"Syndicalism" is used by some interchangeably with "anarcho-syndicalism". A central debate concerned the relation between anarchism and syndicalism (or trade unionism). French syndicalism and American industrial unionism influenced the rise of syndicalism elsewhere. Furthermore, Italian Fascism also acknowledged socialist influences, such as revolutionary syndicalism. The fusion of Maurrassian nationalism and Sorelian syndicalism influenced radical Italian nationalist Enrico Corradini. Italian Fascism had ideological connections with revolutionary syndicalism, in particular Sorelian syndicalism. Others believe both are possible (e.g. syndicalism or various forms of Marxism). To radical workers, the programmatic distinctions between syndicalism and communism were not all that relevant. Sorel was not the first to drift towards nationalism and syndicalism. A number of Italian fascist leaders began to relabel national syndicalism as Fascist syndicalism. Scholars have given several explanations for the emergence of syndicalism. The term "syndicalism" has French origins. International work processes also contributed to the diffusion of syndicalism. Similarly, southern workers were more drawn to syndicalism in Italy. Additionally, according to Altena syndicalism lost out to sports and entertainment in the cultural sphere.
