Biography

George III’s six-decade rule was one of the most turbulent in British history, a period of seismic global change. He was the first Hanoverian monarch born in England, speaking English as his first language, and he cultivated an image as a devoted family man and farmer, earning the nickname 'Farmer George.' His reign, however, was dominated by conflict. The costly Seven Years' War was followed by the American Revolutionary War, which resulted in the loss of thirteen colonies—a defeat that haunted him. Later, he presided over the lengthy wars against revolutionary and Napoleonic France. From the 1780s onward, the king suffered recurrent bouts of a painful illness that caused mental confusion, violent agitation, and temporary blindness. His final descent into permanent dementia in 1811 led to his son becoming Prince Regent. Modern medical analysis suggests he likely suffered from porphyria, a blood disorder, though bipolar disorder has also been proposed. His personal tragedy became a national spectacle, shaping the monarchy and the Regency era.
