When Rankin was elected, most women didn’t even have the right to vote. The U.S. government didn’t grant women across the country this right until 1920. But Rankin’s state, Montana, was one of a few states that let women vote sooner. Rankin and others convinced state officials to let women vote starting in 1914. Two years later, Rankin ran for Congress. Both men and women in Montana voted for her, and she won.
Congress is made up of two parts. They are the House of Representatives and the Senate. Rankin represented her state in the House of Representatives. She served from 1917 to 1919. She was elected to a second term in 1940.
