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
The office of Admiral of England (later Lord Admiral, and later Lord High Admiral) was created around 1400; there had previously been Admirals of the northern and western seas. King Henry VIII established the Council of the Marine—later to become the Navy Board—in 1546, to oversee administrative affairs of the naval service. Operational control of the Royal Navy remained the responsibility of the Lord High Admiral, who was one of the nine Great Officers of State. This management approach would continue in force in the Royal Navy until to 1832.
