented peace, prosperity and political stability in most of Europe. The empire continued to expand under emperors such as Antoninus Pius and Marcus Aurelius, who spent time on the Empire's northern border fighting Germanic, Pictish and Scottish tribes. Christianity was legalised by Constantine I in 313 CE after three centuries of imperial persecution. Constantine also permanently moved the capital of the empire from Rome to the city of Byzantium (modern-day Istanbul) which was renamed Constantinople in his honour in 330 CE. Christianity became the sole official religion of the empire in 380 CE and in 391–392 CE, the emperor Theodosius outlawed pagan religions. This is sometimes considered to mark the end of antiquity; alternatively antiquity is considered to end with the fall of the Western Roman Empire in 476 CE; the closure of the pagan Platonic Academy of Athens in 529 CE; or the rise of Islam in the early 7th century CE.  During most of its existence, the Byzantine Empire was one of the most powerful economic, cultural, and military forces in Europe.


Europe is a landmass, which is either considered a continent in its own right or a subcontinent of Eurasia, located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Asia and Africa. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. Although much of this border is over land, Europe is almost always recognised as its own continent because of its great physical size and the weight of its history and traditions. Europe can also be viewed as a subcontinent of Eurasia, and referred to as the European subcontinent.
Europe covers about 10.18 million km² (3.93 million sq mi), or 2% of Earth's surface (6.8% of land area), making it the second-smallest continent (using the seven-continent model). Politically, Europe is divided into about fifty sovereign states, of which Russia is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a total population of about 745 million (about 10% of the world population) in 2021. The European climate is largely affected by warm Atlantic currents that temper winters and summers on much of the continent, even at latitudes along which the climate in Asia and North America is severe. Further from the sea, seasonal differences are more noticeable than close to the coast.
European culture is the root of Western civilisation, which traces its lineage back to ancient Greece and ancient Rome. The fall of the Western Roman Empire in 476 AD and the subsequent Migration Period marked the end of Europe's ancient history, and the beginning of the Middle Ages. Renaissance humanism, exploration, art, and science led to the modern era. Since the Age of Discovery, started by Portugal and Spain, Europe played a predominant role in global affairs. Between the 16th and 20th centuries, European powers colonised at various times the Americas, almost all of Africa and Oceania, and the majority of Asia.
The Age of Enlightenment, the subsequent French Revolution and the Napoleonic Wars shaped the continent culturally, politically and economically from the end of the 17th century until the first half of the 19th century. The Industrial Revolution, which began in Great Britain at the end of the 18th century, gave rise to radical economic, cultural and social change in Western Europe and eventually the wider world. Both world wars took place for the most part in Europe, contributing to a decline in Western European dominance in world affairs by the mid-20th century as the Soviet Union and the United States took prominence. During the Cold War, Europe was divided along the Iron Curtain between NATO in the West and the Warsaw Pact in the East, until the Revolutions of 1989, fall of the Berlin Wall and the dissolution of the Soviet Union.
In 1949, the Council of Europe was founded with the idea of unifying Europe to achieve common goals and prevent future wars. Further European integration by some states led to the formation of the European Union (EU), a separate political entity that lies between a confederation and a federation. The EU originated in Western Europe but has been expanding eastward since the fall of the Soviet Union in 1991. The currency of most countries of the European Union, the euro, is the most commonly used among Europeans; and the EU's Schengen Area abolishes border and immigration controls between most of its member states, and some non-member states. There exists a political movement favouring the evolution of the European Union into a single federation encompassing much of the continent.


During the 2.5 million years of the Pleistocene, numerous cold phases called glacials (Quaternary ice age), or significant advances of continental ice sheets, in Europe and North America, occurred at intervals of approximately 40,000 to 100,000 years. The long glacial periods were separated by more temperate and shorter interglacials which lasted about 10,000–15,000 years. The last cold episode of the last glacial period ended about 10,000 years ago. Earth is currently in an interglacial period of the Quaternary, called the Holocene.
Homo erectus georgicus, which lived roughly 1.8 million years ago in Georgia, is the earliest hominin to have been discovered in Europe. Other hominin remains, dating back roughly 1 million years, have been discovered in Atapuerca, Spain. Neanderthal man (named after the Neandertal valley in Germany) appeared in Europe 150,000 years ago (115,000 years ago it is found already in the territory of present-day Poland) and disappeared from the fossil record about 28,000 years ago, with their final refuge being present-day Portugal. The Neanderthals were supplanted by modern humans (Cro-Magnons), who appeared in Europe around 43,000 to 40,000 years ago.Homo sapiens arrived in Europe around 54,000 years ago, some 10,000 years earlier than previously thought. The earliest sites in Europe dated 48,000 years ago are Riparo Mochi (Italy), Geissenklösterle (Germany) and Isturitz (France).
The European Neolithic period—marked by the cultivation of crops and the raising of livestock, increased numbers of settlements and the widespread use of pottery—began around 7000 BCE in Greece and the Balkans, probably influenced by earlier farming practices in Anatolia and the Near East. It spread from the Balkans along the valleys of the Danube and the Rhine (Linear Pottery culture), and along the Mediterranean coast (Cardial culture). Between 4500 and 3000 BCE, these central European neolithic cultures developed further to the west and the north, transmitting newly acquired skills in producing copper artifacts. In Western Europe the Neolithic period was characterised not by large agricultural settlements but by field monuments, such as causewayed enclosures, burial mounds and megalithic tombs. The Corded Ware cultural horizon flourished at the transition from the Neolithic to the Chalcolithic. During this period giant megalithic monuments, such as the Megalithic Temples of Malta and Stonehenge, were constructed throughout Western and Southern Europe.
The European Bronze Age began c. 3200 BCE in Greece with the Minoan civilisation on Crete, the first advanced civilisation in Europe. The Minoans were followed by the Myceneans, who collapsed suddenly around 1200 BCE, ushering the European Iron Age. Iron Age colonisation by the Greeks and Phoenicians gave rise to early Mediterranean cities. Early Iron Age Italy and Greece from around the 8th century BCE gradually gave rise to historical Classical antiquity, whose beginning is sometimes dated to 776 BCE, the year of the first Olympic Games.


The question of defining a precise eastern boundary of Europe arises in the Early Modern period, as the eastern extension of Muscovy began to include North Asia. Throughout the Middle Ages and into the 18th century, the traditional division of the landmass of Eurasia into two continents, Europe and Asia, followed Ptolemy, with the boundary following the Turkish Straits, the Black Sea, the Kerch Strait, the Sea of Azov and the Don (ancient Tanais). But maps produced during the 16th to 18th centuries tended to differ in how to continue the boundary beyond the Don bend at Kalach-na-Donu (where it is closest to the Volga, now joined with it by the Volga–Don Canal), into territory not described in any detail by the ancient geographers.
Around 1715, Herman Moll produced a map showing the northern part of the Ob River and the Irtysh River, a major tributary of the Ob, as components of a series of partly-joined waterways taking the boundary between Europe and Asia from the Turkish Straits, and the Don River all the way to the Arctic Ocean. In 1721, he produced a more up to date map that was easier to read. However, his proposal to adhere to major rivers as the line of demarcation was never taken up by other geographers who were beginning to move away from the idea of water boundaries as the only legitimate divides between Europe and Asia.
Four years later, in 1725, Philip Johan von Strahlenberg was the first to depart from the classical Don boundary.  He drew a new line along the Volga, following the Volga north until the Samara Bend, along Obshchy Syrt (the drainage divide between the Volga and Ural Rivers), then north and east along the latter waterway to its source in the Ural Mountains. At this point he proposed that mountain ranges could be included as boundaries between continents as alternatives to nearby waterways. Accordingly, he drew the new boundary north along Ural Mountains rather than the nearby and parallel running Ob and Irtysh rivers. This was endorsed by the Russian Empire and introduced the convention that would eventually become commonly accepted. However, this did not come without criticism. Voltaire, writing in 1760 about Peter the Great's efforts to make Russia more European, ignored the whole boundary question with his claim that neither Russia, Scandinavia, northern Germany, nor Poland were fully part of Europe.  Since then, many modern analytical geographers like Halford Mackinder have declared that they see little validity in the Ural Mountains as a boundary between continents.
The mapmakers continued to differ on the boundary between the lower Don and Samara well into the 19th century. The 1745 atlas published by the Russian Academy of Sciences has the boundary follow the Don beyond Kalach as far as Serafimovich before cutting north towards Arkhangelsk, while other 18th- to 19th-century mapmakers such as John Cary followed Strahlenberg's prescription. To the south, the Kuma–Manych Depression was identified circa 1773 by a German naturalist, Peter Simon Pallas, as a valley that once connected the Black Sea and the Caspian Sea, and subsequently was proposed as a natural boundary between continents.
By the mid-19th century, there were three main conventions, one following the Don, the Volga–Don Canal and the Volga, the other following the Kuma–Manych Depression to the Caspian and then the Ural River, and the third abandoning the Don altogether, following the Greater Caucasus watershed to the Caspian. The question was still treated as a "controversy" in geographical literature of the 1860s, with Douglas Freshfield advocating the Caucasus crest boundary as the "best possible", citing support from various "modern geographers".
In Russia and the Soviet Union, the boundary along the Kuma–Manych Depression was the most commonly used as early as 1906. In 1958, the Soviet Geographical Society formally recommended that the boundary between the Europe and Asia be drawn in textbooks from Baydaratskaya Bay, on the Kara Sea, along the eastern foot of Ural Mountains, then following the Ural River until the Mugodzhar Hills, and then the Emba River; and Kuma–Manych Depression, thus placing the Caucasus entirely in Asia and the Urals entirely in Europe. However, most geographers in the Soviet Union favoured the boundary along the Caucasus crest, and this became the common convention in the later 20th century, although the Kuma–Manych boundary remained in use in some 20th-century maps.
Some view separation of Eurasia into Asia and Europe as a residue of Eurocentrism: "In physical, cultural and historical diversity, China and India are comparable to the entire European landmass, not to a single European country. [...]."


