Baron Otto Gustav von Wächter was an Austrian lawyer, Nazi politician and a high-ranking member of the SS, a paramilitary organisation of the Nazi Party. He participated in the Final Solution extermination of Jews in Europe, and was instrumental in creating an SS division consisting of Ukrainians.

The Kraków Ghetto was one of five major metropolitan Nazi ghettos created by Germany in the new General Government territory during the German occupation of Poland in World War II. It was established for the purpose of exploitation, terror, and persecution of local Polish Jews. The ghetto was later used as a staging area for separating the "able workers" from those to be deported to extermination camps in Operation Reinhard. The ghetto was liquidated between June 1942 and March 1943, with most of its inhabitants deported to the Belzec extermination camp as well as to Płaszów slave-labor camp, and Auschwitz concentration camp, 60 kilometres (37 mi) rail distance.
