North America is a continent in the Northern and Western hemispheres. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the south and west by the Pacific Ocean.
North America covers an area of around 24,709,000 square kilometers (9,540,000 square miles), representing approximately 16.5% of Earth's land area and 4.8% of its total surface area. It is the third-largest continent by size after Asia and Africa, and the fourth-largest continent by population after Asia, Africa, and Europe. As of 2021, North America's population is estimated at over 592 million people in 23 independent states and territories, or about 7.5% of the world's population.
The continent includes the subregions of Northern America (comprising Canada, Greenland, and the continental United States as well as the insular territories of Bermuda and Saint Pierre and Miquelon) and Middle America (comprising Mexico, Central America and the Caribbean). In human geography, the terms "North America" and "North American" often refer to just Northern America.
It is unknown exactly how and when the first human populations reached North America. People are known to have lived in the Americas at least 20,000 years ago, but various evidence points to possibly earlier dates. The Paleo-Indian period in North America followed the Last Glacial Period, and lasted until about 10,000 years ago when the Archaic period began. The classic stage followed the Archaic period, and lasted from approximately the 6th to 13th centuries. Norse exploration and colonization began in the late 10th century; the Norse built several settlements in Greenland and at least one settlement in Newfoundland.
Beginning in 1492, the voyages of Christopher Columbus led to a transatlantic exchange, including migrations of European settlers during the Age of Discovery and the early modern period. Present-day cultural and ethnic patterns reflect interactions between early European colonists, indigenous peoples, enslaved Africans, later immigrants from Europe and Asia, and descendants of these respective groups. European colonization has led to most North Americans speaking European languages (such as English, Spanish, and French) and the cultures of the region commonly reflect Western traditions. However, there remain significant indigenous populations that continue to adhere to their respective pre-colonial cultural and linguistic traditions.
Name
The Americas were named after the Italian explorer Amerigo Vespucci by German cartographers Martin Waldseemüller and Matthias Ringmann. Vespucci explored South America between 1497 and 1502, and was the first European to suggest that the Americas represented a landmass then unknown to the Europeans. In 1507, Waldseemüller published a world map, and placed the word "America" on the continent of present-day South America. The continent north of present-day Mexico was then referred to as Parias. On a 1553 world map published by Petrus Apianus, North America was called "Baccalearum", meaning "realm of the Cod fish", in reference to the abundance of cod on the East Coast.

Waldseemüller used the Latinized version of Vespucci's name, Americus Vespucius, in its feminine form of "America", following the examples of "Europa", "Asia", and "Africa". Americus originated from Medieval Latin Emericus (see Saint Emeric of Hungary), coming from the Old High German name Emmerich. Map makers later extended the name America to North America.
In 1538, Gerardus Mercator used the term America on his world map of the entire Western Hemisphere. On his subsequent 1569 map, Mercator called North America "America or New India" (America sive India Nova).
The Spanish Empire called its territories in North and South America "Las Indias", and the name given to the state body that oversaw the region was called the Council of the Indies.
Definition
The United Nations and its statistics division recognize North America as comprising three subregions: Northern America, Central America (which includes Mexico), and the Caribbean. In the limited context of regional trade agreements such as NAFTA, the term is used to reference three countries: Canada, Mexico, and the United States.
According to the six-continent model, which is prevalent in Latin America and across the Romance-speaking world as well as in Greece, "North America" designates a subregion comprising Canada, Mexico, Saint Pierre and Miquelon, and the United States; and often Bermuda, Clipperton Island, and Greenland.
North America has historically been known by other names, including Spanish North America, New Spain, New France, British North America and América Septentrional, the first official name given to Mexico.
Regions
North America includes several regions and subregions, each of which have their own respective cultural, economic, and geographic regions. Economic regions include several regions formalized in 20th- and 21st-century trade agreements, including NAFTA between Canada, Mexico, and the United States, and CAFTA between Central America, the Dominican Republic, and the United States.
North America is divided linguistically and culturally into two primary regions, Anglo-America and Latin America. Anglo-America includes most of North America, Belize, and Caribbean islands with English-speaking populations. There are also regions, including Louisiana and Quebec, with large Francophone populations; in Quebec and Saint Pierre and Miquelon, French is the official language..
The southern portion of North America includes Central America and non-English-speaking Caribbean nations. The north of the continent maintains recognized regions as well. In contrast to the common definition of North America, which encompasses the whole North American continent, the term "North America" is sometimes used more narrowly to refer only to four nations, Canada, Greenland, Mexico, and the U.S. The U.S. Census Bureau includes Saint Pierre and Miquelon, but excludes Mexico from its definition.
