Alfonso Enríquez, Count of Gijón and Noreña

Alfonso Enríquez (Gijón, 1355 – Marans or Portugal, c. 1400), Count of Noreña and of Gijón and lord of several places, was the eldest son of King Henry II of Castile and Elvira Íñiguez born before the king's marriage. As one of the most powerful feudal lords in Asturias, where he owned many properties, he attempted to declare the independence of this region from his brother King John I and then from his nephew, King Henry III of Castile. He and his Portuguese wife, Isabel of Portugal, a natural daughter of King Ferdinand I, are the ancestors of the Noronha lineage in Portugal.

Alfonso was raised close to his father during his youth. A year before his reign as king of Castile and León, Henry II gave Alfonso the lordship of Noreña and as such he appears confirming a charter in November 1368. He was knighted by his father in Santiago de Compostela in the spring of 1372 and it was probably at that time that he received the titles of Count of Noreña and of Gijón. He also received the properties that his father had inherited from his godfather and tutor, Rodrigo Álvarez, in León. In Asturias, these included the strategic counties of Noreña and Gijón plus Ribadesella, Villaviciosa, Nava, Laviana, Cudillero, Luarca, and Pravia. In León, he also owned the two Babias and Argüellos, both territories on the border with Asturias thanks to which he was able to move from one region to another without having to abandon his domains.
