Final answer:
The Voting Rights Act of 1965 effectively enforced the Fifteenth Amendment, which was aimed at securing voting rights for racial minorities by giving the federal government powers to oversee and intervene in state election processes.
Step-by-step explanation:
The Voting Rights Act of 1965 finally made the Fifteenth Amendment an effective part of the Constitution. This act was designed to enforce the voting rights guaranteed by the Fourteenth and Fifteenth Amendments to the United States Constitution, particularly securing voting rights for racial minorities.
The act's enforcement mechanisms allowed the federal government to oversee elections in areas with a history of discrimination and abolished barriers such as literacy tests. Moreover, states found in violation of the act were required to obtain federal approval before changing election laws.
The Voting Rights Act is recognized as one of the most powerful pieces of civil rights legislation in American history, significantly advancing the assurance of suffrage for all citizens regardless of race.
