John Murray, 4th earl of Dunmore (born 1730?—died Feb. 25 or Mar. 5, 1809, Ramsgate, Kent, Eng.) was the British royal governor of Virginia on the eve of the American Revolution.
A descendant of the Scottish house of Stuart, he was the eldest son of William Murray, the 3rd earl, whom he succeeded in 1756. He sat in the House of Lords from 1761 to 1770 and then was appointed governor first of New York in 1770 and then of Virginia in 1771. Personally interested in western lands as well as officially concerned with protection of the Virginia frontier to the west, he raised 3,000 militiamen to subdue the Shawnee Indians in the upper Ohio River valley in 1774, an action known as Lord Dunmore’s War.
As the revolution approached, Dunmore’s power declined rapidly, especially through his own rashness. He dissolved the Virginia Assembly in 1772, 1773, and 1774 on account of its revolutionary sentiments. In April 1775 he seized the colony’s store of powder, thereby bringing about an armed uprising. Taking refuge aboard an English warship, he shortly declared martial law, proclaimed freedom to slaves who would join the British, and proposed to Lord Dartmouth the use of Indians against the rebels. Defeated at Great Bridge near Norfolk on Jan. 1, 1776, he ordered his ships to bombard Norfolk, thereby setting it afire. He returned to England in July 1776. After serving again in the House of Lords, he was royal governor of the Bahamas from 1787 to 1796.
