Poll taxes were fees required to be paid in order to vote, often used as a tool to disenfranchise low-income individuals, particularly African Americans and poor whites in the South. These taxes emerged after Reconstruction as a means to maintain white supremacy and limit the political power of newly freed slaves. By imposing financial barriers, poll taxes became a significant part of the systematic efforts to undermine the rights gained during the Reconstruction era and shaped the political landscape of the New South.
