Lords Admiral were appointed from the 15th century; they were later styled "Lords High Admiral" until the 18th century, and Lords Commissioners of the Admiralty from the 17th century, as the governors of the English and later British Royal Navy. From 1683 to 1684, there were seven paid Commissioners, and one unpaid supernumerary Commissioner. The number varied between five and seven Commissioners through the 18th century. The standing of all the Commissioners was in theory the same, although the First Commissioner or First Lord exercised an ascendancy over his colleagues from an early date.
