In 1899 and 1907, world leaders sought peace by convening an innovative and influential peace conference at The Hague. These conferences produced Hague Conventions of 1899 and 1907. A 1914 conference was canceled due to World War I. The void was filled by an unofficial conference convened by Women at the Hague. At the time, both the US and The Netherlands were neutral. Jane Addams chaired this pathbreaking International Congress of Women at the Hague, which included almost twelve hundred participants from 12 warring and neutral countries. Their goal was to develop a framework to end the violence of war. Both national and international political systems excluded women's voices. The women delegates argued that the exclusion of women from policy discourse and decisions around war and peace resulted in flawed policy. The delegates adopted a series of resolutions addressing these problems and called for extending the franchise and women's meaningful inclusion in formal international peace processes at war's end. Following the conference, Addams and a congressional delegation traveled throughout Europe meeting with leaders, citizen groups, and wounded soldiers from both sides. Her leadership during the conference and her travels to the Capitals of the war-torn regions were cited in nominations for the Nobel Peace Prize.
