 Several hundred Italians were killed by Josip Broz Tito's resistance movement in September 1943; some had been connected to the fascist regime, while others were victims of personal hatred or the attempt of the Partisan resistance to get rid of its real or supposed enemies.Between 1943 and 1947, the exodus was bolstered by a wave of violence taking place in Istria, known as the "Foibe massacres".Some Italian sources claim these killings amounted to ethnic cleansing, forcing Italians to emigrate.
