Gutier Menéndez (c. 865 – 934) was the most powerful Galician magnate of his time in the Kingdom of León. Related to the royal family through marriages, he acted as a powerbroker in the civil wars that followed the disputed succession of 925.
Gutier could not have been born much later than 870, since he had an adult son in 911. He was a son of Count Hermenegildo Gutiérrez and Hermesinda Gatóñez. His paternal grandparents were Gutier and Elvira, while his maternal grandparents were Count Gatón and Egilo. Gatón's sister, Nuña, was the wife of King Ordoño I, while Gutier's sister Elvira was the wife of Ordoño II.
Gutier married Ilduara Ériz, daughter of Count Ero Fernández and Adosinda. They were probably married no later than 890, judging by the ages of their children. They had three sons and two daughters:
In their testament, dated 934, Gutier and Ilduara, with the support of their relatives, divided their property roughly equally between their five children in a so-called colmellum divisionis, a division of property within a branch of a family. In the will, Gutier says that during his career he obtained wealth through "royal grants, booty in war and other means" (de munificentia regis, de preda vel de ex aliquo ganato) on top of the wealth that he had inherited.
Gutier's immense wealth is indicated by the aforementioned testament and a gift of land to his wife made on 16 August 916. He gave her lands not only in Galicia, the family's power base, but also in Portugal to the south and Asturias to the east.
During the reign of his brother-in-law, Ordoño II, king of Galicia from 910 and then of León from 914 until his death in 924, Gutier was a regular presence at the royal court. He is attested as a signatory and intervenor in numerous royal acts, and during this period his activity was not restricted to Galicia.
Ordoño II was succeeded without incident by his younger brother, Fruela II. On Fruela's death the following year (925), however, a civil war broke out between the sons of Ordoño, who were Gutier's nephews. The eldest son, Sancho Ordóñez, briefly established himself at León, but by 926 he was restricted to Galicia, while his younger brother, Alfonso IV, ruled in León. In December 927, the two kings, apparently reconciled, met to confirm the restoration of the monastery of Santa María de Loyo in the suburbs of Lugo by Gutier and Ilduara. In the royal presence, Gutier presided over the council. The situation suggests that Gutier's intervention may have reconciled the two kings, or even that he was acting as regent of the kingdom.In 927, Sancho granted Gutier the villa of Villare, which neighboured Gutier's house in Vilanova dos Infantes. Gutier's son Rudesind later built the abbey of Celanova on the land at Villare. Besides his house or palace (domus) at Vilanova, Gutier owned another at Portomarín.
Upon Sancho's death in 929, Alfonso IV took over direct rule in Galicia. On 16 August, he rewarded Gutier for his continued support with rule over six counties in Galicia: Quiroga, Santiago de Castillón, Lor, Saviñao, Louseiro and Ortigueira. The first five were all located within the Terra de Lemos not far from Lugo, while Ortigueira is on the northern coast. All are in Galicia. A document of 942, written after the death of Gutier and his brother Arias, show that they had once governed even more counties (commissa) and deaneries (decanías). The document mentions Lor and Quiroga, but also lists Bubal, Ladra, Limia, Paramo, Salnés, Sorga and Triós in Galicia, as well as Refojos de Leza further south in the county of Portugal.
Gutier witnessed many other royal acts of Alfonso IV until his overthrow by his younger brother, Ramiro II in 931. Gutier may have had a large role in Alfonso's overthrow, since he witnessed many acts of Ramiro from 931 until his death. By contrast most of the magnates who backed Alfonso against his brother were marginalized following Ramiro's victory.
