Overview
Ruderick (Latin: Rudericus; died on 4 October – 5 November 873), better known by his Spanish name Rodrigo, was an influential noble of the Kingdom of Asturias, and was probably the first Count of Castile (850/862–873) and Álava (867/868–870). He was an active participant in the Reconquista and a faithful vassal of Ordoño I and Alfonso the Great, kings of Asturias. By conquering land from the Moors, Rodrigo began the southern expansion of the County of Castile.
Origins
Rodrigo's parentage is not historically documented. Some Iberian Muslim writers refer to a brother or brother-in-law of Ordoño I active in Castile, while others assign the same role to a Ruderick without stating a relationship, and the references have been interpreted as referring to the same man. It seems that due to the missions entrusted to him, it is probable that he was close to the royal house. Fernández de Béthencourt placed him as brother of Ordoño I and son of Ramiro I of Asturias by his second wife, Paterna. Were this true, Rodrigo would have become Count of Castile and when still a child, since Ramiro and Paterna did not marry until around 842, making a number of historians consider this unlikely. Barrau-Dihago dismissed this interpretation due to the lack of support from primary sources. An alternative reconstruction would make Rodrigo the brother of Ordoño's wife Munia.
Count of Castile
Rodrigo was created governor of the eastern march (marca oriental) of the realm, the territory called al-Qila by the Arabs, which later became the county of Castile. The area is believed to have earned this name due to the fact that there are few naturally occurring defensible positions, which lead to the creation of castles, or castillos, to defend the region. Rodrigo is traditionally believed to have been made governor in 850, possibly upon Ordoño's assumption of the crown. The primary reason for the introduction of these comital powers was to improve how the eastern regions of Asturias were managed, as they were crucial outposts against the Moors. It was also important for Ordoño to leave these possessions under the control of his relatives and preferably members of his immediate family. In return for their loyalty, these new counts were granted great amounts of freedom.
These appointments also coincided with a rebellion against the Emir led by Musa ibn Musa al-Qasawi of the Muwallad Banu Qasi tribe.
