Individual Details

Birth

Early life and marriage
Philippa was born in approximately 1073 to Count William IV of Toulouse, and his wife Emma of Mortain. She was his only surviving child, and thus, by the laws of Toulouse, his heir. In 1088, William went on a pilgrimage to Palestine, leaving his brother Raymond of Saint-Gilles as regent. Before he left, it is claimed, he also married his daughter to the King of Aragon in order to disinherit her; however, evidence suggests that Sancho was still married to his previous wife at the time of his death in 1094.)
Philippa's early life – if she was not married to Sancho Ramirez of Aragon – is something of a mystery. It is known that she did not marry William IX of Aquitaine until 1094, after the death of her father and the succession of her uncle; the circumstances in which she lived prior to her father's death, the manner of her disinheritance, and the arrangement of her marriage, are thus unknown. Those historians that argue her to have been married to Sancho Ramirez argue that her removal from Toulouse prevented her from effectively claiming her inheritance, and that with the death of Sancho, she was free to remarry based on her own choice.[3] What is certain is that, upon the death of Count William, Philippa's claims were ignored, and Raymond became count. Philippa then married William, whom she considered worthy due to his numerous merits: a handsome man fully capable of flattering a woman, he was not only one of the most prominent Dukes in Europe, able to give her the life she felt she deserved; his realm was also conveniently situated next to Toulouse, and consequently would easily be able to regain her homeland for her own – as indeed, the Duke promised to do for her. Consequently, the two swiftly married.[4] Why she was allowed by her uncle to marry such a dangerous man, or indeed if Raymond had any choice in the matter, is unknown.

Marriage

Conflict with Church and wife, 1102–1118
William, like his father and many magnates of the time, had a rocky relationship with the Church. He was excommunicated twice, the first time in 1114 for an alleged infringement of the Church's tax privileges. His response to this was to demand absolution from Peter, Bishop of Poitiers. As the bishop was at the point of pronouncing the anathema, the duke threatened him with a sword, swearing to kill him if he did not pronounce absolution. Bishop Peter, surprised, pretended to comply, but when the duke, satisfied, released him, the bishop completed reading the anathema, before calmly presenting his neck and inviting the duke to strike. According to contemporaries, William hesitated a moment before sheathing his sword and replying, "I don't love you enough to send you to paradise."
William was excommunicated a second time for "abducting" the Viscountess Dangerose (Dangerosa), the wife of his vassal Aimery I de Rochefoucauld, Viscount of Châtellerault. The lady, however, appears to have been a willing party in the matter. He installed her in the Maubergeonne tower of his castle in Poitiers (leading to her nickname La Maubergeonne), and, as related by William of Malmesbury, even painted a picture of her on his shield.
Upon returning to Poitiers from Toulouse, Philippa was enraged to discover a rival woman living in her palace. She appealed to her friends at court and to the Church; however, no noble could assist her since William was their feudal overlord, and whilst the Papal legate Giraud (who was bald) complained to William and told him to return Dangerose to her husband, William's only response was, "Curls will grow on your pate before I part with the Viscountess." Humiliated, Philippa chose in 1116 to retire to the Abbey of Fontevrault, where she was befriended, ironically, by Ermengarde of Anjou, William's first wife. While in residence she may have had direct conversations or correspondence with Countess Adela of Blois, who was in constant contact with Fontevrault from Marcigney abbey. Philippa did not survive there long, however: the abbey records state that she died on 28 November 1118.

