The Daughters of Charity were founded to nurse the poor, and their founders secured their freedom to do so by the paradoxical device of insisting that they were not nuns at all.
Not enclosed, by design
The society was founded in Paris in 1633 by Vincent de Paul and Louise de Marillac to nurse the sick poor and care for foundlings and the destitute. Because the church of the day required professed religious women to be enclosed, which would have made active service impossible, Vincent framed the Daughters not as a religious order but as a society of women taking simple annual vows, so that in law they remained laywomen free to move about the world. His famous instruction gave them for cloister the streets of the city and for grille the fear of God, turning the absence of enclosure into the whole point of the institute.
The template for active life
The Daughters spread widely and became a vast body of women engaged in nursing, teaching and the relief of the poor, recognisable for much of their history by a distinctive headdress. Their significance is larger than their own numbers, for the device Vincent used, simple vows and no enclosure, became the model on which the great active congregations of women of later centuries were built, so that the many teaching and nursing sisterhoods that followed owe their legal form to the solution he found in 1633. The Daughters of Charity thus stand at the origin of the modern active religious life for women.
