All the other large and small nationalities and peoples are destined to perish before long in the revolutionary world storm. The next world war will result in the disappearance from the face of the earth not only of reactionary classes and dynasties, but also of entire reactionary peoples. And that, too, is a step forward.
Friedrich EngelsWhat is Communism? Communism is the doctrine of the conditions of the liberation of the proletariat. What is the proletariat? The proletariat is that class in society which lives entirely from the sale of its labor and does not draw profit from any kind of capital; whose weal and woe, whose life and death, whose sole existence depends on the demand for labor.
Friedrich EngelsWe find two great gangs of political speculators, who alternately take possession of the state power and exploit it by the most corrupt ends -- the nation is powerless against these two great cartels of politicians who are ostensibly its servants, but in reality dominate and plunder it.
Friedrich EngelsBy bourgeoisie is meant the class of modern capitalists, owners of the means of social production and employers of wage labor. By proletariat, the class of modern wage laborers who, having no means of production of their own, are reduced to selling their labor power in order to live.
