Matilda appears to have been unimpressed by the prospect of marrying Geoffrey of Anjou. She felt that marrying the son of a count diminished her imperial status and was probably also unhappy about marrying someone so much younger than she was; Matilda was 25 and Geoffrey was 13. Hildebert, the Archbishop of Tours, eventually intervened to persuade her to go along with the engagement. Matilda finally agreed, and she travelled to Rouen in May 1127 with Robert of Gloucester and Brian Fitz Count where she was formally betrothed to Geoffrey. Over the course of the next year, Fulk decided to depart for Jerusalem, where he hoped to become king, leaving his possessions to Geoffrey. Henry knighted his future son-in-law, and Matilda and Geoffrey were married a week later on 17 June 1128 in Le Mans by the bishops of Le Mans and Séez. Fulk finally left Anjou for Jerusalem in 1129, declaring Geoffrey the count of Anjou and Maine.
