Which amendment granted women the right to vote in the United States?

The 19th Amendment granted women the right to vote in the United States, marking a significant milestone in the women's suffrage movement. Ratified on August 18, 1920, this amendment states: "The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of sex." This was the culmination of a long struggle by women and their allies, who campaigned for nearly a century to secure voting rights.

The other amendments listed do not pertain to women's voting rights. The 18th Amendment established Prohibition, the 21st Amendment repealed Prohibition, and the 24th Amendment eliminated poll taxes in federal elections. Each of these amendments addresses separate but significant issues in American history, none of which are related to women's suffrage. The 19th Amendment stands as a crucial victory in the fight for gender equality in the electoral process.
