And? That doesn’t make it the first Protestant nation. It was actually one of the last. Your original claim was, “The only Protestant nation ever created, was the greatest nation ever created.”
Great Britain was created SPECIFICALLY as a Protestant nation. It is still part of the UK’s laws. I think you need to learn more history.
Britain and Brits had been there before and had been Catholic before it broke free from the power of the Roman empire, America was the first and only time that Catholicism was totally left out of the creation of a new nation, it bordered of course on a nation that had the more traditional Catholic background, Mexico.
