The feudal aristocracy would maintain great control over the king's council up until the 14th and 15th centuries. The most important positions in the court were those of the Great Officers of the Crown of France, headed by the connétable (chief military officer of the realm; established by King Philip I in 1060) and the chancellor. Other positions included the Grand Chambrier who managed the Royal Treasury along with the Grand Bouteiller (Grand Butler), before being supplanted of these functions by the Chamber of Accounts (Chambre des comptes, created by King Philip IV) and the position of Surintendant des finances (created in 1311). Certain kings were unable to reduce the importance of the feudal aristocracy (Louis X, Philip VI, John II, Charles VI), while others were more successful (Charles V, Louis XI).
