- Carrie Chapman Catt played a significant role in women winning the right to vote in the United States.
Carrie Chapman Catt became a strong leader of the National American Woman Suffrage Association (NAWSA) in 1915. Under her leadership, the group gained support from state and national leaders, which ultimately led to the passing of the Nineteenth Amendment to the Constitution in 1920, granting women the right to vote. Catt's skills as a leader and her ability to rally support were crucial in achieving this milestone for women's rights.
