Women's poll tax repeal movement
The women's poll tax repeal movement was a movement in the United States, predominantly led by women, that attempted to secure the abolition of poll taxes as a prerequisite for voting in the Southern states. The movement began shortly after the ratification in 1920 of the Nineteenth Amendment to the United States Constitution, which granted suffrage to women.
