Marchlewszczyzna was a Polish National District in the Ukrainian Soviet Socialist Republic created as an experiment and as part of the Soviet korenizatsia campaign in Zhytomyr Okruha to the west of Zhytomyr on 21 July 1925 by resolution of the Little Presidium of the All-Ukrainian Central Executive Committee. Its capital, the town of Dovbysh, was renamed later in 1926 as Marchlewsk. The district was one of 32 other national districts that were created in the Ukrainian SSR during that period (1924-1939). Creation of the district was based on standards adopted by the fourth session of the All-Ukrainian Central Executive Committee and recommendations of the Central Commission in affairs of National Minorities at that executive committee. It was created to implement an idea in creation of Polish national districts on territories of Ukrainian and Belarusian SSRs.
The administrative divisions of Ukraine are under the jurisdiction of the Ukrainian Constitution. Ukraine is a unitary state with three levels of administrative divisions: 27 regions, 136 raions (districts) and 1469 hromadas.
An oblast 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.
