  Early in the first decade of the twelfth century, probably in 1104, William became archdeacon of Paris. In 1108 the reformist party received a setback when King Luis VI, King Philip's son by his "illegal marriage" ascended the throne. William resigned as archdeacon to move to the abbey of St. Victor and the Paris suburbs, where he continued to teach and remained an influential reformer. Both Hugh of St. Victor and Bernard of Clairvaux were among William's protégés from this period at St. Victor.
