An oblast (Ukrainian: область, romanized: oblast, pronounced [ˈɔblɐsʲtʲ] ; pl. області, oblasti) in Ukraine, sometimes translated as region or province, is the main type of first-level administrative division of the country. Ukraine's territory is divided into 24 oblasts, as well as one autonomous republic and two cities with special status. Ukraine is a unitary state, thus the oblasts do not have much legal scope of competence other than that which is established in the Ukrainian Constitution and devolved by law. Articles 140–146 of Chapter XI of the constitution deal directly with local authorities and their competence.
Oblasts are divided into raions, each oblast having from 3 to 8 raions following the July 2020 reform.[1]
In Ukraine, the term oblast denotes a primary administrative division. Under the Russian Empire and into the 1920s, Ukraine was divided between several governorates. The term oblast was introduced in 1932 by Soviet authorities when the Ukrainian SSR was divided into seven oblasts, replacing the previous subdivision system based on okruhas and encompassing 406 raions (districts).[2] The first oblasts were Vinnytsia Oblast, Kyiv Oblast, Odesa Oblast, Kharkiv Oblast, and Dnipropetrovsk Oblast. Soon after that, in the summer of 1932, Donetsk Oblast was formed out of eastern parts of Kharkiv and Dnipropetrovsk oblasts; in the fall of 1932 Chernihiv Oblast was formed on the border of Kyiv and Kharkiv oblasts.
Between 1935 and 1938, there were several newly created and self-governed special border okrugs (okruhas) located along the western border of the Soviet Union in Ukraine and Belarus. Upon liquidation of the okruhas in 1937–1938, Kyiv, Vinnytsia, Odesa, and Kharkiv oblasts were each split into four additional oblasts (Zhytomyr Oblast, Kamianets-Podilsky Oblast (later Khmelnytskyi), Mykolaiv Oblast, Poltava Oblast). Just before World War II, the Donetsk Oblast was split into Stalino Oblast and Voroshylovhrad Oblast and the Kirovohrad Oblast was created out of portions of Kyiv, Mykolaiv and Odesa oblasts.
During World War II, Ukraine added eight more oblasts of the West Ukraine and Bessarabia. Upon the occupation of Ukraine by Nazi Germany the territory was split between General Government, Kingdom of Romania and Reichskommissariat Ukraine and carried out a completely different administrative division, see Reichskommissariat Ukraine. With the re-establishing of Soviet power in the state after the war, the administrative division by oblast resumed, adding one more oblast—Zakarpattia. In 1954, the Crimean Oblast was transferred from the Russian Soviet Federative Socialist Republic to the Ukrainian SSR; parts of the surrounding oblasts were incorporated into the Cherkasy Oblast, while Izmail Oblast was absorbed by Odesa Oblast. In 1959, Drohobych Oblast was merged with Lviv Oblast.
Most of Ukraine's oblasts are named after their respective administrative centers, which are also the largest and most developed cities in the region. Oblast populations range from 904,000 in Chernivtsi Oblast to 4.4 million in the eastern Donetsk Oblast.
The Ukrainian constitution establishes Ukraine as a unitary state. The specific text of the constitution that refers to the territorial structure is as follows.
The territorial structure of Ukraine is based on the principles of unity and indivisibility of the state territory, the combination of centralisation and decentralisation in the exercise of state power, and the balanced socio-economic development of regions that takes into account their historical, economic, ecological, geographical and demographic characteristics, and ethnic and cultural traditions.
— Constitution of Ukraine, Chapter IX: Territorial Structure of Ukraine, Article 132
Each of Ukraine's oblasts has its own legislative and executive authority, most of which is subordinate to the central government authorities in Kyiv. Each region is administered under laws passed by the Ukrainian government and the Constitution of Ukraine. Each region levies its own taxes and, in return, receives a portion of its budget from Kyiv, which gives them a portion of the taxes it levies.[3]
Executive power in each of the oblasts (as well as in other subdivisions of Ukraine) is exercised by local elected administrations.[4]<
