[2] 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.

[3] The city is on the north, riparian border of Bosnia, across the Sava River from the village of Gunja in Croatia.

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 ZOS was one kilometer wide of no man's land, where special permission was required for Serbian or Bosnian forces to enter.

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.

The city is home to an economics school of the University of East Sarajevo and a local theatre festival.
