This article recounts a little-known episode in which Yugoslav partisans, led by the Communist Party of Yugoslavia, rescued some 2,500 Jews from the former Italian camp for Jews in the northern Adriatic in the autumn of 1943. By focusing on this historical event, the article argues for broadening the notion of rescue of Jews during the Holocaust. Rather than locating ‘rescue’ in the motivations of individuals, the article takes as a point of departure the collective aspect of rescue and investigates the importance of the ideological considerations of the Communist Party of Yugoslavia in its decision to rescue the Jews. Rather than in abstract ethical notions, the partisan rescue of the Jews was rooted in their political vision of the future socialist federation, of which the Jews were part.
