The Regency in England was a time when King George III was considered unable to rule and his son managed as his agent as Prince Regent. On the end of George III in 1820, the Prince Regent matched George IV. The Regency served a mere nine years, from February 1811 until January 1820. In 1810, George III was born severely ill. He was pronounced incompetent of law because of mental inadequacy and the Regency Act was enacted the subsequent year getting his son George Prince Regent rule in his stead.
