Queen of
León,
Castile, and
Galicia from 1109 until her death.
Origins El Cid was born Rodrigo Díaz circa 1043 in
Vivar, also known as Castillona de Bivar, a small town about ten kilometers (or six miles) north of
Burgos, the capital of
Castile. His father, Diego Laínez, was a
courtier,
bureaucrat, and
cavalryman who had fought in several battles. Despite the fact that El Cid's mother's family was aristocratic, in later years, the peasants would consider him one of their own. However, his relatives were not major court officials; documents show that El Cid's paternal grandfather, Laín, confirmed only five documents of
Ferdinand I's; his maternal grandfather, Rodrigo Álvarez, certified only two of
Sancho II's; and El Cid's father confirmed only one.
Service under Sancho II As a young man in 1057, El Cid fought against the Moorish stronghold of
Zaragoza, making its
emir al-Muqtadir a vassal of Sancho. In the spring of 1063, El Cid fought in the
Battle of Graus, where Ferdinand's half-brother,
Ramiro I of Aragon, was laying siege to the Moorish town of Graus, which was fought on Zaragozan lands in the valley of the
river Cinca. Al-Muqtadir, accompanied by Castilian troops including El Cid, fought against the Aragonese. The party slew Ramiro I, setting the Aragonese army on the run, and emerged victorious. One legend has said that during the conflict, El Cid killed an Aragonese knight in single combat, thereby receiving the honorific title "
Campeador". When Ferdinand died, Sancho continued to enlarge his territory, conquering both Christian strongholds and the
Moorish cities of
Zamora and
Badajoz. When Sancho learned that Alfonso was planning on overthrowing him in order to gain his territory, Sancho sent Cid to bring Alfonso back so that Sancho could speak to him.
Service under Alfonso VI Oath". In the middle of the scene,
Alfonso VI (with red cape) is swearing with his right hand on the
Bible that he did not take part in the murder of his brother
Sancho II, while El Cid stands as a witness in front of him. Sancho was assassinated in 1072, during a siege of his sister's town of Zamora. Since Sancho died unmarried and childless, all of his power passed to his brother Alfonso who, almost immediately, returned from exile in
Toledo and took his seat as king of Castile and León. He was, however, deeply suspected of having been involved in Sancho's murder. According to the 11th century epic poem
Cantar de mio Cid, the Castilian nobility led by El Cid and a dozen "oath-helpers" forced Alfonso to
swear publicly on holy relics multiple times in front of
Santa Gadea (
Saint Agatha) Church in
Burgos that he did not participate in the plot to kill his brother. This is not mentioned in the more reliable 12th century chronicle
Historia Roderici, however. El Cid's position as
armiger regis was taken away and given to his enemy, Count
García Ordóñez. In 1079, El Cid was sent by Alfonso VI to
Seville to the court of
al-Mutamid to collect the
parias owed by that
taifa to León–Castile. While he was there Granada, assisted by other Castilian knights, attacked Seville, and El Cid and his forces repulsed the Christian and Grenadine attackers at the
Battle of Cabra, in the (probably mistaken) belief that he was defending the king's tributary. During the aftermath of this battle the Muslim troops under El Cid's command would hail him as Sayyidi. Count García Ordóñez and the other Castilian leaders were taken captive and held for three days before being released. Alfonso's anger over El Cid's unsanctioned incursion into his vassal's territory would lead him to exile the knight. This is the generally accepted reason for the exile of El Cid, although several others are plausible and indeed may have been contributing factors to the exile: jealous nobles turning Alfonso against El Cid through court intrigue, and Alfonso's own personal animosity towards El Cid. The song of El Cid and subsequent tales state that Alfonso's and his court's animosity toward Rodrigo was the primary reason the expulsion of the knights from León, as well as a possible misappropriation of some of the tribute from Seville by El Cid. At first he went to
Barcelona, where
Berenguer Ramon II refused his offer of service. ==Moorish service==
