About Rodrigo of Castile
Lived 825 – 873 (aged 47–48). Rodrigo of Castile was a ruler.
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. Musa allied with Íñigo Arista of Pamplona, but the Asturians and Gascons fought against them at the Battle of Albeda. The Asturians lost not only the battle, but also control of La Rioja. Muwallad rebels were joined by Mozarabs after the Emir appointed Hashim ibn 'Abd al-Aziz as vizier. The Mozarabs of Calatrava took control of their castle and petitioned Ordoño for assistance. It was Count Gatón of El Bierzo who responded by defeating the Moorish forces at Andújar in 853. The Emir's forces continued to fight back, suppressing rebellions and seizing the Ebro valley. By appointing Rodrigo as Count of Castile, Ordoño may have been hoping that Rodrigo could achieve in La Rioja and the Ebro valley what Gatón did in Calatrava.
At this point, Rodrigo's realm (called Bardulia) was limited to a small territory bordered the Ebro River in the east, Brañosera to the west, the Cantabrian Mountains to the north and a line of fortifications, the largest of which were Merindad de Losa and Valle de Tobalina, to the south. The earliest documentation of Rodrigo as count was the foundation charter of San Martín de Ferrand (in Herrán, Burgos) dating from 852, although this is now believed to be a forgery. There are a number of charters under his name claiming to be from 853–862, but the earliest one that can be dated with certainty is from 862:
Reconquistador From the very beginning of his reign, Rodrigo took an active part in the Reconquista. In the year 854, Castillan soldiers participated in the capture of Haro, and a little later captured Muslim fortifications in Cerezo de Río Tirón, Carrias and Grañón. Meanwhile, Ordoño I and Rodrigo conducted extensive construction of new fortresses on the Muslim border, among which were Frias and Lantarón. In it, the combined Asturian-Pamplonan army commanded by Ordoño and García Íñiguez of Pamplona defeated the army of Musa ibn Musa, who owned vast territories bordering Asturias and Pamplona. The number of Muslim casualties, according to various sources, ranged from 10,000 to 20,000 soldiers. Musa himself was seriously wounded and until his death in 862 did not campaign against the Christians. Albelda, one of the main Moorish fortifications in the Muslim-Christian borderlands, was destroyed.
Peña Amaya, ancient capital of the duchy of Cantábria. When Musa died, his son Lubb (who had inherited Toledo) swore fealty to Ordoño. This allowed the Christians to expand to the south peacefully, both by repopulating the area known as the Desert of the Duero and by being welcomed by Christian-majority cities formerly under Muslim rule. The repopulation efforts were mostly led by the clergy, but Rodrigo also took part in Ordoño's Repoblación, repopulating Amaya in 860. Amaya was known as the "patrician city" because at one time it had been the capital of eight of the provinces of the Visigothic Kingdom of Toledo which had been conquered in 711-712 by Tariq ibn Ziyad. It had been left empty since Tariq's conquest.thumb
A significant part of Rodrigo's re-settlers were Mozarabs who fled to Asturias from persecution in the Emirate of Cordoba. Having settled Amaya, Rodrigo prepared for the expansion of Castile to the south. Rodrigo constructed fortresses along the new border. These became the basis for the modern municipalities of Úrbel del Castillo, Castil de Peones, Moradillo de Senado (in Burgos) and Villafranca Montes de Oca. At the same time, Ordoño ravaged Coria. and Cerezo de Rio Tiron, while the Alavians took possession of Cellorigo.
Internal Conflicts King Ordoño, was succeeded on May 27, 866 by his eldest son Alfonso III of Asturias who at that time was about 18 years old. At the time Alfonso was in Santiago de Compostela. Almost immediately, a rebellion broke out against him, led by Count Fruela Bermudez of Lugo. Fruela captured the Asturian capital of Oviedo and was made king. Alfonso was overthrown and took refuge in Castile. Count Rodrigo quickly raised an army and entered the Kingdom of Asturias to support the young monarch, who was crowned in Oviedo on Christmas Day. Rodrigo was present for the coronation and, like every other lord of the realm, took an oath of loyalty. or 5 November of the same year, and was succeeded by his son Diego Rodríguez. This happened with the approval of the king, and is the first example of a count inheriting his possessions in Asturias.
Legacy Rodrigo's role as probable founding count of Castile has led to an amplification of his actual activities, with forged charters pushing his rule in the county a decade earlier than it can reliably be traced. This process has also led to the duplication of himself and his son, in the form of an invention of earlier counts Rodrigo (supposed brother of Aurelius and Vermudo I) and Diego. He is remembered as a shield of Christendom, who took advantage of the weakness of his enemies and reorganised his own defences. He formed the County of Castile and then expanded it, adding a number of fortresses and the city of Amaya. He also secured rights for his county which were passed on to his son Diego and his successors, ensuring the importance of Castile in future generations.
