Analysis of information sources in references of the Wikipedia article "Schimbul de populație între Polonia și Ucraina sovietică" in Romanian language version.
The formal acceptance of the historical Curzon Line as the boundary demarcating the new frontier between Poland and the Union of Soviets Socialist Republics led to a massive population exchange between the two countries during the final years of World War II and its aftermath. The process of population exchange began immediately with the signing of the Polish-Soviet agreement of September 1944, which set the new frontiers. A program of resettlement which targeted communities on both sides of the new border affected some 1.4 million individuals, including 810,000 Polish inhabitants of former East Galicia and Volhynia and 630,000 individuals identified with the Ukrainian ethnolinguistic community inhabiting the borderlands of Podlachia, Chelm, Jaroslaw, and the Lemko region. This article specifically discusses the population transfer and resettlement that took place in these Trans-Curzon territories during 1944-49.
