Poland’s Institute of National Remembrance (IPN) has announced a new series focused on the ideology of Ukrainian nationalists. The IPN states this initiative will address the role of these nationalists in crimes committed against Poles during World War II. The first installment will center on Dmytro Dontsov, a key figure in Ukrainian nationalist thought. This announcement follows a recent dispute with Ukraine regarding historical memory and interpretations of events during the war. The IPN aims to explore the ideological foundations of actions that resulted in Polish casualties. The project intends to provide a detailed examination of this controversial period in history. This move is likely to further strain relations between Poland and Ukraine, already impacted by differing historical narratives.
