    History Guillaume was born in Toulouse in 1099, the son of Guillaume VII-IX de Poitou, duke of Aquitaine, and his second wife Philippa Mathilde de Toulouse, during the brief period when his parents ruled the capital. His birth is recorded in the Chronicle of Saint-Maixent for the year 1099: _Wilhelmo comiti natus est filius, equivoce Guillelmus vocatus_ (\'a son was born to Count Guillaume, named Guillaume like himself\'). Later that same year, much to Philippa\'s anger, Guillaume VII-IX mortgaged Toulouse to her cousin Bertrand of Toulouse, and then left on Crusade. Philippa and her infant son were left in Poitiers. Long after Guillaume\'s return he took up with Maubergeon/Dangerose de L\'Isle-Bouchard, the wife of one of his vassals Ayméric I, vicomte de Châtellerault, and set Philippa aside.

    In 1121 the younger Guillaume married Aénor de Châtellerault, daughter of his father\'s mistress Dangerose. Guillaume and Aénor had three children, of whom their two daughters, Eleonor the future duchess of Aquitaine, and Petronella/Alix would have progeny.

    In 1126 Guillaume succeeded his father as Guillaume X, duke of Aquitiane and Guillaume VIII, comte de Poitou. Like his father before him, Guillaume was a patron of troubadours, music and literature. He was an educated man and strove to give his two daughters an excellent education, in a time when Europe\'s rulers were hardly literate. When Eleanor succeeded him as duchess, she would continue Guillaume\'s tradition and transform the Aquitanian court into Europe\'s centre of knowledge.

    Aénor died in 1130, and in 1136 Guillaume married Emma de Limoges, widow of Bardon de Cognac and daughter of Ademar III \'le Barbu\', comte de Limoges and Marie des Cars. They had no children. Guillaume was both a lover of the arts and a warrior. He became involved in conflicts with Normandy (which he raided in 1136, in alliance with Geoffrey \'le Bel\' of Anjou who claimed it in his wife\'s name) and France.

    Even inside his borders, Guillaume faced an alliance of the Lusignans and the Parthenays against him, an issue resolved with the total destruction of his enemies. In international politics, Guillaume initially supported Antipope Anacletus II in the schism of 1130, and opposed Pope Innocent II, against the will of his own bishops. In 1143 Saint Bernard of Clairvaux convinced Guillaume to drop his support to Anacletus and join Innocent.

    In 1137 Guillaume joined the pilgrimage to Santiago de Compostela, but died of suspected food poisoning during the trip. On his deathbed he expressed his wish to see King Louis VI of France as protector of his fifteen-year-old daughter Eleanor, and to find her a suitable husband. Louis VI naturally accepted this guardianship and married the heiress of Aquitaine to his own son Louis VII.  [1
