The Nineteenth Amendment to the United States Constitution prohibits any United States citizen from being denied the right to vote on the basis of sex. It was ratified on August 18, 1920. The Constitution allows the states to determine the qualifications for voting, and until the 1910s most states disenfranchised women. The amendment was the culmination of the women's suffrage movement in the United States, which fought at both state and national levels to achieve the vote. It effectively overruled Minor v. Happersett, in which a unanimous Supreme Court ruled that the Fourteenth Amendment did not give women the right to vote. Colloquially known as the "Anthony Amendment", the 19th Amendment was first introduced in Congress in 1878 by Senator Aaron A. Sargent. 41 years later, in 1919, Congress approved the amendment and submitted it to the states for ratification. .
