The USA is also a remnant of a dismembered entity (or rather composed of one). I can't think of any country that has remained exactly the same throughout history. Nearly every country out there is either an agglomeration of formerly independent entities or used to be part of a bigger entity at some point. Your categories are useless. Unless you're trying to define categories for countries which don't exist.
