Autonomous republic

The Autonomous Republic of Crimea (Ukrainian: Автоно́мна Респу́бліка Крим) geographically encompasses the major portion of the Crimean peninsula in southern Ukraine. Its capital is Simferopol. The Autonomous Republic of Crimea is the only region within Ukraine that has its own constitution.

On 16 March 2014, after the occupation of Crimea by the Russian military, a referendum on joining the Russian Federation was held. A majority of votes supported the measure. On 21 March 2014, the Russian Duma voted to annex Crimea as a subject into the Russian Federation. The Ukrainian government does not recognize the referendum or annexation of Crimea as legitimate. On 27 March, the UN General Assembly passed Resolution 68/262 by 100 to 11 votes, recognizing the referendum as invalid and denying any legal change in the status of Crimea and Sevastopol.

Oblasts

An oblast (Ukrainian: о́бласть; pl. о́бласті) is on the first level of the administrative division of Ukraine.

Most oblasts are named after their administrative center. Volyn and Zakarpattia, whose respective capitals are Lutsk and Uzhhorod, are named after the historic regions Volhynia and Transcarpathia.

Cities with special status

Two cities have special status (Ukrainian: міста́ зі спеціа́льним ста́тусом): Kyiv and Sevastopol. Their special status puts them on the same administrative level as the oblasts, and thus under the direct supervision of the state via their respective local state administrations, which constitute the executive bodies of the cities. Following the annexation of Crimea by the Russian Federation, Sevastopol is controlled by Russia and is incorporated as a federal subject of Russia.^[10][11]

Raions

Raions (Ukrainian: райо́н; pl. райо́ни) are smaller territorial units of subdivision in Ukraine. There are 136 raions.^[12] Following the December 2019 draft constitutional changes submitted to the Verkhovna Rada by President Volodymyr Zelenskyy, 136 new raions have replaced the former 490 raions of Ukraine.^[13]

Urban districts

An urban district is subordinate to the city administration.^[14]

Hromadas

The territorial hromadas (Ukrainian: територіа́льна грома́да; lit. 'territorial community'), or simlply hromadas (Ukrainian: грома́да) were established by the Government of Ukraine on 12 June 2020 as a part of administrative reform that started in 2015.^[15]

There are three types of hromadas: rural (Ukrainian: сільська́ грома́да), settlement (Ukrainian: се́лищна грома́да) and urban (Ukrainian: міська́ грома́да). There are 1469 hromadas in total (as of November 1, 2023).^[16]

Cossack Hetmanate

The Cossack Hetmanate was divided into military-administrative districts known as regimental districts (polks) whose number fluctuated with the size of the Hetmanate's territory. In 1649, when the Hetmanate controlled both the right and left banks, it included 16 such districts. After the loss of Right-bank Ukraine, this number was reduced to ten. The regimental districts were further divided into companies (sotnias), which were administered by captains (sotnyk).^[17] The lowest division was the kurin.

• Kropyvna Regiment
• Lubny Regiment
• Chyhyryn Regiment
• Chernihiv Regiment
• Nizhyn Regiment

Ukrainian People's Republic

According to the Constitution of the Ukrainian People's Republic, the country was divided into zemlias (lands), volosts and hromadas (communities). This law was not fully implemented as on 29 April 1918 there was the anti-socialist coup in Kyiv, after which Pavlo Skoropadskyi reverted the reform back to the governorate-type administration.^[18]

Soviet Ukraine

Before the introduction of oblasts in 1932, Soviet Ukraine comprised 40 okruhas, which had replaced the former Russian Imperial governorate subdivisions.^[19][20]

In 1932 the territory of the Soviet Ukraine was re-established based on oblasts. At the same time, most of the Western Ukraine at the time formed part of the Second Polish Republic and shared in the Polish form of administrative division based on voivodeships.^[21]
