U.S. history 101

The history of the United States begins with British colonies in the 1600s and leads to independence after the American Revolution (1776). The Constitution established the framework for a democratic government. Throughout the 19th century, the U.S. expanded westward, fought the Civil War over slavery, and underwent Reconstruction. The 20th century brought industrial growth, world wars, the Great Depression, and the Civil Rights Movement. In recent decades, America has become a global superpower, facing modern challenges like terrorism, technology, and political division.
