History

From at least 1580, the lieutenant on a ship had been the officer immediately subordinate to the captain. Before the

English Restoration The Restoration of the Stuart monarchy in the kingdoms of England, Scotland and Ireland took place in 1660 when King Charles II returned from exile in continental Europe. The preceding period of the Protectorate and the civil wars came to ...

, lieutenants were appointed by their captains, and this inevitably led to abuses and to the widespread appointment of men of insufficient qualification. In 1677,

Samuel Pepys Samuel Pepys (; 23 February 1633 – 26 May 1703) was an English diarist and naval administrator. He served as administrator of the Royal Navy and Member of Parliament and is most famous for the diary he kept for a decade. Pepys had no marit ...

, while he was Chief Secretary to the Admiralty, introduced the first examination for lieutenant, and thereafter their seniority was dated from the passing of this examination. A lieutenant was numbered by his seniority within the ship on which he served, so that a frigate (which was entitled to three) would have a first, a second, and a third lieutenant. A first-rate ship was entitled to six, and they were numbered accordingly. At first, a lieutenant's commission was given only for the particular ship in which he served, but after the loss of HMS ''Wager'' in 1741 and the subsequent mutiny, the

changed its policy and lieutenants were given more general commissions upon passing their examination. During the early days of the naval rank, some lieutenants could be very junior indeed, while others could be on the cusp of promotion to captain; those lieutenants ranged across present-day army ranks from a second lieutenant through to a lieutenant colonel. As the rank structure of navies stabilized, and the ranks of commander, lieutenant commander, and sub-lieutenant (or lieutenant, junior grade in the U.S. services) were introduced, the rank of naval lieutenant became less wide-ranging and is today the equivalent of an army captain.

"First lieutenant" in naval usage

The first lieutenant (1st Lt or 1LT) in the

and other Commonwealth navies, is a post or appointment, rather than a rank. Historically, the lieutenants in a ship were ranked in accordance with seniority, with the most senior being termed the first lieutenant and acting as the
