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.
Royal Navy
The Acts of Union, which created the Kingdom of Great Britain in 1707, established the Royal Navy of the newly united kingdom. The Scots office of Lord High Admiral was subsumed within the office of the Admiral of Great Britain. The three vessels of the small Royal Scottish Navy were transferred to the Royal Navy.
