“Democracy would be wholly valueless to the proletariat if it were not immediately used as a means for putting through measures directed against private property and ensuring the livelihood of the proletariat.”

“Once the first radical attack on private property has been launched, the proletariat will find itself forced to go ever further, to concentrate increasingly in the hands of the state all capital, all agriculture, all transport, all trade. All the foregoing measures are directed to this end; and they will become practicable and feasible, capable of producing their centralizing effects to precisely the degree that the proletariat, through its labor, multiplies the country’s productive forces.”

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

“The abolition of private property has become not only possible but absolutely necessary. … The outcome can only be the victory of the proletariat.”

Friedrich Engels book Principles of Communism

“In the new-democratic republic under the leadership of the proletariat, the state enterprises will be of a socialist character and will constitute the leading force in the whole national economy, but the republic will neither confiscate capitalist private property in general nor forbid the development of such capitalist production as does not "dominate the livelihood of the people", for China's economy is still very backward.”

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

“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

“In order that the social crisis may bring about the proletarian revolution, it is necessary that, besides other conditions, a decisive shift of the petty bourgeois classes occurs in the direction of the proletariat. This gives the proletariat a chance to put itself at the head of the nation as its leader.”

Leon Trotsky (1879–1940) Marxist revolutionary from Russia

“Dictatorship is rule based directly upon force and unrestricted by any laws. The revolutionary dictatorship of the proletariat is rule won and maintained by the use of violence by the proletariat against the bourgeoisie, rule that is unrestricted by any laws.”

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

“This proposed monopoly of political and economic power [in the form of the Dictatorship of the proletariat] was designed to do many things for the good of humanity, but experience has proven them to be false dreams. For example, the Dictatorship of the Proletariat was designed to spread the enjoyment of wealth among the people by abolishing private property and putting all means of production in the hands of the government. Why did they want to do this? They said it was to prevent all property and wealth from falling into the hands of private capitalists. But what happened when the Communists attempted to do this in Russia? It destroyed what little division of wealth there was and sent the economy hurtling back in the direction of feudalism - an economic system under which a few privileged persons dispense the necessities of life by arbitrary determination while at the same time dictating the way in which all important phases of life shall be lived by the citizens.”

W. Cleon Skousen book The Naked Communist

“How do you think the transition from the present situation to community of Property is to be effected?
The first, fundamental condition for the introduction of community of property is the political liberation of the proletariat through a democratic constitution.”

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

“History has now confronted us with an immediate task which is the most revolutionary of all the immediate tasks confronting the proletariat of any country. The fulfilment of this task, the destruction of the most powerful bulwark, not only of European, but (it may now be said) of Asiatic reaction, would make the Russian proletariat the vanguard of the international revolutionary proletariat. And we have the right to count upon acquiring this honourable title, already earned by our predecessors, the revolutionaries of the seventies, if we succeed in inspiring our movement, which is a thousand times broader and deeper, with the same devoted determination and vigour.”

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