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.
Irish Coast Guard
The British Water Guard (formed 1809) and (Preventive) Coast Guard (formed 1822) extended to Ireland as part of the United Kingdom of Great Britain and Ireland. During this period the Coast Guard played revenue protection and coastal defence roles, as well as forming part of the Royal Naval Reserve. In the 1850s, the Admiralty took over the Coast Guard; officers stationed in Ireland complained that their naval career was retarded relative to those in England.
