Some of the many groups that protested against the war, as well as the traditional peace churches, were the Woman's Peace Party (which was organized in 1915 and led by noted reformer Jane Addams), the International Committee of Women for Permanent Peace (ICWPP) (also organized in 1915),[20] the American Union Against Militarism, the Fellowship of Reconciliation, and the American Friends Service Committee.[21] Jeannette Rankin, the first woman elected to Congress, was another fierce advocate of pacifism, the only person to vote no to America's entrance into both World Wars.
