King George 111 was born George William Frederick on 4th June 1738 and was King of Great Britain and Ireland from 1760, until the union of these two countries in 1801; after which he became King of the United Kingdom of Great Britain and Ireland until his death in 1820. He also became King of Hanover in 1814, but unlike his two Hanoverian predecessors, he was born in Britain, spoke English and never actually visited Hanover at all.
George 111 lived and reigned longer than any previous monarch and was involved in several military conflicts. Shortly after he came to the throne, Great Britain defeated France in the Seven Years War. Further wars with France concluded in 1815 with the defeat of Napoleon at the Battle of Waterloo.
Later in life he suffered from mental illness, and recent medical opinion believes that the cause could have been the blood disease porphyria. After a relapse in 1810, his eldest son George, Prince of Wales, ruled as Prince Regent until his father\'s death in 1820 when he became King George 1V.
London silver produced during the reign of George 111 displays the Leopard\'s Head Crowned within the hallmark, as distinct from later London Georgian silver which only shows a bare leopard\'s head.
