Novorossiya (confederation)
Novorossiya or New Russia, also referred to as the Union of People's Republics, was a project for a confederation between the self-proclaimed Donetsk People's Republic (DPR) and the Luhansk People's Republic (LPR) in Eastern Ukraine, both of which were under the control of pro-Russian separatists. The concept of "Novorossiya" emerged in public discourse with the beginning of the Donbas war in eastern Ukraine.
