The United States of America (USA) is one of the world’s most influential nations, known for its economic power, military strength, technological innovation, and democratic institutions. Located in North America, the United States was founded in 1776 and has grown from a collection of thirteen British colonies into a global superpower. Its history is marked by revolution, expansion, civil conflict, industrial growth, and a continuing struggle to fulfill its founding ideals of liberty and equality.
Early America Before European Settlement
Long before Europeans arrived, North America was home to millions of Indigenous peoples belonging to hundreds of nations and cultures. These included civilizations such as the Mississippian culture, the Pueblo peoples of the Southwest, and the Iroquois Confederacy in the Northeast.

Over time, thirteen British colonies emerged. The colonies developed representative governments and strong local identities while remaining under British rule.
