On September 6, 1870, in Laramie, Wyoming, Louisa Ann Swain became the first woman in the United States to cast a legal ballot since 1807. Wyoming had passed laws granting women the right to vote the previous year, making it the first territory to do so. Swain, a seventy-year-old grandmother, was chosen by local officials to make the historic ballot.
Her action drew national attention and symbolized the opening of democratic rights to women. At a time when most states denied women the vote, Wyoming stood out as a pioneer, later gaining statehood in 1890 with full suffrage rights intact. Swain’s vote became a rallying point for suffragists across the country who were pressing for legal equality.
The act also helped show that women could responsibly take part in civic life. Today, her memory is honored annually in Wyoming on Louisa Swain Day, reminding people of her quiet but historic role. Her action marked the first small step toward the eventual passage of the 19th Amendment in 1920, which finally granted voting rights to women across the nation.
