The warrant officer corps began in the 13th century in the nascent English Royal Navy. At that time, noblemen with military experience took command of the new Navy, adopting the military ranks of lieutenant and captain. These officers often had no knowledge of life on board a ship — let alone how to navigate such a vessel — and relied on the expertise of the ship's Master and other seamen who tended to the technical aspects of running the ship. As cannon came into use, the officers also required gunnery experts.
These sailors became indispensable to the running of the ship and were rewarded with an Admiralty warrant. The warrant was a special designation, designed to set them apart from other sailors, yet not violate the class system that was prevalent during the time.
Nevertheless, while the class distinctions embodied by the distinction between commission and warrant were important at Court and in society both at home and abroad, on board ship a person's status has always depended more on the practical importance of the job that he did rather than the formalities of commission or warrant. Admiralty commissions were therefore never accorded the unique status that the Queen's commission holds in the Army, and in the hierarchy of a Royal Navy ship important warrant officers such as the Master would outrank commissioned officers such as the marine Lieutenants.
