The preservation of Louise de Marillac’s relics, the process of her canonization, the miracles attributed to her, and the celebrations of her canonization are described in detail. The Daughters of Charity’s General Council began the process leading to her canonization in 1882. In 1895, her cause for beatification was introduced. Louise was beatified in 1920 and canonized in 1934. Three miraculous cures occurred before her beatification and at least two occurred between her beatification and canonization.
