I'll pretend to be an outsider who has no clue about history of the Balkans, and here I am asking, based on what facts have you concluded that Bosnian identity didn't emerge prior to the conversions to Islam?
Good lord did you even read any of my previous posts?
Okay once more, the most simplified viewpoint of an outsider, not being an "expert" on the history of Balkans, on the earliest history of Balkans.
1) Cca 700 AD great number of various slavic tribes tribes settle an area, which includes regions between Istria and Thrace (
map). At this time we can easily claim that all these tribes shares the same culture.
2)Over the course of next 3 centuries these tribes are exposed to dramatic regional instability. Due to this they are split on the western and eastern parts, depending of what branch of christianity they follow. The vast number of catholic tribes could be identified as croats and the "orthodox" tribes could be identified as serbs (based on the two major tribes). Two maps
here and
here I've found show the borderlines the christian shcism (at those times).
3) As the power of Byzantine empire was shrinking over next 4 centuries, the influence of catholicism slowly expanded east (but realy slowly). Number of realms emerged and their borders were changing very often(no need map we all remember how EU3 startup looked like). The slavs living here still shared only one major distinction - influence of Roma or influence of Constantinople. True there probably were differencies between inhabitants of i.e. Zeta and inhabitans of i.e. Hum, but there were minor and could be compared to differencies between the russian inhabitants of i.e. Tver and i.e. Pskov.
4) What happened after year 1400 is absolutely unimportant for our discussion.
Conclusion: At the the time EUIV starts, there were only two major slavic culture groups - the catholic one which we name Croats (as calling them "catholic south slavs" would make as much sense as calling Austrians "south-eastern germans") and the "orthodox" one which we call Serbs. There were no Istrians, Dalmatians, Ragusans, Montenegrians, Dukljans and of course no Bosnians.
And the end of the post allow me to cite my personal opinion what is realy the problem here. I believe that if both Kingdom of Bosnia and Kingdom of Serbia had both "orthodox south slavic" culture this thread wouldn't exist. The one and only problem here is the term "Serbian", which you as Bosnian nationalists can't accept. This is understendable, but from historic point of view absolutely redundant.
