Information: - The Albigensian Crusade or Cathar Crusade (12091229) was a 20-year military campaign initiated by Pope Innocent III to eliminate Catharism in Languedoc, in the south of France. The Crusade was prosecuted primarily by the French crown and promptly took on a political flavour, resulting in not only a significant reduction in the number of practising Cathars, but also a realignment of the County of Toulouse, bringing it into the sphere of the French crown and diminishing the distinct regional culture and high level of influence of the Counts of Barcelona. - Louis IX ( 25 April 1214 -- 25 August 1270 ) , commonly known as Saint Louis , was a Capetian King of France who reigned from 1226 until his death . Louis was crowned in Reims at the age of 12 , following the death of his father Louis VIII the Lion , although his mother , Blanche of Castile , ruled the kingdom until he reached maturity . During Louis 's childhood , Blanche dealt with the opposition of rebellious vassals and put an end to the Albigensian crusade which had started 20 years earlier . As an adult , Louis IX faced recurring conflicts with some of the most powerful nobles , such as Hugh X of Lusignan and Peter of Dreux . Simultaneously , Henry III of England tried to restore his continental possessions , but was defeated at the battle of Taillebourg . His reign saw the annexation of several provinces , notably Normandy , Maine and Provence . Louis IX was a reformer and developed French royal justice , in which the king is the supreme judge to whom anyone is able to appeal to seek the amendment of a judgment . He banned trials by ordeal , tried to prevent the private wars that were plaguing the country and introduced the presumption of innocence in criminal procedure . To enforce the correct application of this new legal system , Louis IX created provosts and bailiffs . According to his vow made after a serious illness , and confirmed after a miraculous cure , Louis IX took an active part in the Seventh and Eighth Crusade in which he died from dysentery . He was succeeded by his son Philip III. Louis 's actions were inspired by Christian values and Catholic devotion . He decided to punish blasphemy , gambling , interest - bearing loans and prostitution , and bought presumed relics of Christ for which he built the Sainte - Chapelle . He also expanded the scope of the Inquisition and ordered the burning of Talmuds . He is the only canonized king of France , and there are consequently many places named after him . - Catharism (from the Greek: , "katharoi", "the pure [ones]") was a Christian dualist or Gnostic revival movement that thrived in some areas of Southern Europe, particularly northern Italy and southern France, between the 12th and 14th centuries. Cathar beliefs varied between communities, because Catharism was initially taught by ascetic priests who had set few guidelines. The Catholic Church denounced its practices including the "Consolamentum" ritual, by which Cathar individuals were baptized and raised to the status of 'perfect'.
