For more than a century women and women's organizations and movements have mobilized in support of peace and disarmament. In addition to participating in organizations alongside men, many women have found it more effective to organize separately.
There are numerous examples of national, regionaland international women's organizations and movements with a primary focus on peace or disarmament. For example, during World War I, nearly 1,200 women from warring and neutral countries came together to protest the conflict. They eventually formed the Women's International League for Peace and Freedom (WILPF).
