Matilda of Anjou

Matilda of Anjou, also known as Mahaut (c. 1111 – 1154) was married in 1119 to William Adelin, son and heir apparent of Henry I of England.

Life
Matilda was the daughter of Count Fulk V of Anjou, and his first wife Ermengarde, Countess of Maine. In February 1113, Fulk V and Henry I met near Alençon where they entered into a treaty of peace which was secured by the betrothal of Henry's son William Adelin and Fulk's daughter Matilda. The young couple were married in June 1119, when Matilda was around eight years old.

On the evening of 25 November 1120, returning from Normandy to England, William Adelin chose to sail aboard the White Ship and subsequently drowned when that ship sank in the English Channel just outside Barfleur harbour. Matilda had avoided the disaster, as passage for her had been arranged aboard another ship, presumably the one that her father-in-law was traveling on. William's death left her a widow at less than ten years of age. Thus ended the treaty between England and Anjou.

On his return from Jerusalem, c. 1121–1122, Fulk V demanded the return of Matilda's dowry, comprising castles and towns in Maine, to which Henry flatly refused. After months of fruitless quarreling, Fulk considered warring with Henry once more. Finally, Fulk countered Henry by marrying his other and older daughter, Sibylla, to William Clito, the son of Robert Curthose, Henry's nephew and rival for Normandy. Fulk dowered the couple with the lordship of Maine. However, Henry I prevailed upon the pope to annul this marriage on grounds of consanguinity in 1124.

Meanwhile, after her husband's death, Matilda remained at Henry's court and was treated as one of the king's daughters. Henry maintained that she could remain as long as she wished, and intended to marry her to one of his great nobles, "heaping on her wealth and honours which would have raised her above all her family." She remained in England for several years, unmarried, but according to Orderic, wishing to see her parents and home, she returned to Anjou. After a time in Anjou, Matilda, who had remained a virgin, took the advice of Geoffrey, Bishop of Chartres, and took her vows as a nun at Fontevrault Abbey. This happened in 1128, when she was seventeen years old. She became the abbess of that abbey in 1150, and died in 1154.

In 1128, the year when she took her vows, Matilda's brother Geoffrey Plantagenet, Count of Anjou, who was 15 years old, was married to her late husband's sister, the widowed Empress Matilda, who was twenty-six. From this marriage descended the Plantagenet dynasty, which ruled England from 1154 to 1485. Indeed, every king of England beginning with Henry II descends from that marriage.
