 Walter Laqueur traces the Jewish-Bolshevik conspiracy theory to Nazi ideologue Alfred Rosenberg, for whom Bolshevism was "the revolt of the Jewish, Slavic and Mongolian races against the German (Aryan) element in Russia".Germans, according to Rosenberg, had been responsible for Russia's historic achievements and had been sidelined by the Bolsheviks, who did not represent the interests of the Russian people, but instead those of its ethnic Jewish and Chinese population.Michael Kellogg, in his Ph.D. thesis, argues that the racist ideology of Nazis was to a significant extent influenced by White émigrés in Germany, many of whom, while being former subjects of the Russian Empire, were of non-Russian descent
