Seven Ranges Terminus is a stone surveying marker near Magnolia, Ohio that marks the completion of the first step in opening the lands northwest of the Ohio River to sale and settlement by Americans . This survey marked the first application of the rectangular plan for subdividing land.
135-844: With victory in the Revolutionary War , the Treaty of Paris granted the United States lands north of the Ohio River, south of the Great Lakes , and east of the Mississippi River , called the Northwest Territory . The US Congress adopted the Land Ordinance of 1785 as a method for surveying, selling and settling these lands. This ordinance established a method for surveying the land into
270-767: A Treaty of Alliance in February 1778. In 1779, the Sullivan Expedition undertook a scorched earth campaign against the Iroquois who were largely allied with the British. Indian raids on the American frontier, however, continued to be a problem. Also, in 1779, Spain allied with France against Great Britain in the Treaty of Aranjuez , though Spain did not formally ally with the Americans. Howe's replacement Henry Clinton intended to take
405-679: A successful siege , Washington's forces drove the British Army out of Boston in March 1776, and British commander in chief William Howe responded by launching the New York and New Jersey campaign . Howe captured New York City in November. Washington responded by clandestinely crossing the Delaware River and winning small but significant victories at Trenton and Princeton . In the summer of 1777, as Howe

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
675-533: A brief skirmish at Lexington, followed by the full-scale Battles of Lexington and Concord. British troops suffered around 300 casualties before withdrawing to Boston , which was then besieged by the militia. In May 1775, 4,500 British reinforcements arrived under Generals William Howe , John Burgoyne , and Sir Henry Clinton . On June 17, they seized the Charlestown Peninsula at the Battle of Bunker Hill ,

A banking crisis led to the near-collapse of the East India Company , which dominated the British economy; to support it, Parliament passed the Tea Act , giving it a trading monopoly in the Thirteen Colonies . Since most American tea was smuggled by the Dutch, the act was opposed by those who managed the illegal trade, while being seen as yet another attempt to impose
945-542: A frontal assault in which they suffered over 1,000 casualties. Dismayed at the costly attack which had gained them little, Gage appealed to London for a larger army, but instead was replaced as commander by Howe. On June 14, 1775, Congress took control of Patriot forces outside Boston, and Congressional leader John Adams nominated Washington as commander-in-chief of the newly formed Continental Army . On June 16, Hancock officially proclaimed him "General and Commander in Chief of
1080-486: A grid of six mile square survey townships . These townships were to be arranged into vertical rows called “Ranges”. The first ranges were to be measured from a meridian along the western boundary of Pennsylvania . The townships in each range were measured from an east-west line called a baseline . This became the genesis of the techniques used in the Public Land Survey System . The 1785 ordinance called for
1215-450: A logistically challenging and dangerous operation. Meanwhile, the Hessians were involved in numerous clashes with small bands of Patriots and were often aroused by false alarms at night in the weeks before the actual Battle of Trenton . By Christmas they were tired, while a heavy snowstorm led their commander, Colonel Johann Rall , to assume no significant attack would occur. At daybreak on

People were known to live 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
1485-595: A period of mountain building called the Laramide orogeny , between 80 and 55 mya. The formation of the Isthmus of Panama that connected the continent to South America arguably occurred approximately 12 to 15 mya, and the Great Lakes (as well as many other northern freshwater lakes and rivers) were carved by receding glaciers about 10,000 years ago. North America is the source of much of what humanity knows about geologic time periods. The geographic area that would later become

