The earliest people in Skopje Valley were probably the Triballi. Later the area was populated by the Paionians. Scupi was originally a Paionian settlement, but it became afterwards Dardanian town. Dardanians, who lived in present-day Kosovo, invaded the region around Skopje during the 3rd century BC. "Scupi", the ancient name for Skopje, became the capital of Dardania, which extended from Naissus to Bylazora in the second century BC. The Dardanians had remained independent after the Roman conquest of Macedon, and it seems most likely that Dardania lost independence in 28 BC.
