The Cantabri were a confederation
of eleven tribal groups living within the Spanish province of Cantabria and
partly in the provinces of Asturias and Castile-Leon, that is, in the northern
part of Spain.
The ethnonym of the Cantabras consists of the components kant- («edge», «end», «border») + -abr, -ibr («Iberians») and means «extreme Iberians», that is, «living away from the main mass of tribal groups».
