Bosanska Krajina
During the 1992-95 Bosnian War, Bosanska Krajina was divided between Republika Srpska, the Republic of Bosnia and Herzegovina, and the Autonomous Province of Western Bosnia. The Serb entity of SAO Bosanska Krajina was established in summer 1991. The region was also a place of concentration camps, including Manjača and Omarska where predominantly Bosniaks were held, tortured, raped, and killed.
