The Board of Ordnance was a British government body. Established in the Tudor period, it had its headquarters in the Tower of London. Its primary responsibilities were 'to act as custodian of the lands, depots and forts required for the defence of the realm and its overseas possessions, and as the supplier of munitions and equipment to both the Army and the Navy'. The Board also maintained and directed the Artillery and Engineer corps, which it founded in the 18th century. By the 19th century, the Board of Ordnance was second in size only to HM Treasury among government departments. The Board lasted until 1855, at which point it was disbanded.

The King's Wardrobe, together with the Chamber, made up the personal part of medieval English government known as the King's household. Originally the room where the king's clothes, armour, and treasure were stored, the term was expanded to describe both its contents and the department of clerks who ran it. Early in the reign of Henry III the Wardrobe emerged out of the fragmentation of the Curia Regis to become the chief administrative and accounting department of the Household. The Wardrobe received regular block grants from the Exchequer for much of its history; in addition, however, the wardrobe treasure of gold and jewels enabled the king to make secret and rapid payments to fund his diplomatic and military operations, and for a time, in the 13th-14th centuries, it eclipsed the Exchequer as the chief spending department of central government.
