African Americans in Alabama had been essentially disenfranchised by the 1901 state constitution, which required payment of a poll tax and qualification by a literacy test in order to register to vote. Discriminatory in practice as administered by white officials, this system excluded most blacks from the state's political system for decades in the 20th century before Congress passed the Voting Rights Act of 1965. Since then, African Americans were able finally to register and vote in the county and state for the first time since the late 19th century.