In classical Greek mythology, Europa (Ancient Greek: Εὐρώπη, Eurṓpē) was a Phoenician princess. One view is that her name derives from the Ancient Greek elements εὐρύς (eurús) 'wide, broad', and ὤψ (ōps, gen. ὠπός, ōpós) 'eye, face, countenance', hence their composite Eurṓpē would mean 'wide-gazing' or 'broad of aspect'. Broad has been an epithet of Earth herself in the reconstructed Proto-Indo-European religion and the poetry devoted to it. An alternative view is that of Robert Beekes, who has argued in favour of a Pre-Indo-European origin for the name, explaining that a derivation from eurus would yield a different toponym than Europa. Beekes has located toponyms related to that of Europa in the territory of ancient Greece, and localities such as that of Europos in ancient Macedonia.
There have been attempts to connect Eurṓpē to a Semitic term for west, this being either Akkadian erebu meaning 'to go down, set' (said of the sun) or Phoenician 'ereb 'evening, west', which is at the origin of Arabic maghreb and Hebrew ma'arav. Martin Litchfield West stated that "phonologically, the match between Europa's name and any form of the Semitic word is very poor", while Beekes considers a connection to Semitic languages improbable.
Most major world languages use words derived from Eurṓpē or Europa to refer to the continent. Chinese, for example, uses the word Ōuzhōu (歐洲/欧洲), which is an abbreviation of the transliterated name Ōuluóbā zhōu (歐羅巴洲) (zhōu means "continent"); a similar Chinese-derived term Ōshū (欧州) is also sometimes used in Japanese such as in the Japanese name of the European Union, Ōshū Rengō (欧州連合), despite the katakana Yōroppa (ヨーロッパ) being more commonly used. In some Turkic languages, the originally Persian name Frangistan ('land of the Franks') is used casually in referring to much of Europe, besides official names such as Avrupa or Evropa.


During the decline of the Roman Empire, Europe entered a long period of change arising from what historians call the "Age of Migrations". There were numerous invasions and migrations amongst the Ostrogoths, Visigoths, Goths, Vandals, Huns, Franks, Angles, Saxons, Slavs, Avars, Bulgars and, later on, the Vikings, Pechenegs, Cumans and Magyars. Renaissance thinkers such as Petrarch would later refer to this as the "Dark Ages".
Isolated monastic communities were the only places to safeguard and compile written knowledge accumulated previously; apart from this very few written records survive and much literature, philosophy, mathematics and other thinking from the classical period disappeared from Western Europe, though they were preserved in the east, in the Byzantine Empire.
While the Roman empire in the west continued to decline, Roman traditions and the Roman state remained strong in the predominantly Greek-speaking Eastern Roman Empire, also known as the Byzantine Empire. During most of its existence, the Byzantine Empire was the most powerful economic, cultural and military force in Europe. Emperor Justinian I presided over Constantinople's first golden age: he established a legal code that forms the basis of many modern legal systems, funded the construction of the Hagia Sophia and brought the Christian church under state control.
From the 7th century onwards, as the Byzantines and neighbouring Sasanid Persians were severely weakened due to the protracted, centuries-lasting and frequent Byzantine–Sasanian wars, the Muslim Arabs began to make inroads into historically Roman territory, taking the Levant and North Africa and making inroads into Asia Minor. In the mid-7th century, following the Muslim conquest of Persia, Islam penetrated into the Caucasus region. Over the next centuries Muslim forces took Cyprus, Malta, Crete, Sicily and parts of southern Italy. Between 711 and 720, most of the lands of the Visigothic Kingdom of Iberia was brought under Muslim rule—save for small areas in the north-west (Asturias) and largely Basque regions in the Pyrenees. This territory, under the Arabic name Al-Andalus, became part of the expanding Umayyad Caliphate. The unsuccessful second siege of Constantinople (717) weakened the Umayyad dynasty and reduced their prestige. The Umayyads were then defeated by the Frankish leader Charles Martel at the Battle of Poitiers in 732, which ended their northward advance. In the remote regions of north-western Iberia and the middle Pyrenees the power of the Muslims in the south was scarcely felt. It was here that the foundations of the Christian kingdoms of Asturias, Leon and Galicia were laid and from where the reconquest of the Iberian Peninsula would start. However, no coordinated attempt would be made to drive the Moors out. The Christian kingdoms were mainly focussed on their own internal power struggles. As a result, the Reconquista took the greater part of eight hundred years, in which period a long list of Alfonsos, Sanchos, Ordoños, Ramiros, Fernandos and Bermudos would be fighting their Christian rivals as much as the Muslim invaders.
During the Dark Ages, the Western Roman Empire fell under the control of various tribes. The Germanic and Slav tribes established their domains over Western and Eastern Europe, respectively. Eventually the Frankish tribes were united under Clovis I. Charlemagne, a Frankish king of the Carolingian dynasty who had conquered most of Western Europe, was anointed "Holy Roman Emperor" by the Pope in 800. This led in 962 to the founding of the Holy Roman Empire, which eventually became centred in the German principalities of central Europe.
East Central Europe saw the creation of the first Slavic states and the adoption of Christianity (c. 1000 CE). The powerful West Slavic state of Great Moravia spread its territory all the way south to the Balkans, reaching its largest territorial extent under Svatopluk I and causing a series of armed conflicts with East Francia. Further south, the first South Slavic states emerged in the late 7th and 8th century and adopted Christianity: the First Bulgarian Empire, the Serbian Principality (later Kingdom and Empire) and the Duchy of Croatia (later Kingdom of Croatia). To the East, the Kievan Rus expanded from its capital in Kyiv to become the largest state in Europe by the 10th century. In 988, Vladimir the Great adopted Orthodox Christianity as the religion of state. Further East, Volga Bulgaria became an Islamic state in the 10th century, but was eventually absorbed into Russia several centuries later.


The first recorded usage of Eurṓpē as a geographic term is in the Homeric Hymn to Delian Apollo, in reference to the western shore of the Aegean Sea. As a name for a part of the known world, it is first used in the 6th century BCE by Anaximander and Hecataeus. Anaximander placed the boundary between Asia and Europe along the Phasis River (the modern Rioni River on the territory of Georgia) in the Caucasus, a convention still followed by Herodotus in the 5th century BCE. Herodotus mentioned that the world had been divided by unknown persons into three parts, Europe, Asia and Libya (Africa), with the Nile and the Phasis forming their boundaries—though he also states that some considered the River Don, rather than the Phasis, as the boundary between Europe and Asia. Europe's eastern frontier was defined in the 1st century by geographer Strabo at the River Don. The Book of Jubilees described the continents as the lands given by Noah to his three sons; Europe was defined as stretching from the Pillars of Hercules at the Strait of Gibraltar, separating it from Northwest Africa, to the Don, separating it from Asia.
The convention received by the Middle Ages and surviving into modern usage is that of the Roman era used by Roman-era authors such as Posidonius, Strabo and Ptolemy, who took the Tanais (the modern Don River) as the boundary.
The Roman Empire did not attach a strong identity to the concept of continental divisions. However, following the fall of the Western Roman Empire, the culture that developed in its place, linked to Latin and the Catholic church, began to associate itself with the concept of "Europe". The term "Europe" is first used for a cultural sphere in the Carolingian Renaissance of the 9th century. From that time, the term designated the sphere of influence of the Western Church, as opposed to both the Eastern Orthodox churches and to the Islamic world.
A cultural definition of Europe as the lands of Latin Christendom coalesced in the 8th century, signifying the new cultural condominium created through the confluence of Germanic traditions and Christian-Latin culture, defined partly in contrast with Byzantium and Islam, and limited to northern Iberia, the British Isles, France, Christianised western Germany, the Alpine regions and northern and central Italy. The concept is one of the lasting legacies of the Carolingian Renaissance: Europa often figures in the letters of Charlemagne's court scholar, Alcuin. The transition of Europe to being a cultural term as well as a geographic one led to the borders of Europe being affected by cultural considerations in the East, especially relating to areas under Byzantine, Ottoman, and Russian influence. Such questions were affected by the positive connotations associated with the term Europe by its users. Such cultural considerations were not applied to the Americas, despite their conquest and settlement by European states. Instead, the concept of "Western civilization" emerged as a way of grouping together Europe and these colonies.

