The Vascones (singular Vasco, from Latin gens Vasconum) were a pre-Roman tribe who, on the arrival of the Romans in the 1st Century, inhabited a territory that spanned between the upper course of the Ebro river and the southern basin of the western Pyrenees, a region that coincides with present-day Navarre, western Aragon and northeastern La Rioja, in the Iberian Peninsula. The Vascones were, most likely, the ancestors of the present-day Basques to whom they left their name.
