Unidentified human remains discovered within Polish territory: Traces of the difficult history of the twentieth century.

Poland, due to its geographical location, has been a place where the interests of neighbouring countries have converged. As a result, Polish territory has been the site of hostilities, totalitarian terror, and acts of genocide. Following the end of World War II, Poland became part of the so-called Eastern Bloc. A movement known as the anti-communist underground arose within Polish territory with the aim of conducting partisan warfare and political and propaganda activities against the occupiers. Partisans were victims of campaigns of liquidation; they lost their lives during interrogations, died in prisons, were sentenced to death by Polish courts, and were subsequently buried at unknown sites throughout the country. In connection with war and post-war events within Polish territory, the remains of victims of both World War II and post-war political repressions are being found to this day. In addition, remains derived from historical populations are being discovered as well as present-day remains belonging to missing persons or victims of criminal offences. A portion of the remains resulting from military operations and the post-war history of Poland are discovered by chance, but discovery of the burial sites of victims of communist crimes is often preceded by many years of research. International agreements and Polish legal regulations make it possible to search for victims of armed conflicts of various nationalities within the country. The process of identifying victims of armed conflicts, political terror and genocide can be carried out thanks to routine procedures for handling unidentified remains. Given the diversity (various historical periods, various nationalities) of the discovered remains, the elaborated procedures enable their dignified burial.
