United States

The United States of America (USA), also known as the United States (U.S.) or America, is a country primarily located in North America. It is a federal republic consisting 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 semi-exclave of Alaska in the northwest and the archipelago of Hawaii in the Pacific Ocean. The United States also asserts sovereignty over five major island territories and various uninhabited islands in Oceania and the Caribbean. It is a megadiverse country, with the world's third-largest land area and third-largest population, exceeding 341 million. Paleo-Indians first migrated from North Asia to North America at least 15,000 years ago, and formed various civilizations. European discovery of the Americas began in 1492, and British colonization followed with the 1607 settlement of Virginia, the first of the Thirteen Colonies. The American Enlightenment that spread throughout the colonies in the 18th century valued republicanism and liberalism. Clashes with the British Crown over taxation without parliamentary representation and the denial of other English rights evolved into the American Revolution, which led to the July 2, 1776, Lee Resolution formally declaring independence from Great Britain. This was followed two days later, on the Fourth of July, by the adoption and public release of the Declaration of Independence. Victory in the 1775–1783 Revolutionary
