The Ambitions of the Broom Family

I'm the King of England, so how did I end up in Constantinople as the Byzantine emperor?

In 1189, the Pope and the Patriarch both went mad at the same time. They demanded that Richard Plantagenet, the new King of England known as "the Lionheart" and one of the leaders of the Third Crusade, and Isaac II, the Roman Emperor, exchange their thrones, faiths, and territories. They claimed this was a divine decree from God, intended to mend the Great Schism between the Eastern and Western Churches. The crusaders were in an uproar, but Richard Plantagenet gladly accepted the proposal and went to Constantinople to be crowned Basileus.

A Crusader Kings II playthrough. The idea came from wondering what would happen if the Lionheart were the Byzantine emperor. Updates follow my in-game actions, so even the author doesn't know how things will turn out.
