Maintenon, Françoise d' Aubigné, Marquise de (1635-1719), the second wife of King Louis XIV of France. A pious woman, she satisfied the longings of Louis in his later years for a quieter, more orderly life. She secured positions for some of her favorites, but did not influence general policy. Louis's revocation in 1685 of the Edict of Nantes, which had protected Huguenots (French Protestants), has been wrongly attributed to her influence.

Françoise d'Aubigné was the descendant of a distinguished but impoverished family. Her first husband died in 1660. In 1669 she became governess of Louis's children by a mistress, the Marquise de Montespan. Eventually she displaced Madame de Montespan in the king's affections, and was made a marquise in 1678. After the death of Queen Marie Thérèse in 1683, she married the king privately, probably in 1685. She did not have the title of queen, however.

In 1686 the Marquise de Maintenon founded the convent school of Saint-Cyr for daughters of impoverished noblemen. After Louis died in 1715, the marquise came to live at Saint-Cyr. The school later became headquarters for the principal officers' training school of the French army.