December is the twelfth and the final month of the year in the Julian and Gregorian calendars. It is also the last of seven months to have a length of 31 days.
December got its name from the Latin word decem (meaning ten) because it was originally the tenth month of the year in the calendar of Romulus c. 750 BC which began in March. The winter days following December were not included as part of any month. Later, the months of January and February were created out of the monthless period and added to the beginning of the calendar, but December retained its name.
In Ancient Rome, as one of the four Agonalia, this day in honour of Sol Indiges was held on December 11, as was Septimontium. Dies natalis (birthday) was held at the temple of Tellus on December 13, Consualia was held on December 15, Saturnalia was held December 17–23, Opiconsivia was held on December 19, Divalia was held on December 21, Larentalia was held on December 23, and the dies natalis of Sol Invictus was held on December 25. These dates do not correspond to the modern Gregorian calendar.
The Anglo-Saxons referred to December–January as Ġēolamonaþ (modern English: "Yule month"). The French Republican Calendar contained December within the months of Frimaire and Nivôse.


December's birth flower is the narcissus.

1842 (MDCCCXLII) was a common year starting on Saturday of the Gregorian calendar and a common year starting on Thursday of the Julian calendar, the 1842nd year of the Common Era (CE) and Anno Domini (AD) designations, the 842nd  year of the 2nd millennium, the 42nd  year of the 19th century, and the  3rd   year of the 1840s decade. As of the start of 1842, the Gregorian calendar was 12 days ahead of the Julian calendar, which remained in localized use until 1923.


Rome, a settlement around a ford on the river Tiber in central Italy conventionally founded in 753 BC, was ruled for a period of 244 years by a monarchical system, initially with sovereigns of Latin and Sabine origin, later by Etruscan kings. The tradition handed down seven kings: Romulus, Numa Pompilius, Tullus Hostilius, Ancus Marcius, Tarquinius Priscus, Servius Tullius and Tarquinius Superbus. In 509 BC, the Romans expelled the last king from their city, favouring a government of the Senate and the People (SPQR) and establishing an oligarchic republic.
The Italian Peninsula, named Italia, was consolidated into a single entity during the Roman expansion and conquest of new lands at the expense of the other Italic tribes, Etruscans, Celts, and Greeks. A permanent association with most of the local tribes and cities was formed, and Rome began the conquest of Western Europe, Northern Africa and the Middle East. In the wake of Julius Caesar's rise and death in the first century BC, Rome grew over the course of centuries into a massive empire stretching from Britain to the borders of Persia, and engulfing the whole Mediterranean basin, in which Greek and Roman and many other cultures merged into a unique civilisation. The long and triumphant reign of the first emperor, Augustus, began a golden age of peace and prosperity. Roman Italy remained the metropole of the empire, and as the homeland of the Romans and the territory of the capital, maintained a special status which made it Domina Provinciarum ("ruler of the provinces", the latter being all the remaining territories outside Italy). More than two centuries of stability followed, during which Italy was referred to as the Rectrix Mundi ("governor of the world") and Omnium Terrarum Parens ("parent of all lands").
The Roman Empire was among the most powerful economic, cultural, political and military forces in the world of its time, and it was one of the largest empires in world history. At its height under Trajan, it covered 5 million square kilometres. The Roman legacy has deeply influenced Western civilisation, shaping most of the modern world; among the many legacies of Roman dominance are the widespread use of the Romance languages derived from Latin, the numerical system, the modern Western alphabet and calendar, and the emergence of Christianity as a major world religion. The Indo-Roman trade relations, beginning around the 1st century BCE, testify to extensive Roman trade in far away regions; many reminders of the commercial trade between the Indian subcontinent and Italy have been found, such as the ivory statuette Pompeii Lakshmi from the ruins of Pompeii.
In a slow decline since the third century AD, the Empire split in two in 395 AD. The Western Empire, under the pressure of the barbarian invasions, eventually dissolved in 476 AD when its last emperor, Romulus Augustulus, was deposed by the Germanic chief Odoacer. The Eastern half of the Empire survived for another thousand years.


Italy was the birthplace and heart of the Renaissance during the 1400s and 1500s. The Italian Renaissance marked the transition from the medieval period to the modern age as Europe recovered, economically and culturally, from the crises of the Late Middle Ages and entered the Early Modern Period. The Italian polities were now regional states effectively ruled by Princes, de facto monarchs in control of trade and administration, and their courts became major centres of the Arts and Sciences. The Italian princedoms represented a first form of modern states as opposed to feudal monarchies and multinational empires. The princedoms were led by political dynasties and merchant families such as the Medici in Florence, the Visconti and Sforza in the Duchy of Milan, the Doria in the Republic of Genoa, the Loredan, Mocenigo and Barbarigo in the Republic of Venice, the Este in Ferrara, and the Gonzaga in Mantua. The Renaissance was therefore a result of the wealth accumulated by Italian merchant cities combined with the patronage of its dominant families. Italian Renaissance exercised a dominant influence on subsequent European painting and sculpture for centuries afterwards, with artists such as Leonardo da Vinci, Brunelleschi, Botticelli, Michelangelo, Raphael, Giotto, Donatello, and Titian, and architects such as Filippo Brunelleschi, Leon Battista Alberti, Andrea Palladio, and Donato Bramante.
Following the conclusion of the western schism in favour of Rome at the Council of Constance (1415–1417), the new Pope Martin V returned to the Papal States after a three years-long journey that touched many Italian cities and restored Italy as the sole centre of Western Christianity. During the course of this voyage, the Medici Bank was made the official credit institution of the Papacy, and several significant ties were established between the Church and the new political dynasties of the peninsula. The Popes' status as elective monarchs turned the conclaves and consistories of the Renaissance into political battles between the courts of Italy for primacy in the peninsula and access to the immense resources of the Catholic Church. In 1439, Pope Eugenius IV and the Byzantine Emperor John VIII Palaiologos signed a reconciliation agreement between the Catholic Church and the Orthodox Church at the Council of Florence hosted by Cosimo the old de Medici. In 1453, Italian forces under Giovanni Giustiniani were sent by Pope Nicholas V to defend the Walls of Constantinople but the decisive battle was lost to the more advanced Turkish army equipped with cannons, and Byzantium fell to Sultan Mehmed II.
The fall of Constantinople led to the migration of Greek scholars and texts to Italy, fueling the rediscovery of Greco-Roman Humanism. Humanist rulers such as Federico da Montefeltro and Pope Pius II worked to establish ideal cities where man is the measure of all things, and therefore founded Urbino and Pienza respectively. Pico della Mirandola wrote the Oration on the Dignity of Man, considered the manifesto of Renaissance Humanism, in which he stressed the importance of free will in human beings. The humanist historian Leonardo Bruni was the first to divide human history in three periods: Antiquity, Middle Ages and Modernity. The second consequence of the Fall of Constantinople was the beginning of the Age of Discovery.
Italian explorers and navigators from the dominant maritime republics, eager to find an alternative route to the Indies in order to bypass the Ottoman Empire, offered their services to monarchs of Atlantic countries and played a key role in ushering the Age of Discovery and the European colonization of the Americas. The most notable among them were: Christopher Columbus, colonizer in the name of Spain, who is credited with discovering the New World and the opening of the Americas for conquest and settlement by Europeans; John Cabot, sailing for England, who was the first European to set foot in "New Found Land" and explore parts of the North American continent in 1497; Amerigo Vespucci, sailing for Portugal, who first demonstrated in about 1501 that the New World (in particular Brazil) was not Asia as initially conjectured, but a fourth continent previously unknown to people of the Old World (America is named after him); and Giovanni da Verrazzano, at the service of France, renowned as the first European to explore the Atlantic coast of North America between Florida and New Brunswick in 1524.
Following the fall of Constantinople, the wars in Lombardy came to an end and a defensive alliance known as Italic League was formed between Venice, Naples, Florence, Milan, and the Papacy. Lorenzo the Magnificent de Medici was the greatest Florentine patron of the Renaissance and supporter of the Italic League. He notably avoided the collapse of the League in the aftermath of the Pazzi Conspiracy and during the aborted invasion of Italy by the Turks. However, the military campaign of Charles VIII of France in Italy caused the end of the Italic League and initiated the Italian Wars between the Valois and the Habsburgs. During the High Renaissance of the 1500s, Italy was therefore both the main European battleground and the cultural-economic centre of the continent. Popes such as Julius II (1503–1513) fought for the control of Italy against foreign monarchs, others such as Paul III (1534–1549) preferred to mediate between the European powers in order to secure peace in Italy. In the middle of this conflict, the Medici popes Leo X (1513–1521) and Clement VII (1523–1534) opposed the Protestant reformation and advanced the interests of their family. In 1559, at the end of the French invasions of Italy and of the Italian wars, the many states of northern Italy remained part of the Holy Roman Empire, indirectly subject to the Austrian Habsburgs, while all of Southern Italy (Naples, Sicily, Sardinia) and Milan were under Spanish Habsburg rule.
The Papacy remained a powerful force and launched the Counter-reformation. Key events of the period include: the Council of Trent (1545–1563); the excommunication of Elizabeth I (1570) and the Battle of Lepanto (1571), both occurring during the pontificate of Pius V; the construction of the Gregorian observatory, the adoption of the Gregorian calendar, and the Jesuit China mission of Matteo Ricci under Pope Gregory XIII; the French Wars of Religion; the Long Turkish War and the execution of Giordano Bruno in 1600, under Pope Clement VIII; the birth of the Lyncean Academy of the Papal States, of which the main figure was Galileo Galilei (later put on trial); the final phases of the Thirty Years' War (1618–1648) during the pontificates of Urban VIII and Innocent X; and the formation of the last Holy League by Innocent XI during the Great Turkish War.
The Italian economy declined during the 1600s and 1700s, as the peninsula was excluded from the rising Atlantic slave trade. Following the European wars of succession of the 18th century, the south passed to a cadet branch of the Spanish Bourbons and the North fell under the influence of the Habsburg-Lorraine of Austria. During the Coalition Wars, northern-central Italy was reorganised by Napoleon in a number of Sister Republics of France and later as a Kingdom of Italy in personal union with the French Empire. The southern half of the peninsula was administered by Joachim Murat, Napoleon's brother-in-law, who was crowned as King of Naples. The 1814 Congress of Vienna restored the situation of the late 18th century, but the ideals of the French Revolution could not be eradicated, and soon re-surfaced during the political upheavals that characterised the first part of the 19th century.
During the Napoleonic era, in 1797, the first official adoption of the Italian tricolour as a national flag by a sovereign Italian state, the Cispadane Republic, a Napoleonic sister republic of Revolutionary France, took place, on the basis of the events following the French Revolution (1789–1799) which, among its ideals, advocated the national self-determination. This event is celebrated by the Tricolour Day. The Italian national colours appeared for the first time on a tricolour cockade in 1789, anticipating by seven years the first green, white and red Italian military war flag, which was adopted by the Lombard Legion in 1796.


