The communist party had large support since the current government wasn't doing too well economically. Lenin was the first leader of the new government of Russia. A policy created by Lenin was called the New Economic Plan. The NEP made it so that the state would own the heavy industries. This plan would stabilize the economic problem of the time. Stalin created the Five Year Plan. The plan was to quickly industrialize Russia, (Russia at the time was very far behind in industrializing), introduce socialised farming. Eliminated private ownership and to develop education and transport. The plan had succeeded at the cost of many lives and allowed Russia to catch up with the other world powers in industry.
