the winter of 1942/1943 the Partisans established the Republic of Bihać in Bosanska Krajina. Soon afterwards, Bosanska Krajina was also the place of historical agreements that have taken place in Jajce and Mrkonjić Grad in 1943, ones that established the Republic of Bosnia and Herzegovina in its current borders, as well as the Federation of Yugoslavia. Bosnian War 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 Bosniaks were held, tortured, raped, and killed. Demography The population of the region numbered almost one million before the Bosnian War.

This poverty was a contributing factor to 1950 Cazin Uprising against the communist government, the only such uprising in post-war Bosnia and Herzegovina and Yugoslavia. The later economic boom and prosperity of Bosanska Krajina was mostly due to planned urban development programs that were created specifically for this region in early and mid-1970s by Urban Institute in Banja Luka. The development was further stimulated by the simplification of the banking system that encouraged investments in resource processing industry. As a result, the region has seen a boom in agricultural and industrial production. Agrokomerc, a food manufacturing industry located in northwest region was the largest food manufacturer in Bosnia and Herzegovina and former Yugoslavia. Other industries included chemical industry Saniteks in Velika Kladuša, electronics industry Rudi Cajevec in Banja Luka, Textile industry Sana in Bosanski Novi as well as a range of wood and food processing companies that stimulated an economic boom in this region. There was also a significant ore industry developed around the Kozara Mountain. Transport and aviation The expressway E-661 (locally known as M-16) leads north to Croatia, existing as an expressway from Banja Luka to Laktaši and as a two-lane road from Laktaši to the Bosnian/Croatian border.
