Historiography of the Volyn tragedy: This article presents the historiography of the Wolyn tragedy as presented by historians in Poland and Ukraine after World War II.  The Massacres of Poles in Volhynia were part of the ethnic cleansing operation in the Polish province of Eastern Galicia and Volhynia (now in western Ukraine) that took place beginning in March 1943 and lasted until the end of 1944.  According to political scientist Nathaniel Copsey, research into this event was quite partisan till 2009 (with some exceptions) and dominated by Polish researchers, some of whom lived there at the time or are descended from those who did.  The most thorough is the work of Ewa and Władysław Siemaszko, the result of years of research conducted with the goal of demonstrating that the Poles were victims of genocide.  Nonetheless, the 45 years of state censorship resulted in an excessive supply of works described as "heavy in narrative", "light in analysis" and "inherently - though perhaps unconsciously - biased against Ukrainians."
