This act was signed into law on August 6, 1965, by President Lyndon Johnson. It outlawed the discriminatory voting practices adopted in many southern states after the Civil War, including literacy tests as a prerequisite to voting.
Because the Voting Rights Act of 1965 was the most significant statutory change in the relationship between the Federal and state governments in the area of voting since the Reconstruction period following the Civil War, it was immediately challenged in the courts. Between 1965 and 1969, the Supreme Court issued several key decisions upholding the constitutionality of Section 5 and affirming the broad range of voting practices for which preclearance was required.
The law had an immediate impact. By the end of 1965, a quarter of a million new black voters had been registered, one-third by Federal examiners. By the end of 1966, only 4 out of the 13 southern states had fewer than 50 percent of African Americans registered to vote. The Voting Rights Act of 1965 was readopted and strengthened in 1970, 1975, and 1982.
