What were the causes and consequences of the Red Scare in the 1920s?

The Red Scare of the 1920s was primarily caused by the fear of communism and anarchism following the Russian Revolution of 1917 and a series of labor strikes in the U.S., which were perceived as potential revolutionary movements. This paranoia led to widespread government crackdowns, including the Palmer Raids, which targeted suspected radicals and immigrants. The consequences included heightened anti-immigrant sentiment, the suppression of civil liberties, and the establishment of a culture of fear that stifled dissent and political activism. Ultimately, the Red Scare contributed to the polarization of American society and set a precedent for future anti-communist sentiments.
