King Louis IX, also known as Saint Louis, was the King of France from 1226 to 1270. He is remembered for his strong sense of justice and commitment to the welfare of his people. Louis IX was deeply religious and often sought to promote peace and fairness in his kingdom. His reign is marked by efforts to improve the legal system and protect the rights of the poor. In addition to his domestic achievements, Louis IX led two crusades in the Holy Land to reclaim Jerusalem from Muslim control. His dedication to his faith and his people earned him the title of a saint after his death. Today, he is celebrated as a model of Christian leadership and compassion.
