At its origin, the position of Grand Chamberlain entailed oversight of the king's chamber and his wardrobe, but in October 1545, the position absorbed the duties of the position of Grand Chambrier, which was suppressed by François I, and the Grand Chamberlain became responsible for signing charters and certain royal documents, assisting at the trial of peers, and recording the oaths of homage to the Crown, among other duties.
The Grand Chamberlain also played an important role during coronation: he ceremonially admitted the clerical peers to the room of the king, and fitted the king with boots, dalmatic, and mantle for coronation.
In the protocol of the reign of Louis XIV, the Grand Chamberlain was in the second rank during ambassadorial receptions, he served the king at table, and, at the ceremony of the Levée or royal awakening, he presented the king with a shirt.
The political importance of the Grand Chamberlain stemmed from his having permanent access to the King's Chamber.
In the first half of the 16th century, the position was always held by a member of the Orléans-Longueville family, then by the Duke of Guise, and finally – until the end of the monarchy – by a member of the La Tour d'Auvergne-Bouillon family.
