Which amendment abolished poll taxes in federal elections?

The Twenty-fourth Amendment abolished poll taxes in federal elections. Ratified in 1964, this amendment was a significant step in the civil rights movement, aimed at removing barriers that were used to disenfranchise voters, particularly African Americans and poor people. Poll taxes required voters to pay a fee to participate in elections, which many could not afford. This amendment made it unconstitutional to impose such a tax in federal elections, thereby expanding access to the electoral process and reinforcing the principle of equal voting rights.

The other amendments mentioned address different issues: the Fifteenth Amendment prohibits the denial of voting rights based on race, the Nineteenth Amendment grants women the right to vote, and the Twenty-second Amendment limits the number of terms a president can serve. Each of these plays a crucial role in the broader context of voting rights but does not specifically address the issue of poll taxes.
