England’s longest-ruling monarch before Queen Victoria, King George III (1738-1820) ascended the British throne in 1760. During his 59-year reign, he pushed through a British victory in the Seven Years’ War, led England’s successful resistance to Revolutionary and Napoleonic France, and presided over the loss of the American Revolution. After suffering intermittent bouts of acute mental illness, he spent his last decade in a fog of insanity and blindness.
