George Hamilton-Gordon 4th earl of Aberdeen
(born Jan. 28, 1784, Edinburgh, Scot. — died Dec. 14, 1860, London, Eng.) British foreign secretary and prime minister (1852 – 55). As special ambassador to Austria in 1813, he helped form the coalition that defeated
Napoleon. As foreign secretary (1828 – 30, 1841 – 46), he settled boundary disputes between Canada and the U.S. with the
Webster-Ashburton Treaty and the Oregon Treaty (
see Oregon Question). As prime minister, he formed a coalition government, but his indecision hampered peacekeeping efforts and led to Britain's involvement in the
Crimean War. Constitutionally responsible for the mistakes of British generals in the war, he resigned in 1855.
