The Civil Rights Act of 1866 made the newly emancipated black Americans of the South into U.S. citizens and protected their civil rights. It was passed by the Senate and the House on March 14, 1866. Later that month, President Andrew Johnson vetoed the Civil Rights Act, on the grounds that “this law establishes for the security of the colored race safeguards which go infinitely beyond any that the General Government have ever provided for the white race.”
