República Socialista Soviética de Turkmenistán
Following the Russian Revolution, Soviet power was fully in place by 1924, when the Turkmen Soviet Socialist Republic was created. The name "Merv" was changed to "Mary" in 1937. The region initially was directly under control of the Turkmen SSR government, but in 1939 Mary "oblast' " (, ) was created. It was abolished in 1963, then re-established in 1970.
