What constitutional amendment prohibited the requirement of a poll tax or any other tax for the privilege to vote?

The Twenty-fourth Amendment to the United States Constitution specifically prohibits the imposition of poll taxes in federal elections. Ratified in 1964, this amendment was a significant step in the civil rights movement, aimed at eliminating a financial barrier that was used to restrict voting rights, particularly for African Americans and low-income individuals. By ensuring that no taxes would be required for the privilege of voting, the Twenty-fourth Amendment helped to make the electoral process more accessible and equitable.

The other amendments listed do not pertain to voting and taxation. The Twenty-first Amendment primarily addresses the repeal of Prohibition, the Twenty-second Amendment limits presidential terms, and the Twenty-sixth Amendment grants voting rights to citizens who are 18 years of age or older. Each of these amendments addresses different aspects of American governance and civil rights, distinct from the specific issue of poll taxes addressed by the Twenty-fourth Amendment.
