The study of English capitalism convinced Marx of the truthfulness of certain generalizations which he had already begun to formulate in 1844. It became more and more evident to him that economic facts, to which history had hitherto attributed no role or a very inferior one, constituted, at least in the modern world, a decisive historic force. "They form the source from which spring the present class antagonisms. These antagonisms in countries where great industry has carried them to their complete development, particularly in England, are the bases on which parties are founded, are the sources of political struggles, are the reasons for all political history."[3] Although Marx had arrived at this opinion earlier and had generalized this point of view in "French-German Annals," his study of English economics swept away any possible doubt that "in general it was not the State which conditions and regulates civil society, but civil society which conditions and regulates the State, that it was then necessary to explain politics and history by economic relations, and not to proceed inversely."[4] "This discovery which revolutionized historical science was essentially the work of Marx," says Engels, and, with his customary modesty, he adds: "The part which can be attributed to me is very small. It concerned itself directly with the working-class movement of the period. Communism in France and Germany and Chartism in England appeared to be something more than mere chance which could just as well not have existed. These movements became now a movement of the oppressed class of modern times, the working class. Henceforth they were more or less developed forms of the historically necessary struggle which this class must carry on against the ruling class, the bourgeoisie. They were forms of the struggle of the classes, but which were distinguished from all preceding struggles by this fact: the class now oppressed, the proletariat, cannot effect its emancipation without delivering all society from its division into classes, without freeing it from class struggles. _No longer did Communism consist in the creation of a social ideal as perfect as possible; it resolved itself into a clear view of the nature, the conditions, and the general ends of the struggle carried on by the working class._"[5]
