Mary McLeod Bethune was involved in the planning for postwar peace. On April 25th 1945, Bethune alongside W.E.B. Dubois and Walter White were sent to San Francisco by President Harry S. Truman to the organizing meeting of the United Nations as consultants. Afterwards, she released a statement that San Francisco was building a bridge towards brotherhood, security, opportunity and peace. She was also invited by president Dumarsais of Haiti in the celebration of the 1949 Haitian Exposition and was given the medal of honor and merit, becoming the first woman to earn the award. She also attended the World Assembly for Moral Re-Armament in Caux, Switzerland. This organization subscribed to Bethune’s principles of absolute honesty, unselfishness and love.
