Why was Louis IX asked to settle disputes outside France?

Louis IX was frequently asked to arbitrate disputes outside of France primarily because of his immense prestige throughout Western Christendom and his widespread reputation for fairness, wisdom, and impartiality.12

As a ruler who commanded unique levels of affection and respect, Louis IX was viewed as a just and equitable leader. This perception allowed him to serve as a trusted mediator in conflicts, such as the violent dispute between Henry III of England and his barons. His commitment to justice and his ability to act as a neutral party made him a sought-after figure for resolving external political tensions during the 13th century.12
