The Red Scare refers to the intense fear of communism and radical leftist ideologies that swept through the United States in the early 20th century, particularly after World War I and during the late 1940s and early 1950s. This period was marked by widespread paranoia, government crackdowns on perceived dissent, and the persecution of individuals believed to be associated with communist movements. The Red Scare significantly influenced American politics, culture, and society, creating an atmosphere of fear and suspicion.
