Etymology and naming

The name "America" was first recorded in 1507. A two-dimensional globe created by Martin Waldseemüller was the earliest recorded use of the term. The name was also used (together with the related term ''Amerigen'') in the '' Cosmographiae Introductio'', apparently written by Matthias Ringmann, in reference to South America. It was applied to both North and South America by
Gerardus Mercator Gerardus Mercator (; 5 March 1512 – 2 December 1594) was a 16th-century geographer, cosmographer and cartographer from the County of Flanders. He is most renowned for creating the 1569 world map based on a new projection which represented ...

History


Pre-Columbian era

The pre-Columbian era incorporates all period subdivisions in the history and prehistory of the Americas before the appearance of significant European influences on the American continents, spanning the time of the original settlement in the Upper Paleolithic to European colonization during the Early Modern period. The term ''Pre-Columbian'' is used especially often in the context of the great indigenous civilizations of the Americas, such as those of Mesoamerica (the Olmec, the Toltec, the Teotihuacano, the Zapotec, the Mixtec, the Aztec, and the Maya) and the

investigations. Others were contemporary with this period, and are also known from historical accounts of the time. A few, such as the Maya, had their own written records. However, most Europeans of the time viewed such texts as pagan, and much was destroyed in Christian pyres. Only a few hidden documents remain today, leaving modern historians with glimpses of ancient culture and knowledge.


Settlement

The first inhabitants migrated into the Americas from Asia. Habitation sites are known in

Beyond that, the specifics of the Paleo-Indian migration to and throughout the Americas, including the dates and routes traveled, are subject to ongoing research and discussion. Widespread habitation of the Americas occurred during the late glacial maximum, from 16,000 to 13,000 years ago. The traditional theory has been that these early migrants moved into the

land bridge between eastern Siberia and present-day Alaska around 40,000–17,000 years ago, when sea levels were significantly lowered during the Quaternary glaciation. These people are believed to have followed herds of now-extinct pleistocene megafauna along ''ice-free corridors'' that stretched between the Laurentide and Cordilleran ice sheets. Another route proposed is that, either on foot or using primitive boats, they migrated down the Pacific coast to South America. Evidence of the latter would since have been covered by a sea level rise of hundreds of meters following the last ice age. Both routes may have been taken, although the genetic evidences suggests a single founding population. The micro-satellite diversity and distributions specific to South American Indigenous people indicates that certain populations have been isolated since the initial colonization of the region. A second migration occurred after the initial peopling of the Americas; Na Dene speakers found predominantly in North American groups at varying genetic rates with the highest frequency found among the Athabaskans at 42% derive from this second wave.

Lucas Vázquez de Ayllón established San Miguel de Guadalupe, the first European settlement in what is now the United States, on the Pee Dee River in South Carolina. During the first half of the 16th century, Spanish colonists conducted raids throughout the Caribbean Basin, bringing captives from Central America, northern South America, and Florida back to Hispaniola and other Spanish settlements. France, led by Jacques Cartier and Giovanni da Verrazano, focused primarily on North America. English explorations of the Americas were led by John Cabot, Giovanni Caboto and Sir Walter Raleigh. The Dutch in New Netherland confined their operations to Manhattan Island, Long Island, the Hudson River Valley, and what later became New Jersey.

After the Dominican War of Independence, Dominican Republic won independence from Haiti, it was re-annexed by Spain in 1861, but reclaimed its independence in 1865 at the conclusion of the Dominican Restoration War. The last violent episode of decolonization was the Cuban War of Independence which became the Spanish–American War, which resulted in the independence of Cuba in 1898, and the transfer of sovereignty over Puerto Rico from Spain to the United States. Peaceful decolonization began with the purchase by the United States of Louisiana Purchase, Louisiana from France in 1803, Adams–Onís Treaty, Florida from Spain in 1819, of Alaska purchase, Alaska from Russia in 1867, and the Treaty of the Danish West Indies, Danish West Indies from Denmark in 1916. Canada became independent of the United Kingdom, starting with the Balfour Declaration of 1926, Statute of Westminster 1931, and ending with the patriation of the Canadian Constitution in 1982. The Dominion of Newfoundland similarly achieved independence under the Balfour Declaration and Statute of Westminster, but relinquished self-rule in 1934. It was subsequently Newfoundland Act, confederated with Canada in 1949. The remaining European colonies in the Caribbean began to achieve peaceful independence well after World War II. Jamaica and Trinidad and Tobago became independent in 1962, and Guyana and Barbados both achieved independence in 1966. In the 1970s, the Bahamas, Grenada, Dominica, St. Lucia, and St. Vincent and the Grenadines all became independent of the United Kingdom, and Suriname became independent of the Netherlands. Belize, Antigua and Barbuda, and Saint Kitts and Nevis achieved independence from the United Kingdom in the 1980s.