The birth of the Kingdom of Italy was the result of efforts by Italian nationalists and monarchists loyal to the House of Savoy to establish a united kingdom encompassing the entire Italian Peninsula. Following the Congress of Vienna in 1815, the political and social Italian unification movement, or Risorgimento, emerged to unite Italy consolidating the different states of the peninsula and liberate it from foreign control. A prominent radical figure was the patriotic journalist Giuseppe Mazzini, member of the secret revolutionary society Carbonari and founder of the influential political movement Young Italy in the early 1830s, who favoured a unitary republic and advocated a broad nationalist movement. His prolific output of propaganda helped the unification movement stay active.
In this context, in 1847, the first public performance of the song Il Canto degli Italiani, the Italian national anthem since 1946, took place. Il Canto degli Italiani, written by Goffredo Mameli set to music by Michele Novaro, is also known as the Inno di Mameli, after the author of the lyrics, or Fratelli d'Italia, from its opening line.
The most famous member of Young Italy was the revolutionary and general Giuseppe Garibaldi, renowned for his extremely loyal followers, who led the Italian republican drive for unification in Southern Italy. However, the Northern Italy monarchy of the House of Savoy in the Kingdom of Sardinia, whose government was led by Camillo Benso, Count of Cavour, also had ambitions of establishing a united Italian state. In the context of the 1848 liberal revolutions that swept through Europe, an unsuccessful first war of independence was declared on Austria. In 1855, the Kingdom of Sardinia became an ally of Britain and France in the Crimean War, giving Cavour's diplomacy legitimacy in the eyes of the great powers. The Kingdom of Sardinia again attacked the Austrian Empire in the Second Italian War of Independence of 1859, with the aid of France, resulting in liberating Lombardy. On the basis of the Plombières Agreement, the Kingdom of Sardinia ceded Savoy and Nice to France, an event that caused the Niçard exodus, that was the emigration of a quarter of the Niçard Italians to Italy.
In 1860–1861, Garibaldi led the drive for unification in Naples and Sicily (the Expedition of the Thousand), while the House of Savoy troops occupied the central territories of the Italian peninsula, except Rome and part of Papal States. Teano was the site of the famous meeting of 26 October 1860 between Giuseppe Garibaldi and Victor Emmanuel II, last King of Sardinia, in which Garibaldi shook Victor Emanuel's hand and hailed him as King of Italy; thus, Garibaldi sacrificed republican hopes for the sake of Italian unity under a monarchy. Cavour agreed to include Garibaldi's Southern Italy allowing it to join the union with the Kingdom of Sardinia in 1860. This allowed the Sardinian government to declare a united Italian kingdom on 17 March 1861. Victor Emmanuel II then became the first king of a united Italy, and the capital was moved from Turin to Florence.
In 1866, Victor Emmanuel II allied with Prussia during the Austro-Prussian War, waging the Third Italian War of Independence which allowed Italy to annexe Venetia. Finally, in 1870, as France abandoned its garrisons in Rome during the disastrous Franco-Prussian War to keep the large Prussian Army at bay, the Italians rushed to fill the power gap by taking over the Papal States. Italian unification was completed and shortly afterwards Italy's capital was moved to Rome. Victor Emmanuel, Garibaldi, Cavour, and Mazzini have been referred as Italy's Four Fathers of the Fatherland.


Hypotheses for the etymology of the name "Italia" are numerous. One is that it was borrowed via Ancient Greek from the Oscan Víteliú 'land of calves' (cf. Lat vitulus "calf", Umb vitlo "calf"). Ancient Greek historian Dionysius of Halicarnassus states this account together with the legend that Italy was named after Italus, mentioned also by Aristotle and Thucydides.
According to Antiochus of Syracuse, the term Italy was used by the ancient Greeks to initially refer only to the southern portion of the Bruttium peninsula corresponding to the modern province of Reggio and part of the provinces of Catanzaro and Vibo Valentia in southern Italy. Nevertheless, by his time the larger concept of Oenotria and "Italy" had become synonymous, and the name also applied to most of Lucania as well. According to Strabo's Geographica, before the expansion of the Roman Republic, the name was used by ancient Greeks to indicate the land between the strait of Messina and the line connecting the gulf of Salerno and gulf of Taranto, corresponding roughly to the current region of Calabria. The ancient Greeks gradually came to apply the name "Italia" to a larger region In addition to the "Greek Italy" in the south, historians have suggested the existence of an "Etruscan Italy" covering variable areas of central Italy.
The borders of Roman Italy, Italia, are better established. Cato's Origines, the first work of history composed in Latin, described Italy as the entire peninsula south of the Alps. According to Cato and several Roman authors, the Alps formed the "walls of Italy". In 264 BC, Roman Italy extended from the Arno and Rubicon rivers of the centre-north to the entire south. The northern area of Cisalpine Gaul was occupied by Rome in the 220s BC and became considered geographically and de facto part of Italy, but remained politically and de jure separated. It was legally merged into the administrative unit of Italy in 42 BC by the triumvir Octavian as a ratification of Caesar's unpublished acts (Acta Caesaris). The islands of Sardinia, Corsica, Sicily and Malta were added to Italy by Diocletian in 292 AD., coinciding with the whole Italian geographical region. All its inhabitants were considered Italic and Roman.
The Latin term Italicus was used to describe "a man of Italy" as opposed to a provincial. For example, Pliny the Elder notably wrote in a letter Italicus es an provincialis? meaning "are you an Italian or a provincial?".
The adjective italianus, from which are derived the Italian (and also French and English) name of the Italians, is medieval and was used alternatively with Italicus during the early modern period.
After the fall of the Western Roman Empire, which was caused by the invasion of the Ostrogoths, the Kingdom of Italy was created. After the Lombard invasions, "Italia" was retained as the name for their kingdom, and for its successor kingdom within the Holy Roman Empire, which nominally lasted until 1806, although it had de facto disintegrated due to factional politics pitting the empire against the ascendant city republics in the 13th century.


