The 19th Amendment to the United States Constitution was proposed by Congress on June 4, 1919, and added to the Constitution on August 18, 1920. It was originally introduced by Senator Aaron A. Sargent in 1878; it was not submitted to the states for ratification until 41 years later.

Until the 1910s, most states had not granted women the right to vote. This 19th Amendment was the endpoint of the women's suffrage movement in the United States, which had struggled to enforce the right to vote both at state and national levels. This superseded a Supreme Court ruling of 1875 (Minor v. Happersett) in which it was unanimously decided that the 14th Amendment did not give women the right to vote.  

Decisive for the admission was the approval of the state of Tennessee, which ratified him as the 36th state. Secretary of State Bainbridge Colby certified the ratification on August 26, 1920. The Amendment prohibits the federal government and states from prohibiting access to an election based on gender.
