Fernando Díaz

Fernando Díaz was a Spanish nobleman and military leader in the Kingdom of León, the most powerful Asturian magnate of the period. He held the highest rank in the kingdom, that of count, from at least 24 September 1089. He was the last Count of Asturias de Oviedo and was succeeded by a castellan, a novus homo, perhaps in an ecclesiastical–royal effort to curtail the power of the Asturian aristocracy.
