What Tax meant to keep someone from voting?

A poll tax was a fee that individuals were required to pay in order to vote. This practice was often used in the United States, particularly in Southern states, as a means to disenfranchise poor and minority voters, especially African Americans. Poll taxes effectively limited access to the electoral process, as many individuals could not afford to pay the tax. The practice was eventually deemed unconstitutional by the 24th Amendment in 1964, which prohibited poll taxes in federal elections.
