Modern Industrial society in specific is characterized by class conflict between the bourgeoisie and proletariat. However, the productive forces of capitalism are quickly ceasing to be compatible with this exploitative relationship. Thus, the proletariat will lead a revolution. However, this revolution will be of a different character than all previous ones: previous revolutions simply reallocated property in favor of the new ruling class. However, by the nature of their class, the members of the proletariat have no way of appropriating property. Therefore, when they obtain control they will have to destroy all ownership of private property, and classes themselves will disappear.
At the 5th World Congress of the Comintern in July 1924, Zinoviev condemned Marxist philosopher Georg Lukács 's History and Class Consciousness , published in 1923 after his involvement in Béla Kun 's Hungarian Soviet Republic , and Karl Korsch 's Marxism and Philosophy . Zinoviev himself was dismissed in 1926 after falling out of favor with Stalin. Bukharin then led the Comintern for two years, until 1928 when he too fell out with Stalin. Bulgarian Communist leader Georgi Dimitrov headed the Comintern in 1934 and presided until its dissolution.
