thereafter, on February 16, 1963, a new Syrdarya Oblast was established from the parts of the newly acquired agricultural lands of Samarkand and Tashkent regions (the center originally set in Yangiyer, however starting from November 1963 in Gulistan). On February 7, 1964 the Kashkadarya Oblast was restored followed by the Namangan Oblast on December 18, 1967. On June 28, 1971 the Dzhetysay, Kirov and Pakhtaaral rayons of the Syrdarya Oblast of the Uzbek SSR that had very small areas were transferred from to the Chimkent Oblast of the Kazakh SSR. On December 29, 1973 the Jizzakh Oblast was established from the part of the Syrdarya Oblast. Navoi was the last oblast to be established from the parts of the Bukhara and Samarkand oblasts on April 20, 1982. Consequently, as of January 1, 1987, the administrative-territorial division of the Uzbek SSR was as follows: Post 1987 On September 6, 1988, the Jizzakh and Navoi oblasts were abolished. At the same time, the former was merged into the Syrdarya oblast, whereas the latter joined Samarkand. In May 1989, most of the former Navoi Oblast was transferred to the Bukhara Oblast. However, the Jizzakh Oblast was restored in February 1990 followed by the Navoi oblast in 1992. After the Uzbek SSR became independent and turned into the Republic of Uzbekistan, the Karakalpak Autonomous Soviet Socialist Republic was renamed to the Republic of Karakalpakstan. Furthermore, oblasts were renamed into viloyats (English: regions), while rayons became tumans (English: district). In the early 1990s, a number of regions and cities of Uzbekistan that bore Soviet ideological names were renamed. The last (as of 2012) major change in the administrative-territorial division of Uzbekistan was the transfer of the Yangiabad District from the Syrdarya region to Jizzakh in 1999.
