January 29, 1820: King George III Dies.
After ten years of resignation from public life due to his mental illness, King George III, the British King who lost the American colonies dies, at the age of 82.
In 1720 at the age of 20 George rose to power, succeeding his grandfather George II. King George III coercive policy against the American Colonies lead to the outbreak of the American War for Independence.
The loss of England’s most profitable colony led to many opposition to the king. After William Pitt (the younger) ascended to power in Parliament the king retired from active participation in government, with the exception of his interference when issues such as Catholic Emancipation rose up.
In the winter of 1788-89 the king suffered from a prolonged mental illness and by 1810 he was mentally insane. It is speculated that King George III suffered from porphyria, a defect in the blood that can lead to mental illness if not treated. King George spent the rest of his life in the care of his wife, Charlotte Sophia, whom he married in 1761. Upon King George III death his son, the Prince of Wales ascended to power as King George IV.
