George III

George III (4 June 1738 – 29 January 1820) was a British monarch of the House of Hanover who held several distinct sovereign offices. From 25 October 1760 through 31 December 1800, he was King of Great Britain and, separately, King of Ireland. From 1 January 1801 until his death in 1820, following the union of those kingdoms, he was King of the United Kingdom of Great Britain and Ireland. He was concurrently Prince-elector of Brunswick-Lüneburg (commonly known as the Electorate of Hanover) from 1760. The Hanoverian territories experienced foreign occupation during the Napoleonic Wars; after the dissolution of the Holy Roman Empire in 1806, the electoral title continued to be used until the lands were raised to the Kingdom of Hanover. From 1814 to 1820, George III was the first King of Hanover. The British and Hanoverian states remained politically distinct despite sharing a sovereign (personal union). From 1811 the Prince Regent, later George IV, exercised royal powers in the United Kingdom. William Wyon's 1817 'Incorrupta' pattern crown belongs to the period of George III's British reign. The reign periods associated with each country do not imply uninterrupted personal exercise of government throughout those years.
