List 3 obstacles that were used to keep African Americans from voting in the south?

Three significant obstacles that were used to suppress African American voting in the South included literacy tests, which often had confusing questions designed to disenfranchise Black voters; poll taxes, which required payment to vote and disproportionately affected low-income individuals; and understanding clauses, where registrars could arbitrarily determine whether a voter understood the Constitution or other documents. These discriminatory practices were aimed at maintaining white supremacy and political control in the region.
