The Twenty-Fourth Amendment to the United States Constitution, ratified in 1964, prohibits the use of poll taxes in federal elections. Poll taxes were fees that individuals had to pay in order to vote, which often disenfranchised low-income citizens and marginalized groups. This amendment aimed to ensure that voting rights were accessible to all citizens, regardless of their financial status. The amendment was a significant step in the civil rights movement, as it helped to eliminate barriers that prevented many Americans from exercising their right to vote. It reinforced the principle that voting is a fundamental right, protected from discriminatory practices like poll taxes.
