Serb Autonomous Regions

Serbs in SFR Yugoslavia in 1981

From August 1990 to November 1991, during the breakup of Yugoslavia, several Serb Autonomous Regions (also known as Serb Autonomous Districts or Oblasts; sing. Serbian: Српска аутономна област [САО], romanized: Srpska autonomna oblast, SAO) were proclaimed by the SDS in the Yugoslav republics of Croatia and Bosnia-Herzegovina in light of the possible secession of the republics from the Socialist Federal Republic of Yugoslavia.

These self-proclaimed Serb-inhabited entities later united within their respective unrecognized republics, forming the Republic of Serbian Krajina in Croatia and Republika Srpska Bosna i Hercegovina in Bosnia and Herzegovina.
