Indigenous peoples have inhabited the Americas for thousands of years. Beginning in 1607, British colonization led to the establishment of the Thirteen Colonies in what is now the Eastern United States. They clashed with the British Crown over taxation and political representation, which led to the American Revolution and the ensuing Revolutionary War. The United States declared independence on July 4, 1776, becoming the first nation-state founded on Enlightenment principles of unalienable natural rights, consent of the governed, and republicanism. The country began expanding across North America, spanning the continent by 1848. Sectional division over slavery led to the secession of the Confederate States of America, which fought the remaining states of the Union during the American Civil War (1861–1865). With the Union's victory and preservation, slavery was abolished nationally. By 1900, the United States had established itself as a great power, becoming the world's largest economy. After Japan's attack on Pearl Harbor in December 1941, the U.S. entered World War II on the side of the Allies. The aftermath of the war left the United States and the Soviet Union as the world's two superpowers and led to the Cold War, during which both countries engaged in a struggle for ideological dominance and international influence but avoided direct military conflict. During the Space Race, the United States landed the first humans on the Moon. Following the Soviet Union's collapse and the end of the Cold War, the United States emerged as the world's sole superpower.

The United States government is a federal presidential constitutional republic and liberal democracy with three separate branches of government: executive, legislative, and judicial. It has a bicameral national legislature composed of the House of Representatives, a lower house based on population; and the Senate, an upper house based on equal representation for each state. Many policy issues are decentralized at a state or local level, with widely differing laws by jurisdiction. The U.S. ranks very highly in international measures of quality of life, income and wealth, productivity, economic competitiveness, human rights, innovation, and education.

Highly developed, the U.S. possesses the largest amount of wealth of any country. The American economy accounts for over a quarter of global GDP and is the world's largest by nominal GDP. The U.S. is the world's largest importer and second-largest exporter. It is a founding member of the United Nations, the World Bank, the International Monetary Fund, the Organization of American States, NATO and WHO, and is a permanent member of the United Nations Security Council. The U.S. is a recognized nuclear-weapon state and wields considerable global influence as the world's foremost political, cultural, economic, military, and scientific power.
