The state is nothing but an instrument of opression of one class by another - no less so in a democratic republic than in a monarchy.
Friedrich EngelsThe proletariat uses the State not in the interests of freedom but in order to hold down its adversaries, and as soon as it becomes possible to speak of freedom the State as such ceases to exist.
Friedrich EngelsPeople have learned by bitter experience that the "European fraternal union of peoples" cannot be achieved by mere phrases and pious wishes, but only by profound revolutions and bloody struggles; they have learned that the question is not that of a fraternal union of all European peoples under a single republican flag, but of an alliance of the revolutionary peoples against the counter-revolutionary peoples, an alliance which comes into being not on paper, but only on the battlefield.
Friedrich Engels
