Louis XV

Louis XV was the King of France from 1715 until his death in 1774. (PROSE: A History of Humankind) Although he had a wife, he also had a mistress by the name of Jeanne-Antoinette Poisson and the pair got on well. (TV: The Girl in the Fireplace)

Most historians believed that Louis XV damaged France's power and discredited the monarchy to the point that it led to the French Revolution just fifteen years after his death; he notably reduced France's power by giving away both New France and the Austrian Netherlands.
