“The bourgeoisie has gained a monopoly of all means of existence in the broadest sense of the word. What the proletarian needs, he can obtain only from this bourgeoisie, which is protected in its monopoly by the power of the state. The proletarian is, therefore, in law and in fact, the slave of the bourgeoisie, which can decree his life or death.”

“The bourgeoisie … lets him have the appearance of acting from a free choice, of making a contract with free, unconstrained consent, as a responsible agent who has attained his majority. Fine freedom, where the proletarian has no other choice than that of either accepting the conditions which the bourgeoisie offers him, or of starving, of freezing to death, of sleeping naked among the beasts of the forests!”

Friedrich Engels (1820–1895) German social scientist, author, political theorist, and philosopher

“Until the bourgeoisie is completely vanquished, until its wealth has been confiscated, the proletariat must without fail possess a military force, it must without fail have its "proletarian guard," with the aid of which it will repel the counter-revolutionary attacks of the dying bourgeoisie, exactly as the Paris proletariat did during the Commune.”

Joseph Stalin (1879–1953) General secretary of the Communist Party of the Soviet Union

“The proletariat needs state power, a centralized organisation of force, an organisation of violence, both to crush the resistance of the exploiters and to lead the enormous mass of the population - the peasants, the petty bourgeoisie, and semi-proletarians - in the work of organising a socialist economy.”

Vladimir Lenin book The State and Revolution

“The State is a machine in the hands of the ruling class for suppressing the resistance of its class enemies. in this respect the dictatorship of the proletariat does not differ essentially from dictatorship of any other class, for the proletarian State is a machine for the suppression of the bourgeoisie.”

Joseph Stalin (1879–1953) General secretary of the Communist Party of the Soviet Union

“The proletariat needs state power, the centralized organization of force, the organization of violence, for the purpose of crushing the resistance of the exploiters and for the purpose of leading the great mass of the population - the peasantry, the petty bourgeoisie, the semi-proletarians - in the work of organizing a socialist economy.”

Vladimir Lenin (1870–1924) Russian politician, led the October Revolution

“The class of the wholly propertyless, who are obliged to sell their labor to the bourgeoisie in order to get, in exchange, the means of subsistence for their support. This is called the class of proletarians, or the proletariat.”

Friedrich Engels (1820–1895) German social scientist, author, political theorist, and philosopher

“The correctness of the so-called materialistic conception of history, which considers the political development as dependent on the economic, cannot be brought more strikingly and convincingly to the mind than by the change which in the course of the Nineteenth century has been wrought in the bourgeoisie. It can be demonstrated with the greatest precision how with the change in the productive relations a change of political view and attitude has taken place in the bourgeoisie. Every step forward in economic development has been a step forward in the development of class antagonisms and a step in the approach of the bourgeoisie towards its old enemies, the landlords and priests, and a step in drawing away from the rising proletariat, which in order to effect its emancipation, must advocate equal rights for all men and the democratic principles formerly supported by the bourgeoisie. The moment the proletariat steps forth as a class separate from the bourgeoisie and having interests opposed to it, from that moment the bourgeoisie ceased to be democratic.”

Wilhelm Liebknecht (1826–1900) German socialist politician

“The basic contradiction the great proletarian Cultural Revolution is trying to resolve is the one between the proletariat and the bourgeoisie, between the proletarian and bourgeois roads. The main point of the movement is to struggle against the capitalist roaders in authority in the party.”

Mao Zedong (1893–1976) Chairman of the Central Committee of the Communist Party of China

“The slave is sold once and for all; the proletarian must sell himself daily and hourly. The individual slave, property of one master, is assured an existence, however miserable it may be, because of the master’s interest. The individual proletarian, property as it were of the entire bourgeois class which buys his labor only when someone has need of it, has no secure existence. This existence is assured only to the class as a whole.”

Friedrich Engels (1820–1895) German social scientist, author, political theorist, and philosopher
