Following the ceremony, "doctors advised against consummation" because of the relative immaturity of the bride and bridegroom. Margaret continued her studies, and Louis went on tour with Charles to loyal areas of the kingdom. Even at this time, Charles was taken aback by the intelligence and temper of his son. During this tour, Louis was named Dauphin of France by Charles, as was traditional for the eldest son of the king. The beautiful and cultured Margaret was popular at the court of France, but her marriage to Louis was not a happy one, in part because of his strained relations with her father-in-law, who was very attached to her. She died childless at the age of 20 in 1445.
