Prijepolje was established as a settlement in 1234, the same year the Mileševa Monastery was built. Prior to its establishment as a settlement, the area was occupied as far back as the stone age. First settled by Illyrians, who migrated to the area after being forced out of the northern plains, they retreated to the more defensible and less accessible mountainous regions. Later arrivals were the Celts, with whom the Illyrians intermarried. With the arrival by the Romans, the Illyrians were again forced to flee, and after the Romans, the Slavs settled in the area, intermixing with some of the earlier Illyrians. The Goths, Huns, Gepids, Langobards and Avars also passed through this area. The most interesting archaeological site in the territory is the Roman necropolis near the modern settlement of Kolovrat where pieces of ancient glass, silver, ceramics, and gold have been unearthed.
