The amendment that gave women the right to vote in the United States is the 19th Amendment to the U.S. Constitution. It was passed by Congress on June 4, 1919, and ratified on August 18, 1920. The amendment prohibits the United States or any state from denying the right to vote on the basis of sex, thereby granting women the legal right to vote.
The official text of the 19th Amendment reads: "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. Congress shall have power to enforce this article by appropriate legislation".
This amendment was the culmination of a long struggle by women's suffrage supporters that began in the mid-19th century and involved decades of activism, lobbying, and protest.
