Marshal General of France

Marshal General of France, originally Marshal General of the King's Camps and Armies (French: maréchal général des camps et armées du roi), was a title signifying that its holder exercised authority over all French armies, at a time when a Marshal of France usually commanded only one army. The title was bestowed only on marshals, generally when the office of the Constable of France was vacant or, after 1626, suppressed.
