Some of these methods included poll taxes, which many could not afford, literacy tests, that many could not pass, and grandfather clauses, which stated that one can only vote if their grandfather voted. This changed  with the passing of the Voting Rights Act of 1965, which outlawed these racially discriminatory practices and required government supervision for states that had less than 50 percent of non-White citizens registered to vote.
The voting procedures in place at the time included poll taxes that were financially burdensome for many, literacy tests that were difficult to overcome, and grandfather clauses that effectively barred many from participating. However, the Voting Rights Act of 1965 brought about a significant shift by prohibiting these discriminatory practices and requiring government oversight in states with low voter registration among non-Whites.
