CIO also stands for the '''[[Congress of Industrial Organizations]]''' a coalition of industrial unions that split away from the [[American Federation of Labor|AFL]] in the late 1930s under [[John L. Lewis]]. The CIO and AFL fought bitterly in the late 1930s; both grew very rapidly during [[World War II]], and both supported the [[New Deal Coalition]] of [[Franklin D. Roosevelt]] and [[Harry S. Truman]]. Many Communists held positions of power in the CIO until they were purged in 1947-48. [[Walter Reuther]] of the autoworkers [[UAW]] was the most influential leader. Reuther helped purge the Communists and promoted an anti-Communist foreign policy as well as liberalism on economic issues. The CIO reunited with the AFL in 1955 to form the AFL-CIO, which remains the largest coalition of labor unions. | CIO also stands for the '''[[Congress of Industrial Organizations]]''' a coalition of industrial unions that split away from the [[American Federation of Labor|AFL]] in the late 1930s under [[John L.