After the fall of the Western Roman Empire, Italy fell under the power of Odoacer's kingdom, and, later, was seized by the Ostrogoths, followed in the 6th century by a brief reconquest under Byzantine Emperor Justinian. The invasion of another Germanic tribe, the Lombards, late in the same century, reduced the Byzantine presence to the rump realm of the Exarchate of Ravenna and started the end of political unity of the peninsula for the next 1,300 years. Invasions of the peninsula caused a chaotic succession of barbarian kingdoms and the so-called "dark ages". The Lombard kingdom was subsequently absorbed into the Frankish Empire by Charlemagne in the late 8th century. The Franks also helped the formation of the Papal States in central Italy. Until the 13th century, Italian politics was dominated by the relations between the Holy Roman Emperors and the Papacy, with most of the Italian city-states siding with the former (Ghibellines) or with the latter (Guelphs) for momentary convenience.
The Germanic Emperor and the Roman Pontiff became the universal powers of medieval Europe. However, the conflict over the investiture controversy (a conflict between two radically different views of whether secular authorities such as kings, counts, or dukes, had any legitimate role in appointments to ecclesiastical offices) and the clash between Guelphs and Ghibellines led to the end of the Imperial-feudal system in the north of Italy where city-states gained independence. It was during this chaotic era that Italian towns saw the rise of a peculiar institution, the medieval commune. Given the power vacuum caused by extreme territorial fragmentation and the struggle between the Empire and the Holy See, local communities sought autonomous ways to maintain law and order. The investiture controversy was finally resolved by the Concordat of Worms. In 1176 a league of city-states, the Lombard League, defeated the German emperor Frederick Barbarossa at the Battle of Legnano, thus ensuring effective independence for most of northern and central Italian cities.
Italian city-states such as Milan, Florence and Venice played a crucial innovative role in financial development, devising the main instruments and practices of banking and the emergence of new forms of social and economic organization. In coastal and southern areas, the maritime republics grew to eventually dominate the Mediterranean and monopolise trade routes to the Orient. They were independent thalassocratic city-states, though most of them originated from territories once belonging to the Byzantine Empire. All these cities during the time of their independence had similar systems of government in which the merchant class had considerable power. Although in practice these were oligarchical, and bore little resemblance to a modern democracy, the relative political freedom they afforded was conducive to academic and artistic advancement. The four best known maritime republics were Venice, Genoa, Pisa and Amalfi; the others were Ancona, Gaeta, Noli, and Ragusa. Each of the maritime republics had dominion over different overseas lands, including many Mediterranean islands (especially Sardinia and Corsica), lands on the Adriatic, Aegean, and Black Sea (Crimea), and commercial colonies in the Near East and in North Africa. Venice maintained enormous tracts of land in Greece, Cyprus, Istria, and Dalmatia until as late as the mid-17th century.
Venice and Genoa were Europe's main gateways to trade with the East, and producers of fine glass, while Florence was a capital of silk, wool, banking, and jewellery. The wealth such business brought to Italy meant that large public and private artistic projects could be commissioned. The republics were heavily involved in the Crusades, providing support and transport, but most especially taking advantage of the political and trading opportunities resulting from these wars. Italy first felt the huge economic changes in Europe which led to the commercial revolution: the Republic of Venice was able to defeat the Byzantine Empire and finance the voyages of Marco Polo to Asia; the first universities were formed in Italian cities, and scholars such as Thomas Aquinas obtained international fame; Frederick I of Sicily made Italy the political-cultural centre of a reign that temporarily included the Holy Roman Empire and the Kingdom of Jerusalem; capitalism and banking families emerged in Florence, where Dante and Giotto were active around 1300.
In the south, Sicily had become an Islamic emirate in the 9th century, thriving until the Italo-Normans conquered it in the late 11th century together with most of the Lombard and Byzantine principalities of southern Italy. Through a complex series of events, southern Italy developed as a unified kingdom, first under the House of Hohenstaufen, then under the Capetian House of Anjou and, from the 15th century, the House of Aragon. In Sardinia, the former Byzantine provinces became independent states known in Italian as Judicates, although some parts of the island fell under Genoese or Pisan rule until eventual Aragonese annexation in the 15th century. The Black Death pandemic of 1348 left its mark on Italy by killing perhaps one third of the population. However, the recovery from the plague led to a resurgence of cities, trade, and economy, which allowed the blossoming of Humanism and Renaissance that later spread to Europe.


The new Kingdom of Italy obtained Great Power status. The Constitutional Law of the Kingdom of Sardinia the Albertine Statute of 1848, was extended to the whole Kingdom of Italy in 1861, and provided for basic freedoms of the new State, but electoral laws excluded the non-propertied and uneducated classes from voting. The government of the new kingdom took place in a framework of parliamentary constitutional monarchy dominated by liberal forces. As Northern Italy quickly industrialised, the South and rural areas of the North remained underdeveloped and overpopulated, forcing millions of people to migrate abroad and fuelling a large and influential diaspora. The Italian Socialist Party constantly increased in strength, challenging the traditional liberal and conservative establishment.
Starting in the last two decades of the 19th century, Italy developed into a colonial power by forcing under its rule Eritrea and Somalia in East Africa, Tripolitania and Cyrenaica in North Africa (later unified in the colony of Libya) and the Dodecanese islands. From 2 November 1899 to 7 September 1901, Italy also participated as part of the Eight-Nation Alliance forces during the Boxer Rebellion in China; on 7 September 1901, a concession in Tientsin was ceded to the country, and on 7 June 1902, the concession was taken into Italian possession and administered by a consul. In 1913, male universal suffrage was adopted. The pre-war period dominated by Giovanni Giolitti, Prime Minister five times between 1892 and 1921, was characterised by the economic, industrial, and political-cultural modernization of Italian society.
Italy entered into the First World War in 1915 with the aim of completing national unity: for this reason, the Italian intervention in the First World War is also considered the Fourth Italian War of Independence, in a historiographical perspective that identifies in the latter the conclusion of the unification of Italy, whose military actions began during the revolutions of 1848 with the First Italian War of Independence.
Italy, nominally allied with the German Empire and the Empire of Austria-Hungary in the Triple Alliance, in 1915 joined the Allies into World War I with a promise of substantial territorial gains, that included western Inner Carniola, former Austrian Littoral, Dalmatia as well as parts of the Ottoman Empire. The country gave a fundamental contribution to the victory of the conflict as one of the "Big Four" top Allied powers. The war on the Italian Front was initially inconclusive, as the Italian army got stuck in a long attrition war in the Alps, making little progress and suffering heavy losses. However, the reorganization of the army and the conscription of the so-called '99 Boys (Ragazzi del '99, all males born in 1899 who were turning 18) led to more effective Italian victories in major battles, such as on Monte Grappa and in a series of battles on the Piave river. Eventually, in October 1918, the Italians launched a massive offensive, culminating in the victory of Vittorio Veneto. The Italian victory, which was announced by the Bollettino della Vittoria and the Bollettino della Vittoria Navale, marked the end of the war on the Italian Front, secured the dissolution of the Austro-Hungarian Empire and was chiefly instrumental in ending the First World War less than two weeks later. Italian armed forces were also involved in the African theatre, the Balkan theatre, the Middle Eastern theatre, and then took part in the Occupation of Constantinople.
During the war, more than 650,000 Italian soldiers and as many civilians died, and the kingdom went to the brink of bankruptcy. The Treaty of Saint-Germain-en-Laye (1919) and the Treaty of Rapallo (1920) allowed the annexation of Trentino Alto-Adige, Julian March, Istria, Kvarner as well as the Dalmatian city of Zara. The subsequent Treaty of Rome (1924) led to the annexation of the city of Fiume to Italy. Italy did not receive other territories promised by the Treaty of London (1915), so this outcome was denounced as a Mutilated victory. The rhetoric of Mutilated victory was adopted by Benito Mussolini and led to the rise of Italian fascism, becoming a key point in the propaganda of Fascist Italy. Historians regard Mutilated victory as a "political myth", used by fascists to fuel Italian imperialism and obscure the successes of liberal Italy in the aftermath of World War I. Italy also gained a permanent seat in the League of Nations's executive council.


