A chamberlain (Medieval Latin: cambellanus or cambrerius, with charge of treasury camerarius) is a senior royal official in charge of managing a royal household. Historically, the chamberlain superintends the arrangement of domestic affairs and was often also charged with receiving and paying out money kept in the royal chamber. The position was usually awarded as an honour to a high-ranking member of the nobility (nobleman) or the clergy, often a royal favourite. Roman emperors appointed this officer under the title of cubicularius. The Chamberlain of the Holy Roman Church enjoys very extensive powers, having the revenues of the papal household under his charge. As a sign of their dignity, chamberlains bore a key, which in the seventeenth century was often silvered, and actually fitted the door-locks of chamber rooms. Since the eighteenth century, it has turned into a merely symbolic, albeit splendid, rank-insignia of gilded bronze. In many countries there are ceremonial posts associated with the household of the sovereign.
