The Civil Rights Act of 1866 (14 Stat. 27–30, enacted April 9, 1866, reenacted 1870) was the first United States federal law to define citizenship and affirm that all citizens are equally protected by the law. It was mainly intended, in the wake of the American Civil War, to protect the civil rights of persons of African descent born in or brought to the United States. John Bingham and other congressmen argued that Congress did not yet have sufficient constitutional power to enact this law. Following passage of the Fourteenth Amendment in 1868, Congress ratified the 1866 Act in 1870.