The conventional application of pure perfume (parfum extrait) in Western cultures is behind the ears, at the nape of the neck, under the armpits and at the insides of wrists, elbows and knees, so that the pulse point will warm the perfume and release fragrance continuously. According to perfumer Sophia Grojsman behind the knees is the ideal point to apply perfume in order that the scent may rise. The modern perfume industry encourages the practice of layering fragrance so that it is released in different intensities depending upon the time of the day. Lightly scented products such as bath oil, shower gel, and body lotion are recommended for the morning; eau de toilette is suggested for the afternoon; and perfume applied to the pulse points for evening. Cologne fragrance is released rapidly, lasting around 2 hours. Eau de toilette lasts from 2 to 4 hours, while perfume may last up to six hours.
A variety of factors can influence how fragrance interacts with the wearer's own physiology and affect the perception of the fragrance. Diet is one factor, as eating spicy and fatty foods can increase the intensity of a fragrance.  The use of medications can also impact the character of a fragrance. The relative dryness of the wearer's skin is important, since dry skin will not hold fragrance as long as skin with more oil.


Southern Europe's flora is mainly characterized by Mediterranean forests, woodlands, and scrub, but also temperate broadleaf and mixed forests. The Mediterranean and Submediterranean climate regions in Europe are found in much of Southern Europe, mainly Portugal, Spain, Italy, Malta, Albania, Greece, Cyprus and all the mediterranean islands, but also in southeast France, the Balkan Mediterranean coast and part of Macedonia.


Southern Europe's most emblematic climate is the Mediterranean climate, influenced by the large subtropical semi-permanent centre of high atmospheric pressure found, not in the Mediterranean itself, but in the Atlantic Ocean, the Azores High. The Mediterranean climate covers Portugal, Spain, Italy, the southern coast of France, coastal Croatia, coastal Slovenia, southern Bosnia and Herzegovina, Montenegro, Albania, and Greece, as well as the Mediterranean islands. Those areas of Mediterranean climate present similar vegetations and landscapes throughout, including dry hills, small plains, pine forests and olive trees.
Cooler climates can be found in certain parts of Southern European countries, for example within the mountain ranges of Spain and Italy. Additionally, the north coast of Spain experiences a wetter Atlantic climate. In the highest regions of the Alps, which border Southern Europe, even ice cap climate can be found.
Some parts of Southern Europe have humid subtropical climates with warm and wet summers, unlike typical Mediterranean climates. This climate is mainly found in Italy and Croatia around the Adriatic Sea in cities such as Venice and Trieste, but also further north, near the Alpine foothills, in cities such as Como and Lugano.


Southern Europe is the southern region of Europe. It is also known as Mediterranean Europe, as its geography is essentially marked by the Mediterranean Sea. Definitions of Southern Europe include some or all of these countries and regions: Albania, Andorra, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Turkey (East Thrace), Gibraltar, Greece, Italy, Kosovo, Malta, Monaco, Montenegro, North Macedonia, Portugal, Romania, San Marino, Serbia, Slovenia, Southern France, Spain, and Vatican City (the Holy See).
Southern Europe is focused on the three peninsulas located in the extreme south of the European continent. These are the Iberian Peninsula, the Apennine Peninsula, and the Balkan Peninsula. These three peninsulas are separated from the rest of Europe by towering mountain ranges, respectively by the Pyrenees, the Alps and the Balkan Mountains. The location of these peninsulas in the heart of the Mediterranean Sea, as well as their mountainous reliefs, provide them with very different types of climates (mainly subtropical Mediterranean) from the rest of the continent. So, the Sirocco hot wind that originates in the heart of the Sahara blows over Italy, going up to the interior of the Alpine arc (Po Valley). The Alps prevent the Sirocco from spreading to the rest of Europe. And, conversely, the Alps and the Pyrenees protect the Italian and Iberian peninsulas from the rains and icy winds from the south of France such as the Mistral and the Tramontane. When the Mistral and the Tramontane are blowing, this provokes an "upwelling" phenomenon on the French coast. They push the surface waters out to sea and bring deeper, cooler waters up to the seaside. Consequently, the temperature of the waters of the French coasts are therefore very cool even in summer, and not representative of the rest of the Mediterranean.
This same kind of phenomenon takes place between the two slopes of the Balkan Mountain Range. These mountains have, moreover, been a serious handicap to population displacement, focusing southern Europe mainly on the Mediterranean world. The climate and cultures are therefore very specific.
Different methods can be used to define Southern Europe, including its political, economic, historical, and cultural attributes. Southern Europe can also be defined by its natural features — its geography, climate, and flora. Politically, nine of the Southern European countries form the EU Med Group. Southern Europe also loosely corresponds to the European part of the Mediterranean Basin.


The most widely spoken family of languages in Southern Europe are the Romance languages, the heirs of Latin, which have spread from the Italian peninsula, and are emblematic of Southwestern Europe. (See the Latin Arch.) By far the most common Romance languages in Southern Europe are Italian (spoken by over 50 million people in Italy, southern Switzerland, Malta, San Marino, and the Vatican) and Spanish, which is spoken by over 40 million people in Spain, Andorra and Gibraltar. Other common Romance languages include Portuguese (spoken in Portugal and Andorra), French (spoken in France, Monaco, and the Aosta Valley in Italy), Catalan (spoken in eastern Spain, Andorra, Southwestern France, and the Sardinian town of Alghero in Italy), Galician (spoken in northwestern Spain), Mirandese (spoken in northeast Portugal), and Occitan, which is spoken in the Val d'Aran in Catalonia, in the Occitan Valleys in Italy and in southern France.


Beginning roughly in the 12th century in Florence, and later spreading through Europe with the development of the printing press, a Renaissance of knowledge challenged traditional doctrines in science and theology, with the Arabic texts and thought bringing about rediscovery of classical Greek and Roman knowledge. The Catholic reconquest of Portugal and Spain led to a series of oceanic explorations resulting in the Age of Discovery that established direct links with Africa, the Americas, and Asia. During this period, Iberian forces engaged in a worldwide struggle with Islamic societies; the battlefronts in this Ibero-Islamic World War stretched from the Mediterranean into the Indian Ocean, finally involving the islands of Southeast Asia. Eventually this ecumenical conflict ended when new players—England, Holland and France—replaced Spain and Portugal as the main agents of European imperialism in the mid-17th century.
European overseas expansion led to the rise of colonial empires, producing the Columbian Exchange. The combination of resource inflows from the New World and the Industrial Revolution of Great Britain, allowed a new economy based on manufacturing instead of subsistence agriculture. The period between 1815 and 1871 saw a large number of revolutionary attempts and independence wars. Balkan nations began to regain independence from the Ottoman Empire. Italy unified into a nation state. The capture of Rome in 1870 ended the Papal temporal power.


The outbreak of World War I in 1914 was precipitated by the rise of nationalism in Southeastern Europe as the Great Powers took up sides. The Allies defeated the Central Powers in 1918. During the Paris Peace Conference the Big Four imposed their terms in a series of treaties, especially the Treaty of Versailles. The Nazi regime under Adolf Hitler came to power in 1933, and along with Mussolini's Italy sought to gain control of the continent by the Second World War.
Following the Allied victory in the Second World War, Europe was divided by the Iron Curtain. The countries in Southeastern Europe were dominated by the Soviet Union and became communist states. The major non-communist Southern European countries joined a US-led military alliance (NATO) and formed the European Economic Community amongst themselves. The countries in the Soviet sphere of influence joined the military alliance known as the Warsaw Pact and the economic bloc called Comecon. Yugoslavia was neutral. The common attribute of the eastern countries is that all of them have experiences about socialism, but nevertheless, the beginning of the 1990s was just roughly the same. For some of them becoming independent was the major challenge, while others needed to face with poverty and deep dictatorship also Economically, parallel with the political changes, and the democratic transition, – as a rule of law states – the previous command economies were transformed via the legislation into market economies, and set up or renewed the major macroeconomic factors: budgetary rules, national audit, national currency, central bank. Generally, they shortly encountered the following problems: high inflation, high unemployment, low economic growth and high government debt. By 2000 these economies were stabilized, and sooner or later between 2004 and 2013 some of them joined the European Union, and Slovenia introduced the euro.
Italy became a major industrialized country again, due to its post-war economic miracle. The European Union (EU) involved the division of powers, with taxation, health, and education handled by the nation states, while the EU had charge of market rules, competition, legal standards and environmentalism. The Soviet economic and political system collapsed, leading to the end of communism in the satellite countries in 1989, and the dissolution of the Soviet Union itself in 1991. European Union expanded to subsequently include many of the formerly communist European countries – Romania and Bulgaria (2007) and Croatia (2013).
The Gotthard, a major and direct transport axis between Northern and Southern Europe, was completed in 2016 with the Gotthard Base Tunnel. The Gotthard inscribes itself in a long history of transit across the Alps, which saw them progressively changing from an obstacle to a corridor between the North Sea and the Mediterranean Sea.

