Turkestan Autonomous Soviet Socialist Republic, 1918
On 30 April 1918, following the Russian revolution of 1917, the Bolsheviks in Tashkent created the Turkestan Socialist Federative Republic, soon renamed the Turkestan Autonomous Soviet Socialist Republic (ASSR), an autonomous republic of the Russian Soviet Federative Socialist Republic. Its flag, possibly dating from 1919 was plain red with in the upper hoist in yellow, the letters “TASSR” in both Yanga imlâ Arabic lettering (in which Uzbek was written) and Russian Cyrillic. There are versions known, with or without a yellow or white border around the inscription “TCCP“, with or without the Arabic lettering, which would indicate the republic was upgraded from an autonomous to a full republic, but it doesn’t seem this was actually done; the Turkestan ASSR was abolished in 1924 when it was split into ethnic republics.
