Cantabri

The Cantabri (Greek: Καντάβροι, Kantabroi) or Ancient Cantabrians, were a pre-Roman Celtic people and large tribal federation that lived in the northern coastal region of ancient Iberia in the second half of the first millennium BC. These peoples and their territories were incorporated into the Roman Province of Hispania Tarraconensis in the year 19 BC, following the Cantabrian Wars.

Cantabri is a Latinized form of a local name, presumably meaning "Highlanders" and deriving from the reconstructed root *cant- ("mountain") in Ancient Ligurian.

Cantabria, the land of the Cantabri, originally comprised much of the highlands of the northern Spanish Atlantic coast, including the whole of modern Cantabria province, eastern Asturias, nearby mountainous regions of Castile and León, and the northern fringes of Palencia and Burgos provinces. Following the Roman conquest, this area was, however, much reduced, making up only Cantabria and eastern Asturias.

The ancestors of the Cantabri were thought by the Romans to have migrated to the Iberian Peninsula around the 4th Century BC, and were said by them to be more mixed than most peninsular Celtic peoples, their eleven or so tribes, assessed by Roman writers according to their names, were supposed to have included Gallic, Celtiberian, Indo-Aryan, Aquitanian, and Ligurian origins.