The term Northern America refers to the northernmost countries and territories of North America: the U.S., Bermuda, Canada, Greenland, and St. Pierre and Miquelon. Although the term does not refer to a unified region, Middle America includes Mexico, Central America, and the Caribbean.
North America's largest countries by land area are Canada and the U.S., both of which have well-defined and recognized subregions. In Canada, these include (from east to west) Atlantic Canada, Central Canada, the Canadian Prairies, the British Columbia Coast, Western Canada, and Northern Canada. In the U.S., they include New England, the Mid-Atlantic, and the South Atlantic, East North Central, West North Central, East South Central, West South Central, Mountain, and Pacific states. The Great Lakes region and the Pacific Northwest include areas in both the U.S. and Canada.
History
Pre-Columbian era
The indigenous peoples of the Americas have many creation myths, some of which assert that they have been present on the land since its creation, but there is no evidence that humans evolved there. The specifics of the initial settlement of the Americas by ancient Asians are subject to ongoing research and discussion. The traditional theory has been that hunters entered the Bering Land Bridge between eastern Siberia and present-day Alaska from 27,000 to 14,000 years ago. A growing viewpoint is that the first American inhabitants sailed from Beringia some 13,000 years ago, with widespread habitation of the Americas during the end of the Last Glacial Period, in what is known as the Late Glacial Maximum, around 12,500 years ago. The oldest petroglyphs in North America date from 15,000 to 10,000 years before present. Genetic research and anthropology indicate additional waves of migration from Asia via the Bering Strait during the Early-Middle Holocene.
Prior to the arrival of European explorers and colonists in North America, the natives of North America were divided into many different polities, ranging from small bands of a few families to large empires. They lived in several culture areas, which roughly correspond to geographic and biological zones that defined the representative cultures and lifestyles of the indigenous people who lived there, including the bison hunters of the Great Plains and the farmers of Mesoamerica. Native groups also are classified by their language families, which included Athabaskan and Uto-Aztecan languages. Indigenous peoples with similar languages did not always share the same material culture, however, and were not necessarily always allies. Anthropologists speculate that the Inuit of the high Arctic arrived in North America much later than other native groups, evidenced by the disappearance of Dorset culture artifacts from the archaeological record and their replacement by the Thule people.
During the thousands of years of native habitation on the continent, cultures changed and shifted. One of the oldest yet discovered is the Clovis culture (c. 9550–9050 BCE) in modern New Mexico. Following the early Archaic period, major regional developments included the Mississippian culture (spanning the Mississippi River valley with platform-mound urban centers) and the Ancestral Puebloans of the Four Corners region. The more southern cultural groups of North America were responsible for the domestication of many common crops now used around the world, such as tomatoes, squash, and maize. As a result of the development of agriculture in the south, many other cultural advances were made there. The Mayans developed a writing system, built huge pyramids and temples, had a complex calendar, and developed the concept of zero around 400 CE.
The first recorded European references to North America are in Norse sagas where it is referred to as Vinland. The earliest verifiable instance of pre-Columbian trans-oceanic contact by any European culture with the North America mainland has been dated to around 1000 CE. The site, situated at the northernmost extent of the island named Newfoundland, has provided unmistakable evidence of Norse settlement. Norse explorer Leif Erikson (c. 970–1020 CE) is thought to have visited the area. Erikson was the first European to make landfall on the continent (excluding Greenland).
The Mayan culture was still present in southern Mexico and Guatemala when the Spanish conquistadors arrived, but political dominance in the area had shifted to the Aztec Empire, whose capital city Tenochtitlan was located further north in the Valley of Mexico. The Aztecs were conquered in 1521 by Hernán Cortés.
Post-contact, 1492–1910
During the so-called Age of Discovery, Europeans explored overseas and staked claims to various parts of North America, much of which was already settled by indigenous peoples. Upon Europeans' arrival in the "New World", indigenous peoples had a variety of reactions, including curiosity, trading, cooperation, resignation, and resistance. The indigenous population declined substantially following European arrival, primarily due to the introduction of Eurasian diseases, such as smallpox, to which the indigenous peoples lacked immunity, and because of violent conflicts with Europeans. Indigenous culture changed significantly and their affiliation with political and cultural groups also changed. Several linguistic groups died out, and others changed quite quickly.
