Suspected Communists refers to individuals who were believed to have ties to or sympathies for communist ideologies during the Red Scare periods in American history, particularly the one following World War I and the later one in the late 1940s through the 1950s. This label often led to widespread paranoia and a culture of fear, resulting in investigations, accusations, and even violations of civil liberties as people were targeted based on mere suspicion or political beliefs rather than concrete evidence.
