Wasn’t that King Edward they beheaded on Black Adder?
By accident of course.
No, it was Richard:
The Black Adder) (1): The least intelligent (while highest-ranked) of the Blackadder clan depicted in the series. On becoming Prince he initially wanted to be called “Black Vegetable” before Baldrick convinced him it was a bad idea. He killed King Richard and kept seeing his ghost. He became Duke of Edinburgh and Lord of the Privy. It is a question as to whether or not he was born from the new king or from his mother having an affair. At one point he became the Archbishop of Canterbury, but, was eventually fired, to his relief. He married the 9-year-old Princess Leia of Hungary, which he wasn’t 100% pleased about. He possibly has some witch-blood in him since his mother has learnt voodoo. He was eventually dethroned as Duke of Edinburgh and gathered the other 6 evilest men in all England and they became the Black Seal. They planned to kill the royal family (except Edmund) and claim the throne. Instead they betrayed Edmund. Edmund had his ears and hands cut off before a spike went up his back-side and the twist went for his privates. All his family and the Black seal drank poison and died, making him king. But, 30 seconds later, he drank poison and died. He was very cowardly and often didn’t think things through. He despises, but, fears his family and dislikes Lord Percy. His best friend is Baldrick, but even he is considered a smelly fool.
