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.
Vice-Admiral of the United Kingdom
In former days, the Vice-Admiral of England (or Vice-Admiral of Great Britain following the 1707 union with Scotland) was the second most powerful position in the Royal Navy, and until 1801 was officially called the Lieutenant of the Admiralty. The office was created in 1545 by Tudor King Henry VIII. Amongst other responsibilities, the Lieutenant of the Admiralty presided over the Council of the Marine, later known as the Navy Board.
