Italian Fascism had ideological connections with revolutionary syndicalism, in particular Sorelian syndicalism. Benito Mussolini mentioned revolutionary syndicalist Georges Sorel—along with Hubert Lagardelle and his journal "Le Mouvement socialiste", which advocated a technocratic vision of society—as major influences on fascism. According to Zeev Sternhell, World War I caused Italian revolutionary syndicalism to develop into a national syndicalism reuniting all social classes, which later transitioned into Italian Fascism, such that "most syndicalist leaders were among the founders of the Fascist movement" and "many even held key posts" in the Italian Fascist regime by the mid-1920s.
