Madame de Montespan

Françoise-Athénaïs de Rochechouart de Mortemart, Marquise of Montespan, commonly known as Madame de Montespan, was a French noblewoman and the most celebrated royal mistress of King Louis XIV. During their romantic relationship, which lasted from the late 1660s to the late 1670s, she was sometimes referred to by contemporaries as the "true Queen of France" due to the pervasiveness of her influence at court.
