NTD of the area along ethnic lines had been proposed as early as 1920. At this time Central Asia consisted of two Autonomous Soviet Socialist Republics (ASSRs) within the Russian SFSR: the Turkestan ASSR, created in April 1918 and covering large parts of what are now southern Kazakhstan, Uzbekistan and Tajikistan, as well as Turkmenistan), and the Kirghiz Autonomous Soviet Socialist Republic (Kirghiz ASSR, Kirgizistan ASSR on the map), which was created on 26 August 1920 in the territory roughly coinciding with the northern part of today's Kazakhstan (at this time Kazakhs were referred to as ‘Kyrgyz’ and what are now the Kyrgyz were deemed a sub-group of the Kazakhs and referred to as ‘Kara-Kyrgyz’ i.e. ‘black Kyrgyz’). There were also the two separate successor ‘republics’ of the Emirate of Bukhara and the Khanate of Khiva, which were transformed into the Bukhara and Khorezm People's Soviet Republics following the takeover by the Red Army in 1920.
