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, rail distance. Background Before the German-Soviet invasion of 1939, Kraków was an influential centre for the Polish Jews who had lived there since the 13th century. Persecution of the Jewish population of Kraków began immediately after the German troops entered the city on 6 September 1939 in the course of the German aggression against Poland. Jews were ordered to report for forced labour beginning in September 1939. In November, all Jews twelve years or older were required to wear identifying armbands. Throughout Kraków, synagogues were closed and all their relics and valuables confiscated by the Nazi authorities. Kraków was made the capital of the General Government (the part of occupied Poland not directly incorporated into Germany), and by May 1940 the German occupation authority headed by the Governor-General Hans Frank announced that Kraków should become the “racially cleanest" city in the General Government. Massive deportations of Jews from the city ensued. Of the more than 68,000 Jews in Kraków at the time of the German invasion, only 15,000 workers and their families were permitted to remain. All other Jews were ordered out of the city, to be resettled into surrounding rural areas of the General Government. Formation of the Kraków Ghetto In April 1940, Hans Frank proposed the removal of 50,000 Jews from the city of Kraków. Frank's reason for removing Jews from the Jewish quarter was that the area "...will be cleansed and it will be possible to establish pure German neighborhoods..." within Kraków. From May 1940 to 15 August 1940, a voluntary expulsion program was enacted. Jews that chose to leave Kraków were allowed to take all of their belongings and relocate throughout the General-Government (Generalgouvernement). By 15 August 1940, 23,000 Jews had left Kraków. After this date, mandatory expulsions were enforced. On 25 November 1940,
