Which amendment to the United States Constitution recognized women’s right to vote nationwide?

The Nineteenth Amendment recognized women’s constitutional right to vote nationwide.

Congress approved the amendment in June 1919, and Tennessee became the 36th state to ratify it on August 18, 1920. The required three-fourths of the states had therefore approved the amendment, which was certified on August 26, 1920.

Its text prohibits the United States and the states from denying or abridging the right to vote on account of sex. The amendment capped decades of organizing, petitioning, marches, lawsuits, and civil disobedience by the woman suffrage movement.

Ratification did not immediately give every woman equal access to the ballot. Many Black women in the South continued to face poll taxes, literacy tests, intimidation, and discriminatory registration practices. Native American women and other groups also encountered separate legal barriers to citizenship and voting.
