Lusitanians

The Lusitanians were an Indo-European-speaking people living in the far west of the Iberian Peninsula, in present-day central Portugal and Extremadura and Castilla y Leon of Spain. It is uncertain whether the Lusitanians were Celticized Iberians or Celts, related to the Lusones. After its conquest by the Romans, the land was subsequently incorporated as a Roman province named after them (Lusitania).
