From the end of February 2014, in the aftermath of the Euromaidan and the Revolution of Dignity, which resulted in the ousting of Russian-leaning Ukrainian President Viktor Yanukovych, demonstrations by Russian-backed, pro-Russian, and anti-government groups took place in major cities across the eastern and southern regions of Ukraine. The unrest, which was supported by Russian military and intelligence, belongs to the early stages of the Russo-Ukrainian War.

Euromaidan, or the Maidan Uprising, was a wave of demonstrations and civil unrest in Ukraine, which began on 21 November 2013 with large protests in Maidan Nezalezhnosti in Kyiv. The protests were sparked by President Viktor Yanukovych's sudden decision not to sign the European Union–Ukraine Association Agreement, instead choosing closer ties to Russia and the Eurasian Economic Union. Ukraine's parliament had overwhelmingly approved of finalizing the Agreement with the EU, but Russia had put pressure on Ukraine to reject it. The scope of the protests widened, with calls for the resignation of Yanukovych and the Azarov government. Protesters opposed what they saw as widespread government corruption, abuse of power, human rights violations, and the influence of oligarchs. Transparency International named Yanukovych as the top example of corruption in the world. The violent dispersal of protesters on 30 November caused further anger. Euromaidan led to the 2014 Revolution of Dignity.
