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.
History of the Royal Navy
An infrastructure was also developing—by 1212 a base existed at Portsmouth, supporting at least ten ships. Later in the 13th century ships begin to be mentioned regularly as support for various campaigns under Edward I, most notably in Luke de Tany's capture of Anglesey in 1282. Edward II of England attempted to blockade Scotland, but ineffectively. Naval expenses were considerable, with twenty 120-oared galleys being ordered in 1294 because of a fear of French invasion. In 1224 the first "Admiral of England" is recorded in charters with Henry III granting the title to Sir Richard de Lucy. Four other men were granted the same title but styled differently, they were in 1263 Sir Thomas de Moleton as "Captain and Guardian of the English Seas" and in 1286 Sir William de Leybourne, as "Admiral of the English Seas" both of these offices were granted by King Edward I. In 1321 Sir Richard de Leyburn is granted the title "Admiral of England, Wales and Ireland", by Edward II and Sir John de Beauchamp, 1st Baron Beauchamp de Warwick, as "High Admiral of England" the office granted by Edward III in 1360. Although each holding the title of "Admiralis Angliae" the civil jurisdiction of their offices was never used nor did they officially receive letters patent from the monarch.
