The Triballi (Ancient Greek: Τριβαλλοί, romanized: Triballoí, Latin: Triballi) were an ancient people who lived in northern Bulgaria in the region of Roman Oescus up to southeastern Serbia, possibly near the territory of the Morava Valley in the late Iron Age. The Triballi lived between Thracians to the east, Illyrians the west and Celts to the north and were influenced by them. As such in contemporary sources, they are variably described as an independent, Thracian, Illyrian or Celtic tribe. Strabo considered the Triballi as a Thracian people.[1] Most ancient sources considered the Triballi as Thracians, while some regarded them as Illyrians.[2]
As an existing people, the Triballi are mentioned for the last time by Roman historian Appian (2nd century CE). According to Appian, the Triballi were reduced in numbers through their wars against the Scordisci and fled among the Getae, north of the Danube before they went extinct as a distinct people.[3]