Geography


Extent

The Americas make up most of the land in Earth's Western Hemisphere. The northernmost point of the Americas is Kaffeklubben Island, which is the most northerly point of land on Earth. The southernmost point is the islands of Southern Thule, although they are sometimes considered part of Antarctica. The mainland of the Americas is the world's longest north-to-south landmass. The distance between its two polar extremities, Murchison Promontory on the Boothia Peninsula in northern Canada and Cape Froward in Chilean Patagonia, is roughly . The mainland's most westerly point is the end of the Seward Peninsula in Alaska; Attu Island, further off the Alaskan coast to the west, is considered the westernmost point of the Americas. Ponta do Seixas in northeastern Brazil forms the easternmost extremity of the mainland, while Nordostrundingen, in Greenland, is the most easterly point of the continental shelf.


Geology

South America broke off from the west of the supercontinent Gondwana around 135 million years ago, forming its own continent. Around 15 million years ago, the collision of the Caribbean Plate and the Pacific Plate resulted in the emergence of a series of volcanoes along the border that created a number of islands. The gaps in the archipelago of Central America filled in with material eroded off North America and South America, plus new land created by continued volcanism. By three million years ago, the continents of North America and South America were linked by the Isthmus of Panama, thereby forming the single landmass of the Americas. The Great American Interchange resulted in many species being spread across the Americas, such as the cougar, New World porcupine, porcupine, opossums, armadillos and hummingbirds.


Topography

The geography of the western Americas is dominated by the

is the tallest. Between its coastal mountain ranges, North America has vast flat areas. The Interior Plains spread over much of the continent, with low relief. The Canadian Shield covers almost 5 million km2 of North America and is generally quite flat. Similarly, the north-east of South America is covered by the flat Amazon basin. The Brazilian Highlands on the east coast are fairly smooth but show some variations in landform, while farther south the Gran Chaco and Pampas are broad lowlands.


Climate

The climate of the Americas varies significantly from region to region. Tropical rainforest climate occurs in the latitudes of the Amazon rainforest, Amazon, American cloud forests, southeastern Florida and Darién Gap. In the Rocky Mountains and
Andes The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S ...
, dry and continental climates are observed. Often the higher altitudes of these mountains are snow-capped. Southeastern North America is well known for its occurrence of tornadoes and hurricanes, of which the vast majority of tornadoes occur in the United States' Tornado Alley, as well as in the southerly Dixie Alley in the North American late-winter and early spring seasons. Often parts of the Caribbean are exposed to the violent effects of hurricanes. These weather systems are formed by the collision of dry, cool air from Canada and wet, warm air from the Atlantic.


