The Voting Rights Act of 1965 is a landmark piece of federal legislation in the United States that aimed to eliminate barriers preventing African Americans from exercising their right to vote. It was enacted to enforce the voting rights guaranteed by the 14th and 15th Amendments, particularly addressing issues like literacy tests and discriminatory practices that were prevalent in many Southern states. This act is a significant achievement of the civil rights movement and played a vital role in ensuring equal protection under the law for all citizens, regardless of race.
