At the same time, Mussolini and many of his revolutionary syndicalist adherents gravitated towards a form of revolutionary nationalism in an effort to "identify the 'communality' of man not with class, but with the nation". According to A. James Gregor, Mussolini came to believe that "Fascism was the only form of 'socialism' appropriate to the proletarian nations of the twentieth century" while he was in the process of shifting his views from socialism to nationalism. Enrico Corradini, one of the early influences on Mussolini's thought and later a member of his administration, championed the concept of proletarian nationalism, writing about Italy in 1910: "We are the proletarian people in respect to the rest of the world. Nationalism is our socialism". Mussolini would come to use similar wording, for instance referring to Fascist Italy during World War II as the "proletarian nations that rise up against the plutocrats".
