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.
