You're thinking of Henry VIII, who caused the Anglican church to be separated from the Roman Catholic Church. And he wasn't denying God in any way, shape or form: only the Pope.
He still believed in God, feared Him, and worshiped Him.
No I'm not, I know about the protestant reformation, it's one of the fundamental things we learn when we learn the history of our country. I mean a king before Henry VIII by quite a bit, a few hundred years I think.
