Brčko was a geographic point of contention in 1996 when the U.S.-led Implementation Forces (IFOR) built McGovern Base on the outskirts of the city. Camp McGovern as it is known was built in the ZOS for the purpose of establishing peacekeeping operations, specifically between Muslims in Gornji Rahić and Serbs in Brčko. Tensions were mainly over disputed properties within the ZOS which both sides claimed were theirs. In some cases, Muslims rebuilt their reclaimed properties during the day, and then would find their newly-repaired homes destroyed overnight after they left the ZOS to return to Gornji Rahić. The explosions were typically in threes, which was a symbolic gesture from the Serbs known as Trojka.


Demographics
