"In the two revolutionary years of 1848-49 the League proved itself in two ways. First, its members everywhere involved themselves energetically in the movement and stood in the front ranks of the only decisively revolutionary class, the proletariat, in the press, on the barricades and on the battlefields. The League further proved itself in that its understanding of the movement, as expressed in the circulars issued by the Congresses and the Central Committee of 1847 and in the Manifesto of the Communist Party, has been shown to be the only correct one, and the expectations expressed in these documents have been completely fulfilled."

Section II has made clear the relations of the Communists to the existing working-class parties, such as the Chartists in England and the Agrarian Reformers in America. The Communists fight for the attainment of the immediate aims, for the enforcement of the momentary interests of the working class; but in the movement of the present, they also represent and take care of the future of that movement. In France, the Communists ally with the Social Democrats¹against the conservative and radical bourgeoisie, reserving, however, the right to take up a critical position in regard to phases and illusions traditionally handed down from the Great Revolution. In Switzerland, they support the Radicals, without losing sight of the fact that this party consists of antagonistic elements, partly of Democratic Socialists, in the French sense, partly of radical bourgeois.
