Research on the destruction of the Jewish community of Thessaloniki has not dealt with the issue of collaboration with the Germans by members of the city’s Christian population. Their motives were largely financial, as much was to be gained from the movable and immovable Jewish property. This chapter inspects the Holocaust in Thessaloniki as a business opportunity for local collaborators. It examines the careers and ideological and financial motivation of collaborators involved in the Jewish deportations by focusing on two case studies: the service for the disposal of Jewish properties and the demolition and auctioning off the Baron Hirsch quarter. In 1943, the Baron Hirsch quarter in Thessaloniki - chosen because it was located next to the train station - was transformed into a German transit camp where Thessaloniki’s Jews were first forcibly enclosed and then deported. After the last deportation in August 1943, the camp was demolished and the materials auctioned off by both private companies and individuals after obtaining German approval. This chapter sheds light on the local population’s involvement in the deportation of the Jews, and describes the tracing of the postwar fate of the collaborators, which confirms that the Greek justice system paid little or no attention to their deeds.
