(CNN) -- The Civil Rights Act in 1964 is considered the nation's most important civil rights legislation since Reconstruction (1865-1877) as it prohibited discrimination on the basis of race, color, religion, sex or national origin. Following that law, President Lyndon B. Johnson signed landmark civil rights bills including the 1965 Voting Rights Act and the 1968 Fair Housing Act.
"Each year, from 1945 until 1957, Congress considered and failed to pass a civil rights bill. Congress finally passed limited Civil Rights Acts in 1957 and 1960, but they offered only moderate gains. As a result of the 1957 Act, the United States Commission on Civil Rights was formed to investigate, report on, and make recommendations to the President concerning civil rights issues." - National Park Service
