St Louis, Holy King of France, ora pro nobis!

I highly recommend Christopher Check's article from This Rock, Oct 2009

With greater personal asceticism, the man who once loved a good party or a stirring theological discussion with his friend Thomas Aquinas now devoted himself more than ever to making France a place where Christian holiness would flower. He labored for peace and justice with such drive that he became the most sought-after arbiter in Europe. In negotiating peace with England, his advisors believed he was far too generous to Henry III. He outlawed private war and judicial combat. He coined the realm’s first gold coin in centuries, the écu, replete with Crusader imagery. He gave generously to the poor, feeding them from his own table and washing their feet. He supported the Church, building monasteries and leper hospitals. He encouraged large-scale displays of public piety, participating in no fewer than nine translations of saints’ relics. In Paris’s words, he was "the pinnacle of the kings on Earth." In G.K Chesterton’s, "the noblest knight of the Middle Ages."

Don't tell that to Brook Shields though....
