Illyrian rule in the plain of Korçë with burials of their chieftains at Tumulus I in Kuç i Zi lasted until 650 BCE. During the 6th century BC, Chaonian rule was dominant over the region and their power stretched from the Ionian coast to the region of Korçë in the east. Important Chaonian settlements in the area included their capital Phoenice, the ports of Onchesmos and Chimaera (modern-day Saranda and Himara, respectively), and the port of Bouthroton (modern-day Butrint). Tumulus II in Kuç i Zi near modern Korçë is to date to the 7th century BC, and according to a historical reconstruction, it belonged to Chaonian nobles that replaced a previous Illyrian dynasty about 650 BC.
