He had been inducted into the Order of the Holy Spirit in 1585 by Henry III. Henry IV made him "Grand mâitre" of the royal household and governor of the province of Brittany in 1589. In 1602 he was made governor of the Dauphiné, and of Normandy in 1610, in which year he was also present at the coronation of Louis XIII. After Henry's death later that year, Soissons opposed the policies of his widow, the queen regent Marie de' Medici. In 1612 Samuel de Champlain convinced Charles to obtain the office of Lieutenant-General from King Louis XIII, which he did.
