House Un-American Activities Committee

The House Un-American Activities Committee was established in 1938 under Chairman Martin Dies Jr. to investigate subversive activities and extremist movements in American society. Originally focused on Nazi and fascist activities, HUAC shifted its attention to communist threats following World War II, becoming the primary congressional body for investigating alleged communist sympathizers during the McCarthy era.

HUAC's most notorious period occurred from 1947-1954, when it investigated Hollywood figures, government employees, labor union leaders, and intellectuals suspected of communist ties. The committee's Hollywood hearings in 1947 led to the blacklisting of the "Hollywood Ten" and hundreds of other entertainment industry professionals who refused to cooperate or were deemed security risks. HUAC pioneered the use of public hearings as political theater, often destroying careers through guilt by association and innuendo.

Notable investigations included the Alger Hiss case, which launched Richard Nixon's political career, and confrontations with prominent figures like playwright Arthur Miller and folk singer Pete Seeger. HUAC's methods included demanding names of communist associates, threatening contempt citations for non-cooperation, and publicizing unsubstantiated allegations that effectively ended careers and reputations.

The committee's influence waned after the Army-McCarthy hearings of 1954 exposed the excesses of anti-communist investigations. HUAC was renamed the House Internal Security Committee in 1969 and abolished in 1975, with its functions transferred to the House Judiciary Committee. The committee remains controversial for its violations of civil liberties and constitutional rights during the Cold War period.
