Jewish Bolshevism
Jewish Bolshevism, also Judeo–Bolshevism, is an antisemitic, anti-communist conspiracy theory, and myth that claims that a Jewish conspiracy was behind the Russian Revolution of 1917, controlled the Soviet Union and international communist movements, and had a secret plan to control or destroy Western civilization; or, more generally, it is the antisemitic myth that Bolshevism was fundamentally Jewish. It was one of the main Nazi beliefs that served as an ideological justification for the German invasion of the Soviet Union and the Holocaust.
