The Proclamation of Rebellion, officially titled A Proclamation for Suppressing Rebellion and Sedition, was the response of George III of Great Britain to the news of the Battle of Bunker Hill at the outset of the American Revolutionary War. Issued August 23, 1775, it declared elements of the American colonies in a state of "open and avowed rebellion." It ordered officials of the British Empire "to use their utmost endeavours to withstand and suppress such rebellion." The Proclamation also encouraged subjects throughout the Empire, including those in Great Britain, to report anyone carrying on "traitorous correspondence" with the rebels so that they could be punished.
