Eight years later, in 1236, Louis IX. attained his majority, and his mother transferred to him a power respected, feared, and encompassed by vassals always turbulent and still often aggressive, but disunited, weakened, intimidated, or discredited, and always outwitted, for a space of ten years, in their plots.
When she had secured the political position of the king her son, and as the time of his majority approached, Queen Blanche gave her attention to his domestic life also. She belonged to the number of those who aspire to play the part of Providence towards the objects of their affection, and to regulate their destiny in everything. Louis was nineteen; he was handsome, after a refined and gentle style which spoke of moral worth without telling of great physical strength; he had delicate and chiselled features, a brilliant complexion, and light hair, abundant and glossy, which, through his grandmother Isabel, he inherited from the family of the Counts of Hainault. He displayed liveliness and elegance in his tastes; he was fond of amusements, games, hunting, hounds and hawking-birds, fine clothes, magnificent furniture. A holy man, they say, even reproached the queen his mother with having winked at certain inclinations evinced by him towards irregular connections. Blanche determined to have him married; and had no difficulty in exciting in him so honorable a desire. Raymond Beranger, Count of Provence, had a daughter, his eldest, named Marguerite, “who was held,” say the chronicles, “to be the most noble, most beautiful, and best educated princess at that time in Europe. . . . By the advice of his mother and of the wisest persons in his kingdom,” Louis asked for her hand in marriage. The Count of Provence was overjoyed at the proposal; but he was somewhat anxious about the immense dowry which, it was said, he would have to give his daughter. His intimate adviser was a Provencal nobleman, named Romeo de Villeneuve, who said to him, “Count, leave it to me, and let not this great expense cause you any trouble. If you marry your eldest high, the more consideration of the alliance will get the others married better and at less cost.” Count Raymond listened to reason, and before long acknowledged that his adviser was right. He had four daughters, Marguerite, Eleanor, Sancie, and Beatrice; and when Marguerite was Queen of France, Eleanor became Queen of England, Sancie Countess of Cornwall and afterwards Queen of the Romans, and Beatrice Countess of Anjou and Provence, and ultimately Queen of Sicily. Princess Marguerite arrived in France escorted by a brilliant embassy, and the marriage was celebrated at Sens, on the 27th of May, 1234, amidst great rejoicings and abundant largess to the people. As soon as he was married and in possession of happiness at home, Louis of his own accord gave up the worldly amusements for which he had at first displayed a taste; his hunting establishment, his games, his magnificent furniture and dress, gave place to simpler pleasures and more Christian occupations. The active duties of the kingship, the fervent and scrupulous exercise of piety, the pure and impassioned joys of conjugal life, the glorious plans of a knight militant of the cross, were the only things which took up the thoughts and the time of this young king, who was modestly laboring to become a saint and a hero.
