Dunmore's Proclamation

Dunmore's Proclamation is a historical document signed on November 7, 1775, by John Murray, 4th Earl of Dunmore, royal governor of the British colony of Virginia. The proclamation declared martial law in the colony, and promised freedom for "all indented servants, negroes, or others", who joined the British Army (see also Black Loyalists). Most relevant historians agree that the proclamation was chiefly designed for practical rather than moral reasons.

Formally proclaimed on November 15, its publication prompted between 800 and 2,000 slaves (from both Patriot and Loyalist owners) to run away and enlist with Dunmore. It also raised a furor among Virginia's slave-owning elites (including those who had been sympathetic to Britain), to whom the possibility of a slave rebellion was a major fear. The proclamation ultimately failed in meeting Dunmore's objectives; he was forced out of the colony in 1776, taking about 300 former slaves with him.

Later British commanders over the course of the American Revolutionary War followed Dunmore's model in enticing slaves to defect—the 1779 Philipsburg Proclamation, which applied across all the colonies, was more successful. By the end of the war, at least 20,000 slaves had escaped from plantations into British service.
