November 7, 2019 -- Leon Trotsky's revolutionary activity as a young man spurred his first of several ordered exiles to Siberia. He waged Russia's 1917 revolution alongside Vladimir Lenin. As commissar of war in the new Soviet government, he helped defeat forces opposed to Bolshevik control. As the Soviet government developed, he engaged in a power struggle against Joseph Stalin, which he lost, leading to his exile again and, eventually, his murder.
