The United States of America, also known as the United States, the U.S., the U.S.A., the States, and America, is a country in North America. A federal constitutional republic, the United States shares land borders with Canada and Mexico, and extends from the Atlantic Ocean to the Pacific Ocean. Its capital is Washington, D.C.

The present-day United States has been inhabited for at least 15,000 years by Native Americans. After 16th-century European exploration, the British established colonies in the eastern portion of the continent in the 17th century. On July 4, 1776, at war with Britain over who would govern, thirteen of these colonies declared their independence; in 1783, the war ended in British acceptance of the new nation. Since then, the country has expanded greatly through territorial acquisitions: it now consists of 50 states, a federal district, and a number of overseas territories.

At over 3.7 million square miles (over 9.1 million km²), the U.S. is the third largest country by area. Home to nearly 300 million people, it is the world's third most populous nation.

The United States has maintained a stable liberal democratic political system since it adopted its constitution on September 17, 1787. American military and economic stature increased throughout the 20th century; with the collapse of the Soviet Union at the end of the Cold War, the nation emerged as the world's sole superpower.
