"Brave women like Elizabeth Cady Stanton and Susan B. Anthony had been the early pioneers, facing abuse and ridicule, violence and even arrests for attempting to vote. Later, women like Dr. Anna Howard Shaw and Carrie Chapman Catt headed the National American Women's Suffrage Association, which struggled against "the lethargy of women and the opposition of men." But by 1916 a younger, bolder and more militant group emerged, which was dissatisfied with the slower process of winning suffrage, state by state, and fought for a constitutional amendment."
