Short Biography

Madness of King George III

King George III suffered his first bout of mental instability in 1788. Ten years later the affliction recurred and was so bad that Queen Charlotte was frightened of her husband. In February 1789 Parliament passed the Regency Bill which declared the King’s eldest son, Prince George to become Regent if the King’s mental capacity was permanently reduced. However, the King recovered and the Bill was not enacted.

In 1804 the King suffered another brief period of mental instability. Six years later, there was a recurrence that would not respond to treatment and Prince George was declared Regent of Britain.

King George III died on 29th January 1820 at Windsor Castle. He was succeeded by the Prince Regent who took the throne as King George IV.
