This edited volume focuses on the effects that Russia’s 2022 full-scale invasion of Ukraine had on Central and Eastern Europe (CEE). It includes chapters covering fourteen countries situated in different corners of the broader region. Individual contributions shed light on how these CEE countries positioned themselves vis-à-vis the war and (re)defined their own regional identities and geopolitical belonging. The chapters offer a rich survey of the local discourses and perspectives, grasping the region in its persisting complexity and diversity.
