During the King's minority, Archibald Douglas, 5th Earl of Douglas was Regent. In 1440, after his death, Crichton and Sir Alexander Livingston invited the 16-year-old William Douglas, 6th Earl of Douglas and his brother to dinner in Edinburgh Castle, and murdered them, despite the young King's pleas for their lives. This brutal incident of murder and betrayal of hospitality has become known as the ‘Black Dinner’ and was an inspiration for the "Red Wedding" massacre in the Game of Thrones series.