Fertile soils from weathered volcanic lavas have made it possible to sustain dense populations in agriculturally productive highland areas. Central America has many mountain ranges ; the longest are the Sierra Madre de Chiapas ,
1755-553: A rearguard. Howe met with a delegation from the Second Continental Congress at the September Staten Island Peace Conference , but it failed to conclude peace, largely because the British delegates only had the authority to offer pardons and could not recognize independence. On September 15, Howe seized control of New York City when the British landed at Kip's Bay and unsuccessfully engaged
1890-794: A riot started in Boston when the authorities seized the sloop Liberty on suspicion of smuggling. Tensions escalated further in March 1770 when British troops fired on rock-throwing civilians, killing five in what became known as the Boston Massacre . The Massacre coincided with the partial repeal of the Townshend Acts by the Tory-based North Ministry , which came to power in January 1770 and remained in office until 1781. North insisted on retaining duty on tea to enshrine Parliament's right to tax
2025-591: A second attack captured Fort Mifflin on November 16, while Fort Mercer was abandoned two days later when Cornwallis breached the walls. His supply lines secured, Howe tried to tempt Washington into giving battle, but after inconclusive skirmishing at the Battle of White Marsh from December 5 to 8, he withdrew to Philadelphia for the winter. On December 19, the Americans followed suit and entered winter quarters at Valley Forge ; while Washington's domestic opponents contrasted his lack of battlefield success with Gates' victory at Saratoga, foreign observers such as Frederick
2160-475: A struggle with Britain, but also split between American Patriots and American Loyalists. Patriots generally supported independence from Britain and a new national union in Congress, while Loyalists remained faithful to British rule. Estimates of numbers vary, one suggestion being the population as a whole was split evenly between committed Patriots, committed Loyalists, and those who were indifferent. Others calculate
2295-654: A threat to liberty in general. This led to increased sympathy for the Patriot cause locally, in the British Parliament, and in the London press. Throughout the 18th century, the elected lower houses in the colonial legislatures gradually wrested power from their governors. Dominated by smaller landowners and merchants, these assemblies now established ad-hoc provincial legislatures, variously called congresses, conventions, and conferences, effectively replacing royal control. With
2430-540: 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

Greenland, along with the Canadian Shield , is tundra with average temperatures ranging from 10 to 20 °C (50 to 68 °F), but central Greenland is composed of a very large ice sheet. This tundra radiates throughout Canada, but its border ends near the Rocky Mountains (but still contains Alaska) and at
2700-401: Is also one of the first times that the colonies were referred to as "United States", rather than the more common United Colonies . On July 2, Congress voted for independence and published the declaration on July 4. At this point, the revolution ceased to be an internal dispute over trade and tax policies and had evolved into a civil war, since each state represented in Congress was engaged in

Present-day cultural and ethnic patterns reflect interactions between European colonists, indigenous peoples , enslaved Africans , immigrants from Europe, Asia, and descendants of these respective groups. Europe's colonization in North America led to most North Americans speaking European languages, such as English , Spanish , and French , and
4050-614: The Appalachian Mountains also avoided the cost of an expensive military occupation. The Royal Proclamation of 1763 was designed to achieve these aims by refocusing colonial expansion north into Nova Scotia and south into Florida , with the Mississippi River as the dividing line between British and Spanish possessions in America. Settlement was tightly restricted beyond the 1763 limits, and claims west of this line, including by Virginia and Massachusetts , were rescinded despite

5940-466: 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 . Later groups include
6075-481: The Iroquois for their support, while US envoys urged them to remain neutral. Aware of Native American leanings toward the British and fearing an Anglo-Indian attack from Canada, Congress authorized a second invasion in April 1775. After the defeat at the Battle of Quebec on December 31, the Americans maintained a loose blockade of the city until they retreated on May 6, 1776. A second defeat at Trois-Rivières on June 8 ended operations in Quebec. British pursuit

As a result of the development of agriculture in the south, many other cultural advances were made there. The Mayans developed
6345-469: The Second Continental Congress appointed the Committee of Five : Thomas Jefferson , John Adams , Benjamin Franklin , Roger Sherman , and Robert Livingston . The declaration was written almost exclusively by Jefferson. Identifying inhabitants of the Thirteen Colonies as "one people", the declaration simultaneously dissolved political links with Britain, while including a long list of alleged violations of "English rights" committed by George III . This
6480-464: The Second Continental Congress formalized Patriot militias into the Continental Army and appointed Washington its commander-in-chief. The British Parliament declared the colonies to be in a state of rebellion in August 1775. The stakes of the war were formalized with passage of the Lee Resolution by the Congress in Philadelphia on July 2, 1776, and the unanimous ratification of the Declaration of Independence two days later, on July 4, 1776.

