Which group was the target of the 1920's red scare?

The 1920s Red Scare primarily targeted leftist groups, particularly communists and anarchists, as well as labor unions and immigrant communities associated with radical political ideologies. Following the Russian Revolution of 1917, there was widespread fear in the United States that a similar communist uprising could occur. This led to heightened paranoia and the implementation of measures like the Palmer Raids, where government agents arrested and deported suspected radicals without proper legal procedures. The fear of subversion and revolution significantly influenced American politics and society during this period.
