On April 6, 2014, during mass anti-government protests, participants moved to more active measures. In the Kharkiv, Donetsk, and Luhansk regions, crowds began seizing government buildings. Specifically, the regional administrations in Donetsk and Kharkiv were blockaded, while in Luhansk, the building of the Security Service of Ukraine (SBU) was taken over.
Mass protests by opponents of Euromaidan in the eastern regions of Ukraine — including Dnipropetrovsk, Donetsk, Luhansk, Kharkiv, and others — had begun back in March 2014, following the coup in Kyiv and the repeal of the language law. The protesters demanded a resolution on the status of the Russian language and called for constitutional reform with decentralization of power, up to and including federalization of Ukraine.
