8. Fifteenth Amendment, 1870
The Fifteenth Amendment prohibits states from denying the right to vote on the grounds of “race, color, or previous condition of servitude.” The amendment was meant to protect citizens’ voting rights, but some states, including the former Confederate states, still found ways to disqualify voters based on race and economic status. These states adopted new state constitutions and passed laws, known as Jim Crow laws, that created obstacles, like poll taxes and literary tests, to prevent citizens from registering to vote. The laws were usually written to seem non-racial but were applied in ways that selectively suppressed certain voters. At the time, the Supreme Court typically upheld the states’ right to determine a voter’s eligibility, even if it resulted in discrimination. It wasn’t until the passage of the Voting Rights Act of 1965 that these laws were ruled unconstitutional.
