The title Marshal General of France or more exactly "Marshal General of the King's camps and armies" (maréchal général des camps et armées du roi) was given to signify that the recipient had authority over all the French armies in the days when a Marshal governed only one army usually. This dignity was bestowed only on marshals of France, usually when the dignity of Constable of France was unavailable, or after, 1626, suppressed.
