The office of Admiral of England (later Lord Admiral, and later Lord High Admiral) was created around 1400; there had previously been Admirals of the northern and western seas. King Henry VIII established the Council of the Marine—later to become the Navy Board—in 1546, to oversee administrative affairs of the naval service. Operational control of the Royal Navy remained the responsibility of the Lord High Admiral, who was one of the nine Great Officers of State. This management approach would continue in force in the Royal Navy until 1832.
