History

The land was inhabited for millennia by diverse Indigenous peoples before European colonization began in the 16th century, led by powers like Great Britain, Spain, and France. Thirteen British colonies declared independence in 1776, winning sovereignty after the American Revolutionary War. The Constitutional Convention of 1787 established the current framework of government. The 19th century saw westward expansion, the forced removal of Native Americans, and the Civil War, which ended slavery and preserved the Union. The 20th century was marked by participation in both World War I and World War II, the Cold War rivalry with the Soviet Union, the Civil Rights Movement, and significant technological achievements like the Apollo program.