Hydrology

With coastal mountains and interior plains, the Americas have several large river basins that drain the continents. The largest river basin in North America is that of the Mississippi River, Mississippi, covering the second largest Drainage basin, watershed on the planet. The Mississippi-Missouri river system drains most of 31 states of the U.S., most of the Great Plains, and large areas between the Rocky and Appalachian mountains. This river is the List of rivers by length, fourth longest in the world and List of rivers by discharge, tenth most powerful in the world. In North America, to the east of the Appalachian Mountains, there are no major rivers but rather a series of rivers and streams that flow east with their terminus in the Atlantic Ocean, such as the Hudson River, Saint John River (Bay of Fundy), Saint John River, and Savannah River. A similar instance arises with central Canadian rivers that drain into Hudson Bay; the largest being the Churchill River (Hudson Bay), Churchill River. On the west coast of North America, the main rivers are the Colorado River, Columbia River, Yukon River, Fraser River, and Sacramento River. The Colorado River drains much of the Southern Rockies and parts of the Basin and Range Province. The river flows approximately into the Gulf of California, during which over time it has carved out natural phenomena such as the Grand Canyon and created phenomena such as the Salton Sea. The Columbia is a large river, long, in central western North America and is the most powerful river on the West Coast of the Americas. In the far northwest of North America, the Yukon drains much of the Alaskan peninsula and flows from parts of Yukon and the Northwest Territory to the Pacific. Draining to the Arctic Ocean of Canada, the Mackenzie River drains waters from the Arctic Great Lakes of Arctic Canada, as opposed to the Saint-Lawrence River that drains the Great Lakes of Southern Canada into the Atlantic Ocean. The Mackenzie River is the largest in Canada and drains . The largest river basin in South America is that of the Amazon Basin, Amazon, which has the highest volume flow of any river on Earth. The second largest watershed of South America is that of the Paraná River, which covers about 2.5 million km2.


Ecology

North America and South America began to develop a shared population of flora and fauna around 2.5 million years ago, when continental drift brought the two continents into contact via the Isthmus of Panama. Initially, the exchange of biota was roughly equal, with North American genera migrating into South America in about the same proportions as South American genera migrated into North America. This exchange is known as the Great American Interchange. The exchange became lopsided after roughly a million years, with the total spread of South American genera into North America far more limited in scope than the spread on North American genera into South America.


Countries and territories

There are 35 sovereign states in the Americas, as well as an Danish Realm, autonomous country of Denmark, three overseas departments of France, three Overseas collectivity, overseas collectivities of France, and one uninhabited territory of France, eight British Overseas Territories, overseas territories of the United Kingdom, three Kingdom of the Netherlands, constituent countries of the Netherlands, three Public body (Netherlands), public bodies of the Netherlands, two Territories of the United States, unincorporated territories of the United States, and one uninhabited territory of the United States.


Demography


Population

In 2021 the total population of the Americas was about 1.03 billion people, divided as follows: * North America: 596.6 million (includes Central America and the Caribbean) * South America: 434.3 million


Largest urban centers

There are three urban centers that each hold titles for being the largest population area based on the three main demographic concepts: * City proper :A city proper is the locality with legally fixed boundaries and an administratively recognized urban status that is usually characterized by some form of local government. * Urban area :An urban area is characterized by higher population density and vast human features in comparison to areas surrounding it. Urban areas may be cities, towns or conurbations, but the term is not commonly extended to rural settlements such as villages and hamlets. Urban areas are created and further developed by the process of urbanization and do not include large swaths of rural land, as do metropolitan areas. * Metropolitan area :Unlike an urban area, a metropolitan area includes not only the urban area, but also satellite cities ''plus intervening rural land'' that is socio-economically connected to the urban core city, typically by employment ties through commuting, with the urban core city being the primary labor market. In accordance with these definitions, the three largest population centers in the Americas are: Mexico City, anchor to the largest metropolitan area in the Americas; New York City, anchor to the largest urban area in the Americas; and São Paulo, the largest city proper in the Americas. All three cities maintain Global city#Alpha, Alpha classification and large scale influence.

