Ratification of the 19th Amendment: Timeline Map
"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." The United States Congress passed the 19th Amendment, or "Susan B. Anthony Amendment" on June 4, 1919 and sent it to the states for ratification. At the time, women needed 36 states to ratify the 19th Amendment for it to be signed into law. Between June 1919 and August 1920 states argued, ratified, and rejected the 19th Amendment which was ultimately made official on August 26, 1920. The last ratification did not occur until 1984.
