Early life Louis was the fourth child of King Louis VIII and his queen, Blanche of Castile, but, since the first three died at an early age, Louis, who was to have seven more brothers and sisters, became heir to the throne. He was raised with particular care by his parents, especially his mother. Experienced horsemen taught him riding and the fine points of hunting. Tutors taught him biblical history, geography, and ancient literature. His mother instructed him in religion herself and educated him as a sincere, unbigoted Christian. Louis was a boisterous adolescent, occasionally seized by fits of temper, which he made efforts to control. When his father succeeded Philip II Augustus in 1223, the long struggle between the Capetian dynasty and the Plantagenets of England (who still had vast holdings in France) was still not settled, but there was a temporary lull, since the English king, Henry III, was in no position to resume the war. In the south of France the Albigensian heretics, who were in revolt against both church and state, had not been brought under control. Finally, there was ferment and the threat of revolt among the great nobles, who had been kept in line by the firm hand of Philip Augustus.

In 1226 Louis VIII turned his attention to quelling the Albigensian revolt, but he unfortunately died at Montpensier on November 8, 1226, on returning from a victorious expedition. Louis IX, who was not yet 13, became king under the regency of his redoubtable mother.

Accession to the throne The queen mother’s first concern was to take Louis to Reims to be crowned. Many of the most powerful nobles refrained from participating in the ceremony, but Blanche was not a woman to be discouraged by adversity. While continuing her son’s education, she vigorously attacked the rebellious barons, particularly Hugh of Lusignan and Peter of Dreux (Pierre Mauclerc), duke of Brittany. Without support from King Henry III of England, the baronial coalition collapsed, and the Treaty of Vendôme gave Blanche a brief respite. She took advantage of it to put an end to the Albigensian revolt. Louis’s troops were sent into Languedoc, where they forced Raymond VII, count of Toulouse, to concede defeat. On April 11, 1229, the king imposed the Treaty of Paris on Raymond, in accordance with the terms of which Raymond’s daughter was to marry the king’s brother Alphonse, and, after their deaths, all of Languedoc would revert to the royal domain. As a political debut it was a magnificent success. When the students at the University of Paris revolted for a trivial reason, Louis, on his mother’s advice, closed the university and ordered the students and professors to disperse, thereby strengthening the royal authority. The problem of the Plantagenet holdings in France remained. Supported by Peter of Dreux, Henry III landed in Brittany and attempted an expedition in the west of France. Louis IX, though only 15, personally commanded the troops. He ordered the château at Angers to be rebuilt and pushed toward Nantes, where Henry was based. There was not even a battle, for, after a futile ride to Bordeaux, Henry withdrew. Truces were renewed, and Peter of Dreux submitted to Louis’s authority. When Blanche laid down the reins of government in 1234, the kingdom was temporarily at peace. Louis IX could now think about marriage. He was a splendid knight whose kindness and engaging manner made him popular. And he was a just king: although he exacted what was due him, he had no wish to wrong anyone, from the lowest peasant to the richest vassal. He often administered justice personally, either in the great hall of the Palais de la Cité, which he later endowed with a magnificent chapel, or in his Vincennes manor, where he assembled his subjects at the foot of an oak, a scene often recalled by his biographer Jean de Joinville, the seneschal of Champagne. He was also a pious king, the protector of the church and friend of those in holy orders. In 1228 he founded the noted abbey of Royaumont. Although respectful of the pope, he staunchly resisted unreasonable papal demands and protected his clergy. Blanche had selected Margaret, daughter of Raymond Berenger IV, the count of Provence, as Louis’s wife. The marriage was celebrated at Sens, May 29, 1234, and Louis showed himself to be an eager and ardent husband, which made Blanche intensely jealous of her daughter-in-law. Louis and Margaret had 11 children. After subduing Thibaut of Champagne, Louis IX had to set out again for Aquitaine. This time the rebel was Hugh of Lusignan, who had married the widowed mother of Henry III. Once again Henry descended on the Continent, this time at Royan, with a powerful force. The majority of the nobles in the west of France united with him. An almost bloodless encounter at the bridge of Taillebourg in 1242 resulted in defeat for the English, and Henry returned to London.
