What happened
The campaign for women's suffrage had run for more than seventy years, from the 1848 Seneca Falls convention through decades of state-by-state fights, marches, and civil disobedience. Congress passed the Nineteenth Amendment on June 4, 1919, and sent it to the states. Ratification came down to Tennessee, which on August 18, 1920, became the 36th state to ratify, meeting the three-quarters threshold. The amendment declared that the right to vote shall not be denied or abridged on account of sex, and it was certified into law on August 26, 1920. The victory was real but incomplete: many Black women, especially in the Jim Crow South, and Native American women, who were not even recognized as citizens until 1924, remained shut out of the polls.
Why it matters
The Nineteenth Amendment enfranchised roughly half the adult population and stands as one of the largest single expansions of democracy in American history. It also showed both the power and the limits of constitutional change: winning the legal right to vote did not, on its own, deliver it to women of color, whose full access would depend on the later voting rights struggle.
How we know
The amendment and its ratification are recorded in the National Archives, and the June 1919 congressional passage and August 1920 Tennessee ratification are documented in the legislative and state records.
