Crimea became part of the Russian Empire in 1783, when the Crimean Khanate was annexed, then became part of the Russian Soviet Federative Socialist Republic until 1954. During the first stages of the Russian Civil War there were a series of short-lived independent governments (Crimean People's Republic, Crimean Regional Government, Crimean SSR) but they were followed by White Russian governments (General Command of the Armed Forces of South Russia and later South Russian Government). In October 1921, the Crimean Autonomous Soviet Socialist Republic of the Russian SFSR was instituted. After the Second World War and the subsequent deportation of all of the indigenous Crimean Tatars, the Crimean ASSR was stripped of its autonomy in 1946 and was downgraded to the status of an oblast of the Russian SFSR.
