Born 1738 – Died 1820 • King of Great Britain 1760 - 1820

George III was King of Great Britain and Ireland from 25 October 1760 until the union of the two countries on 1 January 1801, after which he was King of the United Kingdom of Great Britain and Ireland until his death. He was concurrently Duke and prince-elector of Brunswick-Lüneburg ("Hanover") in the Holy Roman Empire until his promotion to King of Hanover on 12 October 1814. He was the third British monarch of the House of Hanover, but unlike his two predecessors he was born in Britain, spoke English as his first language, and never visited Hanover.

His life and with it his reign, which were longer than any other British monarch before him, were marked by a series of military conflicts involving his kingdoms, much of the rest of Europe, and places farther afield in Africa, the Americas and Asia. Early in his reign, Great Britain defeated France in the Seven Years' War, becoming the dominant European power in North America and India. However, many of Britain's American colonies were soon lost in the American War of Independence. Further wars against revolutionary and Napoleonic France from 1793 concluded in the defeat of Napoleon at the Battle of Waterloo in 1815.

In the later part of his life, George III had recurrent, and eventually permanent, mental illness. Although it has since been suggested that he had the blood disease porphyria, the cause of his illness remains unknown. After a final relapse in 1810, a regency was established, and George III's eldest son, George, Prince of Wales, ruled as Prince Regent. On George III's death, the Prince Regent succeeded his father as George IV.

Historical analysis of George III's life has gone through a "kaleidoscope of changing views" that have depended heavily on the prejudices of his biographers and the sources available to them. Until it was reassessed in the second half of the 20th century, his reputation in the United States was one of a tyrant; and in Britain he became "the scapegoat for the failure of imperialism".

George III lived for 81 years and 239 days and reigned for 59 years and

96 days: Both his life and his reign were longer than those of any of his predecessors. Only Victoria and Elizabeth II have since lived and reigned longer.

George III was dubbed "Farmer George" by satirists, at first to mock his interest in mundane matters rather than politics, but later to contrast his homely thrift with his son's grandiosity and to portray him as a man of the people. Under George III, the British Agricultural Revolution reached its peak and great advances were made in fields such as science and industry. There was unprecedented growth in the rural population, which in turn provided much of the workforce for the Industrial Revolution. George's collection of mathematical and scientific instruments is now housed in the Science Museum, London. He had the King's Observatory built in Richmond-upon-Thames for his own observations of the 1769 transit of Venus. When William Herschel discovered Uranus in 1781, he at first named it Georgium Sidus (George's Star) after the King, who later funded the construction and maintenance of Herschel's 1785 40-foot telescope, which was the biggest ever built at the time.

While very popular at the start of his reign, by the mid-1770s George

had lost the loyalty of revolutionary American colonists which led to the United States Declaration of Independence.
