Lope Díaz I de Haro

Lope Díaz I de Haro (c. 1105 – 6 May 1170) was the fourth Lord of Biscay (from at least 1162). He was an important magnate in Castile during the reign of the Emperor Alfonso VII and in the kingdom of his son and grandson. Between 1147 and 1168 he is recorded as governing Old Castile on behalf of the crown.

Political career Lope was the eldest son of Diego López I and María Sánchez. On his father's death in 1124, Alfonso the Battler seized the Basque señoríos and the Rioja, annexing them to the Kingdom of Navarre. By 17 June 1125 the Battler was in the castle of Haro. Diego was succeeded by the Navarrese magnate Ladrón Íñiguez. Lope was, at the time, probably a youth of about twenty years of age. He is recorded in the Chronica Adefonsi imperatoris (I, §7) among the eleven Castilian noblemen who swore fealty Alfonso VII upon his succession in 1126.

Lope was appointed a count by 1 February 1135. By the next year (1136) he had been given the government of Nájera, which was to be the centre of his power until his death. By 1138 he was holding Álava and by 1140 Haro, the castle from which his father took the family name. In that year, however, he rebelled and was dispossessed. He seems to have been reconciled to the emperor and reinstated by 1143. In 1146 he was with the imperial court in September and again in November. There is no record of Lope's participation in the conquest of Almería (1147), but it is not unlikely.

In 1149 the emperor made Nájera the capital of a subkingdom for his eldest son, Sancho “the Desired”, but by August 1154 Lope had received de facto control of it again, although he had to wait until August 1155 to be formally re-installed as lord of Nájera. At some point Lope entrusted the government of Nájera to a certain vassal of his, Lucas López, whom he had knighted himself. After the death of Alfonso VII, Lope served Sancho as alférez between November 1157 and July 1158, although in December 1157 that post was briefly held by Pedro Fernández. on 29 November 1157 he issued a fuero to the town of Fañuela. In 1169 Lope founded a Cistercian convent at Hayuela (Fayola) in the Rioja. In 1170 it was re-founded at nearby Cañas.

In 1168 Lope gave his brother Sancho his property in the monastery of San Cipriano and in Villamezquina. A century later Lope García de Salazar called his wife Mencía, a daughter of Arias. Luis de Salazar y Castro believed that Lope had an earlier wife, name unknown, who bore him several sons, among them Lope López, who married María de Almenar. This thesis is based in part on the assumption that Lope Díaz was not the type to sire children outside of marriage. Most recently José María Canal Sánchez-Pagín has dissented from the view that Aldonza was a Castilian like her husband. She was widowed while her offspring were still young, and they rose to positions of importance in the León and Galicia, where they would have been considered foreigners if their mother was not a Leonese or Galician.

Considering Aldonza's longevity (she outlived her husband by about forty years, and was probably at least thirty years his junior), she must have been born around 1135. Jaime de Salazar y Acha, in his study of the Vela family, suggested that she was a daughter of Rodrigo Vélaz, and Canal Sánchez-Pagín originally suggested that she was his granddaughter, a daughter of Álvaro Rodríguez. In a document of 1182 recording a donation to San Prudencio de Monte Laturce that survives only in a Spanish translation by Gaspar Coronel, Aldonza calls herself a first cousin (consobrina) of Rodrigo Álvarez, son of Álvaro Rodríguez and Sancha Fernández de Traba. It is most likely, then, that she was a daughter of Sancha's brother, Gonzalo Fernández de Traba. She is known to have had close relations with Gonzalo's other children, Gómez and Urraca. She was a daughter of Gonzalo by his first wife, Elvira, a daughter of Rodrigo Vélaz.

Besides his heir, Diego II, Lope Díaz had three sons—García, Lope, and Rodrigo—and eight daughters—Aldonza, Elvira, Estefanía, María, Mencía, Sancha, Toda, and Urraca, whom Ferdinand II of León married as his final wife. Lope died on 6 May 1170, a date confirmed by the Annales compostellani. By June 1171, his widow had entered the convent at Cañas, where for over thirty years she acted as de facto abbess. She was still living in May 1207, when she made a donation to San Marcos de León.
