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.
Civil rights movement
On June 21, 1964, three civil rights workers disappeared: James Chaney, a young black Mississippian and plasterer's apprentice; and two Jewish activists, Andrew Goodman, a Queens College anthropology student; and Michael Schwerner, a CORE organizer from Manhattan's Lower East Side. They were found weeks later, murdered by conspirators who turned out to be local members of the Klan, some of them members of the Neshoba County sheriff's department. This outraged the public, leading the U.S. Justice Department along with the FBI (the latter which had previously avoided dealing with the issue of segregation and persecution of blacks) to take action. The outrage over these murders helped lead to the passage of the Civil Rights Act of 1964 and the Voting Rights Act of 1965.
