George III of Great Britain (r. 1760-1820) was the third of the Hanoverian monarchs, and he remains the longest-reigning king in British history. His six decades on the throne saw the creation of the United Kingdom, the loss of the 13 American colonies, but massive expansion of the British Empire elsewhere, and great victories such as Trafalgar against the French.
