Piracy is an offence against the universal law of society, a pirate being according to Sir Edward Coke, _stis humani generis_. As, therefore, he has renounced all the benefits of society and government, and has reduced himself to the savage state of nature, by declaring war against all mankind, all mankind must declare war against him; so that every community has a right by the rule of self-defense, to inflict that punishment upon him which every individual would in a state of nature otherwise have been entitled to do, for any invasion of his person or personal property. By various statutes in England and the United States, other offences are made piracy. Thus, if a subject of either of these nations commit any act of hostility against a fellow subject on the high seas, under color of a commission from any foreign power, this act is piracy. So if any captain of any vessel, or mariner, run away with the vessel, or the goods, or yield them up to a pirate voluntarily, or if any seaman lay violent hands on his commander, to hinder him from fighting in defence of the ship or goods committed to his charge, or make a revolt in the ship, these offences are acts of piracy, by the laws of the United States and England. In England by the statute of 8 George I, c. 24, the trading or corresponding with known pirates, or the forcibly boarding any merchant vessel, (though without seizing her or carrying her off,) and destroying any of the goods on board, are declared to be acts of piracy; and by the statute 18 George II. c. 30, any natural born subject or denizen who in time of war, shall commit any hostilities at sea, against any of his fellow subjects, or shall assist an enemy, on that element, is liable to be punished as a pirate. By statute of George II. c. 25, the ransoming of any neutral vessel, which has been taken by the captain of a private ship of war, is declared piracy. By the act of congress, April 30, 1790, if any person upon the high seas, or in any river, haven, or bay, out of the jurisdiction of any particular state, commit murder or robbery, or any other offence which if committed within the body of a county, would by the laws of the United States, be punishable by death, such offender is to be deemed a pirate. By the act of congress, 1820, c. 113, if any citizen of the United States, being of the crew of any foreign vessel, or any person being of the crew of any vessel owned in whole or part by any citizen of the United States, shall be engaged in the foreign slave trade, he shall be adjudged a pirate. Notwithstanding the expression used in this statute, the question, says Chancellor Kent, remains to be settled, whether the act of being concerned in the slave trade would be adjudged piracy, within the code of international law. In England by the act of parliament passed March 31, 1824, the slave trade is also declared to be piracy. An attempt has been made to effect a convention between the
