What two factors characterlized the Red Scare?

The Red Scare was characterized primarily by widespread fear of communism and radical leftist ideologies, particularly following the Russian Revolution of 1917. This period saw heightened paranoia about potential communist infiltration in American society, leading to government crackdowns on suspected radicals, labor movements, and immigrants. Additionally, the Red Scare was marked by significant violations of civil liberties, including arrests, deportations, and the establishment of the Palmer Raids.
