Konflikt polsko-ukraiński o Galicję Wschodnią w latach 1918–1919

Polish-Ukrainian relations have a rich, a centuries history, going back to the Middle Ages, but its specific dimension reached during the great changes which brought together the outbreak of the First World War. The development of the national idea of Europe in the second half of nineteenth century, stimulated Ukrainian political wheels to make efforts to obtain autonomy, which had become a prelude to the creation of an independent state. The effect of these changes became proclamation, even by the official end of hostilities in 1918, two Ukrainian states. These events, however, were in constant conflict with the Polish reason of state. Polish political circles stood for the view that the Polish indigenous lands – and as such recognize, among others Eastern Galicia, and Chelmszczyzna and Wolyn – had to be covered by the borders of the Polish state. That position led to a war with the Ukrainians at the turn of October and November 1918. Fierce fighting, a memorial which still remain a numbers of Polish and Ukrainian, mausoleums and cemeteries in the Eastern Galicia, lasting several months.
