In France the most interesting development has taken place. From the Revolution until 1864 no labor organizations were allowed. The National Assembly abolished all the trade guilds and corporations. The _Loi le Chappelier_ forbade unions of workers and of masters, and the _Code Napoléon_ imposed a penalty of imprisonment on those engaging in unlawful combinations. In 1864 the criminal laws were revised, and unions of twenty members were allowed. The law of 1884 left the way untrammeled for their development.[22] Within a few years unions were formed everywhere.[23] In 1886 the Guesdists organized the National Federation of Trade Unions, a Socialist body of workers subordinated to the Workingman's Party. Soon thereafter the Municipal Socialists, the Broussists, founded the Paris Labor Exchange, built a large clubhouse for if, and succeeded in getting an appropriation of 20,000 francs a year from the city for its maintenance. Within ten years about fifty of these exchanges were formed in as many cities, and about seventy per cent. of the union members belonged to them. The object of these exchanges was educational and benevolent. But they were soon made the hotbeds of Socialistic politics. In 1892 they were all federated in the Federation of Labor Exchanges (Fédération du Bourse du Travail). In 1895 Guesde's political adjunct, the National Federation of Trade Unions, became extinct. The Blanquists then organized a new federation, the notorious General Confederation of Labor (Confédération Générale du Travail), commonly called the C.G.T. These two bodies were bitter rivals, after the French fashion, until, in 1902, they amalgamated, retaining the name C.G.T.[24] The organization is dual, retaining the benevolent activities of the local exchanges and the trade activities of the local unions. These activities are federated into national councils. The union of these councils forms the central governing body of C.G.T. The organization allows a great deal of local autonomy, but the central control is none the less effective. In 1907 the C.G.T. claimed 350,000 members, in 1911 it reported 600,000. This body of workmen is known for its violence. Within its ranks has spread the doctrine known as revolutionary Syndicalism, a resurrection of the spirit of Proudhonism in the body of labor unionism. Briefly stated, it is class war in its most violent form without the aid of parliaments and politics; with the enginery of the general strike, and the spirit of universal upheaval and anarchy. It is the most effective outbreak of Anarchism since the days of Bakunin. The intellectual revival of the doctrine of violence may be dated from the appearance of Georges Sorel's book, _The Socialist Future of Trade Unions_, in 1897, and the culmination of the tide in his volume _Reflections upon Violence_, in 1908.
