The Voting Rights Act of 1965 brought a immense change:
Still, the Voting Rights Act gave African-American voters the legal means to challenge voting restrictions and vastly improved voter turnout. In Mississippi alone, voter turnout among blacks increased from 6 percent in 1964 to 59 percent in 1969.
Since its passage, the Voting Rights Act has been amended to include such features as the protection of voting rights for non-English speaking American citizens.
