National syndicalism is a far-right adaptation of syndicalism to suit the broader agenda of integral nationalism. National syndicalism developed in France in the early 20th century, and then spread to Italy, Spain, and Portugal. French national syndicalism was an adaptation of Georges Sorel's version of revolutionary syndicalism to the monarchist ideology of integral nationalism, as practised by Action Française. Action Française was a French nationalist-monarchist movement led by Charles Maurras. In 1900, Charles Maurras declared in Action Française'''s newspaper that anti-democratic socialism is the "pure" and correct form of socialism. From then on, he and other members of Action Française (like Jacques Bainville, Jean Rivain, and Georges Valois) interested in Sorel's thought discussed the similarity between the movements in Action Française's conferences and in essays published in the movement's newspaper, hoping to form a collaboration with revolutionary syndicalists. Such collaboration was formed in 1908 with a group of labor unions' leaders led by Émile Janvion. As a result of this collaboration, Janvion founded the anti-republican journal Terre libre. Georges Sorel is sometimes described as the father of revolutionary syndicalism. He supported militant trade unionism to combat the corrupting influences of parliamentary parties and politics, even if the legislators were distinctly socialist. As a French Marxist who supported Lenin, Bolshevism and Mussolini concurrently in the early 1920s, Sorel promoted the cause of the proletariat in class struggle, and the "catastrophic polarization" that would arise through social myth-making of general strikes. The intention of syndicalism was to organize strikes to abolish capitalism; not to supplant it with State socialism, but rather to build a society of worker-class producers. This Sorel regarded as "truly true" Marxism. In 1909, the integral nationalists Action Française began to work with Sorel. The connection was formed after Sorel read the second edition of Maurras' book, Enquête sur la monarchie.
