The primary reason Southern states used poll taxes, literacy tests, and grandfather clauses as Reconstruction came to an end was to keep African Americans from voting. These measures were implemented as part of a broader effort to disenfranchise black voters and maintain white supremacy in the South. Additionally, poll taxes and literacy tests were used to also keep poor white Southerners from voting, as they were often unable to pay the tax or pass the literacy test.
