What are some cause and effect events from the Red Scare in the 1920s?

The Red Scare of the 1920s was primarily caused by the fear of communism following the Russian Revolution and the rise of labor strikes in the U.S. This paranoia led to the Palmer Raids, where government agents arrested thousands of suspected radicals without proper legal procedures. The crackdown on dissent resulted in heightened anti-immigrant sentiment and the erosion of civil liberties, as many individuals faced deportation or imprisonment based on flimsy evidence. Ultimately, the Red Scare fostered a culture of fear that stifled political discourse and dissent in American society.
