Overview
Lady of the Bedchamber is the title of a lady-in-waiting holding the official position of personal attendant on a British queen regnant or queen consort. The position is traditionally held by the wife of a peer. A lady of the bedchamber would give instructions to the women of the bedchamber on what their queen wished them to do, or may carry out those duties herself.
The equivalent title and office has historically been used in most European royal courts (Dutch: Dames du Palais; French: Dames or Dame de Palais; German: Hofstaatsdame or Palastdame; Italian: Dame di Corte; Russian: Hofdame or Statsdame; Spanish: Dueña de honor; Swedish: Statsfru).
History
In the Middle Ages, Margaret of France is noted to have had seven ladies of the bedchamber: the three married ones were called dominæ and the four unmarried ones were known as maids of honour. Their task was simply to act as the companions (see lady's companion) and personal attendants to the royal woman.
