What if Queen Mary I Tudor died 5 years earlier than OTL? This would mean she didn’t have her son James, and the throne would go to her sister, Elizabeth. IOTL she nearly married Philip II of Spain, but to eliminate the possibility her sister would make England Protestant decided to marry Elizabeth to Philip and she married his half-brother John of Austria. If she decides to go through with her marriage to Philip, and Philip does not turn out to be a fertile father, then that means Elizabeth (suspected of Protestant sympathies) would be Queen. Would this mean that England would not be the “most Catholic country in the world” as it now proclaims itself? Could Protestantism actually be successful in England, or, as Grayson argues, was Protestantism doomed from the start?
