Meantime the anarchists had been busy in this country. In 1881, the year which marks the birth of the American Federation of Labor (then called the Federation of Organized Trades and Labor Unions of the United States and Canada), the difference between them and those who advocated political action finally assumed definite form in the organization by the anarchist advocates of physical force of the Revolutionary Socialist party. In 1883 there was held a joint convention of the "revolutionary socialists" and the anarchists which resulted in the birth of the International Working People's Association.[23] At this convention were gathered representatives of anarchist and revolutionary socialist groups from twenty-six cities. These delegates drafted the famous Pittsburgh proclamation which demanded "the destruction of the existing government by all means, _i. e._, by energetic, implacable, revolutionary and international action" and the establishment of an industrial system based upon "the free exchange of equivalent products between the producing organizations themselves and without the intervention of middlemen and profit-making."[24] In the course of two years the membership of the International grew to about 7,000. Then in 1888 came the Haymarket tragedy and the International soon passed out of existence. The anarchists were in control of this organization and great stress was laid upon revolutionary tactics and direct action, with a corresponding depreciation of political action. John Most, the anarchist, had come to this country in 1882 and the organization of the International Working People's Association was largely due to his agitation here. There is no doubt that all the main ideas of modern revolutionary unionism as exhibited by the I. W. W. may be found in the old International Workingmen's Association.[25] The I. W. W. organ, _The Industrial Worker_, asserts that "we must trace the origin of the ideas of modern, revolutionary unionism to the International."[26] Comparing the French cousin of our modern I. W. W. with the older Association, James Guillaume asks, "et qu'est-ce que la confédération générale du Travail si non la continuation de l'internationale?"[27] Many items in the program originally drafted by the famous anarchist, Michael Bakunin, for the International in 1868 are very similar to the twentieth century slogans of the I. W. W. It began by declaring itself atheist, "_L'alliance se déclare athée_," and went on to assert that its chief work was to be the abolition of religion and the substitution of science for faith. It advocated the political, social and economic equality of the classes, to achieve which end all governments were to be abolished. It opposed not only all centralized organization, but also all forms of political action, and believed that groups of producers, instead of the community, should have control of the processes of industry.[28]
