leader of Bolshevik party took control of Russia
After Vladimir Lenin seized control of Russia in 1917, the nation turned to communist values. The government took all the land from private ownership and put it work as a government entity.
Control of Russia passed to Joseph Stalin, Lev Kamenev and Gregory Zinoviev acting together. Gradually, Stalin ousted the others and took complete control by 1929.
When Lenin took control of the Russian government he canceled all of Russia's debts with two purposes in mind. One was to basically save the cost of repaying foreign loans. The second purpose was to declare, according to Lenin, Russia's independence from imperialist oppression. Additionally, it was a statement that Russia would control its own economic future.
