SAO North-East Bosnia (Serbian: САО Североисточна Босна / SAO Severoistočna Bosna) was a Serb Autonomous Region (Serbian: САО / SAO), a Serb break-away province, in the Yugoslav republic of Bosnia and Herzegovina (SR BiH). It was established in September 1991, proclaimed by the Serb Democratic Party on 19 September 1991, along with other SAOs (Eastern Herzegovina, Bosanska Krajina, Romanija), and included five districts in northeastern SR BiH. It existed between September 1991 and 9 January 1992, when it became part of Republic of the Serb people of Bosnia and Herzegovina (later Republika Srpska). It was renamed SAO Semberija (Serbian: САО Семберија) in November 1991, and SAO Semberija and Majevica (САО Семберија и Мајевица[1]) in December 1991. It included three municipalities (Bijeljina, Lopare and Ugljevik[2]), with a population of 150,000, out of whom 56–59% were ethnic Serbs. The capital was Bijeljina.
