Why was Alice Paul such a significant woman during the Progressive Era?

She was the president of the National Woman's Suffrage Association and an author.

She was the leader of the suffrage movement's most militant wing and proposed an Equal Rights Amendment in 1920.

She was an African American author who wrote books about racism and separation of races.

She was the first woman to graduate from Harvard Law School.

Alice Stokes Paul was an American feminist activist, who led the campaign for the Nineteenth Amendment to the United States Constitution. Trained in British activism with Emmeline Pankhurst as a point of reference, Paul envisioned the struggle for suffrage with radical measures and forms, far from the moderation of the National Association of the Suffrage of American Women. In addition, its sole objective was to reform the country's Constitution, instead of carrying out state-by-state referendums. She was expelled from the association in 1916 and founded the National Women's Party, with which she continued her activism for more than half a century.