The outer layer, often edible, of most fruits is called the pericarp. Typically formed from the ovary, it surrounds the seeds; in some species, however, other structural tissues contribute to or form the edible portion. The pericarp may be described in three layers from outer to inner, i.e., the epicarp, mesocarp and endocarp.
Fruit that bears a prominent pointed terminal projection is said to be beaked.


Consistent with the three modes of fruit development plant scientists have classified fruits into three main groups: simple fruits, aggregate fruits, and multiple (or composite) fruits. The groupings reflect how the ovary and other flower organs are arranged and how the fruits develop, but they are not evolutionarily relevant as diverse plant taxa may be in the same group.
While the section of a fungus that produces spores is called a fruiting body, fungi are members of the fungi kingdom and not of the plant kingdom.


A fruit results from the fertilizing and maturing of one or more flowers. The gynoecium, which contains the stigma-style-ovary system, is centered in the flower-head, and it forms all or part of the fruit —(see graphic: 'the parts of a flower'). Inside the ovary(ies) are one or more ovules. Here begins a complex sequence called double fertilization: a  female gametophyte  produces an egg cell for the purpose of fertilization. (A female gametophyte is called a megagametophyte, and also called the embryo sac.) After double fertilization, the ovules will become seeds.
Ovules are fertilized in a process that starts with pollination, which is the movement of pollen from the stamens to the stigma-style-ovary system within the flower-head, (see graphic). After pollination, a pollen tube grows from the (deposited) pollen through the stigma down the style into the ovary to the ovule. Two sperm are transferred from the pollen to a megagametophyte. Within the megagametophyte one sperm unites with the egg, forming a zygote, while the second sperm enters the central cell forming the endosperm mother cell, which completes the double fertilization process. Later the zygote will give rise to the embryo of the seed, and the endosperm mother cell will give rise to endosperm, a nutritive tissue used by the embryo.
As the ovules develop into seeds, the ovary begins to ripen and the ovary wall, the pericarp, may become fleshy (as in berries or drupes), or it may form a hard outer covering (as in nuts). In some multiseeded fruits, the extent to which a fleshy structure develops is proportional to the number of fertilized ovules. The pericarp typically is differentiated into two or three distinct layers; these are called the exocarp (outer layer, also called epicarp), mesocarp (middle layer), and endocarp (inner layer) —(see image of apple-section).
In some fruits  the sepals, petals, stamens and/or the style of the flower fall away as the fleshy fruit ripens. However, for simple fruits derived from an inferior ovary —i.e., one that lies below the attachment of other floral parts, (see graphic re 'insertion point')— there are parts (including petals, sepals, and stamens) that fuse with the ovary and ripen with it. For such a case, when floral parts other than the ovary form a significant part of the fruit that develops, it is called an accessory fruit. Examples of accessory fruits include apple, rose hip, strawberry, pineapple; see below, and "Table of fleshy fruit examples".
Because several parts of the flower besides the ovary may contribute to the structure of a fruit, it is important to study flower structure to understand how a particular fruit forms. There are three general modes of fruit development:
Apocarpous fruits develop from a single flower (while having one or more separate, unfused, carpels); they are the simple fruits.
Syncarpous fruits develop from a single gynoecium (having two or more carpels fused together).
Multiple fruits form from many flowers —i.e., an inflorescence of flowers.


An aggregate fruit is also called an aggregation, or etaerio; it develops from a single flower that presents numerous simple pistils (see graphic of raspberry pistils). Each pistil contains one carpel; together they form a fruitlet. The ultimate (fruiting) development of the aggregation of pistils is called an aggregate fruit, etaerio fruit, or simply an etaerio.
Different types of aggregate fruits can produce different etaerios, such as achenes, drupelets, follicles, and berries.
For example, the Ranunculaceae species, including Clematis and Ranunculus, produces an etaerio of achenes;
Rubus species, including raspberry: an etaerio of drupelets;
Calotropis species: an etaerio of follicles fruit;
Annona species: an etaerio of berries.
Some other broadly recognized species and their etaerios (or aggregations) are:
Teasel; fruit is an aggregation of cypselas.
Tuliptree; fruit is an aggregation of samaras.
Magnolia and peony; fruit is an aggregation of follicles.
American sweet gum; fruit is an aggregation of capsules.
Sycamore; fruit is an aggregation of achenes.
The raspberry; its pistils are called drupelets because each pistil is like a small drupe attached to the receptacle. In some bramble fruits such as blackberry the receptacle, an accessory part, elongates and then develops as part of the fruit, making the blackberry an aggregate-accessory fruit. The strawberry is also an aggregate-accessory fruit, of which the seeds are contained in the achenes. Notably in all these examples, the fruit develops from a single flower, with numerous pistils.


In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering.
Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings.
In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also includes many structures that are not commonly called "fruits" in everyday language, such as nuts, bean pods, corn kernels, tomatoes, and wheat grains.


South America is thought to have been first inhabited by humans when people were crossing the Bering Land Bridge (now the Bering Strait) at least 15,000 years ago from the territory that is present-day Russia. They migrated south through North America, and eventually reached South America through the Isthmus of Panama.
The first evidence for the existence of the human race in South America dates back to about 9000 BC, when squashes, chili peppers and beans began to be cultivated for food in the highlands of the Amazon Basin. Pottery evidence further suggests that manioc, which remains a staple food today, was being cultivated as early as 2000 BC.
By 2000 BC, many agrarian communities had been settled throughout the Andes and the surrounding regions. Fishing became a widespread practice along the coast, helping establish fish as a primary source of food. Irrigation systems were also developed at this time, which aided in the rise of an agrarian society.
South American cultures began domesticating llamas, vicuñas, guanacos, and alpacas in the highlands of the Andes circa 3500 BC. Besides their use as sources of meat and wool, these animals were used for transportation of goods.


An isolated volcanic island on the South American Plate, Ascension Island is geologically a part of South America. Administered as a dependency of Saint Helena, Ascension and Tristan da Cunha, the island is geopolitically a part of Africa.
An uninhabited sub-Antarctic volcanic island located in the South Atlantic Ocean, Bouvet Island (administered by Norway) is geographically, geologically, biographically, and hydrologically associated with Antarctica, but the United Nations geoscheme has included the territory in South America instead.


The rise of plant growing and the subsequent appearance of permanent human settlements allowed for the multiple and overlapping beginnings of civilizations in South America.
One of the earliest known South American civilizations was at Norte Chico, on the central Peruvian coast. Though a pre-ceramic culture, the monumental architecture of Norte Chico is contemporaneous with the pyramids of Ancient Egypt. Norte Chico governing class established a trade network and developed agriculture then followed by Chavín by 900 BC, according to some estimates and archaeological finds. Artifacts were found at a site called Chavín de Huantar in modern Peru at an elevation of 3,177 meters (10,423 ft). Chavín civilization spanned 900 BC to 300 BC.
In the central coast of Peru, around the beginning of the 1st millennium AD, Moche (100 BC – 700 AD, at the northern coast of Peru), Paracas and Nazca (400 BC – 800 AD, Peru) cultures flourished with centralized states with permanent militia improving agriculture through irrigation and new styles of ceramic art. At the Altiplano, Tiahuanaco or Tiwanaku (100 BC – 1200 AD, Bolivia) managed a large commercial network based on religion.
Around the 7th century, both Tiahuanaco and Wari or Huari Empire (600–1200, Central and northern Peru) expanded its influence to all the Andean region, imposing the Huari urbanism and Tiahuanaco religious iconography.
The Muisca were the main indigenous civilization in what is now Colombia. They established the Muisca Confederation of many clans, or cacicazgos, that had a free trade network among themselves. They were goldsmiths and farmers.
Other important Pre-Columbian cultures include: the Cañaris (in south central Ecuador), Chimú Empire (1300–1470, Peruvian northern coast), Chachapoyas, and the Aymaran kingdoms (1000–1450, Western Bolivia and southern Peru).
Holding their capital at the great city of Cusco, the Inca civilization dominated the Andes region from 1438 to 1533. Known as Tawantin suyu, and "the land of the four regions," in Quechua, the Inca Empire was highly distinct and developed. Inca rule extended to nearly a hundred linguistic or ethnic communities, some nine to fourteen million people connected by a 25,000 kilometer road system. Cities were built with precise, unmatched stonework, constructed over many levels of mountain terrain. Terrace farming was a useful form of agriculture.
The Mapuche in Central and Southern Chile resisted the European and Chilean settlers, waging the Arauco War for more than 300 years.


