Serbs of Bosnia and Herzegovina
After the government of the Republic of Bosnia and Herzegovina declared independence, which was not accepted by the federal Serb controlled government of Yugoslavia, the Serbian Autonomous Area of the Bosnian Frontier was formed in the western Bosnian Frontier region of Bosnia and Herzegovina with its capital in Banja Luka, which was not recognised by the central government. SAO Bosnian Frontier made attempts to unite with the Autonomous Region of the Serbian Frontier in Croatia. The Serb political leadership martialled its own force assisted by the Yugoslav People's Army and declared independence from Bosnia and Herzegovina in late 1992.
