The name America was first recorded in 1507 (together with the related term Amerigen) in the Cosmographiae Introductio, apparently written by Matthias Ringmann, in reference to South America. It first applied to both North and South America by Gerardus Mercator in 1538. Amerigen means "land of Amerigo" and derives from Amerigo and gen, the accusative case of Ancient Greek gē "earth". America accorded with the feminine names of Asia, Africa, and Europa.
In modern English, North and South America are generally considered separate continents, and taken together are called the Americas in the plural, parallel to similar situations such as the Carolinas. When conceived as a unitary continent, the form is generally the continent of America in the singular. However, without a clarifying context, singular America in English commonly refers to the United States of America.
In some countries of the world (including France, Italy, Portugal, Spain, Romania, Greece, and the countries of Latin America), America is considered a continent encompassing the North America and South America subcontinents, as well as Central America.
The first inhabitants migrated into the Americas from Asia. Habitation sites are known in Alaska and the Yukon from at least 20,000 years ago, with suggested ages of up to 40,000 years. 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 Beringia 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. Linguists and biologists have reached a similar conclusion based on analysis of Amerindian language groups and ABO blood group system distributions. Then the people of the Arctic small tool tradition a broad cultural entity that developed along the Alaska Peninsula, around Bristol Bay, and on the eastern shores of the Bering Strait around 2,500 BCE (4,500 years ago) moved into North America. The Arctic small tool tradition, a Paleo-Eskimo culture branched off into two cultural variants, including the Pre-Dorset, and the Independence traditions of Greenland. The descendants of the Pre-Dorset cultural group, the Dorset culture was displaced by the final migrants from the Bering sea coast line the ancestors of modern Inuit, the Thule people by 1000 Common Era (CE). Around the same time as the Inuit migrated into Greenland, Viking settlers began arriving in Greenland in 982 and Vinland shortly thereafter, establishing a settlement at L'Anse aux Meadows, near the northernmost tip of Newfoundland. The Viking settlers quickly abandoned Vinland, and disappeared from Greenland by 1500.
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 Andes (Inca, Moche, Muisca, Cañaris).
Many pre-Columbian civilizations established characteristics and hallmarks which included permanent or urban settlements, agriculture, civic and monumental architecture, and complex societal hierarchies. Some of these civilizations had long faded by the time of the first permanent European arrivals (c. late 15th–early 16th centuries), and are known only through archeological 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.
Although there had been previous trans-oceanic contact, large-scale European colonization of the Americas began with the first voyage of Christopher Columbus in 1492. The first Spanish settlement in the Americas was La Isabela in northern Hispaniola. This town was abandoned shortly after in favor of Santo Domingo de Guzmán, founded in 1496, the oldest American city of European foundation. This was the base from which the Spanish monarchy administered its new colonies and their expansion. On the continent, Panama City on the Pacific coast of Central America, founded on August 5, 1519, played an important role, being the base for the Spanish conquest of South America. The spread of new diseases brought by Europeans and Africans killed many of the inhabitants of North America and South America, with a general population crash of Native Americans occurring in the mid-16th century, often well ahead of European contact. European immigrants were often part of state-sponsored attempts to found colonies in the Americas. Migration continued as people moved to the Americas fleeing religious persecution or seeking economic opportunities. Millions of individuals were forcibly transported to the Americas as slaves, prisoners or indentured servants.
Decolonization of the Americas began with the American Revolution and the Haitian Revolution in the late 1700s. This was followed by numerous Latin American wars of independence in the early 1800s. Between 1811 and 1825, Paraguay, Argentina, Chile, Gran Colombia, the United Provinces of Central America, Mexico, Brazil, Peru, and Bolivia gained independence from Spain and Portugal in armed revolutions. After the 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 from France in 1803, Florida from Spain in 1819, of Alaska from Russia in 1867, and the 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 partial independence under the Balfour Declaration and Statute of Westminster, but was re-absorbed into the United Kingdom in 1934. It was subsequently 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.
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, the Boothia Peninsula in northern Canada and Cape Froward in Chilean Patagonia, is roughly 14,000 km (8,700 mi). 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.
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, porcupine, opossums, armadillos and hummingbirds.
The geography of the western Americas is dominated by the American cordillera, with the Andes running along the west coast of South America and the Rocky Mountains and other North American Cordillera ranges running along the western side of North America. The 2,300-kilometer-long (1,400 mi) Appalachian Mountains run along the east coast of North America from Alabama to Newfoundland. North of the Appalachians, the Arctic Cordillera runs along the eastern coast of Canada.
The largest mountain ranges are the Andes and Rocky Mountains. The Sierra Nevada and the Cascade Range reach similar altitudes as the Rocky Mountains, but are significantly smaller. In North America, the greatest number of fourteeners are in the United States, and more specifically in the U.S. state of Colorado. The highest peaks of the Americas are located in the Andes, with Aconcagua of Argentina being the highest; in North America Denali (Mount McKinley) in the U.S. state of Alaska 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.
The climate of the Americas varies significantly from region to region. Tropical rainforest climate occurs in the latitudes of the Amazon, American cloud forests, Florida and Darien Gap. In the Rocky Mountains and Andes, a similar climate is 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. 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.
