What is the 19th Amendment?

The 19th Amendment reads: 'Section 1. 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. Section 2. The Congress shall have power to enforce this article by appropriate legislation.' The amendment is an absolute prohibition on sex-based denial or abridgment of the right to vote. It applies to all elections -- federal, state, and local. Congress passed the 19th Amendment on June 4, 1919, and sent it to the states for ratification. Tennessee provided the decisive 36th ratification on August 18, 1920, completing the three-fourths majority of the then-48 states required by Article V of the Constitution. The 19th Amendment took effect immediately.

The push for the 19th Amendment grew from a suffrage movement that spanned more than seven decades. The organized campaign began formally with the Seneca Falls Convention of July 19-20, 1848, in Seneca Falls, New York -- the first women's rights convention in American history. Delegates adopted the Declaration of Sentiments, modeled on the Declaration of Independence, which demanded the right to vote among other civil and social reforms. Susan B. Anthony and Elizabeth Cady Stanton became the central leaders of the national suffrage movement in the decades that followed. Anthony was arrested and tried in 1872 for voting in a federal election in Rochester, New York, under the theory that the 14th Amendment's citizenship clause already extended the franchise to women. The Supreme Court rejected that theory in Minor v. Happersett, 88 U.S. 162 (1875), ruling unanimously that the 14th Amendment did not grant women the right to vote and that suffrage was not among the privileges or immunities of national citizenship. The Minor decision made clear that a constitutional amendment was the only reliable path. Wyoming led the way at the territorial level, granting women the right to vote in 1869; it retained that guarantee upon statehood in 1890.

Ratification of the 19th Amendment was decided by a single vote in the Tennessee House of Representatives. The amendment had cleared the Tennessee Senate, but the House was evenly divided. Harry T. Burn, a 24-year-old Republican state representative, had been expected to vote against ratification. He changed his vote to yes after receiving a letter from his mother, Phoebe Burn, urging him to 'be a good boy' and vote for suffrage. His vote made Tennessee the 36th state to ratify and completed the three-fourths threshold. The amendment was certified by the U.S. Secretary of State on August 26, 1920, which is now observed as Women's Equality Day.

For the 2028 presidential election, the 19th Amendment means that no state or federal authority may deny or abridge the right to vote on account of sex. Any U.S. citizen who meets their state's age and registration requirements -- who is at least 18 years old as provided by the 26th Amendment, registered in their state of residence, and not otherwise disenfranchised -- is entitled to vote in the 2028 presidential election regardless of sex. State voter ID laws, registration deadlines, and absentee-ballot requirements apply equally to all voters and are governed by separate legal frameworks. The 19th Amendment's protection is unconditional: no financial barrier (24th Amendment), no age barrier above 18 (26th Amendment), and no sex-based barrier (19th Amendment) may prevent an eligible citizen from voting in 2028.
