McCarthyism, an anti-communist movement led by Senator Joseph McCarthy, surged in the 1950s Cold War era, fueled by fears of Soviet espionage and the spread of communism. It profoundly affected American culture and politics, leading to widespread fear, suspicion, and the undermining of civil liberties. The movement's decline began with the Army-McCarthy hearings and Senator McCarthy's eventual censure.
