His achievements were by no means solely financial. In 1599, he was appointed grand commissioner of highways and public works, superintendent of fortifications and grand master of artillery; in 1602, governor of Nantes and of Jargeau, captain-general of the Queen's "gens d'armes" and governor of the Bastille; in 1604, he was governor of Poitou; and in 1606, made first duke of Sully and a pair de France, ranking next to princes of the blood. He declined the office of constable of France because he would not become a Roman Catholic.
