Mitrovica District (Albanian: Rajoni i Mitrovicës, Serbian Cyrillic: Косовскомитровачки округ) is one of the seven districts of Kosovo. Its administrative center and the largest city is Mitrovica. The district borders on the District of Peć the south-west, District of Pristina in the south-east and east, and Serbia in the north.
The first human habitations here can be traced back to the Prehistoric period. Some Neolithic sites have been discovered in the Mitrovica District, for example in Runik, Zhitkoc and Karagac, Vallac and Fafos. This region was populated by Dardanians, an Illyrian tribe that lived in the territory of today's Kosovo.
By the end of the 1st century BC, the Romans invaded the region. At the time, one of the most important centres in the region was Municipium Dardanorum, localized in the village of Socanica, Municipality of Leposavic. Archeological sites from the Roman period were also found in the territory of Vushtrri (Vicianum), for example the ruins in the village Pestova and the Rashan Fortress.
