Low Down! Most Scandalous Mistresses of Yesteryear
Diane de Poitiers
Diane de Poitiers is one of the world’s most powerful mistresses. Back in the 16th century, she taught and helped raised King Francois I’s young son Henri II. After he was married, she started sleeping with him. And once he assumed the throne, she ruled the country from behind the scenes. Her reign only ended after Henri died and his real wife confiscated Catherine’s chateau and banished her to the countryside.
