During the late 1800s and early 1900s peace movements began to appear across Europe and North America. The significant voices were those of the women such as Jane Addams and Berta Von Suttner. They were influential to the processes of peace-making and their peace-building activities were aligned with anti-war strategies that aimed to establish peace-through-justice and peace-through-politics. Several organisations devoted to peace were formed in the United States as a result of the work of the American, Jane Addams, and internationally the Women’s International League for Peace and Freedom. Feminist movements, focussing upon care, compassion and collaboration, have positively changed the way peace is defined and created. They challenged the prevailing political beliefs by seeking nonviolent resolution to conflict.
