Red Scare

Red Scare was the term given to the fear of the potential rise of communism and radical leftism in the United States. The First Red Scare referred to the fear of socialist revolution and political radicalism, while the Second Red Scare referred to communism influencing society and infiltrating the federal government.

The Red Scare was the cause of the Palmer Raids during November 1919 and January 1920, under the supervision of Attorney General Alexander Mitchell Palmer.
