Serbian Autonomous Regions
During the Yugoslav Wars, the Serbian Autonomous Regions, (Serbian: Српска аутономна област, Srpska autonomna oblast, SAO) were regions in the Yugoslav republics of SR Croatia and SR Bosnia and Herzegovina that the ethnic Serbs proclaimed to be autonomous and subsequently voted for independence. The SAOs would eventually form the Republic of Serbian Krajina in Croatia and the Republika Srpska in Bosnia and Herzegovina.
