Constitution - 24th Amendment

Although the 15th amendment granted African Americans the right to vote, many were still prevented from voting by other means, such as literacy tests and poll taxes. Throughout the 20th century, civil rights organizations and leaders continued to pressure government officials to protect equal opportunities and civil liberties for African American citizens. In 1964, the 24th amendment was ratified, which prevented both national and state government officials from denying the right to vote based on the payment of a poll tax.
