Joseph Stalin, Grigory Zinoviev and Lev Kamenev had led the Soviet Union while Lenin was disabled shortly before his death and immediately after his death. Over the next few years, Stalin eliminated all his rivals, including Leon Trotsky, his main rival. Staling then expelled even Zinoviev and Kamenev and had them shot. Stalin became sole ruler in 1929 but he still answered to the Central Committee of the Communist Party which could have removed him from power. It wasn't until about 1932 when Stalin had everyone who could have stood in his way eliminated that he became the dictator he is known as today.
After Lenin's death leadership of the communist government was in the hhands of a triumvirate of Joseph Stalin, Grigory Zinoviev and Lev Kamenev for a number of years. Yet even they were answerable to the Central Committee of the Communist Party.
Stalin managed to get rid of Zinoviev and Kamenev and took sole power in 1928. He did not become a full dictator until 1932, because the Politburo of the Central Committee of the Communist Party still had enough old Bolsheviks on it who could have voted Stalin out and replaced him.
Stalin got rid of them too leaving mostly his own appointees and others loyal to him on the Politburo and Central Committee. He also then had full control of the OGPU, the secret police, who could eliminate anyone at anytime as Stalin desired with no objections from the Party.
