How were literacy tests used to keep black men from voting after the civil war ything?

After the Civil War, literacy tests were implemented in many Southern states as a means to disenfranchise Black voters. These tests often included complex questions and were administered subjectively, allowing white registrars to arbitrarily pass or fail applicants based on race. The goal was to create barriers that would effectively prevent Black men, who had been systematically denied quality education, from exercising their right to vote. This practice, along with other discriminatory measures like poll taxes and understanding clauses, aimed to maintain white supremacy in the political system.
