Civil Rights Act of 1866
The Civil Rights Act of 1866, , enacted April 9, 1866, 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. This legislation was passed by Congress in 1865 and vetoed by U.S. President Andrew Johnson. In April 1866 Congress again passed the bill to support the Thirteenth Amendment. Johnson again vetoed it, but a two-thirds majority in each chamber overcame the veto to become law without presidential signature.
Thirteenth Amendment to the United States Constitution
As its first enforcement legislation, Congress passed the Civil Rights Act of 1866, guaranteeing black Americans citizenship and equal protection of the law, though not the right to vote. The amendment was also used as authorizing several Freedmen's Bureau bills. President Andrew Johnson vetoed these bills, but Congress overrode his vetoes to pass the Civil Rights Act and the Second Freedmen's Bureau Bill.
