Juliane de Fontevrault

Juliane de Fontevrault was an illegitimate daughter of Henry I of England; her father, at her birth, was not yet king. Her mother is unknown, though some scholars have suggested the king's mistress Ansfrida (Ansfride) [1] who was the mother of Richard of Lincoln and possibly Fulk FitzRoy, two other illegitimate children of Henry.[2] Orderic's description of Juliane's mother as "a concubine" questions her identification as Ansfrida.[3] Juliane's half-siblings included Empress Matilda, William Adelin, Sybilla, Queen of Scots and Robert of Gloucester.

Juliane was married to Eustace of Breteuil, the illegitimate son of William of Breteuil, in 1103.[4] They had at least two daughters.

In February 1119, Eustace and Juliane threatened to join a rebellion against Henry I of England unless they were given the castle of Ivry.[5] To ensure Eustace's loyalty, Henry set up a hostage exchange between Eustace and Juliane's daughters (Henry's own granddaughters), and the son of Ralph Harnec, Constable of Ivry. Perhaps instigated by Amaury de Montfort, Eustace cut out the eyes of Ralph's son and sent him back to his father. Ralph furiously appealed to Henry for justice. Henry allowed Ralph to blind Eustace and Juliane's daughters, as well as cut off the tip of their noses. The incident further estranged the king and his daughter.

Enraged, Juliane journeyed to Breteuil to defend the citadel, where she found an unmotivated garrison. Informed of Juliane's actions, the king moved to Breteuil and laid siege to the citadel. Seeing no other solution, Juliane agreed to a parley with her father, but when she met with him, she unsuccessfully shot at him with a crossbow. He destroyed the drawbridge and forced her to surrender the castle, placing her in confinement. Determined to escape, she leapt from her castle tower into the freezing moat water and fled to her husband, who was at Pacy.[6] The couple lost all their property except for Pacy. Breteuil was temporarily given to William, the son of Ralph Harnec, later to Richard of Lincoln and after his death to Robert de Beaumont, 2nd Earl of Leicester, who was married to a cousin of Eustace.

Eventually, Henry pardoned Eustace and Juliane after they appealed to him on their knees. They were supported in their supplication by friends and Juliane's brother Richard. Eustace was granted three hundred silver marks each year as a compensation for Breteuil.[7] He died in 1136, and Henry died on 1 December 1135. After the death of her husband Juliane retired to the abbey of Fontevrault.[8] She lived to see early conflicts between her half-sister Maude and her cousin Stephen.
