Erich Julius Eberhard von dem Bach-Zelewski was a high-ranking SS commander of Nazi Germany of Kashubian-Polish origin. During World War II, he was in charge of the Nazi security warfare against those designated by the regime as ideological enemies and any other persons deemed to present danger to the Nazi rule or Wehrmacht's rear security in the occupied territories of Eastern Europe. It mostly involved atrocities against the civilian population. In 1944, he led the brutal suppression of the Warsaw Uprising. Despite his responsibility for numerous war crimes and crimes against humanity, Bach-Zelewski did not stand trial in the Nuremberg trials, and instead appeared as a witness for the prosecution. He was later convicted for politically motivated murders committed before the war and died in prison in 1972.

Auschwitz concentration camp was a complex of over 40 concentration and extermination camps operated by Nazi Germany in occupied Poland during World War II and the Holocaust. It consisted of Auschwitz I, the main camp (Stammlager) in Oświęcim; Auschwitz II-Birkenau, a concentration and extermination camp with gas chambers; Auschwitz III-Monowitz, a labour camp for the chemical conglomerate IG Farben; and dozens of subcamps. The camps became a major site of the Nazis' Final Solution to the Jewish question.
