 The nuns established a convent and founded what is the oldest school for girls in the territory of the modern-day U.S., Ursuline Academy, which educated the children of European colonists, Native Americans, and those of the local Creole people, slave or free.Spanish sisters came to assist the growing school in 1763 after Louisiana fell under Spanish control.In 1800 the territory came back under French possession, and in 1803, most of the sisters, fearing the anti-clerical sentiment of the French Revolution, fled to Havana, Cuba.
