Maximilien de Bèthune, duc de Sully (1560 - 1641) was a soldier, minister, Huguenot and superintendent of finances to Henry IV of France until that king was assassinated. His memoirs, written in the second person, are valuable as historical documents and as an autobiography - despite the fact that they contain many fictions, such as a mission undertaken by Sully to Queen Elizabeth I in 1601.
