Williams v. Mississippi, 170 U.S. 213 (1898) is a United States Supreme Court case that reviewed provisions of the state constitution that set requirements for voter registration. The Supreme Court did not find discrimination in the state's requirements for voters to pass a literacy test and pay poll taxes, as these were applied to all voters. In practice, the subjective nature of literacy approval by white registrars worked to drastically decrease and essentially disfranchise African American voters.
