American Peace Crusade

American Peace Crusade (APC) was an American peace advocacy organization. Established during the Korean War, the federal government identified the organization as a Communist front.Pitirim Sorokin, a Russian American sociologist and professor at Harvard University, was a sponsor of this organization. The Guide to Subversive Organizations and Publications published by the House Un-American Activities Committee (HUAC) characterized APC as a group formed by the Communists to function "as a new instrument for their 'peace' offensive in the United States."

American Peace Crusade is characterized as "Communist-led peace group", and a "pro-Soviet peace initiative". Historian Marian Mollin notes that the APC believed the United States to be the "greatest threat to world peace". According to historian Lawrence S. Wittner, the APC was the last Communist-headed peace organization in the United States.

The APC was established in 1951 following the dissolution of the Peace Information Center. The founding committee included W.E.B. Du Bois, chemist Linus Pauling, and physicist Philip Morrison. Especially because of the provocative comments made by General of the Army Douglas MacArthur, American Peace Crusade feared that the Korean War would culminate in nuclear holocaust. The organization supported the withdrawal of US troops from the Korean Peninsula, talks with the People's Republic of China (PRC), and the removal of Douglas MacArthur, which the group believed would help ending the war.
