There's that whole thing about England being somewhat Orthodox/schismatic prior to William of Normandy's usurpation of the throne in 1066, whereupon he agreed to hold the crown as a fief of the Papacy. This tentatively remained unchanged until Henry VIII broke with Rome and asserted England was an "empire", though it seems to me England was universally seen as heretic/Protestant after that, as opposed to schismatic - even when Elizabeth assured King Philip she differed from him on only a handful of theological questions.
What would be the most plausible POD for an Orthodox England post-1066? What if Richard Lionheart married the Byzantine princess (the damsel of Cyprus, daughter of Isaac Dukas Comnenus) and she came to rule the Angevin empire as regent for their children? Or something like that. Or would it be necessary to wait until the Reformation and the Tudors?
