TheProhibitory Act 1775 (16 Geo. 3. c. 5) was an act of theParliament of Great Britain in late 1775 which cut off all British trade with the rebelliousThirteen Colonies and instituted ablockade around the colonies, along with authorizing British vessels to seize colonial ships.[1] In the text of the act, it referenced two acts passed by the last session of Parliament which were known as theRestraining Acts 1775. Issued after the outbreak of theAmerican War of Independence in April 1775 with theBattles of Lexington and Concord, AmericanPatriots responded to the act by issuingletters of marque toprivateers, and it was referenced as one of the27 colonial grievances of the United States Declaration of Independence.
In October 1775, the Parliament of Great Britain, under theNorth ministry, decided that sterner measures would be taken to subdue the rebellion now underway in the Thirteen Colonies. To that end, they decreed a blockade against the colonies' trade by passing the Prohibitory Act. "All manner of trade and commerce" would be prohibited, and any ship that was found trading "shall be forfeited to his Majesty, as if the same were the ships and effects of open enemies." The act's goal was to weaken the colonial economy by cutting of its trade. Amounting to a virtual declaration of war,John Adams regarded the act as the straw that broke the camel's back.[2]
The act served as an effective declaration of war on the colonies since a blockade is anact of war under thelaw of nations. The colonies andContinental Congress immediately reacted by issuing letters of marque, which authorized individual American shipowners to seize British ships in a practice known as privateering.[citation needed]
At the same time, the British had hired German auxiliary troops known asHessians, which were being sent to the colonies to suppress the rebellion. They also made overtures to variousIndian tribes requesting their support in the conflict. Concluding that they no longer had the king's protection, Patriot colonists responded with the Declaration of Independence.[3]
It throws thirteen colonies out of the royal protection, levels all distinctions, and makes us independent in spite of our supplications and entreaties.... It may be fortunate that the act of independency should come from the British Parliament rather than the American Congress.[4]
— John Adams
The whole act was repealed by section 1 of, and the schedule to, theStatute Law Revision Act 1861 (24 & 25 Vict. c. 101).
