Louise Marie-Thérèse, known as the Black Nun of Moret, was a French Benedictine nun whose dark complexion, royal pension, and association with the court of Louis XIV gave rise to enduring claims that she was a concealed member of the French royal family. Her parentage remains uncertain, but her life at Moret and her surviving portraits are well documented.
Background
Louise Marie-Thérèse was a Black or dark-skinned woman in early modern France whose origins became the subject of persistent court gossip. Later tradition identified her as the alleged daughter of Queen Marie-Thérèse of Austria and a Black man, while more recent archival research has proposed that she may instead have been an illegitimate daughter of Louis XIV and a woman connected with the theater. Neither royal-parentage theory is established as fact.
She was associated with the Benedictine convent of Villechasson-Moret at Moret-sur-Loing, a town in the royal orbit of Fontainebleau. The convent belonged to a wider network of religious houses that provided a structured setting for women's religious life, education, and retirement. Her distinctive appearance and the attention paid to her by royal and aristocratic visitors helped preserve the story surrounding her identity.
Career
Louise Marie-Thérèse spent her religious life at the Benedictine convent of Villechasson-Moret in Moret-sur-Loing, taking the name Sister Louise Marie de Sainte-Thérèse. The convent was part of the religious landscape of the French monarchy and later became known as the royal abbey of Villechasson-Moret. Its community combined monastic observance with the accommodation and education of women and girls.
Her residence near Fontainebleau placed her within reach of the royal court, which regularly visited the château and surrounding region. Accounts report visits from members of the royal family, courtiers, and other prominent figures, including Madame de Maintenon, the Grand Dauphin's family, and Voltaire. A royal pension ordered by Louis XIV further distinguished her from an ordinary nun and contributed to speculation about her parentage.
Her name appears in early modern memoirs and later historical investigations as the “Mauresse de Moret.” A portrait associated with her is preserved at the Bibliothèque Sainte-Geneviève in Paris, while another portrait is held by the municipal museum of Melun. The painter has not been established with certainty; Pierre Gobert has been proposed for one version.
Religion
Louise Marie-Thérèse was a Catholic Benedictine nun who lived under the religious name Sister Louise Marie de Sainte-Thérèse, or Sister Marie de Sainte-Thérèse. Benedictine religious life was organized around communal worship, prayer, work, and the observance of a monastic rule rooted in the tradition associated with Saint Benedict.
Her convent belonged to the Catholic religious institutions that shaped education, charitable care, and female retirement in early modern France. The Villechasson-Moret community housed religious women as well as younger residents and widows, linking monastic life with the social and educational functions commonly performed by convents during the period.
Personality
Physical Characteristics:
She was described as a Black or dark-skinned nun, a characteristic reflected in the name “Mauresse de Moret,” meaning the Black or Moorish woman of Moret.
Connections
Louise Marie-Thérèse was linked in contemporary and later accounts with the household and court of Louis XIV. Royal attention included the granting of a lifelong pension and reported visits by members of the royal family and court society. These connections generated the long-standing claim that she was related to Louis XIV or to Queen Marie-Thérèse of Austria, although the surviving evidence does not conclusively establish either parentage theory.
