Georges Sorel
According to historian Zeev Sternhell, "most syndicalist leaders were among the founders of the Fascist movement", who in later years gained key posts in Mussolini's regime. Mussolini expressed great admiration for the ideas of Georges Sorel, who he claimed was instrumental in birthing the core principles of Italian fascism. J. L. Talmon argued that Fascism billed itself "not only as an alternative, but also as the heir to socialism".
