Republika Srpska is one of two constitutional and legal entities of Bosnia and Herzegovina, the other being the Federation of Bosnia and Herzegovina. The entities are largely autonomous.
The territory of what is Republika Srpska was first inhabited by several Illyrian and Celtic civilizations during the Neolithic age. After centuries of Ottoman and Austro-Hungarian rule, it became part of the Kingdom of Serbs, Croats and Slovenes in 1918 following World War I, which was renamed to Yugoslavia in 1929. Following World War II in Yugoslavia, it became part of the second Yugoslavia in 1945 as part of the Socialist Republic of Bosnia and Herzegovina. The creation of the modern Republika Srpska in 1991 was declared from six Serb Autonomous Regions during the Yugoslav Wars. It became an internationally recognized subject within the state of Bosnia and Herzegovina in 1995.
Since the end of the war and the implementation of the Dayton Agreement, Republika Srpska maintains its unicameral parliamentary system and maintains a free economy similar to the rest of the country.
