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.
Board of Admiralty
When the Navy Board was abolished in 1832 and responsibility for the civil administration of the Navy passed to the Board of Admiralty, the Board was redesigned. It now consisted of the First Lord of the Admiralty, four Naval Lords (three between 1868 and 1886), known from 1904 as Sea Lords, and a Civil Lord, with a Parliamentary and a Permanent Secretary.
