Harper v. Virginia Board of Elections, 383 U.S. 663 (1966), was a landmark case decided by the Supreme Court of the United States that declared that Virginia's poll tax, which required citizens to pay a fee in order to vote, was unconstitutional. The Court held that the poll tax violated the Equal Protection Clause of the Fourteenth Amendment because it imposed an unjustified financial burden on citizens and effectively denied the right to vote to those who could not afford to pay it. The decision in Harper v. Virginia had far-reaching implications, striking down similar poll taxes in other states and helping to expand access to the ballot for all Americans, regardless of their financial status.
