Mountainous district, ancient Spain.
Located in northeastern Spain between the Ebro and Tagus rivers, it had long been inhabited before it was occupied in the 3d century BC by tribes of mixed Iberian and Celtic stock. The Celtiberians first submitted to Rome in the early 2nd century BC but were not completely dominated until 133 BC. Excavated horse bits, daggers, and shield fittings attest to their warlike nature.
