Louis Antoine de Pardaillan was a French nobleman, marquis of Antin, Gondrin and Montespan, and first Duke of Antin.

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 as the "true Queen of France" due to the pervasiveness of her influence at court.
