Note the "is a tribe which lives and ruled separately".
Note after the fall of Constantinoupolis at 4rth Crusade there were 4 Greeks major and about 6-7 minor
their names were Epirus Nice Pontus Mustras
what that mean? they were not all 4 Greeks? No surely they were but they create different rulers,
Different rules and revolt does not create nationality
the thing you must notice is that local rulers were powerfull and always wanted the love of their people,
I do not deny that in Bosnia might not be a so central Serb or Croat feeling cause big rulers were away and local pay taxes to the Big ones,
but that does not change nationality, neither a movement of autonomy,
true nationality starts when a new culture is born
the best example I can give is Dusan,
his name in History is Dusan of Serbia but his capital was Skopjie which today is Makedonia, and far from the central heart of Serbia of today?
but what that means? should we name Dusan today Dusan of Makedonia?
many here do not deny that Bosnia is nationality today,
they deny that Bosnians were pre-Slavs locals as ethnicity, and that Bosnia had nationality identification before Ottoman empire,
for many here Bosnians are Serbs and Croats who create a nationality id much later than the arrival of S Slavs in Balkans
Tribal and local rulers are not nationality,
Monaco is independent, local rulers autonomy and tribal but is it a nation?
