Soviet Central Asia
Soviet Central Asia (, "Sovetskaya Srednyaya Aziya") refers to the section of Central Asia formerly controlled by the Soviet Union, as well as the time period of Soviet administration (1918–1991). Central Asian SSRs declared independence in 1991. In terms of area, it is nearly synonymous with Russian Turkestan, the name for the region during the Russian Empire. Soviet Central Asia went through many territorial divisions before the current borders were created in the 1920s and 1930s.