Later career, 1118–1126
Relations between the Duke and his elder son William also became strained—although it is unlikely that he ever embarked upon a seven-year revolt in order to avenge his mother's mistreatment, as Ralph of Diceto claimed, only to be captured by his father. Other records flatly contradict such a thing. Ralph claimed that the revolt began in 1113; but at that time, the young William was only thirteen and his father's liaison with Dangerose had not yet begun. Father and son improved their relationship after the marriage of the younger William to Aenor of Châtellerault, Dangerose's daughter by her husband, in 1121.
William was readmitted to the Church around 1120, after making concessions to it. However, he was after 1118 faced with the return of his first wife, Ermengarde, who had, upon the death of Philippa, stormed down from Fontevrault to the Poitevin court, demanding to be reinstated as the Duchess of Aquitaine—presumably in an attempt to avenge the mistreated Philippa. In October 1119, she suddenly appeared at the Council of Reims being held by Pope Calixtus II and demanded that the Pope excommunicate William (again), oust Dangerose from the ducal palace, and restore herself to her rightful place. The Pope "declined to accommodate her"; however, she continued to trouble William for several years afterwards, thereby encouraging him to join the Reconquista efforts underway in Spain.
Between 1120 and 1123 William joined forces with the Kingdoms of Castile and León. Aquitanian troops fought side by side with Castilians in an effort to take Cordoba. During his sojourn in Spain, William was given a rock crystal vase by a Muslim ally that he later bequeathed to his granddaughter Eleanor. The vase probably originated in Sassanid Persia in the seventh century.
In 1122, William lost control of Toulouse, Philippa's dower land, to Alfonso Jordan, the son and heir of Raymond IV, who had taken Toulouse after the death of William IV. He did not trouble to reclaim it. He died on 10 February 1126, aged 55, after suffering a short illness.

Death

Political life
When Raymond IV of Toulouse set out on the First Crusade in the autumn of 1096, he left his son Bertrand to rule the County. However, in the Spring of 1098, William and Philippa marched into the city of Toulouse, and took control without a single life being lost. In the next year, she gave birth to her first child in the city: William the Toulousain.
In 1099, her husband went on crusade and he left her as regent in Poitou.
She was an admirer of Robert of Arbrissel and persuaded her husband to grant him land in Poitou to establish a religious community dedicated to the Virgin Mary.[6] In 1100 he founded Fontevraud Abbey there.
She was stunned in 1100 when her husband mortgaged Toulouse to her cousin Bertrand in exchange for a vast sum of money, which the Duke used to go on Crusade himself. Philippa, removed from her home, was sent to his capital of Poitiers, from where she ruled Aquitaine on behalf of her husband whilst he was absent.
After William's return, he and Philippa for a time lived contentedly with each other, producing a further five daughters, and a son, Raymond. She also ignored the Duke's sexual boasting in song and talk, instead concentrating on religion (in particular the Abbey of Fontevrault, of which she remained a keen sponsor), especially the teachings of its founder, who preached the superiority of women over men. Her obsession with a doctrine considered offensive by many men of that time, combined with William's growing dissatisfaction with her, and his teasing of her (claiming to be founding an abbey of prostitutes), led to discord in the marriage.
Toulouse had been won back by William for his wife in 1113, following the death of Bertrand in Syria in 1112: his heir being his half-brother, the 9 year old Alphonse-Jourdain, William had been unopposed. Thus, by 1114, Philippa was spending most of her time ruling there. Accordingly, she was less than pleased when, upon her return from Toulouse to Poitiers in 1114, she discovered her husband to have moved his mistress, Viscountess Dangereuse of Châtellerault, into her palace. Philippa appealed to friends and the church for assistance in ousting her husband's mistress, but to no avail – none could persuade the Duke to give up his mistress.

Later life
In 1116, a humiliated Philippa, devastated by her husband's repayment of her service to him for so many years, left the Court, taking refuge at the Abbey of Fontevrault. There she became a close friend of her husband's first wife, Ermengarde of Anjou, and the two spent much time reflecting upon the shortcomings of William. However, for all Philippa's devotion to the Abbey and its ideals, she found little peace there, both angry and resentful that her husband had cast her off in favour of a mistress. She died of unknown causes there on 28 November 1118, survived by her husband, his mistress, and Ermengarde, who would shortly attempt to avenge Philippa by attempting to have Dangereuse banished from Aquitaine.
