Françoise-Athénaïs de Rochechouart de Mortemart, marquise de Montespan (October 5, 1641 – May 27, 1707), better known as Madame de Montespan, was one of the most famous mistresses of Louis XIV of France
Born into one of the oldest noble families in France, the House of Rochechouart, Madame de Montespan was called by some the True Queen of France during her romantic relationship with Louis XIV due to the pervasiveness of her influence at court during that time.
Her so-called reign lasted from around 1667, when she first danced with Louis XIV at a ball hosted by the king's younger brother, Monsieur, at the Louvre, until her alleged involvement in the notorious Affaire des Poisons in the late 1670s to 1680's. She is an ancestor of many royal houses in Europe such as Spain, Italy, Bulgaria and Portugal.
