In the British TV series "Blackadder the Third", Hugh Laurie played which future British monarch?

"Blackadder the Third" is the third series of the BBC sitcom Blackadder, written by Richard Curtis and Ben Elton, which aired from 17 September to 22 October 1987. The series was set during the Georgian Era, and saw the principal character, Mr. E. Blackadder serve as butler to the Prince Regent and have to contend with, or cash in on, the fads of the age embraced by his master.

The third series reduced the number of principal characters again compared with the previous series, but instead included a number of significant cameo roles by well-known comic actors. The programme won a BAFTA award for Best Comedy Series in 1988 and received three further nominations.

"Blackadder the Third" is set in the late 18th and early 19th centuries, a period known as the Regency. For much of this time, King George III was incapacitated due to poor mental health, and his son George, the Prince of Wales, acted as regent. During this period, he was known as "the Prince Regent". Hugh Laurie played the part of George, Prince Regent.

George IV (George Augustus Frederick; 12 August 1762 – 26 June 1830) was King of the United Kingdom of Great Britain and Ireland and King of Hanover following the death of his father, King George III, on 29 January 1820, until his own death ten years later.