Ethnology

The population of the Americas is made up of the descendants of four large ethnic groups and their combinations. * The Indigenous peoples of the Americas, being Amerindians and Inuit-Yupik peoples, Yupik-Aleut people, Unangan. * Those of European ancestry, mainly Spanish, British and Irish, Portuguese people, Portuguese, Germans, German, Italians, Italian, French people, French and Dutch (ethnic group), Dutch. * Those of Afro-American peoples of the Americas, African ancestry, mainly of West African descent. * Asian people, Asians, that is, those of Eastern Asia, Eastern, South Asia, South, and Southeast Asian ancestry. * Mestizos (Metis people, Métis people in Canada), those of mixed European and Amerindian ancestry. * Mulattoes, people of mixed African and European ancestry. * Zambos (Spanish) or Cafuzos (Portuguese), those of mixed African and Indigenous ancestry. The majority of the population live in Latin America, named for its predominant cultures, rooted in Romance-speaking Europe, Latin Europe (including the two dominant languages, Spanish and Portuguese language, Portuguese, both Romance languages), more specifically in the Iberian Peninsula, Iberian nations of Portugal and Spain (hence the use of the term Ibero-America as a synonym). Latin America is typically contrasted with Anglo-America, where English, a Germanic language, is prevalent, and which comprises Canada (with the exception of Canadian French, francophone Canada rooted in Latin Europe [France]—see Québec and Acadia) and the United States.

Languages

Various languages are spoken in the Americas. Some are of European origin, others are spoken by indigenous peoples or are the mixture of various languages like the different creoles. The most widely spoken first language in the Americas is Spanish language, Spanish, followed by English and Brazilian Portuguese. The dominant language of Latin America is Spanish, though the most populous nation in Latin America,
Brazil Brazil ( pt, Brasil; ), officially the Federative Republic of Brazil (Portuguese: ), is the largest country in both South America and Latin America. At and with over 217 million people, Brazil is the world's fifth-largest country by area ...
, speaks Portuguese language, Portuguese. Small enclaves of French language, French-, Dutch language, Dutch- and English-speaking regions also exist in Latin America, notably in French Guiana, Suriname, and Belize and Guyana respectively. Haitian Creole is dominant in the nation of Haiti, where French is also spoken. Indigenous languages of the Americas, Native languages are more prominent in Latin America than in Anglo-America, with Nahuatl language, Nahuatl, Quechua languages, Quechua, Aymara language, Aymara and Guaraní language, Guaraní as the most common. Various other native languages are spoken with less frequency across both Anglo-America and Latin America. Creole languages other than Haitian Creole are also spoken in parts of Latin America. The dominant language of Anglo-America is English. French is also official in Canada, where it is the predominant language in Quebec and an official language in New Brunswick along with English. It is also an important language in Louisiana, and in parts of New Hampshire, Maine, and Vermont. Spanish has kept an ongoing presence in the Southwestern United States, which formed part of the Viceroyalty of New Spain, especially in Californio, California and New Mexico, where New Mexican Spanish, a distinct variety of Spanish spoken since the 17th century has survived. It has more recently become widely spoken in other parts of the United States because of heavy immigration from Latin America. High levels of immigration in general have brought great linguistic diversity to Anglo-America, with over 300 languages known to be spoken in the United States alone, but most languages are spoken only in small enclaves and by relatively small immigrant groups. The nations of Guyana, Suriname, and Belize are generally considered not to fall into either Anglo-America or Latin America because of their language differences from Latin America, geographic differences from Anglo-America, and cultural and historical differences from both regions; English is the primary language of Guyana and Belize, and Dutch is the primary language of Suriname. Most of the non-native languages have, to different degrees, evolved differently from the mother country, but are usually still mutually intelligible. Some have combined, however, which has even resulted in completely new languages, such as Papiamento, which is a combination of Portuguese, Spanish, Dutch (representing the respective colonizers), native Arawak peoples, Arawak, various African languages, and, more recently English. The lingua franca Portuñol, a mixture of Portuguese and Spanish, is spoken in the border regions of Brazil and neighboring Spanish-speaking countries. More specifically, Riverense Portuñol language, Riverense Portuñol is spoken by around 100,000 people in the border regions of Brazil and Uruguay. Because of immigration, there are many communities where other languages are spoken from all parts of the world, especially in the United States, Brazil, Argentina, Canada, Chile, Costa Rica and Uruguay—very important destinations for immigrants.


