Who did the house on in-American activities activities committee investigate And what happened to those who were found to be communist?

The House Un-American Activities Committee (HUAC) primarily investigated individuals in the entertainment industry, government, and academia, targeting suspected communists and communist sympathizers during the Red Scare, particularly in the late 1940s and 1950s. Those found to be affiliated with the Communist Party often faced blacklisting, which barred them from employment in their fields, as well as social ostracism and legal repercussions. Some individuals, like the Hollywood Ten, were also jailed for contempt of Congress for refusing to testify. The committee's activities contributed to a climate of fear and repression during the Cold War era.
