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 Constabulary
In 1834 this force became the first dockyard police, with full police powers within the dockyards, and acting as policemen over offences committed by employees and Naval personnel within a radius of five miles of the yard. Rewards for obtaining convictions quickly led to corruption, so the force was 'cleaned up' and then abolished. The Metropolitan Police took over, and senior Naval officers became magistrates. The Royal Marine Police was formed in 1934 and subsequent changes led in 1949 to the Admiralty Constabulary being created.
