I
don't understand you very well here. Many language (mostly
European)are having nation marks (English, French, German, Russian,
Albanina, Greek, Italian, ....)
You forgot that German is spoken in Germany, Austria, Switzerland and
Italy all three happily living together on one wiki - and of course:
there are some differences among these four versions of German, but
nevertheless they are ONE language.
French is spoken in France, Canada, Switzerland etc. and they work on
one Wikipedia.
Dutch is spoken in the Netherlands, Belgium and France and they work on
one Wikipedia.
Italian is spoken in Italy and Switzerland and they work on one Wikipedia.
English is spoken in Great Britain, USA, Australia, New Zealand etc. and
they all work on one Wikipedia.
That is very specific case, As in Switzerland live Italians, Germans and
Franks. In Montenegrin case in Montenegro lives 45% Montenegrin s, 35%
Serbs, Albanians, Bosnnjaks,...
On other cases those countries was colonies of mayor European empires.
