Enforcement of military or naval service on unwilling men. Until the early 19th century, it flourished in port towns everywhere, as “recruiters” searched through waterfront boardinghouses, brothels, and taverns. They often chose vagabonds or prisoners. Impressed men were forced into service through violence or coercion and were held to their duty by brutal discipline. In the early 19th century, Royal Navy ships halting U.S. vessels to search for British deserters frequently impressed naturalized U.S. citizens, one cause of the War of 1812. Impressment declined in the 19th century as states adopted more systematic recruiting methods. Seealso conscription.

One of the largest impressment operations occurred in the spring of 1757 in New York City, then still under British colonial rule. Three thousand British soldiers cordoned off the city, and plucked clean the taverns, and other sailors' gathering places. "All kinds of tradesmen and Negroes" were hauled in, nearly eight hundred in all. Four hundred of these were "retained in the service".
All three groups also dealt with high levels of desertion, as seamen moved about frequently, looking for the best deal, and the most comfortable working conditions. In the middle of the 18th century, desertion rates on naval ships were about the same for volunteers and pressed men; starting high, then falling heavily after a few months onboard a ship, and generally becoming negligible after a year — navy pay ran months or years in arrears, and desertion might mean not only abandoning companions in the ship's company, but also the loss of a large amount of money already earned (though authorities were sometimes lenient on this point). If a navy ship had taken a prize, a deserting seaman would also forfeit his share of the prize money.
In addition to impressment, England also used the Quota System (or The Quod) from 1795 to 1815, whereby each county was required to supply a certain number of volunteers, based on its population and the number of its seaports. Unlike impressment, the Quota System often resulted in criminals, or inexperienced landsmen, serving on board ship.
Impressment was usually abandoned in peacetime, since there was a surplus of seamen available and willing to work in the navy, and merchant ship salaries usually fell, making them a less attractive alternative.
During the wars with France (1793 to 1815), the Royal Navy aggressively reclaimed British deserters on board ships of other nations, both by halting and searching merchant ships, and, in many cases, by searching American port cities. While non-British subjects weren't impressed, Britain didn't recognise naturalised American citizenship, and treated anyone born a British subject as still "British" — as a result, the Royal Navy impressed over 6,000 sailors who claimed to be American citizens. While not directly mentioned as a reason for the declaration of war in the War of 1812, impressment caused serious diplomatic tension, and helped to turn American public opinion against Britain.
The first act legalising this practice was passed in the reign of Queen Elizabeth in 1563 and was known as "an act touching politick considerations for the maintenance of the navy". It was renewed many times until 1631. In the Vagabonds Act 1597, several lists of persons were subject to impressment for service in the fleet. The Recruiting Act 1703 was an act passed "for the increase of seamen and better encouragement of navigation, and the protection of the Coal Trade". This act gave parish authorities the power to apprentice boys to the sea, and reaffirmed rogues and vagabonds were subject to be pressed into the navy. In 1740, impressment was limited to men between eighteen and forty-five, and it also exempted foreigners. The last law was passed in 1835, in which the power to impress was reaffirmed. This law limited the length of service of a pressed man to five years, and added the provision that a man couldn't be pressed twice. Although Britain abandoned the practice of impressment in 1815, impressment remained legal until the early 1900s. The various laws authorising impressment haven't been repealed.
In 1708, parliament passed a law forbidding impressment in American waters, without clearly stating whether the law applied only to the navy, or to civil authorities as well, and whether it applied only to the current war or to all future wars. Two attorneys general of Great Britain, one in 1716, and another in 1740, issued opinions that the law was no longer in effect, but many American colonists disagreed. As a result of the doubt over the legality of impressment in American waters, parliament passed a new law in 1746, stating that impressment was forbidden in the West Indies, but not in America, leading to a riot in Boston the following year, and continued with the colonies, particularly New England.
Starting in 1645, the New Model Army raised by Oliver Cromwell to overthrow Charles I during the English Civil War was largely manned by impressment.
After the restoration of the monarchy, impressment into the army was discontinued.
During the American Revolutionary War, after the losses at the Battle of Saratoga and the apprehended hostilities with France, the existing voluntary enlistment measures were judged to be insufficient. Between 1775 and 1781, the regular army increased from 48,000 to 110,000. Two acts were passed, the Recruiting Act 1778 and the Recruiting Act 1779 for the impression of individuals into the British Army. The chief advantages of these acts was in the number of volunteers brought in under the apprehension of impressment. To avoid impressment, some recruits incapacitated themselves by cutting off the thumb and forefinger of the right hand. The Recruiting Act of 1779 was repealed on May 26, 1780, and army impressment was permanently discontinued.
During the experiment, the British government allowed army impressment under severely restricted circumstances — both acts emphasised volunteering over impressment, and offered strong incentives to volunteers. The impressment portion of the 1778 act applied only to Scotland and the area around London, excluding Wales and the rest of England, to avoid interfering with harvesting. The 1779 act applied to all of Great Britain, but was initially suspended everywhere except the area around London, and actually applied to all of Great Britain for only six months, until the 1779 act was repealed in May 1780, and army impressment ceased in Britain.
Unlike naval impressment, army impressment applied only to "able-bodied idle, and disorderly Persons, who could not, upon Examination, prove themselves to exercise and industriously follow some lawful Trade or Employment, or to have some Substance sufficient for their Support and Maintenance", as well as smugglers, according to the 1778 law, but excluding from that any men who were voters, or harvest workers. The 1779 law extended impressment also to "incorrigible rogues" who had abandoned their families, and left them as expenses on the parish.
Impressed apprentices were released under appeal from their masters, and impressed foreigners were released when requested by their countries' embassies.
