What were three ways southerners tried to disrupt african americans from voting?

Poll taxes, literacy tests, violence/terrorism, and economic intimidation (For example, telling a black sharecropper that you won't sell them seed if they vote.)

The tests were impossible to pass, regardless of color. The poll taxes were obviously an economic way to prevent blacks from voting. I'm sure there were other ways as well. I know they would also threaten violence to families, children, and the voters if they even attempted to vote.
