During the McCarthy Era of the 1950s in America, Senator Joseph McCarthy exploited fears about communism for political gain. He claimed to have a list of government employees who were communists and launched accusations with little evidence. McCarthyism led to widespread paranoia where Americans were denounced as communist sympathizers. It influenced society through restrictions on education, censorship of media, and promotion of pro-American ideals. McCarthy's accusations eventually lost credibility and he was censured after televised hearings showed his bullying behavior, marking the end of the McCarthy Era.
