Which amendment to the U.S. Constitution granted women the right to vote?

The Nineteenth Amendment to the U.S. Constitution is the amendment that granted women the right to vote. Ratified in 1920, it specifically states that the right to vote cannot be denied or abridged on the basis of sex. This amendment marked a significant milestone in the women's suffrage movement, which sought to secure equal voting rights for women across the United States.

Understanding the context of this amendment highlights its historical significance and the long struggle for women's rights. Prior to the Nineteenth Amendment, various states had passed laws granting women limited voting rights, but these were often inconsistent and varied by location. The Nineteenth Amendment provided a constitutional guarantee that helped to ensure uniformity in voting rights for women nationwide.

The other amendments listed do not pertain to women's voting rights. The Fifteenth Amendment addresses voting rights regardless of race but does not mention sex. The Twenty-first Amendment repealed Prohibition, while the Twenty-fourth Amendment eliminated poll taxes in federal elections, neither of which relates directly to women's suffrage. Therefore, the Nineteenth Amendment stands out as the pivotal change that solidified women's right to participate in the electoral process.