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
7155-520: The colonial legislatures agreed on the boundaries but disagreed on where to set them. Many settlers resented the restrictions entirely, and enforcement required permanent garrisons along the frontier, which led to increasingly bitter disputes over who should pay for them. Although directly administered by the Crown , acting through a local governor, the colonies were largely governed by native-born property owners. While external affairs were managed by London, colonial militia were funded locally but with

Over the winter, poor conditions, supply problems and low morale resulted in 2,000 deaths, with another 3,000 unfit for duty due to lack of shoes. However, Baron Friedrich Wilhelm von Steuben took the opportunity to introduce Prussian Army drill and infantry tactics to "model companies" in each Continental Army regiment, who then instructed their home units.

This slowed Burgoyne's progress and forced him to send out large foraging expeditions; on one of these, more than 700 British troops were captured at the Battle of Bennington on August 16. St Leger moved east and besieged Fort Stanwix ; despite defeating an American relief force at the Battle of Oriskany on August 6, he was abandoned by his Indian allies and withdrew to Quebec on August 22. Now isolated and outnumbered by Gates, Burgoyne continued onto Albany rather than retreating to Fort Ticonderoga, reaching Saratoga on September 13. He asked Clinton for support while constructing defenses around
10800-638: The army of the United Colonies." He assumed command on July 3, preferring to fortify Dorchester Heights outside Boston rather than assaulting it. In early March 1776, Colonel Henry Knox arrived with heavy artillery acquired in the Capture of Fort Ticonderoga . Under cover of darkness, on March 5, Washington placed these on Dorchester Heights, from where they could fire on the town and British ships in Boston Harbor. Fearing another Bunker Hill, Howe evacuated
10935-558: The base for American naval operations. After regrouping at Halifax in Nova Scotia, Howe set sail for New York in June 1776 and began landing troops on Staten Island near the entrance to New York Harbor on July 2. The Americans rejected Howe's informal attempt to negotiate peace on July 30; Washington knew that an attack on the city was imminent and realized that he needed advance information to deal with disciplined British regular troops. On August 12, 1776, Patriot Thomas Knowlton
11070-618: The camp to a "squalid hell" and supplies were dangerously low. Burgoyne capitulated on October 17; around 6,222 soldiers, including German forces commanded by General Friedrich Adolf Riedesel , surrendered their arms before being taken to Boston, where they were to be transported to England. After securing additional supplies, Howe made another attempt on Philadelphia by landing his troops in Chesapeake Bay on August 24. He now compounded failure to support Burgoyne by missing repeated opportunities to destroy his opponent, defeating Washington at
11205-467: The city on March 17 without further loss and sailed to Halifax, Nova Scotia , while Washington moved south to New York City. Beginning in August 1775, American privateers raided towns in Nova Scotia, including Saint John , Charlottetown , and Yarmouth . In 1776, John Paul Jones and Jonathan Eddy attacked Canso and Fort Cumberland respectively. British officials in Quebec began negotiating with
11340-430: The civilian inhabitants that their lives and property would not be in any danger if they offered no resistance; they complied. Hopkins captured large stores of powder and other munitions that was so great he had to impress an extra ship in the harbor to transport the supplies back home, when he departed on March 17. A month later, after a brief skirmish with HMS Glasgow , they returned to New London, Connecticut ,
11475-458: The colonial assemblies; combined with the lack of activity by Gage, opposition to the use of foreign troops allowed the Patriots to take control of the legislatures. Support for independence was boosted by Thomas Paine 's pamphlet Common Sense , which was published on January 10, 1776, and argued for American self-government and was widely reprinted. To draft the Declaration of Independence ,
11610-569: The colonies; the amount was minor, but ignored the fact it was that very principle Americans found objectionable. In April 1772, colonialists staged the first American tax revolt in Weare , New Hampshire against the British royal authority later referred to as the Pine Tree Riot . This occurrence would later inspire the design of the Pine Tree Flag . Tensions escalated following the destruction of
11745-646: The committee shared information and built alliances through secret correspondence, as well as employing secret agents in Europe to gather intelligence, conduct undercover operations, analyze foreign publications, and initiate Patriot propaganda campaigns. Paine served as secretary, while Benjamin Franklin and Silas Deane , sent to France to recruit military engineers, were instrumental in securing French aid in Paris. The Revolutionary War included two principal campaign theaters within
11880-432: 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
12015-919: 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
