Paleo-Indians first migrated from North Asia to North America at least 15,000 years ago, and formed various civilizations. Spanish colonization established Spanish Florida in 1513, the first European colony in what is now the continental United States. British colonization followed with the 1607 settlement of Virginia, the first of the Thirteen Colonies. Enslavement of Africans was practiced in every colony by 1770 and supplied most of the labor for the Southern Colonies' plantation economy. Clashes with the British Crown began as a civil protest over the illegality of taxation without representation in Parliament and the denial of other English rights. They evolved into the American Revolution, which led to the Declaration of Independence and a society based on universal rights. Victory in the 1775–1783 Revolutionary War brought international recognition of U.S. sovereignty and fueled westward expansion, further dispossessing native inhabitants. As more states were admitted into the Union, a North–South division over slavery led 11 Southern states to attempt to secede and join together as the Confederate States of America, which fought against the Union of remaining states in the American Civil War of 1861–1865. After the United States' victory and reunification, slavery was abolished nationally. By 1900, the country had established itself as a great power, a status solidified after its involvement in World War I. Following Japan's attack on Pearl Harbor in 1941, the U.S. entered World War II. Its aftermath left the U.S. and the Soviet Union as rival superpowers, competing for ideological dominance and international influence during the Cold War. The collapse of the Soviet Union in 1991 ended the Cold War, leaving the U.S. as the world's sole superpower. After the terror attacks of September 11, 2001, the U.S. launched the war on terror, invading Afghanistan and Iraq. It has carried out numerous foreign interventions since then. - Source: Wikipedia
