“Since 1845 Marx and I have held the view that one of the ultimate results of the future proletarian revolution will be the gradual dissolution of the political organisation known by the name of state. The main object of this organisation has always been to secure, by armed force, the economic oppression of the labouring majority by the minority which alone possesses wealth. With the disappearance of an exclusively wealth-possessing minority there also disappears the necessity for the power of armed oppression, or state power. At the same time, however, it was always our view that in order to attain this and the other far more important aims of the future social revolution, the working class must first take possession of the organised political power of the state and by its aid crush the resistance of the capitalist class and organise society anew. This is to be found already in The Communist Manifesto of 1847, Chapter II, conclusion.
The anarchists put the thing upside down. They declare that the proletarian revolution must begin by doing away with the political organisation of the state. But after its victory the sole organisation which the proletariat finds already in existence is precisely the state. This state may require very considerable alterations before it can fulfil its new functions. But to destroy it at such a moment would be to destroy the only organism by means of which the victorious proletariat can assert its newly-conquered power, hold down its capitalist adversaries and carry out that economic revolution of society without which the whole victory must end in a new defeat and in a mass slaughter of the workers similar to those after the Paris Commune.
Does it require my express assurance that Marx opposed this anarchist nonsense from the first day it was put forward in its present form by Bakunin? The whole internal history of the International Workingmen’s Association is evidence of this. From 1867 onwards the anarchists were trying, by the most infamous methods, to conquer the leadership of the International; the main hindrance in their way was Marx. The five-year struggle ended, at the Hague Congress of September 1872, with the expulsion of the anarchists from the International; and the man who did most to achieve this expulsion was Marx.”
