In the United States, women universally gained the right to vote, called women's suffrage, on Aug. 26, 1920, through the 19th Amendment to the U.S. Constitution. Eight million women exercised their right to vote during the November election that same year.
In 1848, Elizabeth Cady Stanton and Lucretia Mott organized a convention in Seneca Falls, N.Y. There, the delegates drafted the Declaration of Sentiments, proclaiming the need for equal rights among the sexes, especially the right to vote. Over the 70 years between the convention and the 19th Amendment, women slowly but steadily gained equality and independence as Wyoming, Colorado, Idaho and Utah extended suffrage to women, all before the 20th century. The Southern states strongly opposed the ratification of the 19th Amendment, but Tennessee finally voted to ratify on August 24 as the 36th and final state necessary for Constitutional inclusion.
