What was the difference between Lenin's idea of communism in Russia and Marx's idea of evolution of communism?

Answer 1

There really wasn't a "difference"... Lenin more so supplemented the theory, rather than changing it. Lenin [and Stalin] strongly warned against revisionism. (Revisionism is the changing of the theory, often for personal benefit..)

The above is not totally correct:

There were several differences between the two. Marx believed in and economic revolution which would result in a change in the political system. Lenin believed in a political revolution which would then result in a change in the economic system.

Lenin and his Bolsheviks overwhelmed the Provisional Government after the abdication of the Tsar and impose rule by the soviets in various cities. The Bolsheviks then changed the economy into a predominantly socialistic one.

In addition, Marx believed that the revolution could take place only in the heavily industrialized nations where capitalism flourished to the point where the bourgeoisie and proletariat social classes drifted further and further apart until the proletariat would overwhelm the bourgeoisie. The proletariat would then change the existing government into what he called the Dictatorship of the proletariat. Lenin believed that the revolution could take place in a predominantly agrarian society where the majority of the population was peasant farmer rather than industrialized workers.

Marx believed capitalism would die of its own defects because the proletariat would overthrow the bourgeoisie and take over ownership and control of the means of production. Lenin believed capitalism had to be killed.

Marx believed that the revolution would be by a general mass of the proletariat practically without organization. Lenin believed the revolution could only happen by a small group of professional revolutionaries
