Of this marriage wrote Abbot Suger: Bohemond came to France to seek by any means he could gain the hand of the Lord Louis' sister Constance, a young lady of excellent breeding, elegant appearance and beautiful face.

The prince of Antioch was experienced and rich both in gifts and promises; he fully deserved the marriage, which was celebrated with great pomp by the bishop of Chartres in the presence of the king, the Lord Louis, and many archbishops, bishops and noblemen of the realm.The marriage was celebrated in the cathedral of Chartres between 25 March and 26 May 1106,[5] and the festivities were held at the court of Adela, who also took part in negotiations.

The groom took the opportunity to encourage the nobility to fight in the Holy Land, and also negotiated for a marriage between Bohemond's nephew Tancred, Prince of Galilee and Constance's half-sister Cecile of France.