12150-641: 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
12285-654: The cordillera, while the major islands of Hawaii consist of Neogene volcanics erupted over a hot spot . Central America is geologically active with volcanic eruptions and earthquakes occurring from time to time. In 1976 Guatemala was hit by a major earthquake , killing 23,000 people; Managua, the capital of Nicaragua, was devastated by earthquakes in 1931 and 1972, the last one killing about 5,000 people; three earthquakes devastated El Salvador, one in 1986 and two in 2001; one earthquake devastated northern and central Costa Rica in 2009, killing at least 34 people; in Honduras
12420-669: The cultures of the region commonly reflect Western traditions . However, relatively small parts of North America in Canada, the United States, Mexico, and Central America have indigenous populations that continue adhering to their respective pre-European colonial cultural and linguistic traditions. 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
12555-557: The driest in the U.S. Highland climates cut from north to south of the continent, where subtropical or temperate climates occur just below the tropics, as in central Mexico and Guatemala . Tropical climates appear in the island regions and in the subcontinent's bottleneck, found in countries and states bathed by the Caribbean Sea or to the south of the Gulf of Mexico and the Pacific Ocean . Precipitation patterns vary across
12690-463: The end of the Canadian Shield, near the Great Lakes . Climate west of the Cascade Range is described as being temperate weather with average precipitation 20 inches (510 millimeters). Climate in coastal California is described to be Mediterranean , with average temperatures in cities like San Francisco ranging from 57 to 70 °F (14 to 21 °C) over the course of the year. Stretching from
12825-478: The ending of the French threat in 1763, the legislatures expected less taxation, not more. At the same time, the huge debt incurred by the Seven Years' War and demands from British taxpayers for cuts in government expenditure meant Parliament expected the colonies to fund their own defense. The new taxes levied on subjects in the colonies proved highly burdensome in colonies such as North Carolina , particularly for
12960-681: The exception of Georgia , twelve colonies sent representatives to the First Continental Congress to agree on a unified response to the crisis. Many of the delegates feared that an all-out boycott would result in war and sent a Petition to the King calling for the repeal of the Intolerable Acts. However, after some debate, on September 17, 1774, Congress endorsed the Massachusetts Suffolk Resolves and on October 20 passed
13095-513: The exception of a minor skirmishing between the two armies which continued until March, Howe made no attempt to attack the Americans. The 1776 campaign demonstrated that regaining New England would be a prolonged affair, which led to a change in British strategy to isolating the north by taking control of the Hudson River , allowing them to focus on the south where Loyalist support was believed to be substantial. In December 1776, Howe wrote to
13230-548: The face of enemy fire. The successes led to predictions that the British could win within a year. The British established winter quarters in the New York City area and anticipated renewed campaigning the following spring. On the night of December 25–26, 1776, Washington crossed the Delaware River , leading a column of Continental Army troops from today's Bucks County, Pennsylvania , to today's Mercer County, New Jersey , in
13365-527: The fact that each colony argued that their boundaries extended from the Atlantic Ocean to the Pacific Ocean . The vast exchange of territory ultimately destabilized existing alliances and trade networks between settlers and Indians in the west, while it proved impossible to prevent encroachment beyond the Proclamation Line. With the exception of Virginia and others deprived of rights to western lands,
13500-544: 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
13635-900: 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°22′N 101°58′W / 43.36°N 101.97°W / 43.36; -101.97 ( Pole of Inaccessibility North America ) . Canada can be divided into roughly seven physiographic divisions: The lower 48 U.S. states can be divided into roughly eight physiographic divisions: Mexico can be divided into roughly fifteen physiographic divisions: North America
13770-473: 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 Athapascan 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
13905-460: 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
14040-475: The logistical difficulties involved and Burgoyne erroneously assumed Howe would remain on the defensive; Germain's failure to make this clear meant he opted to attack Philadelphia instead. Burgoyne set out on June 14, 1777, with a mixed force of British regulars, professional German soldiers and Canadian militia, and captured Fort Ticonderoga on July 5. As General Horatio Gates retreated, his troops blocked roads, destroyed bridges, dammed streams, and stripped
