January 29, 1820: Death of George III of Great Britain


On January 29, 1820, George III of Great Britain died. He was succeeded by his eldest son, George, who would become George IV of Great Britain.

George III was ill at the time. In 1810, after the death of his favorite daughter Princess Amelia, George’s health deteriorated quickly. He was already suffering from rheumatism pain and almost blind due to cataracts, but the stress made it all worse. He couldn’t rule the kingdom, so passed the Regency Act of 1811, where his son George would act as regent.

By May 1811, George was declared insane and lived at Windsor Castle in seclusion. Between this point and his death, he suffered from dementia, total blindness and deafness. He didn’t even understand that he’d been declared King of Hanover in 1814 and wasn’t stable enough to mourn the death of his beloved wife in 1818.

It was a devastating end to a relative popular monarch, even if he did lose the trust of the Colonies. Around half of the people in the Colonies still had trust in and respect for their king.


During his time of incapacitation there were fears about the line of succession. Only George’s eldest son had a legitimate heir, Princess Charlotte. When she died in childbirth in 1817, Britain was left without an heir after George’s children. The Government didn’t want the same thing to happen as did with previous dynasties, so the sons of George were encouraged to quickly marry and procreate.

George’s fourth son, Edward, became the father to Alexandrina Victoria. However, George wasn’t in a mental state to know this or in a state to mourn the death of Edward six days before his own death.
At the time of his death, George was 81 years and 239 days old. His reign lasted for 59 years and 96 days. He had the longest reign and lived longer than any of his predecessors, something that only Queen Victoria and Queen Elizabeth II have done since.


While George IV would become king, he would die 10 years later. George’s brother William became William IV but died in 1837. The crown eventually passed to Edward’s daughter Alexandrina, who decided on the name Queen Victoria of Great Britain.
