The political divisions of Bosnia and Herzegovina were created by the Dayton Agreement, which recognized a second tier of government in Bosnia and Herzegovina, comprising two entities: the Federation of Bosnia and Herzegovina (FBiH), with mostly Bosniaks and Croats, and the Republika Srpska (RS) with mostly Serbs – each governing roughly one half of the state's territory. Today, all three ethnic groups have an equal constitutional status over the entire territory of Bosnia and Herzegovina.
