The House Un-American Activities Committee (HUAC) was a congressional committee established in 1938 to investigate alleged disloyalty and subversive activities by private citizens, public employees, and organizations suspected of having communist ties. It gained notoriety during the Cold War for its aggressive investigations into Hollywood figures, labor unions, and other groups, reflecting the heightened fears of communism and the Red Scare. Its activities played a significant role in the cultural and political climate of the era.
