From 1995 until 2000, the majority of the current-day Brčko District was under the temporary authority of Republika Srpska, one of the two entities of Bosnia and Herzegovina, as one of its municipalities. Following the final arbitration award, Brčko District was constituted in 2000 under the direct sovereignty of the state, formally held in condominium by both entities, united based on the boundaries of the pre-war Brčko municipality, with the Mayor having authority over the entire District.