South America is one of the most biodiverse continents on Earth. South America is home to many unique species of animals including the llama, anaconda, piranha, jaguar, vicuña, and tapir. The Amazon rainforests possess high biodiversity, containing a major proportion of Earth's species.


South America occupies the southern portion of the Americas. The continent is generally delimited on the northwest by the Darién watershed along the Colombia–Panama border, although some may consider the border instead to be the Panama Canal. Geopolitically and geographically, all of Panama – including the segment east of the Panama Canal in the isthmus – is typically included in North America alone and among the countries of Central America. Almost all of mainland South America sits on the South American Plate.
South America is home to the world's highest uninterrupted waterfall, Angel Falls in Venezuela; the highest single drop waterfall Kaieteur Falls in Guyana; the largest river by volume, the Amazon River; the longest mountain range, the Andes (whose highest mountain is Aconcagua at 6,962 m or 22,841 ft); the driest non-polar place on earth, the Atacama Desert; the wettest place on earth, López de Micay in Colombia; the largest rainforest, the Amazon rainforest; the highest capital city, La Paz, Bolivia; the highest commercially navigable lake in the world, Lake Titicaca; and, excluding research stations in Antarctica, the world's southernmost permanently inhabited community, Puerto Toro, Chile.
South America's major mineral resources are gold, silver, copper, iron ore, tin, and petroleum. These resources found in South America have brought high income to its countries especially in times of war or of rapid economic growth by industrialized countries elsewhere. However, the concentration in producing one major export commodity often has hindered the development of diversified economies. The fluctuation in the price of commodities in the international markets has led historically to major highs and lows in the economies of South American states, often causing extreme political instability. This is leading to efforts to diversify production to drive away from staying as economies dedicated to one major export.
Brazil is the largest country in South America, covering a little less than half of the continent's land area and encompassing around half of the continent's population. The remaining countries and territories are divided among four subregions: the Andean states, Caribbean South America, The Guianas, and the Southern Cone.


The distribution of the average temperatures in the region presents a constant regularity from the 30° of latitude south, when the isotherms tend, more and more, to be confused with the degrees of latitude.
In temperate latitudes, winters and summers are milder than in North America. This is because the most extensive part of the continent is in the equatorial zone (the region has more areas of equatorial plains than any other region.), therefore giving the Southern Cone more oceanic influence, which moderates year round temperatures.
The average annual temperatures in the Amazon basin oscillate around 27 °C (81 °F), with low thermal amplitudes and high rainfall indices. Between the Maracaibo Lake and the mouth of the Orinoco, predominates an equatorial climate of the type Congolese, that also includes parts of the Brazilian territory.
The east-central Brazilian plateau has a humid and warm tropical climate. The northern and eastern parts of the Argentine pampas have a humid subtropical climate with dry winters and humid summers of the Chinese type, while the western and eastern ranges have a subtropical climate of the dinaric type. At the highest points of the Andean region, climates are colder than the ones occurring at the highest point of the Norwegian fjords. In the Andean plateaus, the warm climate prevails, although it is tempered by the altitude, while in the coastal strip, there is an equatorial climate of the Guinean type. From this point until the north of the Chilean coast appear, successively, Mediterranean oceanic climate, temperate of the Breton type and, already in Tierra del Fuego, cold climate of the Siberian type.
The distribution of rainfall is related to the regime of winds and air masses. In most of the tropical region east of the Andes, winds blowing from the northeast, east and southeast carry moisture from the Atlantic, causing abundant rainfall. However, due to a consistently strong wind shear and a weak Intertropical Convergence Zone, South Atlantic tropical cyclones are rare. In the Orinoco Llanos and in the Guianas Plateau, the precipitation levels go from moderate to high. The Pacific coast of Colombia and northern Ecuador are rainy regions, with Chocó in Colombia being the rainiest place in the world along with the northern slopes of Indian Himalayas. The Atacama Desert, along this stretch of coast, is one of the driest regions in the world. The central and southern parts of Chile are subject to extratropical cyclones, and most of the Argentine Patagonia is desert. In the Pampas of Argentina, Uruguay and South of Brazil the rainfall is moderate, with rains well distributed during the year. The moderately dry conditions of the Chaco oppose the intense rainfall of the eastern region of Paraguay. In the semiarid coast of the Brazilian Northeast the rains are linked to a monsoon regime.
Important factors in the determination of climates are sea currents, such as the current Humboldt and Falklands. The equatorial current of the South Atlantic strikes the coast of the Northeast and there is divided into two others: the current of Brazil and a coastal current that flows to the northwest towards the Antilles, where there it moves towards northeast course thus forming the most Important and famous ocean current in the world, the Gulf Stream.


Physiographically, South America also includes some of the nearby islands. The Dutch ABC islands (Aruba, Bonaire, and Curaçao), the islands of Trinidad and Tobago (Trinidad Island and Tobago Island etc.), the State of Nueva Esparta, and the Federal Dependencies of Venezuela sit on the northern portion of the South American continental shelf and are sometimes considered parts of the continent. Geopolitically, all the island countries and territories in the Caribbean have generally been grouped as a subregion of North America instead. By contrast, Aves Island (administered by Venezuela) and the Archipelago of San Andrés, Providencia and Santa Catalina (San Andrés Island, Providencia Island, and Santa Catalina Island etc., which are administered by Colombia) are politically parts of South American countries but physiographically parts of North America.
Other islands often associated with geopolitical South America are the Chiloé Archipelago and Robinson Crusoe Island (both administered by Chile), Easter Island (culturally a part of Oceania, also administered by Chile), the Galápagos Islands (administered by Ecuador, sometimes considered part of Oceania), and Tierra del Fuego (split between Argentina and Chile). In the Atlantic Ocean, Brazil administers Fernando de Noronha, Trindade and Martim Vaz, and the Saint Peter and Saint Paul Archipelago, while the Falkland Islands (Spanish: Islas Malvinas) and South Georgia and the South Sandwich Islands (biographically and hydrologically associated with Antarctica) have been administered as two British Overseas Territories under the Crown, whose sovereignty over the islands is disputed by Argentina.


South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere. It can also be described as the southern subregion of a single continent called America.
South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island (dependency of Norway), Panama, and Trinidad and Tobago may also be considered parts of South America.
South America has an area of 17,840,000 square kilometers (6,890,000 sq mi). Its population as of 2021 has been estimated at more than 434 million. South America ranks fourth in area (after Asia, Africa, and North America) and fifth in population (after Asia, Africa, Europe, and North America). Brazil is by far the most populous South American country, with more than half of the continent's population, followed by Colombia, Argentina, Venezuela and Peru. In recent decades, Brazil has also generated half of the continent's GDP and has become the continent's first regional power.
Most of the population lives near the continent's western or eastern coasts while the interior and the far south are sparsely populated. The geography of western South America is dominated by the Andes mountains; in contrast, the eastern part contains both highland regions and vast lowlands where rivers such as the Amazon, Orinoco and Paraná flow. Most of the continent lies in the tropics, except for a large part of the Southern Cone located in the middle latitudes.
The continent's cultural and ethnic outlook has its origin with the interaction of indigenous peoples with European conquerors and immigrants and, more locally, with African slaves. Given a long history of colonialism, the overwhelming majority of South Americans speak Spanish or Portuguese, and societies and states are rich in Western traditions. Relative to Europe, Asia and Africa, 20th-century South America has been a peaceful continent with few wars.


The leaves are generally arranged spirally, but have an opposite arrangement in some species. They can be simple or pinnately compound (either odd- or even-pinnate). Compound leaves appear in around 30 genera. The leaf margin is most often serrate. Paired stipules are generally present, and are a primitive feature within the family, independently lost in many groups of Amygdaloideae (previously called Spiraeoideae). The stipules are sometimes adnate (attached surface to surface) to the petiole. Glands or extrafloral nectaries may be present on leaf margins or petioles. Spines may be present on the midrib of leaflets and the rachis of compound leaves.


The phylogenetic relationships between the three subfamilies within Rosaceae are unresolved. There are three competing hypotheses:


Rosaceae can be woody trees, shrubs, climbers or herbaceous plants. The herbs are mostly perennials, but some annuals also exist.
