Several laws have been called the Civil Rights Act
The United States Civil Rights Act of 1866 aimed to buttress Civil Rights Laws to protect freedmen and to grant full citizenship to those born on US soil except Indianss. While President Andrew Johnson vetoed the bill, the veto was overridden by Congress.
The Civil Rights Act of 1957 established a Civil Rights Commission (CRC) to protect individuals rights to Equal Protection Under the Law and permitted courts to grant injunctions in support of the CRC.
The Civil Rights Act of 1964 (CRA'64) in the United States was landmark legislation. The original purpose of the Bill was to protect black men from job discrimination, but at the last minute in an attempt to kill the bill, it was expanded to include protection for women. As a result it formed the political impetus for feminism. CRA'64 transformed American society. It prohibited discrimination in public and governmental facilities. See Civil Rights Act of 1964 for more details.