On North America's southeastern coast, Spanish explorer Juan Ponce de León, who had accompanied Columbus's second voyage, visited and named in 1513 La Florida. As the colonial period unfolded, Spain, England, and France appropriated and claimed extensive territories on North America's eastern and southern coastlines. Spain established permanent settlements on the Caribbean islands of Hispaniola and Cuba in the 1490s, building cities, putting the resident indigenous populations to work, raising crops for Spanish settlers and panning gold to enrich the Spaniards. Much of the indigenous population died due to disease and overwork, spurring the Spaniards on to claim new lands and peoples. An expedition under the command of Spanish settler, Hernán Cortés, sailed westward in 1519 to what turned out to be the mainland in Mexico. With local indigenous allies, the Spanish conquered the Aztec empire in central Mexico in 1521. Spain then established permanent cities in Mexico, Central America, and Spanish South America in the sixteenth century. Once Spaniards conquered the high civilization of the Aztecs and Incas, the Caribbean was a backwater of the Spanish empire.
Other European powers began to intrude on areas claimed by Spain, including the Caribbean islands. France took the western half of Hispaniola and developed Saint-Domingue as a cane sugar producing colony worked by black slave labor. Britain took Barbados and Jamaica, and the Dutch and Danes took islands previously claimed by Spain. Britain did not begin settling on the North American mainland until a hundred years after the first Spanish settlements, since it sought first to control nearby Ireland.
English settlements
The first permanent English settlement was in Jamestown, Virginia in 1607, followed by additional colonial establishments on the east coast from present-day Georgia in the south to Massachusetts in the north, forming the Thirteen Colonies of British America. The English did not establish settlements north or east of the St. Lawrence Valley in present-day Canada until after the conclusion of the American Revolutionary War. Britain's early settlements in present-day Canada included St. John's, Newfoundland in 1630 and Halifax, Nova Scotia in 1749. The first permanent French settlement was in Quebec City, Quebec, established in 1608.
Seven Years' War
With the British victory in the Seven Years' War, France in 1763 ceded to Britain its claims of North American territories east of the Mississippi River. Spain, in turn, gained rights to the territories west of Mississippi, which then served as a border between Spain and Britain's territorial claims. French colonists settled Illinois Country after several generations of experience on North America, migrating over the Mississippi River to regions where Spain was not present and where they were able to leverage their earlier Louisiana French settlements around the Gulf of Mexico. These early French settlers partnered with midwest indigenous tribes, and their mixed ancestry descendants later followed a westward expansion all the way to the Pacific Ocean on the present-day U.S. West Coast.
American Revolution
In 1776, after various attempts to reconcile differences with the British, the Thirteen Colonies in British America sent delegates to the Second Continental Congress in Philadelphia, who unanimously adopted the Declaration of Independence on 4 July 1776, written primarily by Thomas Jefferson, a member of the Committee of Five charged by the Second Continental Congress with authoring it. In the Declaration, the thirteen colonies declared their independence from the British monarchy, then governed by King George III, and detailed the factors that contributed to their decision. With the signing and issuance of the Declaration of Independence, the thirteen colonies formalized and escalated the American Revolutionary War, which had begun the year before at the Battles of Lexington and Concord on 19 April 1775. Gathered in Philadelphia following the war's outbreak, delegates from the thirteen colonies established the Continental Army from various patriot militias then engaged in resisting the British, and appointed George Washington as the Continental Army's military commander.
As the American Revolutionary War progressed, France and Spain, both then enemies of Britain, began to ultimately see the promise of a potential American victory in the war and began supporting Washington and the American Revolutionary cause. The British Army, in turn, was supported by Hessian military units from present-day Germany.
In 1783, after an eight-year attempt to defeat the American rebellion, King George III acknowledged Britain's defeat in the war, leading to the signing of the Treaty of Paris on 3 September 1783, which solidified the sovereign establishment of the United States.
Westward expansion
By the late 18th century, Russia was established on the Pacific Northwest northern coastline, where it was engaged in maritime fur trade and was supported by various indigenous settlements in the region. As a result, the Spanish were showing more interest in controlling the trade on the Pacific coast and mapped most of its coastline. The first Spanish settlements were attempted in Alta California during that period. Numerous overland explorations associated with voyageurs, fur trade, and U.S. led expeditions, including the Lewis and Clark, Frémont and Wilkes expeditions, reached the Pacific.
In 1803, during the presidency of Thomas Jefferson, the third U.S. president, Napoleon Bonaparte sold France's remaining North American territorial claims, which included regions west of the Mississippi River, to the U.S., in the Louisiana Purchase. Spain and the U.S. settled their western boundary dispute in 1819 in the Adams–Onís Treaty. Mexico fought a lengthy war for independence from Spain, winning it for Mexico (which included Central America at the time) in 1821. The U.S. sought further westward expansion and fought the Mexican–American War, gaining a vast territory that first Spain and then Mexico claimed but which they did not effectively control. Much of the area was in fact dominated by indigenous peoples, which did not recognize the claims of Spain, France, or the U.S. Russia sold its North American claims, which included the present-day U.S. state of Alaska, to the U.S. in 1867.
