Honoring a vow he had made while praying for recovery during a serious illness, Louis IX led the ill-fated Seventh Crusade and Eighth Crusade against the Muslim dynasties that ruled North Africa, Egypt and the Holy Land in the 13th century. To enforce his new legal system, Louis IX created provosts and bailiffs. He banned trials by ordeal, tried to end the scourge of private wars, and introduced the presumption of innocence to criminal procedures. He was a reformer and developed a process of French royal justice in which the king was the supreme judge to whom anyone could in theory appeal for the amendment of a judgment. His fellow European rulers esteemed him highly for his skill at arms, the power and unmatched wealth of his kingdom, but also for his reputation for fairness and moral integrity he was often asked to arbitrate their disputes. His reign is remembered as a medieval golden age in which the Kingdom of France reached an economic as well as political peak. Louis IX enjoyed immense prestige throughout Christendom and was one of the most notable European monarchs of the Middle Ages.

Louis annexed several provinces, notably parts of Aquitaine, Maine and Provence. Simultaneously, Henry III of England attempted to restore the Angevin continental possessions, but was promptly routed at the Battle of Taillebourg. During Louis' childhood, Blanche dealt with the opposition of rebellious vassals and secured Capetian success in the Albigensian Crusade, which had started 20 years earlier.Īs an adult, Louis IX faced recurring conflicts with some of his realm's most powerful nobles, such as Hugh X of Lusignan and Peter of Dreux. His mother, Blanche of Castile, ruled the kingdom as regent until he reached maturity, and then remained his valued adviser until her death.

He was crowned in Reims at the age of 12, following the death of his father Louis VIII.

Louis IX (25 April 1214 – 25 August 1270), commonly known as Saint Louis or Louis the Saint, was King of France from 1226 to 1270, and the most illustrious of the Direct Capetians.
