One of the new states created in the process of national delimitation of Soviet Central Asia in October 1924 was the Uzbek Soviet Socialist Republic – Uzbek SSR or Soviet Uzbekistan. Soviet Tajikistan was created at the same time within the predominantly Turkic Uzbek SSR as an Autonomous Soviet Socialist Republic (Tajik ASSR) – one rank below a Soviet Socialist Republic in USSR geopolitical hierarchy. The new autonomous republic included what had been eastern Bukhara and had a population of about 740,000, out of a total population of nearly 5 million in the Uzbek Soviet Socialist Republic as a whole. Its capital was established in Dyushambe, which had been a village of 3,000 in 1920. In December 1929, Tajik ASSR was detached from the Uzbek SSR and given full status as a Soviet Socialist Republic – Tajik Socialist Soviet Republic. At that time, its capital was renamed "Stalinabad", after Joseph Stalin, and the territory that is now northern Tajikistan (Sughd Province) was added to the new republic. Even with the additional territory, the Tajik SSR remained the smallest Central Asian republic. On 5 December 1936, it was renamed to the Tajik Soviet Socialist Republic.
