The Wyoming legislators write the first state constitution granting women the right to vote. It was signed into law on December 10, 1869, by Territorial Governor John Allen Campbell. On September 6, 1870, Louisa Ann Swain of Laramie, Wyoming became the first woman to cast a vote in a general election.
In 1890, when the U.S. Congress demanded Wyoming rescind the right of women to vote as a condition of becoming a State. Wyoming, with a Republican governor and Democratic legislature, insisted it would not become a state without keeping women's suffrage. Congress gave in, and Wyoming became the 44th State and the first U.S. State in which women could vote on July 10, 1890.
