August 6 - Washington, DC - In what is seen by many as the biggest achievement of the Civil Rights Movement, President Johnson signed the Voting Rights Act which banned laws that were enacted to keep Black Americans from voting and allowed the federal government to send registrars to states that had a history of discriminating against black voters.   The Act is later upheld by the Supreme Court.
