a French conspirator and the killer of king Henry III. He was born at Serbonnes, in today's Yonne département, in Burgundy, and became a Dominican lay brother. During the French Wars of Religion, Clément became fanatically religious and an ardent partisan of the Catholic League. Viewing Protestantism as heresy, he talked of exterminating the Huguenots and formed a plan to assassinate Henry III. His project was encouraged by some of the heads of the League, in particular Catherine de Guise, the Duchess Montpensier.
