Prince Edmund Plantagenet, Duke of Edinburgh, or The Black Adder was the main character in the first series and the first Blackadder shown in the series. He was the son (possibly step-son) of King Richard IV and, as a Prince of the Realm, was second in the line of succession to the Throne of England. He also served for a time as the Archbishop of Canterbury and, for only 30 seconds before his death, was the King of England after the whole of his family had been unintentionally poisoned by Percy, the Prince drinking from the same goblet and soon died, ending his reign before it could even begin. He was also the great-grandfather of Lord Edmund Blackadder.
