The Communist Manifesto gives a general summary of history, which compels us to regard the state as the organ of class rule and leads us to the inevitable conclusion that the proletariat cannot overthrow the bourgeoisie without first winning political power, without attaining political supremacy, without transforming the state into the “proletariat organized as the ruling class”; and that this proletarian state will begin to wither away immediately after its victory because the state is unnecessary and cannot exist in a society in which there are no class antagonisms.
