1928 — Leon Trotsky exiled from the Soviet Union

Trotsky was Lenin’s second-in-command during the Russian Revolution, and later the first leader of the Red Army and a high-ranking Politburo member. But after the death of Lenin in 1924, he lost power and position to Stalin. In 1928, Trotsky was exiled to Alma Ata in Kazakhstan. A year later, he was expelled from the Soviet Union, and sent to Turkey, accompanied by his wife Natalia Sedova and his son Lev Sedov.

His exile marked the end of any serious internal opposition to Stalin in the Soviet Union, with most of his followers either fleeing the country or surrendering. Trotsky continued to advocate his opposition to Stalin from outside the country. A constant thorn in Stalin’s side, he was assassinated in Mexico by a Soviet agent in 1940.
