Abstract: During World War II, Bosnia and Hercegovina was occupied by the Ustashe-led Independent State of Croatia, a Nazi collaborator par excellence. Ustashe, mostly Croats, Muslims-Bosniaks, and domestic Germans, overwhelmingly participated in the annihilation of more than 85 % of the Bosnian Jewish population during the Shoah. Beside the physical destruction of the community, these Nazi collaborators plundered Jewish assets in an estimated value of over one billion US dollars and robbed priceless cultural artifacts along with the communal archives. While witness accounts agree that looting of most movable property (books, artwork, and other valuables) was carried out in the first days of occupation by the Nazis themselves, the robbery of Jewish property (apartments, houses, businesses) as well as torture and killings of domestic Jews was committed by the Ustashe. What complicates the restitution in this country is the state and memory politics, but also the inexistence of a central registry of stolen items that could be claimed. Moreover, it is of the essence that the GLAM institutions (galleries, libraries, archives, and museums) within Bosnia and the former Yugoslavia region engage in conducting detailed provenance research of their respective collections.
