Born in 1225, Saint Isabel was the daughter of Louis VIII of France. Devoutly religious, she founded the Monastery of the Order of Poor Ladies of Saint Clare, a Franciscan Order whose Rule was approved by Pope Alexander IV in 1259. Under the Rule, Isabel was able to live uncloistered at her home in Longchamp and to continue her lifelong work helping the sick and the poor. Isabel died at her home in 1270.
