Mother Saint Michel brought a personal devotion to Mary under this title to the Ursuline convent in New Orleans when she arrived in 1810. The seemingly miraculous victory of the Americans over the British at the Battle of New Orleans in 1815 confirmed the spreading devotion, and Pope Pius IX granted formal approval of the Feast of Our Lady of Prompt Succor in 1851. The statue that inspired Mother Saint Michel's new title was solemnly crowned in 1894, becoming the patroness of Louisiana. It was later enshrined in the chapel on the grounds of the Ursuline convent and academy.
