An Unfinished War: The Historiography of the Organisation of Ukrainian Nationalists and the Ukrainian Insurgent Army Problems

The article analyses the historiographical process related to the history of Ukrainian nationalism, namely the activities of the Organisation of Ukrainian Nationalists and the Ukrainian Insurgent Army in the 1930s–1950s. Drawing on the chronological-terri-torial and conceptual-methodological principles, the authors divide the secondary sources into five main groups: writings by authors of the Ukrainian diaspora, works of Soviet scientists and publicists, post-independence Ukrainian historiography, communist and contemporary Polish historiography, Western history writing. Within each group, key publications are examined through the prism of documentary sources, methodologies, and conceptual approaches, as well as the socio-political context in which they were created.
