This issue features the fourth installment in a series of special sections on the memory of the Organization of Ukrainian Nationalists (OUN) and the OUN-Bandera-wing’s military arm, the Ukrainian Insurgent Army (Ukrainian abbreviation: UPA). Within this series, historians and social scientists detail findings from their research on interwar and war-time Ukrainian nationalism as well as its contemporary public and scholarly interpretations and representations-not least, against the background of the Russian-Ukrainian war (2014-ongoing) and its related propaganda campaigns. In this issue, we also launch a series of special sections in which scholars in the fields of comparative fascism, East European right-wing extremism, and Ukrainian ultra-nationalism debate different approaches to the OUN.
