The Maison du Roi (French pronunciation: [mɛzɔ̃ dy ʁwa], "The King's Household") was the name of the royal household of the King of France. It comprised the military, domestic and religious entourage of the French royal family during the Ancien Régime and Bourbon Restoration.
The exact composition and duties of its various divisions changed constantly over the Early Modern period. Officers of the Maison du Roi were directly responsible to the Grand maître de France (Chief Steward). Starting in the 16th century and then from the 17th century on, the Maison du Roi was overseen by a ministry, the Département de la Maison du Roi, directed by a secretary of state, the Secrétaire d'État à la Maison du Roi. The structure of the Maison du Roi was officially reorganized under Henry III in 1578 and 1585, and in the 17th century by Jean-Baptiste Colbert.
The military branch of the Maison du Roi was the French Army Lifeguard brigade, made up of cavalry and infantry units. Officer rank was only open to gentlemen, though some of its units were drawn from elite troops among commoners in the rest of the army. It was not ceremonial and participated in all of France's 16th- and 17th-century campaigns.
The Ecclesiastical Household of the king was headed by the Grand Almoner of France (Grand aumônier de France) (created by Francis I), most often a bishop. The king's chapel (la chapelle du roi)—which did not originally refer to a building, but to the religious entourage of the king—was in charge of the Mass and religious ceremonies (marriages, baptisms) for the sovereign and the royal family and the king's alms and public charities.
