The American Revolutionary War, also known as the Revolutionary War or American War of Independence, was an armed conflict that was part of the broader American Revolution, in which American Patriot forces organized as the Continental Army and commanded by George Washington defeated the British Army. The conflict was fought in North America, the Caribbean, and the Atlantic Ocean. The war ended with the Treaty of Paris (1783), which resulted in Great Britain ultimately recognizing the independence and sovereignty of the United States.
The American Revolution was a rebellion and political movement in the Thirteen Colonies which peaked when colonists initiated an ultimately successful war for independence against the Kingdom of Great Britain. Leaders of the American Revolution were colonial separatist leaders who originally sought more autonomy as British subjects, but later assembled to support the Revolutionary War, which ended British colonial rule over the colonies, establishing their independence as the United States of America in July 1776.
African Americans or Black Americans, formerly also called Afro-Americans, are an American racial or ethnic group consisting of people who self-identity as having origins from Sub-Saharan Africa. They constitute the country's second largest racial group after White Americans. The primary understanding of the term "African American" denotes a community of people descended from enslaved Africans, who were brought over during the colonial era of the United States. As such, it typically does not refer to Americans who have partial or full origins in any of the North African ethnic groups, as they are instead broadly understood to be Arab or Middle Eastern, although they were historically classified as White in United States census data.
Christopher Columbus was an Italian explorer and navigator from the Republic of Genoa who completed four Spanish-based voyages across the Atlantic Ocean sponsored by the Catholic Monarchs, opening the way for the widespread European exploration and colonization of the Americas. His expeditions were the first known European contact with the Caribbean and Central and South 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 the United States.
Native Americans are the Indigenous peoples of the United States of America, particularly of the lower 48 states and Alaska. They may also include any Americans whose origins lie in any of the indigenous peoples of North or South America. The United States Census Bureau publishes data about "American Indians and Alaska Natives", whom it defines as anyone "having origins in any of the original peoples of North and South America ... and who maintains tribal affiliation or community attachment". The census does not, however, enumerate "Native Americans" as such, noting that the latter term can encompass a broader set of groups, e.g. Native Hawaiians, which it tabulates separately.

South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a considerably smaller portion in the Northern Hemisphere. It can also be described as the southern subregion of the Americas.
The Americas, sometimes collectively called America, known initially as India Nova, are a landmass comprising the totality of North America and South America. When viewed as a single continent, the Americas or America is the 2nd largest continent right after Asia, and is the 3rd largest continent by population. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World.
The War of 1812 was fought by the United States and its allies against the United Kingdom and its allies in North America. It began when the United States declared war on Britain on 18 June 1812. Although peace terms were agreed upon in the December 1814 Treaty of Ghent, the war did not officially end until the peace treaty was ratified by the United States Congress on 17 February 1815.
The Thirteen Colonies were a group of British colonies on the Atlantic coast of North America during the 17th and 18th centuries. Grievances against the imperial government led the 13 colonies to begin uniting in 1774, and expelling British officials by 1775. Assembled at the Second Continental Congress in Philadelphia, after armed conflict had broken out in April, they appointed George Washington as commander-in-chief of the Continental Army to fight the American Revolutionary War. In 1776, Congress adopted the Declaration of Independence as the United States of America and, asserting its sovereignty, the United States allied with Britain's enemy France. Defeating British armies with its French ally, the former Thirteen Colonies had its sovereignty recognized by Britain in the Treaty of Paris in 1783.
Northern America is the northernmost subregion of North America as well as the northernmost region in the Americas. The boundaries may be drawn significantly differently depending on the source of the definition. In one definition, it lies directly north of Middle America. Northern America's land frontier with the rest of North America then coincides with the Mexico–United States border. Geopolitically, according to the United Nations' scheme of geographical regions and subregions, Northern America consists of Bermuda, Canada, Greenland, Saint Pierre and Miquelon and the United States.
The United States of America (USA), commonly known as the United States (U.S.) or America, is a country primarily located in North America. It is a federal union of 50 states and a federal capital district, Washington, D.C. The 48 contiguous states border Canada to the north and Mexico to the south, with the states of Alaska to the northwest and the archipelagic Hawaii in the Pacific Ocean. The United States also asserts sovereignty over five major island territories and various uninhabited islands. The country has the world's third-largest land area, largest exclusive economic zone, and third-largest population, exceeding 334 million. Its three largest metropolitan areas are New York, Los Angeles, and Chicago, and its three most populous states are California, Texas, and Florida.
Thanksgiving is a national holiday celebrated on various dates in October and November in the United States, Canada, Saint Lucia, Liberia, and unofficially in countries like Brazil, Germany and the Philippines. It is also observed in the Dutch town of Leiden and the Australian territory of Norfolk Island. It began as a day of giving thanks for the blessings of the harvest and of the preceding year. Various similarly named harvest festival holidays occur throughout the world during autumn. Although Thanksgiving has historical roots in religious and cultural traditions, it has long been celebrated as a secular holiday as well.
American Samoa is an unincorporated territory of the United States located in the Polynesia region of the South Pacific Ocean. Centered on 14.3°S 170.7°W, it is 40 miles (64 km) southeast of the island country of Samoa, east of the International Date Line and the Wallis and Futuna Islands, west of the Cook Islands, north of Tonga, and some 310 miles (500 km) south of Tokelau. American Samoa is the southernmost territory of the United States, situated 2,200 miles (3,500 km) southwest of the U.S. state of Hawaii, and one of two U.S. territories south of the Equator, along with the uninhabited Jarvis Island.
Bakevelliidae is an extinct family of prehistoric bivalves that lived from the Late Mississippian until the Middle Eocene. Bakevelliidae species are found worldwide, excluding Antarctica. Living a stationary life attached to substrate in marine and brackish environments, they formed shells of an aragonite composition with a low amount of magnesium calcite. The family was named by William King in 1850. At least one genus in the family, Hoernesia, has a notably twisted commissure join.
