PRIVATEER. A vessel owned by one or more private individuals, armed and equip ped at his or their expense, for the purpose of carrying on a maritime war, by the au thority of one of the belligerent parties.
A privateer is a private vessel commis sioned by the state by the issue of a letter of marque to its owner to carry on all hos tilities by sea, presumably according to the laws of war. She continues under the con trol of her private owner, and her crew are under the same discipline as the crew of a merchant ship. Formerly a state issued let ters of marque to its own subjects, and to those of neutral states as well, but a priva teersman who accepted letters of marque from both belligerents was regarded as a pirate.
For the purpose of encouraging the own ers of private armed vessels, they are usu ally allowed to apprOpriate to themselves the property they capture, or, at least, a large' proportion of it ; 1 Kent 96.

By the Declaration of Paris (q. v.) pri vateering was abolished, but the United States, Spain, Mexico, and Venezuela did not accede to this declaration.
The creation of a volunteer navy by a belligerent was not prohibited by the Declara tion of Paris. A volunteer cruiser is a ves sel loaned by her private owner to the state. Her officers are commissioned and her crew are subject to the discipline of a ship of war ; she only resembles a privateer in that her prizes belong to her owner. In 1870, when Prussia proposed the creation of a vol unteer navy, the French government protest ed, but the English government held that such a navy was to be distinguished from privateers, and that their employment was no evasion of the Declaration of Paris; but from this opinion Phillimore decidedly dis sented.

The Convention Relative to the Conversion of Merchant-Ships into War-Ships, adopted at The Hague in 1907, defines the conditions subject to which merchant-ships may be in corporated into the fighting fleet of a state in time of war. Such ships must be under the direct authority and immediate control of the power whose flag they fly ; they must bear the external marks which distinguish the war-ships of their nationality ; their com manders must be duly-commissioned officers in the service of the state ; their crews must be subject to the rules of military discipline; they are bound to observe in their operations the laws and customs of war ; and their names must figure on the list of the ships of the military fleet of the belligerent. Hig gins, The Hague Peace Conferences, 308-321.
A merchant vessel without any commis sion may become a lawful combatant in self defence, and if she captures her assailant, the latter may be condemned as lawful prize.
During the civil war in Amerrea, congress authorized the president to issue letters of marque, but he did not do so. The confeder ates offered their letters of marque to for eigners, but they were not accepted. The confederate vessels were commissioned as of its regular navy. Boyd's Wheat. Int. Law.
The president's proclamation at the out break of the Spanish-American war, 1898, declared that privateering would not be re sorted to by the United States.
It has been thought that the constitutional provision empowering congress to issue let ters of marque deprives it of the power to join in a permanent treaty abolishing priva teering. See 28 Am. L. Rev. 615 ; 24 id. 902; 19 Law Mag. & Rev. 35.
