The Master of the Horse in England is an important official of the sovereign's household.
The master of the horse is the third dignitary of the court, and was always a member of the ministry (before 1782 the office was of cabinet rank), a peer and a privy councillor.
The original Master of the Horse ( Latin : Magister Equitum) in the Roman Republic was an office appointed and dismissed by the Roman Dictator, and ceasing to exist once the Dictator left office.
The Master of the Horse held Praetorian imperium, was attended by six lictors, and was charged with assisting the Dictator in managing the State.
All matters connected with the horses and hounds of the sovereign, as well as the stables and coachhouses, the stud, mews and kennels, are within his jurisdiction.
