From Wikipedia - Alfonso VI of León and Castile :

Alfonso VI (before June 1040 - June 29 /July 1 , 1109 ), nicknamed the Brave (El Bravo) or the Valiant, was King of León from 1065 to 1109 and King of Castile from 1072 following the death of his brother Sancho II . In 1077 he proclaimed himself "Emperor of all Spain ". Much romance has gathered around his name.

Early life
As the second and favorite son of King Ferdinand I of León and Princess Sancha of León , Alfonso was allotted León, while Castile was given to his eldest brother Sancho , and Galicia to his youngest brother García . Sancho was assassinated in 1072. García was dethroned and imprisoned for life the following year.

In the cantar de gesta The Lay of the Cid , he plays the part attributed by medieval poets to the greatest kings, and to Charlemagne himself. He is alternately the oppressor and the victim of heroic and self-willed nobles - the idealized types of the patrons for whom the jongleurs and troubadours sang. He is the hero of a cantar de gesta which, like all but a very few of the early Spanish songs, like the cantar of Bernardo del Carpio and the Infantes of Lara , exists now only in the fragments incorporated in the chronicle of Alfonso the Wise or in ballad form.

His flight from the monastery of Sahagún (Safagún in Leonese language ), where his brother Sancho endeavoured to imprison him, his chivalrous friendship for his host Almamun of Toledo , caballero aunque moro, "a knight although a Moor ", the passionate loyalty of his vassal, Pero (Pedro) Ansúrez, and his brotherly love for his sister Urraca of Zamora , may owe something to the poet who took him as a hero.

They are the answer to the poet of the nobles who represented the king as having submitted to taking a degrading oath at the hands of Rodrigo Díaz de Vivar (El Cid ) to deny intervention in his brother's death in the church of Santa Gadea at Burgos , and as having then persecuted the brave man who defied him.

Marriages and children
Alfonso married at least five times and had two mistresses and a fiancée:

In 1067, two brothers from Iberia are said to have competed for the hand of Agatha , one of the daughters of William I of England and Matilda of Flanders and formerly fiancee of Harold Godwinson . Alfonso proved successful, and was betrothed to Agatha. A nun at the time, Agatha is said to have prayed for death rather than being forced to marry Alphonso, and she died before the marriage could take place.

In 1069, Alfonso married Agnes of Aquitaine , daughter of William VIII of Aquitaine and his second wife Mateoda. They last appear together in May 1077, and then Alfonso appears alone. This suggests that she had died, although Orderic Vitalis reports that in 1109 Alfonso's 'relict' Agnes remarried to Elias I of Maine , leading some to speculate that Alfonso and Agnes had divorced due to consanguinity . It seems more likely that Orderic gave the wrong name to Alfonso's widow, Beatrice. Agnes and Alfonso had no children.

Apparently between his first and second marriages he formed a liaison with Jimena Muñoz , a "most noble" (nobilissima) concubine "derived from royalty" (real generacion). She appears to have been put aside, given land in Ulver, at the time of Alfonso's remarriage. By her Alfonso had two illegitimate daughters, Elvira and Teresa .

His second wife, who he married by May 1080, was Constance of Burgundy , daughter of Robert I, Duke of Burgundy . This marriage initially faced papal opposition, apparently due to her kinship with Agnes. Her reign as queen brought significant Cluniac influences into the kingdom. She died in September or October, 1093, the mother of Alfonso's eldest legitimate daughter Urraca , and of five other children who died in infancy.

Either late in Constance's reign or shortly after her death, Alfonso formed a liaison with a second mistress, Zaida of Seville , said by Iberian Muslim sources to be daughter-in-law of Al Mutamid , the Muslim King of Seville. She fled the fall of Seville for Alfonso's kingdom in 1091, and soon became his lover, having by him Alfonso's only son, Sancho , who, though illegitimate was apparently not born of an adulterous relationship, and hence born after the death of Constance. He would be named his father's heir. Several modern sources have suggested that Zaida, baptised under the name of Isabel, is identical with Alfonso's later wife, queen Isabel (or that she was a second queen Isabel who he married in succession to the first). Zaida/Isabel died in childbirth, but the date is unknown, and it is unclear whether the child being delivered was Sancho, an additional illegitimate child, otherwise unknown, or legitimate daughter Elvira (if Zaida was identical to Queen Isabel).

By April 1095, Alfonso married Bertha. Chroniclers report her as being from Tuscany , Lombardy , or alternatively, say she was French. Several theories have been put forward regarding her origin. Based on political considerations, proposals make her daughter of William I, Count of Burgundy or of Amadeus II of Savoy . She had no children and died in late 1099 (Alfonso first appears without her in mid-January 1100).

Within months, by May 1100, Alfonso again remarried, to Isabel, having by her two daughters, Sancha, (wife of Rodrigo González de Lara ), and Elvira , (who married Roger II of Sicily ). A non-contemporary tomb inscription says she was daughter of a "king Louis of France ", but this is chronologically impossible. It has been speculated that she was of Burgundian origin, but others conclude that Alfonso married his former mistress, Zaida, who had been baptized as Isabel. (In a novel twist, Reilly suggested that there were two successive queens named Isabel: first the French (Burgundian) Isabel, mother of Sancha and Elvira, with Alfonso only later marrying his mistress Zaida (Isabel), after the death of or divorce from the first Isabel.) Alfonso was again widowed in mid-1107.

By May 1108, Alfonso married his last wife, Beatrice . She, as widow of Alfonso, is said to have returned home to France, but nothing else is known of her origin unless she is the woman Orderic named as "Agnes, daughter of William, Duke of Poitou", who as relict of Alfonso, (Agnetem, filiam Guillelmi, Pictavorum ducis, relictam Hildefonsi senioris, Galliciae regis), remarried to Elias of Maine. If this is the case, she is likely daughter of William IX of Aquitaine and niece of Alfonso's first wife. Beatrice had no children by Alfonso.

Alfonso's designated successor, his son Sancho, was slain after being routed at the Battle of Uclés in 1108, making Alfonso's eldest legitimate daughter, the widowed Urraca as his heir. In order to strengthen her position as his successor, Alfonso began negotiations for her to marry her second cousin, Alfonso I of Aragon and Navarre , but died before the marriage could take place, Urraca succeeding.
