The rivalry between two Iberian noble clans had roots in a monastic property dispute: Mummadomna, abbess of Guimarães and mother of Gonzalo Menéndez, sought to recover the monastery of Santa Comba from Guntroda, a relative of Rodrigo Velázquez. This ecclesiastical quarrel overlapped with broader Leonese succession conflicts pitting supporters of Sancho I and Ramiro III against those backing Ordoño III and later Vermudo II.
During the regency of Elvira Ramírez, the two aristocratic factions, one led by the Portuguese count Gonzalo Menéndez and the other by the Galician count Rodrigo Velázquez, met in armed battle at the hill of Aguioncha on the river Salas in the province of Ourense. Gonzalo's faction emerged victorious, resolving through force the civil conflict that had set the two noble houses against each other.
The two counts were reportedly reconciled by 968, both appearing together at the Leonese court in September of that year. Nevertheless, animosity between the families persisted; a document dated 1 October 982 still alluded to the dissension between Rodrigo Velázquez and Gonzalo Menéndez, and Gonzalo's later falling-out with Ramiro III over the Viking raids on Galicia and Portugal prolonged regional instability.
