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.
Thomas B. Curtis
The Civil Rights Act of 1964 originated in Curtis' office in 1962, and it was mainly Republican pressure from Curtis and his fellow Republican Judiciary Committee member William McCulloch of Ohio that forced John F. Kennedy to make his first, hesitant message on civil rights in April 1963. Curtis' defense of civil rights was rooted partly in the Lincoln tradition of the GOP, but more simply in the belief that civil rights were at the base of the American philosophy of government and Judeo-Christian morality and that their defense was "the most fundamental issue that confronts any government at any time," as he wrote in 1952.
