What was the term for the attacks by Senator Joseph McCarthy on individuals suspected of being Communists in the early 1950s?

The term that specifically refers to the attacks by Senator Joseph McCarthy on individuals suspected of being Communists in the early 1950s is McCarthyism. This term encapsulates not only the actions and rhetoric employed by McCarthy but also the broader atmosphere of fear and suspicion during that time. McCarthyism is characterized by aggressive investigations and accusations without proper evidence, leading to the tarnishing of reputations and careers of many individuals in government, entertainment, and other sectors.

While the Red Scare refers to the general public fear of communist influence and the threat posed by communism, it is not exclusive to McCarthy's actions. Blacklisting pertains to the practice of barring individuals from employment due to their alleged communist ties, often in the entertainment industry. The House Un-American Activities Committee (HUAC) played a significant role in investigating communist influences, but McCarthyism is specifically tied to the actions and methods of Senator McCarthy himself. Thus, McCarthyism captures the essence of the period defined by his tactics and the resultant paranoia.
