, especially those who had been promoted from among a ship's crew. By contrast, those with Parliamentary supporters or family connections were more likely to spend only a nominal period as master and commander of a sloop, before being elevated to post-captain. From 1718, the Navy List began recording an officer's date of appointment to the rank of master and commander, with the intention of establishing seniority as a guide to promotion, but there is little evidence that this carried through into actual appointments. Over the later eighteenth century, the rank evolved into a more regular stage of service between lieutenant and captain. The Royal Navy shortened 'master and commander' to 'commander' in 1794; however, the term 'master and commander' remained (unofficially) in common parlance for several years. The term 'master commanding' (abbreviated as 'master com.' or 'mast. com.') was still recognised in 1851, with the Navy List for that year listing 21 ships commanded by Masters with this appellation . The rank of commander was a popular recognition of service during the
