December 1878: Joseph Vissarionovich Dzhugashvili (Stalin) was born.
By 1917 Stalin was given a job of being the leader of one of the Bolshevik parties.
Over time Stalin took more and more responsibility upon himself. He used his role as a secretary to place his supporters in key positions all over the country.
Lenin died in January 1924. After his death there were 2 men standing to take his place: Stalin or Trotsky. The struggle between them lasted 4 years but eventually Stalin got in front of Trotsky. At Lenin's funeral, Stalin made it seem like he had been been very close to Lenin. He even told Totsky the wrong date for Lenin's funeral, therefore Trotsky showed up a day late.
After Stalin became party leader, Trotsky was slowly removed from all of his jobs. In 1928, he was sent to Siberia and in 1929, he was banned from the Soviet Union. Stalin then removed other leading Bolsheviks from their posts to have absolute control. He had become the sole leader of the Soviet Union.
In 1940, Trotsky was murdered by a Stalinist agent who drove the end of an ice-axe into his skull.
