Admiralty in the 16th century

The Admiralty and Marine Affairs Office (1546–1707), previously known as the Admiralty Office (1414–1546), was a government department of the Kingdom of England, responsible for the Royal Navy. First established in 1414 when the offices of the separate Admiral of the North and West were abolished and their functions unified under a single centralised command, it was headed by the Lord High Admiral of England.
