The Turkestan Autonomous Soviet Socialist Republic (initially, the Turkestan Socialist Federative Republic; 30 April 1918 – 27 October 1924) was an autonomous republic of the Russian Soviet Federative Socialist Republic located in Soviet Central Asia.
During the Russian Empire, the Turkestan ASSR's territory was governed as Turkestan Krai, the Emirate of Bukhara, and the Khanate of Khiva. From 1905, Pan-Turkist ideologues like Ismail Gasprinski aimed to suppress differences among the peoples who spoke Turkic languages, uniting them into one government.
National delimitation in Central Asia began in 1924. Upon dissolution, the Turkestan ASSR was split into Turkmen SSR (now Turkmenistan), Uzbek SSR (now Uzbekistan) with the Tajik ASSR (now Tajikistan), Kara-Kirghiz Autonomous Oblast (now Kyrgyzstan), and Karakalpak Autonomous Oblast (now Karakalpakstan).
