The Nineteenth Amendment was finally ratified in August 1920, due not only to the result of the tireless effort of women's suffrage organizations, but also to the close collaboration of various women's groups all across the United States during the Progressive Era. Many women's organizations, arising from church activities in the 1 9th century, had widen their sphere of influence, entered into a league making clear their political stances. Though it has been asumed that middle-class activists approached women unionists and elite professionals to cooperate together at the final phase, the key to the movement's success was in reality the coming of age of each women's organization to attain its own politics. To clarify this, I would like to present a historical overview on the development of women's organizations in the Progressive Era, especially focusing on Oak Park Women's Club in Illinois, the increase in women laborers, and New York 20,000 strikers in 1909 to illustrate their aims that ultimately resulted in their collaboration to effect the women's suffrage movement.
