The Article 68 of the constitution of Uzbekistan defines: Divisions The top level is formed by the regions (, plural viloyatlar), the autonomous republic of Karakalpakstan and the independent city of Tashkent. The regions Karakalpakstan and Tashkent are further divided into districts (, plural tumanlar) and cities of regional subordination. The districts are divided into cities of district subordination, urban-type settlements () and citizen assemblies of villages (). , there is one autonomous republic, 12 regions and one independent city: Of the 120 cities, one is of republican subordination (Tashkent), 31 are of regional subordination and 88 are of district subordination. There are 1,067 urban-type settlements. History Pre-history Before the October Revolution, the territory of modern Uzbekistan was divided between the Trans-Caspian, Samarkand, Syrdarya, and Ferghana regions of the Russian Empire, as well as between its vassal possessions—the Bukhara Emirate and the Khanate of Khiva. After the establishment of Soviet power in Turkestan in 1918, the territory of present-day Uzbekistan (except for the territories of the Bukhara Emirate and the Khiva Khanate) was merged into the Turkestan ASSR with a center set in Tashkent. In 1920, Soviet power was established in Bukhara and Khiva, which lead to the Bukhara and Khorezm People's Republics being established. Later, the Khorezm People's Soviet Republic was transformed into Soviet Socialist Republic on October 30, 1923 followed by the establishment of the Bukhara People's Soviet Socialist Republic on September 19, 1924. On September 16, 1924, an extraordinary session of the Central Electoral Commission of the Turkestan ASSR ruled to go forward with the national-state delimitation. This implied the establishment of the Uzbek SSR as part of the USSR. It comprised part of the lands of the former Samarkand, Semirechye and Ferghana Oblasts, as well as the Bukhara and Khorezm SSRs abolished at that time. This decision was put forward by the 2nd session of the All-Russian Central Executive Committee on October 14, 1924 and later approved by the 12th All-Russian Congress of Soviets on May 11, 1925. The date of foundation of the Uzbek SSR is considered October 27, 1924. Its center became Samarkand. Moreover, the Tajik Autonomous Soviet Socialist Republic was formed as part of the Uzbek SSR. 1924–1938 In 1925, oblasts were introduced in the Uzbek SSR. The oblasts were dividend into uyezds, and those, in turn, were divided into volosts. As
