Due to the Kosovo war, the Kosovo Albanian players left the Serbian club FK Trepča. In 1999 the Kosovo Albanians from the city decided to found their own club. The club colours are black and green. The Albanian club received the name KF Trepça, the Albanian name for FK Trepča, thus there were two clubs in the city with virtually the same name. However, the Football Federation of Kosovo is not recognized by FIFA and UEFA, thus the clubs and the Kosovo football team are also unrecognized. Thus, KF Trepça can not take on the history of the Serbian club FK Trepča. However, there is a dispute, as the Albanian club continues to claim the club history as their own.
After the Kosovo war in 1999, the city was divided into a southern part with an almost exclusively Kosovo Albanian population and a northern part with a non-Albanian or predominantly Serb population. During the war, many Serbs and non-Albanians fled to the northern part of the city or were expelled. The 2004 unrest in Kosovo reinforced the ethnic division of the city.
The home ground of the club is now the Trepča Stadium, the same stadium where the Serbian club FK Trepča played until 1999. The stadium is located in the southern part of the city, but FK Trepča is based in North Kosovska Mitrovica, in North Kosovo; it is not currently possible for them to play their home matches in their former home stadium. Currently, only Albanian teams play in Trepča Stadium, including the KF Trepça. The Trepča Stadium is now called Olympik Stadiumi Adem Jashari by the Kosovo Albanian population, after Adem Jashari, a former leader of the Albanian paramilitary rebel organisation UÇK; the non-Albanian population still uses the name Stadion Trepča. The stadium is the second largest in Kosovo with a capacity of 18,200.