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, covering the second largest 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 fourth longest in the world and 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, and Savannah River. A similar instance arises with central Canadian rivers that drain into Hudson Bay; the largest being the 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 Great Basin and Range Province. The river flows approximately 1,450 miles (2,330 km) 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, 1,243 miles (2,000 km) 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 1,980 miles (3,190 km) 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 1,805,200 square kilometers (697,000 sq mi).
The largest river basin in South America is that of the 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.
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.
There are 35 sovereign states in the Americas, as well as an autonomous country of Denmark, three overseas departments of France, three overseas collectivities of France, and one uninhabited territory of France, eight overseas territories of the United Kingdom, three constituent countries of the Netherlands, three public bodies of the Netherlands, two unincorporated territories of the United States, and one uninhabited territory of the United States.
The total population of the Americas is about 951 million people and is divided as follows:North America: 565 million (includes Central America and the Caribbean)
South America: 386 million
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.
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.
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 Alpha classification and large scale influence. Mexico City is the largest city in the Americas and the Western Hemisphere and Northern Hemisphere.Urban centers within the Americas
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, Inuit, and Aleuts.
Those of European ancestry, mainly Spanish, British and Irish, Portuguese, Italian, French, Polish, German, Dutch, Russians and Scandinavians.
Those of African ancestry, mainly of West African descent.
Asians, that is, those of Eastern, South, and Southeast Asian ancestry.
Mestizos (Metis people in Canada), those of mixed European and Amerindian ancestry.
Mulattoes, people of mixed African and European ancestry.
Zambos (Spanish) or Cafusos (Portuguese), those of mixed African and Amerindian ancestry.
The majority of the population live in Latin America, named for its predominant cultures, rooted in Latin Europe (including the two dominant languages, Spanish and Portuguese, both Romance languages), more specifically in the 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 francophone Canada rooted in Latin Europe [France]—see Québec and Acadia) and the United States. Both countries are located in North America, with cultures deriving predominantly from Anglo-Saxon and other Germanic roots.
The most prevalent faiths in the Americas are as follows:Christianity (86 percent)Roman Catholicism: Practiced by 69 percent of the Latin American population, 81 percent in Mexico and 61 percent in Brazil whose Roman Catholic population of 123 million is the greatest of any nation's; approximately 24 percent of the United States' population and about 39 percent of Canada's.
Protestantism: Practiced mostly in the United States, where half of the population are Protestant, and Canada, with slightly more than a quarter of the population; there is a growing contingent of Evangelical and Pentecostal movements in predominantly Catholic Latin America.
Eastern Orthodoxy: Found mostly in the United States (1 percent)and Canada; this Christian group is growing faster than many other Christian groups in Canada and now represents roughly 3 percent of the Canadian population.
Non-denominational Christians and other Christians (some 1,000 different Christian denominations and sects practiced in the Americas
Irreligion: About 12 Percent, including atheists and agnostics, as well as those who profess some form of spirituality but do not identify themselves as members of any organized religion)
Islam: Together, Muslims constitute about 1 percent of the North American population and 0.3 percent of all Latin Americans. It is practiced by 3 percent of Canadians and 0.6 percent of the U.S. population. Argentina has the largest Muslim population in Latin America with up to 600,000 persons, or 1.9 percent of the population.
Judaism (practiced by 2 percent of North Americans—approximately 2.5 percent of the U.S. population and 1.2 percent of Canadians—and 0.23 percent of Latin Americans—Argentina has the largest Jewish population in Latin America with 200,000 members)
Other faiths include Buddhism; Hinduism; Sikhism; Bahá'í Faith; a wide variety of indigenous religions, many of which can be categorized as animistic; new age religions and many African and African-derived religions. Syncretic faiths can also be found throughout the Americas.
Various languages are spoken in the Americas. Some are of European origin, others are spoken by indigenous peoples or are the mixture of various idioms like the different creoles.
The most widely spoken language in the Americas is Spanish. The dominant language of Latin America is Spanish, though the most populous nation in Latin America, Brazil, speaks Portuguese. Small enclaves of French-, Dutch- and English-speaking regions also exist in Latin America, notably in French Guiana, Suriname, and Belize and Guyana respectively, and Haitian Creole, of French origin, is dominant in the nation of Haiti. Native languages are more prominent in Latin America than in Anglo-America, with Nahuatl, Quechua, Aymara and 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 California and New Mexico, where 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 official and written 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, 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 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.
Speakers of English generally refer to the landmasses of North America and South America as the Americas, the Western Hemisphere, or the New World. 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 Americas. 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 linguist H.L. Mencken said, " The Latin-Americans use Nortamericano in formal writing, but, save in Panama, prefer nicknames in colloquial speech." To avoid "American" one can use constructed terms in their languages derived from "United States" or even "North America". 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".
In Spanish, América is a single continent composed of the subcontinents of Sudamérica and Norteamérica, the land bridge of Centroamérica, and the islands of the Antillas. Americano or americana in Spanish refers to a person from América in a similar way that 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). 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.
In Portuguese, 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.
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. 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 also used to refer to the United States, making the term ambiguous. Similar to English usage, les Amériques or des Amériques is used to refer unambiguously to the Americas.
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 is generally referred to as Latijns Amerika or Midden-Amerika for Central America.
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, etc.
