Russia
There were different types of government that Lenin brought to Russia. The main ones were communist and socialist types of government. These governments were ones which were ruled by the Communist Party.
Lenin was concerned about Stalin's concentration of power and his authoritarian tendencies. In his final writings, particularly his "Testament," Lenin warned that Stalin's position as General Secretary could lead to a dangerous centralization of authority that might undermine the principles of the Bolshevik Revolution. He believed Stalin was too ambitious and lacked the necessary diplomatic skills to lead effectively. Lenin ultimately recommended that Stalin be removed from his position to safeguard the future of the Communist Party and the Soviet state.
I believe the communist party! Not certain but I think it was lead by Stalin! Before that it was Vladimir Ilyich Ulianov: Lenin, and his sidekick Lev Bronstein: Trotsky. Lenin died in 1924 & Trotsky was murdered in Mexico in 1940 by Stalins henchmen.
Communist. He wasn't a leader, though. He was selected to be Vladimir Lenin's successor, which would have made him Premier of the Soviet Union if Joseph Stalin didn't usurp the position so he could lead the country. If you want to know more, Wikipedia has a good article on him.
Vladimir Lenin led the Communist movement in Russia. There were other Marxist leaders such as Julius Martov, but they were not as radical as Lenin and did not start the October Revolution that put Lenin and his Bolsheviks (later renamed Communists) in power.

The Bolshevik Party (later renamed the Communist Party) led the Russian Revolution of October 1917. The previous revolution in that year, the February Revolution, was not ed by any particular political party.
The theory of communism was developed in Germany by Karl Marx and Freidrich Engels; based in part on social theories from Plato.However it was in Russia that communists first took power in a country and attempted to govern a nation by communist theory.
