The American Student Union (ASU) was a national organization of college students of the 1930s and is best remembered for its protest activities against militarism. Founded in 1935 by a merger of Communist and Socialist student organizations, the ASU was affiliated with the American Youth Congress. The group was investigated by the Dies Committee (https://www.britannica.com/topic/House-Un-American-Activities-Committee)of the United States House of Representatives in 1939 over its connections to the Communist Party USA. With the group's Communist-dominated leadership consistently supportive of the twists and turns of Soviet foreign policy, the Socialist minority split from the group in 1939. The organization was terminated in 1941.
