At this time Louis was already a widower, having been married at the age of thirteen to Margaret of Scotland, who led a mournful existence at the French court, where she felt herself a desolate alien. Her death at the age of twenty was possibly due to slander. "Fie upon life," she said on her deathbed, when urged to rouse herself to resist the languor into which she was sinking. "Talk to me no more of it." Her husband cared less for her life than did Margaret herself. He took no interest in the inquiry set on foot to ascertain the truth of the charges against the princess, and was more than ready to turn to a new alliance. At the date of his widowerhood he was in Dauphiné and his own choice for a wife was Charlotte, daughter of the Duke of Savoy. After negotiations in his own behalf he informed his father of his matrimonial project. It did not meet the views of Charles VII., who ordered his son to abandon the idea immediately. A messenger was despatched post haste to Chambéry to stop the dauphin's nuptials.[11] The duke evaded an interview and the envoy was forced to deliver his letter to the chancellor of Savoy. On the morrow of his arrival, he was taken to church, where the wedding ceremony was performed (March 10, 1451), but his seat was in such a remote place that he could barely catch a glimpse of the bridal procession, though he saw that Louis was clad in crimson velvet trimmed with ermine. Two days later the envoy carried a pleasant letter to the king, expressing regrets on the part of the Duke of Savoy that the alliance was made before the paternal prohibition arrived. Nine years were spent by Louis in Dauphiné. He introduced many administrative and judicial reforms, excellent in themselves but not popular. There were various protests and when he dared to impose taxes without the consent of the Estates, an appeal was made to the king begging him to check his son in his illegal assumptions. Charles summoned his son to his presence. Instead of obeying this order in person, Louis sent envoys who were dismissed by his father with a curt response: "Let my son return to his duty and he shall be treated as a son. As to his fears, security to his person is pledged by my word, which my foes have never refused to accept."[12] Louis showed himself less compliant than his father's foes. As Charles approached Dauphiné, and made his preparations to enforce obedience, Louis appealed to the mediation of the pope, of the Duke of Burgundy, and of the King of Castile, beside sending offerings to all the chief shrines in Christendom, imploring aid against parental wrath. Then his thoughts took a less peaceful turn. He called the nobles of his principality to arms and bade the fortified towns prepare for siege, while he loftily declared that he would not trouble his father to seek him. He would meet him at Lyons.
