Economic conditions, however, were impelling the workingmen to union. Since the Commune, the industrial development of France had gone on without interruption, concentrating the economic powers of the employing classes. In the face of the economic organizations of the employers, the scattered and isolated syndicats were of little significance, and the necessity of a larger combination made itself felt. Besides, in 1884, a new law on syndicats was passed. This law authorized the formation of syndicats under certain conditions of which article 4 was obnoxious to the workingmen. This article 4 of the new law made it obligatory for every syndicat to send in the names and addresses of its administrators to the municipal authorities. In Paris they had to be sent to the Prefect of the Police. The workingmen thought that this condition would subject them to the mercy of the police and of the employers, and they wanted to manifest their attitude to the new law. Under these conditions a general congress of syndicats was called in Lyons in October, 1886. Organized workingmen of various political opinions met here and at once the sentiments and needs which brought them together found expression in the report of the Committee on Organization from which the following lines may be quoted: We are organized workingmen who have made a study of social problems and who have recognized that the diversity of doctrines contributes powerfully to divide us instead of uniting us. Slaves of the same master, bearing the same claims, suffering from the same evils, having the same aspirations, the same needs and the same rights, we have decided to set aside our political and other preferences, to march hand in hand, and to combine our forces against the common enemy. The problems of labor have always the power of uniting the workingmen.[68] [68] _Séances du Congrès Ouvrier_, session de 1886, pp. 18-19. The first question on the program of the Congress was the "prospect of a Federation of all workingmen's syndicats." The discussion brought out the fact that the delegates had different ideas on the future rôle of the Federation. Still the majority united on the following resolution: Considering that in face of the powerful bourgeois organization made without and against the working-class, it not only behooves, but it is the duty of the latter to create, by all means possible, groupings and organizations of workingmen against those of the bourgeois, for defense first, and we hope for offensive action soon afterwards;
