Louis XV
King Louis XV of France was the lover of Jeanne-Antoinette Poisson in her later life. Reinette got on well, as his official mistress, with the king's wife. He was dubious about the Tenth Doctor until the Doctor saved him from the Clockwork Droids in 1758. (TV: The Girl in the Fireplace)
In 1747, he provided the statue Mannikin Pis with its first clothes. (PROSE: Escape Velocity)
In 1758, Louis XV expelled Voltaire from the French court. (AUDIO: Masquerade)
When the Tenth Doctor arrived in France in 1764, it was in time to see Reinette's hearse leaving Versailles for her grave. The King gave the Doctor a letter from his mistress. (TV: The Girl in the Fireplace)
