Killer Kings (2025) : 1x3

Bad King John I - the Medieval Monster - was far worse in real life that the fictitious villain of the Robin Hood legend. Even before he was crowned King in 1199, he had a dreadful reputation. This was the Prince who, when he learned that his brother ‘Good King Richard’ the “Lionheart” had been imprisoned on return from crusade, decided to tell people he was dead so that he could rule instead.
