Gfs, the Monarchy has out lasted very much in England....but, what does that prove? I suspect not much beyond people seem like having them around.

I suspect you are looking for patterns from a broad spectrum of unrelated factors, to prove some type of theory you have? IMO, this type of approach is an unlikely route to arrive at either a "fact" or any "truth", that would hold much water beyond what you have somehow conjured up "in some type of odd fashion".
