What did the Russian Revolution have to do with the Palmer Raids?

The Russian Revolution of 1917 heightened fears of communism and radicalism in the United States, leading to widespread anxiety about potential uprisings. In response, the U.S. government, under Attorney General A. Mitchell Palmer, initiated the Palmer Raids in 1919-1920 to arrest and deport suspected radicals, particularly anarchists and communists. These raids were part of a broader Red Scare that sought to suppress leftist movements and curb Immigration, reflecting the pervasive fear of Bolshevism following the revolution. Thus, the Russian Revolution significantly influenced the intense anti-communist sentiment that fueled the Palmer Raids.
