cantabria is in non mediterranean spain i understand that there might be very specific ways of referring to canatabria as linked to spain politically and therefore politically mediterranean but this is certainly not obvious by the way you give no source for your remarks implying that there is a definition of a mediterranean community so i am assuming that this is just being conversational anyway political definitions seem quite inappropriate in an article about such timespans of human history you should look at how the terms are defined in wikipedia and other places if the interpretation of the terminonology is ambiguous we have a choice of putting in extra verbiage to make it clear or else seeking a word which gets rid of ambiguity southern europe would work though
