On September 30, 1889, the Wyoming state convention approves a constitution that includes a provision granting women the right to vote. Formally admitted into the union the following year, Wyoming thus became the first state in the history of the nation to allow its female citizens to vote.
That the isolated western state of Wyoming should be the first to accept women’s suffrage was a surprise. Leading suffragists like Susan B. Anthony and Elizabeth Cady Stanton were Easterners, and they assumed that their own more progressive home states would be among the first to respond to the campaign for women’s suffrage. Yet the people and politicians of the growing number of new Western states proved far more supportive than those in the East.
