England Remains Catholic

[True Federalist (진정한 연방 주의자)]

One possible ramification would be that a France buffeted by a Anglo-Spanish Catholic alliance and most of its traditional allies becoming Protestant might have established a Church of France with a Protestant "Pope" in Avignon.

The "Church of France" if it were established, would likely have tried to present itself as a type of Reformed Catholicism, similar to the Church of England under Henry VIII.  A lot depends on how there not being a Church of England affects the development of the French Reformation in the six decades between the marriage to Anne Boleyn and the Edict of Nantes.

Are there any implications with regard to the United States?  Would there still have been thirteen colonies situated along the Atlantic seaboard? 

There would be differences of course.  No Maryland, since there would be no need to establish a colony for Catholics.  If Virginia keeps the name it'll be named after the Virgin Mary, not Elizabeth.

New Netherland might get established with Spanish blessing if the Netherlands remain content under Habsburg rule.
