@izzythepush,
Henry VIII was never a Protestant, he was given the title Defender of the Faith by the Pope, a title that still appears on UK coins today.
He made himself head of the church in England, not head of the Church of England. England did not become properly protestant until Edward VI.
Shakespeare penned the play King John during the reign of Elizabeth I. Now when most people think of King John they think of Robin Hood, the revolt of the barons and the signing of the Magna Carta, but there’s not a lot about that in the play.
Instead Shakespeare writes about the problems John had with Rome, similar to Elizabeth, at one point John contacted the Moroccan sultan to discuss converting the country to Islam. It was never taken seriously, but things may have been very different.
