Lenin died and Stalin rose to power.

After the death of Lenin in January 1924, Stalin took control of the party. He started by managing Lenin's funeral. He also contributed to the growing cult of personality by giving lectures all over the country.

Stalin, however, was only one of several people who wanted to become Lenin's successor. Some important ones were Trotsky, Zinoviev, Kamenev, Bukharin, Rykov and Tomsky. Trotsky became Stalin's main obstacle, and he was eventually exiled from the Soviet Union in 1929.
