Patron of Tertiaries
St. Louis, King of France, patron of Tertiaries, was the ninth of his name. He was born at Poissy, France, in 1214. His father was Louis VIII, and his mother was Blanche, daughter of Alfonso VIII of Castille, surnamed the Conqueror. At the age of twelve he lost his father, and his mother became regent of the kingdom. From his tenderest infancy she had inspired him with a love for holy things.
In 1234, he married Margaret, the virtuous daughter of Raymond Berenger, Count of Provence, and two years later he took the reigns of government into his own hands. In 1238, he headed a crusade, in which he fell a prisoner among the Mohammedans, but a truce was concluded and he was set free and he returned to France. In 1267, he again set out for the East at the head of a crusade but he never again beheld his native land. In 1270, he was stricken by the pestilence at the siege of Tunis, and after receiving the Last Sacraments, he died. His feast day is August 25th.
Louis was born on 25 April 1214 at Poissy, near Paris, the son of Prince Louis the Lion and Blanche of Castile, and baptised in La Collégiale Notre-Dame church.His grandfather was King Philip II of France. He was 9 years old when his grandfather died and his father ascended as Louis VIII. A member of the House of Capet, Louis was twelve years old when his father died on 8 November 1226. He was crowned king within the month at Reims cathedral. Because of Louis's youth, his mother ruled France as regent during his minority.
His younger brother Charles I of Sicily (1227–85) was created count of Anjou, thus founding the second Angevin dynasty.
No date is given for the beginning of Louis's personal rule. His contemporaries viewed his reign as co-rule between the king and his mother, though historians generally view the year 1234 as the year in which Louis began ruling personally, with his mother assuming a more advisory role. She continued as an important counselor to the king until her death in 1252.
On 27 May 1234, Louis married Margaret of Provence (1221 – 21 December 1295), whose sister Eleanor was the wife of Henry III of England
