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.

Passing the civil rights bill in the House required getting it through the Rules Committee, which had been holding it up in an attempt to kill it. Johnson decided on a campaign to use a discharge petition to force it onto the House floor. Facing a growing threat that they would be bypassed, the House rules committee approved the bill and moved it to the floor of the full House, which passed it shortly thereafter by a vote of 290–110. In the Senate, since the tax bill had passed three days earlier, the anti-civil-rights senators were left with the filibuster as their only remaining tool. Overcoming the filibuster required the support of over twenty Republicans, who were growing less supportive due to the fact that their party was about to nominate for president a candidate who opposed the bill. According to Caro, it was ultimately Johnson's ability to convince Republican leader Everett Dirksen to support the bill that amassed the necessary Republican votes to overcome the filibuster in March 1964; after 75 hours of debate, the bill passed the Senate by a vote of 71–29. Johnson signed the fortified Civil Rights Act of 1964 into law on July 2. Legend has it that the evening after signing the bill, Johnson told an aide, "I think we just delivered the South to the Republican party for a long time to come", anticipating a coming backlash from Southern whites against Johnson's Democratic Party.
