The Civil Rights Act of 1866 is a federal law in the United States declaring that everyone born in the U.S. and not subject to any foreign power is a citizen, without regard to race, color, or previous condition of slavery or involuntary servitude. As citizens they could make and enforce contracts, sue and be sued, give evidence in court, and inherit, purchase, lease, sell, hold, and convey real and personal property. Persons who denied these rights to former slaves were guilty of a misdemeanor and upon conviction faced a fine not exceeding $1,000, or imprisonment not exceeding one year, or both. The activities of organizations such as the Ku Klux Klan undermined the workings of this act and it failed to guarantee the civil rights of African Americans. This statute does not cover visitors, diplomats, and Native Americans in the United States on reservations. It was aimed at the Freedmen (freed slaves) and was a major policy during Reconstruction. It was vetoed by President Andrew Johnson then passed over his veto by Radical Republicans in Congress.
