Women's suffrage was established in the United States on a full or partial basis by various towns, counties, states, and territories during the latter decades of the 19th century and early part of the 20th century. As women received the right to vote in some places, they began running for public office and gaining positions as school board members, county clerks, state legislators, judges, and, in the case of Jeannette Rankin, as a member of Congress.

The campaign to establish women's right to vote in the states was conducted simultaneously with the campaign for an amendment to the United States Constitution that would establish that right fully in all states. The campaign succeeded with the ratification of Nineteenth Amendment in 1920.
