In the course of the Second World War, the National Socialist persecution of the Jews in the German Reich and throughout the occupation period, art was stolen to a great extent. In this book, the author systematically describes– in historical as well as juridical terms– the extremely complex subject matter of art theft in the Second World War (so-called“looted art”), in marked contrast to persecution-related dispossession of cultural assents from mostly Jewish provenience. In these frequently sensitive matters concerning the restitution of war-related, expropriated and/or persecution-related, removed cultural assets, questions arising from the realm of (international) private law, the intertemporal law of restitution and indemnification as well as international law are to be answered first and foremost.
