By December 1914, Wales had become horrified and physically sickened by the
First World War reports coming from Europe. A close friend of hers wrote that "the pity and horror of it seized upon her". Convinced that the war was both irrational and un-Christian, Wales published her views and a solution for the end of the war in a pamphlet entitled "Continuous Mediation Without Armistice", popularly known as the
Wisconsin Plan. Her plan was to have the United States organize a conference of intellectual mediators from neutral nations, who would receive suggestions from the belligerent nations while at the same time discussing possible solutions to the war. The plan was endorsed by several
anti-war and
peace movements, as well as by the
Wisconsin Legislature. As a delegate, Wales represented the Wisconsin Peace Society at the
International Congress of Women, held at
The Hague in April 1915. She thus became a founding member of the
Women's International League for Peace and Freedom. As a member of the conference's embassy, Wales took her proposal, adopted as a resolution of the conference, to European governments. Her plan failed when the
United States entered the war in April 1917, and she returned to North America to resume her academic career. == Later life ==
