Diane De Poitiers Mistress of Henri II, King Of France: Diane de Poitiers, born on January 9, 1500, was Countess of SaintVallier and Duchess of Valentinois. She was the mistress of Henry II, King of France for over twenty years. Historical sources about De Poitiers are few. History has forged an image of her as a woman of character, eager for power, full of ambition, and a great patron of the arts. But in fact, none of this has been historically proven.
