Louis 9th, also known as Saint Louis since his canonisation in 1297, is mostly celebrated for his piety, his kindness for the poor and his rightness and is famous for doing justice under his oak in Vincennes Wood. The reign of Louis 9th was a “golden age” for France both economically and politically as Saint Louis and his court were acknowledged thorough Europe. He greatly supported the arts and built numerous religious institutions such as the Sainte Chapelle in Paris, a magnificent example of gothic art.