14175-498: The loss of 3,000 prisoners. The remaining American regiments on Long Island fell back four days later. General Henry Clinton wanted to pursue Washington's disorganized army, but he was first required to commit 6,000 troops to capture Newport, Rhode Island , to secure the Loyalist port. General Charles Cornwallis pursued Washington, but Howe ordered him to halt. The outlook following the defeat at Fort Washington appeared bleak for
14310-692: 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
14445-912: 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 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 / 48.167°N 100.167°W / 48.167; -100.167 , 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
14580-450: 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
14715-467: The night of August 28, Knox bombarded the British. Knowing they were up against overwhelming odds, Washington ordered the assembly of a war council on August 29; all agreed to retreat to Manhattan. Washington quickly had his troops assembled and ferried them across the East River to Manhattan on flat-bottomed freight boats without any losses in men or ordnance, leaving General Thomas Mifflin 's regiments as
14850-440: The night, Washington outmaneuvered Cornwallis, then defeated his rearguard in the Battle of Princeton the following day. The two victories helped convince the French that the Americans were worthy military allies. After his success at Princeton, Washington entered winter quarters at Morristown, New Jersey , where he remained until May and received Congressional direction to inoculate all Patriot troops against smallpox . With
14985-493: 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 , Canadian Prairies ,
15120-440: 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
15255-485: The petition to the king. Although constitutionally correct, since George could not oppose his own government, it disappointed those Americans who hoped he would mediate in the dispute, while the hostility of his language annoyed even Loyalist members of Congress. Combined with the Proclamation of Rebellion , issued on August 23 in response to the Battle at Bunker Hill , it ended hopes of a peaceful settlement. Backed by
15390-501: The poorer classes, and quickly became a source of much discontent. The 1763 to 1765 Grenville ministry instructed the Royal Navy to cease trading smuggled goods and enforce customs duties levied in American ports. The most important was the 1733 Molasses Act ; routinely ignored before 1763, it had a significant economic impact since 85% of New England rum exports were manufactured from imported molasses. These measures were followed by
15525-557: The principal instigators of the rebellion. The operation was to begin around midnight on April 19, in the hope of completing it before the American Patriots could respond. However, Paul Revere learned of the plan and notified Captain Parker , commander of the Concord militia, who prepared to resist. The first action of the war, commonly referred to as the shot heard round the world , was
15660-621: The principle of taxation by Parliament. In December 1773, a group called the Sons of Liberty disguised as Mohawk natives dumped 342 crates of tea into the Boston Harbor , an event later known as the Boston Tea Party . The British Parliament responded by passing the so-called Intolerable Acts , aimed specifically at Massachusetts, although many colonists and members of the Whig opposition considered them
15795-569: 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
15930-522: The ranges, and then establish the south boundary of each township. After each seven ranges had been completed, the Geographer was to return plats to the federal government for marketing and sale. Hutchins, along with prominent surveyors from ten states appointed by Congress, began surveying the Geographer's Line in 1785, but stopped after only a few miles because of troubles with Indians . In 1786, with protection of troops from Fort Steuben , Hutchins resumed
16065-463: The recruitment of new regiments, while allowing Catholics to enlist for the first time. Britain also signed a series of treaties with German states to supply additional troops . Within a year, it had an army of over 32,000 men in America, the largest ever sent outside Europe at the time. The employment of German soldiers against people viewed as British citizens was opposed by many in Parliament and by
16200-500: The region, and as such rainforest , monsoon , and savanna types can be found, with rains and high temperatures throughout the year. Notable North American fauna include the bison , black bear , jaguar , cougar , prairie dog , turkey , pronghorn , raccoon , coyote , and monarch butterfly . Notable plants that were domesticated in North America include tobacco , maize , squash , tomato , sunflower , blueberry , avocado , cotton , chile pepper , and vanilla . Laurentia
16335-415: The results of the formation of Pangaea was the Appalachian Mountains , which formed some 480 mya, making it among the oldest mountain ranges in the world. When Pangaea began to rift around 200 mya, North America became part of Laurasia , before it separated from Eurasia as its own continent during the mid- Cretaceous period. The Rockies and other western mountain ranges began forming around this time from
