Admiralty
It evolved from *Admiralty Navy War Council, (1909–1912) which in turn became the Admiralty War Staff, (1912–1917) before finally becoming the Admiralty Naval Staff in 1917. It was the former senior command, operational planning, policy and strategy department within the British Admiralty. It was established in 1917 and existed until 1964 when the department of the Admiralty was abolished, and the staff departments function continued within the Navy Department of the Ministry of Defence until 1971 when its functions became part of the new Naval Staff, Navy Department of the Ministry of Defence.
Admiralty court
England's Admiralty Courts date to at least the 1360s, during the reign of Edward III. At that time there were three such Courts, appointed by Admirals responsible for waters to the north, south and west of England. In 1483 these local courts were amalgamated into a single High Court of Admiralty, administered by the Lord High Admiral of England. The Lord High Admiral directly appointed judges to the court, and could remove them at will. This was amended from 1673, with appointments falling within the purview of the Crown, and from 1689 Judges also received an annual stipend and a degree of tenure, holding their positions subject to effective delivery of their duties rather than at the Lord High Admiral's pleasure.
