ouis IX, called St. Louis (1214-70),
king of France (1226-70), son and successor of Louis VIII. Louis's
mother, Blanche of Castile, daughter of Alfonso IX, king of
Castile, was regent during his minority and again from 1248 until
her death in 1252. During the latter years Louis was in the Holy
Land on the Seventh Crusade (see Crusades: The Later
Crusades). Louis and his forces were defeated and captured in
Egypt in 1250, and the king remained in Palestine for four years
before returning to France. In 1258 Louis signed the Treaty of
Corbeil, relinquishing to the kingdom of Aragón all French
claims to Barcelona and Roussillon, in return for which the
Aragonese renounced their claims to parts of Provence and
Languedoc. In 1259 he signed the Treaty of Paris, by which Henry
III of England was confirmed in his possession of territories in
southwestern France and Louis received the provinces of Anjou,
Normandy, Poitou, Maine, and Touraine. In 1270 Louis embarked on
another Crusade and died en route at Tunis in northern Africa. He
was succeeded by his son Philip III. Louis, an outstanding
monarch of medieval times, was canonized in 1297. His feast day
is August 25. [Microsoft Encarta 98 Encyclopedia]
