Originally titled the "Senior Naval Lord to the Board of Admiralty" when the post was created in 1689,[5] the office was re-styled "First Naval Lord" in 1771.[6] The concept of a professional "First Naval Lord" was introduced in 1805,[7] and the title of the office was changed to "First Sea Lord" on the appointment of Sir John Fisher in 1904. Since 1923, the First Sea Lord has been a member of the Chiefs of Staff Committee; he now sits on the Defence Council and the Admiralty Board.[8]
