In her address to the National American Woman Suffrage Association's (NAWSA) 50th convention in St. Louis, Missouri, President Carrie Chapman Catt proposed the creation of a "league of women voters to finish the fight and aid in the reconstruction of the nation." Women Voters was formed within the NAWSA, composed of the organizations in the states where suffrage had already been attained. The next year, on February 14, 1920 - six months before the 19th amendment to the Constitution was ratified - the League was formally organized in Chicago as the national League of Women Voters. Catt described the purpose of the new organization:
"The League of Women Voters is not to dissolve any present organization but to unite all existing organizations of women who believe in its principles. It is not to lure women from partisanship but to combine them in an effort for legislation which will protect coming movements, which we cannot even foretell, from suffering the untoward conditions which have hindered for so long the coming of equal suffrage. Are the women of the United States big enough to see their opportunity?"
