The nature of Ukrainian-Polish confl icts of the 19th and the fi rst half of the 20th century in the Right-bank Ukraine has been analysed. It was emphasized that by the end of World War I, these were confl icts mostly of an ethno-social nature. In the interwar period, they were just as important as the ethno-political confl icts on the territory of East Galicia and especially Volyn, which had been annexed to the Second Polish Republic. In the author’s judgment, the abovementioned requires a deeper unconventional approach to researching the reasons of the so called Volyn Tragedy of 1943–1944.
