<P> Impressment, colloquially, "the press" or the "press gang", refers to the act of taking men into a military or naval force by compulsion, with or without notice . Navies of several nations used forced recruitment by various means . The large size of the British Royal Navy in the Age of Sail meant impressment was most commonly associated with Britain . It was used by the Royal Navy in wartime, beginning in 1664 and during the 18th and early 19th centuries as a means of crewing warships, although legal sanction for the practice can be traced back to the time of Edward I of England . The Royal Navy impressed many merchant sailors, as well as some sailors from other, mostly European, nations . People liable to impressment were "eligible men of seafaring habits between the ages of 18 and 55 years". Non-seamen were impressed as well, though rarely . </P> <P> Impressment was strongly criticized by those who believed it to be contrary to the British constitution; at the time, unlike many of its continental rivals, British subjects were not subject to conscription for any other military service, aside from a brief experiment with army impressment from 1778 to 1780 . Though the public opposed conscription in general, impressment was repeatedly upheld by the courts, as it was deemed vital to the strength of the navy and, by extension, to the survival of the British influence and realm . </P>
