St. Louis IX, also known as Saint Louis, was the King of France from 1226 until his death in 1270. He is remembered for his strong sense of justice, commitment to the Christian faith, and efforts to improve the welfare of his subjects. Louis led two crusades, aiming to reclaim the Holy Land, and was known for his piety and dedication to the Church. He was canonized as a saint by Pope Boniface VIII in 1297, making him one of the few monarchs to be recognized as a saint. St. Louis is the patron saint of France and is often depicted in art wearing a crown and holding a model of a church.
