The United States of America (USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major self-governing territories, 326 Indian reservations, and some minor possessions. With a population of over 331 million people, it is the world's third-most populous country. The capital city is Washington, D.C., and the largest city by population is New York City.


The name "America" is derived from the Latin version of the name of Italian explorer Amerigo Vespucci. The suffix "-rica" means "land" or "place of." The United States was originally a collection of British colonies along the Atlantic coast, which declared independence from Great Britain in 1776 and formed a union of states under the United States Constitution in 1789.


The history of the United States dates back thousands of years to the arrival of Native American tribes. The first European settlement in what is now the United States was established in 1565 by the Spanish in St. Augustine, Florida. The English Pilgrims arrived in 1620 and established the Plymouth Colony, which became the second successful English settlement after Jamestown, Virginia.

Over the centuries, European powers, including the Spanish, French, and Dutch, established colonies and trading posts in various parts of North America. The Thirteen Colonies, primarily settled by the British, declared independence from Great Britain in 1776, leading to the American Revolutionary War. The war ended in 1783 with the recognition of the United States as an independent nation.

The United States expanded westward throughout the 19th century, acquiring new territories, and eventually reaching the Pacific Ocean. The country experienced significant industrialization and economic growth during the late 19th and early 20th centuries. It played a major role in both World Wars and emerged as a global superpower in the aftermath of World War II.
