Saint Genevieve was born in Nanterre and moved to Paris (then known as Lutetia) after encountering Germanus of Auxerre and Lupus of Troyes and dedicated herself to a Christian life.
In 451 she led a “prayer marathon” that was said to have saved Paris by diverting Attila’s Huns away from the city. When the Germanic king Childeric I besieged the city in 464, Genevieve acted as an intermediary between the city and its besiegers, collecting food and convincing Childeric to release his prisoners. Genevieve had frequent visions of heavenly saints and angels. She reported her visions and prophecies until her enemies conspired to drown her in a lake. Through the intervention of Germanus, their animosity was finally overcome. The Bishop of Paris appointed her to look after the welfare of the other Consecrated virgins, and by her instruction and example, she led them to a high degree of sanctity.
She is the patroness saint of Paris in the Catholic and Orthodox traditions.
