George III
King of Great Britain and Ireland from 1760 to 1820 (1738–1820)
George III (George William Frederick; 4 June 1738 – 29 January 1820) was King of Great Britain and Ireland from 25 October 1760 until his death in 1820. During his reign, the Acts of Union 1800 merged Great Britain and Ireland into the United Kingdom. He was concurrently duke and prince-elector of Hanover in the Holy Roman Empire before becoming King of Hanover on 12 October 1814. He was the first monarch of the House of Hanover who was born in Great Britain, spoke English as his first language, and never visited Hanover.
George was born during the reign of his paternal grandfather, King George II, as the first son of Frederick, Prince of Wales, and Princess Augusta of Saxe-Gotha. Following his father's death in 1751, Prince George became heir apparent and Prince of Wales. He succeeded to the throne on George II's death in 1760. The following year, he married Princess Charlotte of Mecklenburg-Strelitz, with whom he had 15 children. George III's life and reign 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.

Why this record matters
“George III” is worth following because a concise public description often conceals a longer documentary argument. Here, George, King and Great provides the most credible route into that argument.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q127318. VIAF identifies the subject as 49264990. The Library of Congress control number is n79061402. 3 of 4 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1738, 1820, 1760 and 1800.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
