Which amendment abolished the poll tax in federal elections?

The 24th Amendment to the United States Constitution is significant because it prohibits the imposition of a poll tax in federal elections. Ratified in 1964, this amendment emerged from the civil rights movement, which sought to eliminate barriers to voting that disproportionately affected minority groups and low-income individuals. By abolishing the poll tax, the amendment aimed to ensure that citizens would not have to pay a fee to vote, thus enhancing access to the electoral process.

The introduction of a poll tax had historically been used in some states as a means of disenfranchising poor and minority voters, particularly in the South. The 24th Amendment addressed these injustices by reinforcing the principle that voting should be a right accessible to all eligible citizens, irrespective of their economic status. This change was a significant step in the progression toward equal voting rights in the United States. The other amendments mentioned pertain to different issues: the 22nd Amendment limits presidential terms, the 26th Amendment lowers the voting age to 18, and the 21st Amendment repeals Prohibition.