Canada and Panama Canal
In 1867, colonial settlers north of the United States, unified as the dominion of Canada. The U.S. sought to dig a canal across the Isthmus of Panama in present-day Panama in Central America, then a part of present-day Colombia. The U.S. aided Panamanians in a war that resulted in its separation from Colombia. The U.S. subsequently carved out the Panama Canal Zone, and claimed sovereignty over it. After decades of work, the Panama Canal was completed, which connected the Atlantic and Pacific oceans in 1913 and greatly facilitated global shipping navigation.
Geography
North America occupies the northern portion of the landmass generally referred to as the New World, the Western Hemisphere, the Americas, or simply America, which, in many countries, is considered a single continent with North America a subcontinent. North America is the third-largest continent by area after Asia and Africa.
North America's only land connection to South America is in present-day Panama at the Darien Gap on the Colombia–Panama border, placing almost all of Panama within North America. Alternatively, some geologists physiographically locate its southern limit at the Isthmus of Tehuantepec, Mexico, with Central America extending southeastward to South America from this point. The Caribbean islands, or West Indies, are considered part of North America. The continental coastline is long and irregular. The Gulf of Mexico is the largest body of water indenting the continent, followed by Hudson Bay. Others include the Gulf of Saint Lawrence and the Gulf of California.
Before the Central American isthmus formed, the region had been underwater. The islands of the West Indies delineate a submerged former land bridge, which had connected North and South America via what are now Florida and Venezuela.
There are several islands off the continent's coasts; principally, the Arctic Archipelago, the Bahamas, Turks and Caicos, the Greater and Lesser Antilles, the Aleutian Islands (some of which are in the Eastern Hemisphere proper), the Alexander Archipelago, the many thousand islands of the British Columbia Coast, and Newfoundland. Greenland, a self-governing Danish island, and the world's largest, is on the same tectonic plate (the North American Plate) and is part of North America geographically. In a geologic sense, Bermuda is not part of the Americas, but an oceanic island that was formed on the fissure of the Mid-Atlantic Ridge over 100 million years ago (mya). The nearest landmass to it is Cape Hatteras, North Carolina. However, Bermuda is often thought of as part of North America, especially given its historical, political and cultural ties to Virginia and other parts of the continent.
The vast majority of North America is on the North American Plate. Parts of western Mexico, including Baja California, and of California, including the cities of San Diego, Los Angeles, and Santa Cruz, lie on the eastern edge of the Pacific Plate, with the two plates meeting along the San Andreas Fault. The southernmost portion of the continent and much of the West Indies lie on the Caribbean Plate, whereas the Juan de Fuca Plate and Cocos Plate border the North American Plate on its western frontier.
The continent can be divided into four great regions (each of which contains many subregions): the Great Plains stretching from the Gulf of Mexico to the Canadian Arctic; the geologically young, mountainous west, including the Rocky Mountains, the Great Basin, California, and Alaska; the raised but relatively flat plateau of the Canadian Shield in the northeast; and the varied eastern region, which includes the Appalachian Mountains, the coastal plain along the Atlantic seaboard, and the Florida peninsula. Mexico, with its long plateaus and cordilleras, falls largely in the western region, although the eastern coastal plain does extend south along the Gulf.
The western mountains are split in the middle into the main range of the Rockies and the coast ranges in California, Oregon, Washington, and British Columbia, with the Great Basin—a lower area containing smaller ranges and low-lying deserts—in between. The highest peak is Denali (also called Mount McKinley) in Alaska.
The U.S. Geographical Survey (USGS) states that the geographic center of North America is "6 miles [10 km] west of Balta, Pierce County, North Dakota" at about 48°10′N 100°10′W, about 24 kilometers (15 mi) from Rugby, North Dakota. The USGS further states that "No marked or monumented point has been established by any government agency as the geographic center of either the 50 states, the conterminous United States, or the North American continent." Nonetheless, there is a 4.6-meter (15 ft) field stone obelisk in Rugby claiming to mark the center. The North American continental pole of inaccessibility is located 1,650 km (1,030 mi) from the nearest coastline, between Allen and Kyle, South Dakota at 43.36°N 101.97°W / 43.36; -101.97 (Pole of Inaccessibility North America).
Canada
Canada can be divided into roughly seven physiographic divisions:
