During French colonial rule in Louisiana, nuns from the French Company of Saint Ursula came to New Orleans, where they educated women and girls of European, Indian, and African descent, enslaved and free, in literacy, numeracy, and the Catholic faith. Although religious women had gained acceptance and authority in seventeenth-century France, the New World was less welcoming. Emily Clark explores the transformations required of the Ursulines as their distinctive female piety collided with slave society, Spanish colonial rule, and Protestant hostility.
