Daunians

The Daunians (Greek: Δαύνιοι, translit. Daúnioi; Latin: Daunii) were an Iapygian tribe which inhabited northern Apulia in classical antiquity. Two other Iapygian tribes, the Peucetians and the Messapians, inhabited central and southern Apulia respectively. All three tribes spoke the Messapian language, but had developed separate archaeological cultures by the seventh century BC. The Daunians lived in the eponymous region Daunia, which extended from the Ofanto river in the southeast to the Gargano peninsula in the northwest. This region is mostly coincident with the Province of Foggia today.

Towards the late Bronze Age (11th-10th centuries BC), Illyrian populations from the eastern Adriatic arrived in Apulia. The Illyrians in Italy, united with the pre-existing people and groups from the Aegean, probably from Crete, created the Iapygian civilization which consisted of three tribes: Peucetia, Messapi and the Dauni. The region was previously inhabited by Italic peoples of Southern Italy; among them are the Ausones/Oscans, Sabines, Lucani, Paeligni, Bruttii, Campanians, Aequi, Samnites and Frentani.
