Background
Donbas refers to the coal and steel heartland of eastern Ukraine, encompassing Donetsk and Luhansk oblasts. Russia has declared the annexation of both, though as of April 2026 it does not fully control either. On 1 April 2026, Russia announced the 'completion of the liberation of the Luhansk People's Republic', despite more than 99% of Luhansk Oblast having been under Russian control since the 2022 formal annexation. Russia simultaneously communicated via US intermediaries that it intends to seize all of Donbas within two months.
The region has been a theatre of conflict since 2014, when Russian-backed separatists seized territory in both oblasts. The full-scale invasion of February 2022 brought Russian forces deep into Donetsk Oblast, though Ukrainian defences have slowed advances around Pokrovsk, Chasiv Yar, and the Fortress Belt. ISW assessed on 31 March 2026 that Russia is unlikely to seize the Fortress Belt area in 2026.
Donbas contains significant industrial infrastructure including steel mills, coalmines, and chemical plants, much of it destroyed or non-functional since 2022. Ukraine retains control of the western portions of Donetsk Oblast, including Pokrovsk and Sloviansk. Russia's stated objective of full Donbas control remains the political frame around which Ceasefire negotiations are structured.
