franchise
In politics, the right to vote. The Constitution left the determination of the qualifications of voters to the states. In the late eighteenth and early nineteenth century, states usually restricted the franchise to white men who owned specified amounts of property. Gradually, poll taxes were substituted for property requirements. Before the Civil War, the voting rights of blacks were severely restricted, but the Fifteenth Amendment to the Constitution, declared ratified in 1870, prohibited states from abridging the right to vote on the basis of race. Nevertheless, southern states used a variety of legal ploys to restrict black voting until passage of the Voting Rights Act of 1965. Women were not guaranteed the right to vote in federal elections until ratification of the Nineteenth Amendment in 1920. In 1971 the Twenty-sixth Amendment lowered the voting age from twenty-one to eighteen. (Seesuffrageandsuffragette.)
Losing the right to vote, called disfranchisement, is most commonly caused by failing to reregister, a procedure that is required every time a person changes residence.
