Its name is very likely linked to the Breuci (Greek Βρεῦκοι), one of the Pannonian tribes of the Illyrians who migrated to the vicinity of today's Brčko from the territories of the Yamnaya culture in the 3rd millennium BC. Breuci greatly resisted the Romans but were conquered in 1st century BC and many were sold as slaves after their defeat. They started receiving Roman citizenship during Trajan's rule.
The city is on the north, riparian border of Bosnia, across the Sava River from the village of Gunja in Croatia.
Brčko is the seat of the Brčko District, an independent unit of local self-government created on the territory of Bosnia and Herzegovina following an arbitration process. The local administration was formerly supervised by an international supervisory regime headed by Principal Deputy High Representative who is also ex officio the Brčko International Supervisor. This international supervision was frozen since 23 May 2012.[4]
Brčko was a geographic point of contention in 1996 when the U.S.-led Implementation Force (IFOR) built Camp McGovern between the villages of Brod and Brka. Camp McGovern under the overwatch of 3-5 CAV 1/BDE/1AR Division (US) was constructed from a war torn farming cooperative structure in the Zone of Separation (ZOS) for the purpose of establishing peacekeeping operations. The mission was to separate the forming warring factions. The ZOS was one kilometer wide of no man's land, where special permission was required for Serbian or Bosnian forces to enter. Various checkpoints and observation points (OP's) were established to control the separation.
Although Brčko was a focal point for tension in the late 1990s, considerable progress in multi-ethnic integration in Brčko has since occurred including integration of secondary schooling. Reconstruction efforts and the Property Law Implementation Plan have improved the situation regarding property and return.
Today, Brčko has returned to a strategic transshipment point along the Sava River. The population of Brčko has not returned to its pre-war ethnic mix of Bosniaks, Serbs, and Croats. Brčko sits at the east–west apex of Republika Srpska, the ethnic Serb portion of Bosnia & Herzegovina, and as such is critical to the RS for its economic future.
Brčko was one of the main points discussed in the Dayton Peace Accords. After several weeks of intensive negotiation, the issue of Brčko was to be decided by international arbitration. Brčko Arbitration ruled in Feb 1997 that Brčko would be managed by an ambassadorial representative from the international community.[6] The first Ambassador to Brčko was an American with support staff from the UK, Sweden, Denmark & France. Brčko Arbitration in March 1998 suggested the Brcko area could be a special district,[7] which they finally decided likewise in March 1999.[8]
Following PIC meeting on 23 May 2012, it was decided to suspend, not terminate, the mandate of Brčko International Supervisor. Brčko Arbitral Tribunal, together with the suspended Brčko Supervision, will still continue to exist.[4]
A railway station is near the city centre on the line from Vinkovci to Tuzla. However, no passenger trains operate to Brčko anymore. The closest operating railway station is in Gunja, Croatia; just on the other side of the border.
