May this great saint and ruler pray for his namesake city and archdiocese in these troubled times. From Fisheaters:
Louis, the quintessential Christian Prince, was born in Poissy, France on 25 April 1215 to King Louis VIII and Blanche of Castile. His father died when he was just eleven years old, and he was crowned -- at Rheims, like almost all French Kings -- on the First Sunday of Advent in 1226. His very strong and pious mother acted as his regent, suppressing various revolts to secure her son's place. She acted as regent even after he reached the age of majority, and guided his career with strong Christian advice, forming his character in holiness. She would say to him, "Never forget that sin is the only great evil in the world. No mother could love her son more than I love you. But I would rather see you lying dead at my feet than know that you had offended God by one mortal sin" -- sentiments that he took to heart and would later pass on to his own successor.