16470-542: The sovereignty and independence of the United States, bringing the American Revolutionary War to an end. The Treaties of Versailles resolved Great Britain's conflicts with France and Spain and forced Great Britain to cede Tobago , Senegal , and small territories in India to France, and Menorca , West Florida and East Florida to Spain. The French and Indian War, part of the wider global conflict known as
16605-468: The split as 40% Patriot, 40% neutral, 20% Loyalist, but with considerable regional variations. At the onset of the war, the Second Continental Congress realized defeating Britain required foreign alliances and intelligence-gathering. The Committee of Secret Correspondence was formed for "the sole purpose of corresponding with our friends in Great Britain and other parts of the world". From 1775 to 1776,
16740-576: The survey. In September 1786, Hutchins placed a stone cadastral survey marker at the west edge of the seventh range on the Geographer's Line, a spot later to be known as the Seven Ranges Terminus . After the first surveyed seven ranges had been completed some years later, the survey tract was known as the Seven Ranges , or Old Seven Ranges . The survey marker lies at the corner of four townships, three counties, and three survey tracts: The marker
16875-495: The town. Morale among his troops rapidly declined, and an unsuccessful attempt to break past Gates at the Battle of Freeman Farms on September 19 resulted in 600 British casualties. When Clinton advised he could not reach them, Burgoyne's subordinates advised retreat; a reconnaissance in force on October 7 was repulsed by Gates at the Battle of Bemis Heights , forcing them back into Saratoga with heavy losses. By October 11, all hope of escape had vanished; persistent rain reduced
17010-428: The wake of the American defeat, especially in New York state . In London, news of the victorious Long Island campaign was well received with festivities held in the capital. Public support reached a peak. Strategic deficiencies among Patriot forces were evident: Washington divided a numerically weaker army in the face of a stronger one, his inexperienced staff misread the military situation, and American troops fled in
17145-710: The war against the Americans into the Southern Colonies . Despite some initial success, British general Cornwallis was besieged by a Franco-American force in Yorktown in September and October 1781. Cornwallis was forced to surrender in October. The British wars with France and Spain continued for another two years, but fighting largely ceased in North America. In the Treaty of Paris, ratified on September 3, 1783, Great Britain acknowledged
17280-628: The war. North America North America is a continent in the Northern and Western Hemispheres . North America 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 west and south by the Pacific Ocean . The region includes the Bahamas , Bermuda , Canada , the Caribbean , Central America , Clipperton Island , Greenland , Mexico , Saint Pierre and Miquelon , Turks and Caicos Islands , and
17415-540: Was called the Council of the Indies . The United Nations and its statistics division recognize North America as including three regions: Northern America, Central America , and the Caribbean . "Northern America" is a distinct term from "North America", excluding Central America, which itself may or may not include Mexico . In the limited context of regional trade agreements, the term is used to reference three nations: Canada,
17550-458: Was estimated as over 592 million people in 23 independent states , or about 7.5% of the world's population. In human geography , the terms "North America" and "North American" can refer to Canada, the United States, Mexico, and Greenland or, alternatively, Canada, Greenland and the US (Mexico being classified as part of Latin America ) or simply Canada and the US (Greenland being classified as either Arctic or European (due to its political status as
17685-568: 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
17820-420: Was initially blocked by American naval vessels on Lake Champlain until victory at Valcour Island on October 11 forced the Americans to withdraw to Fort Ticonderoga , while in December an uprising in Nova Scotia sponsored by Massachusetts was defeated at Fort Cumberland . These failures impacted public support for the Patriot cause, and aggressive anti-Loyalist policies in the New England colonies alienated
17955-414: Was ordered to form an elite group for reconnaissance and secret missions. Knowlton's Rangers , which included Nathan Hale , became the Army's first intelligence unit. When Washington was driven off Long Island , he soon realized that he would need to professionalize military intelligence. With aid from Benjamin Tallmadge , Washington launched the six-man Culper spy ring . The efforts of Washington and
18090-411: Was poised to capture Philadelphia , the Continental Congress fled to Baltimore . In October 1777, a separate northern British force under the command of John Burgoyne was forced to surrender at Saratoga in an American victory that proved crucial in convincing France and Spain that an independent United States was a viable possibility. France signed a commercial agreement with the rebels, followed by
18225-416: Was the first European to suggest that the Americas represented a landmass not then known 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