Terminology


English

English language, Speakers of English generally refer to the landmasses of North America and South America as ''the Americas'', the '' Western Hemisphere'', or the '' New World''.Burchfield, R. W. 2004. ''Fowler's Modern English Usage.'' () Oxford, UK: Oxford University Press; p. 48. The adjective ''American'' may be used to indicate something pertains to the Americas, but this term is primarily used in English to indicate something pertaining to the United States. Some non-ambiguous alternatives exist, such as the adjective ''Pan-American'', or ''New Worlder'' as a demonym for a resident of the closely related New World. Use of ''America'' in the hemispherical sense is sometimes retained, or can occur when translated from other languages. For example, the Association of National Olympic Committees (ANOC) in Paris maintains a single continental association for "America", represented by one of the five Olympic rings. American essayist H.L. Mencken said, "The Latin-Americans use Norteamericano in formal writing, but, save in Panama, prefer nicknames in colloquial speech." quote at p 243. To avoid "American" one can use constructed terms in their languages derived from "United States" or even "North America"."America." ''Oxford Guide to Canadian English Usage.'' () Fee, Margery and McAlpine, J., ed., 1997. Toronto: Oxford University Press; p. 36. In Canada, its southern neighbor is often referred to as "the United States", "the U.S.A.", or (informally) "the States", while U.S. citizens are generally referred to as "Americans". Most Canadians resent being referred to as "Americans".


Spanish

In Spanish, ''América'' is a single continent composed of the subcontinents of ''América del Sur'' and ''América del Norte'', the land bridge of ''América Central'', and the islands of the ''Antilles, Antillas''. ''Americano'' or ''americana'' in Spanish refers to a person from ''América'' in a similar way that in which ''europeo'' or ''europea'' refers to a person from ''Europa''. The terms ''sudamericano/a'', ''centroamericano/a'', ''antillano/a'' and ''norteamericano/a'' can be used to more specifically refer to the location where a person may live. Citizens of the United States of America are normally referred to by the term ''estadounidense'' (rough literal translation: "United Statesian") instead of ''americano'' or ''americana'' which is discouraged, and the country's name itself is officially translated as ''Estados Unidos de América'' (United States of America), commonly abbreviated as ''Estados Unidos'' (EEUU). "debe evitarse el empleo de americano para referirse exclusivamente a los habitantes de los Estados Unidos" ("the use of the term ''americano'' referring exclusively to the United States inhabitants must be avoided") Also, the term ''norteamericano'' (North American) may refer to a citizen of the United States. This term is primarily used to refer to citizens of the United States, and less commonly to those of other North American countries.


Portuguese

In Portuguese, '':pt:América, América'' is a single continent composed of ''América do Sul'' (South America), ''América Central'' (Central America) and ''América do Norte'' (North America). It can be ambiguous, as ''América'' can be used to refer to the United States of America, but is avoided in print and formal environments.


French

In French the word ''américain'' may be used for things relating to the Americas; however, similar to English, it is most often used for things relating to the United States, with the term ''états-unien'' sometimes used for clarity. ''Panaméricain'' may be used as an adjective to refer to the Americas without ambiguity. French speakers may use the noun ''Amérique'' to refer to the whole landmass as one continent, or two continents, ''Amérique du Nord'' and ''Amérique du Sud''. In French, ''Amérique'' is seldom used to refer to the United States, leading to some ambiguity when it is. Similar to English usage, ''les Amériques'' or ''des Amériques'' is used to refer unambiguously to the Americas.


Dutch

In Dutch, the word ''Amerika'' mostly refers to the United States. Although the United States is equally often referred to as ''de Verenigde Staten'' ("the United States") or ''de VS'' ("the US"), ''Amerika'' relatively rarely refers to the Americas, but it is the only commonly used Dutch word for the Americas. This often leads to ambiguity; and to stress that something concerns the Americas as a whole, Dutch uses a combination, namely ''Noord- en Zuid-Amerika'' (North and South America). Latin America and Central America are generally referred to as ''Latijns Amerika'' and ''Midden-Amerika'' respectively. The adjective ''Amerikaans'' is most often used for things or people relating to the United States. There are no alternative words to distinguish between things relating to the United States or to the Americas. Dutch uses the local alternative for things relating to elsewhere in the Americas, such as ''Argentijns'' for Argentine people, Argentine, etc.
