Which amendment abolished poll taxes in federal elections?

The 24th Amendment abolished poll taxes in federal elections, making it illegal to require payment of a tax as a prerequisite for voting in federal elections. This amendment was ratified in 1964 and was a significant step in the fight against voter suppression, particularly aimed at ensuring that economic barriers could not disenfranchise citizens, especially in the context of the civil rights movement.

Poll taxes were often used to restrict voting rights for African Americans and poor people, as they could not afford the tax and therefore were effectively excluded from the electoral process. The passage of the 24th Amendment helped to eliminate this discriminatory practice in federal elections, promoting a more equitable voting system.

Other amendments listed have different focuses: the 15th Amendment prohibits denying the right to vote based on race, the 19th Amendment grants women the right to vote, and the 26th Amendment lowers the voting age to 18. While all of these amendments contributed to expanding voting rights in different ways, it is the 24th Amendment specifically that targets the issue of poll taxes in federal elections.
