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.
