Lenin and his followers overthrew the Russian czar and began the Russian Revolution.
Explanation:
As Lenin was inspired by the works of Marx and Engels, he led the October Revolution that saw that change in society was only possible violently through revolution by destroying the conditions in which capitalism settled. In this case, the monarchical and quasi-feudal system was reseted and the Czars were executed. Their legacy was eradicated so they would never again retake power. The Communist Party formed new conditions where a state-planned economy formed.
In this Communist system the working class vindicated the social demands establishing the rule of the Proletariat. The means of production, like factories and land, were owned by the state and rationally distributed according to Political Economy principles developed by Lenin and later continued by fellows.
