The Donetsk Oblast (Ukrainian: Донецька область, romanized: Donetska oblast, IPA: [doˈnɛtsʲkɐ ˈɔblɐsʲtʲ]), also referred to as Donechchyna (Ukrainian: Донеччина), is an oblast of eastern Ukraine. Its administrative centre is Donetsk; however, its Regional State Administration has been temporarily relocated to Kramatorsk because of the ongoing Russo-Ukrainian war. Historically, the region has been an important part of the Donbas region. From its creation in 1938 until November 1961, it bore the name Stalino Oblast as Donetsk was then named "Stalino", in honour of Joseph Stalin. As part of the de-Stalinization process, it was renamed after the Siversky Donets river, the main artery of Eastern Ukraine. The oblast is known for its urban sprawl of Donetsk–Makiivka and Horlivka–Yenakiieve and it is often associated with the coal mining industry. The war in Donbas and the subsequent 2022 Russian invasion of Ukraine has seen parts of the oblast come under the control of the self-proclaimed Donetsk People's Republic and Russia, with the administrative center relocated to Mariupol then to Kramatorsk. The oblast is notable for heavy fighting during the Battle of Donbas (2022). On 30 September 2022 Russia annexed the Donetsk (DPR), Luhansk (Luhansk People's Republic), Zaporizhzhia, and Kherson Oblasts. However, the staged referendums and subsequent annexations are internationally unrecognized, and Ukraine still controls much of the province. The United Nations General Assembly subsequently passed a resolution calling on countries not to recognise what it described as an "attempted illegal annexation" and demanded that Russia "immediately, completely and unconditionally withdraw".
