He worked successfully from the regime of Louis XVI, through the French Revolution and then under Napoleon I, Louis XVIII, Charles X, and Louis-Philippe. Some regard him as one of the most versatile, skilled and influential diplomats in European history, and some believe that he was a traitor, betraying in turn, the Ancien Régime, the French Revolution, Napoleon, and the Restoration. He is also notorious for leaving the Catholic Church after ordination to the priesthood and consecration to the episcopacy.
