The essay concerns the events that involved Jewish-owned artistic heritage in the Operational Zone of the Adriatic Littoral (OZAK, 1943-1945). Established in September 1943 by the Germans after the occupation of Italy, the OZAK included the province of Trieste, where the Nazi racial laws were applied. This implied the seizure of all Jewish assets, including art collections. As evidence of these facts, the cases of the families Brunner, Morpurgo and Pincherle are explained and reconstructed thanks to archival sources, emblematic examples of the different paths that Jewish cultural heritage could have taken.
