What was the purpose of the Red Scare?

The Red Scare, particularly the first one following World War I and the second during the Cold War, aimed to address the fear of communism and radical leftist ideologies infiltrating American society. It involved widespread paranoia about potential communist subversion, leading to government crackdowns on perceived radicals, including labor organizers and leftist activists. The purpose was to maintain national security and social order by promoting anti-communist sentiments and policies, often resulting in violations of civil liberties. Ultimately, it reflected broader anxieties about social change and political stability in the United States.
