Yes you have a point. I guess Austria wouldn't be happy with the name. They could see it as a provocation. Perhaps the new Yugoslav government would think it is wiser to choose a name that will create less diplomatic tensions, especially if they have interests toward the east & south. No need to also have a front to the west.Why not Yugoslavia? In otl, we had Yugoslavia without Bulgaria or Albania being part of it, although everyone agrees on Bulgarians being South Slavs, and many consider Albanians being South Slavic for the large part (well, at least the guys over at Paradox Interactive do, as seen in EU IV) .
I must commend you your idea of a Serbo-Bulgarian Yugoslavia is one of the most original Balkan related threads I've seen so far. I forgot to mention that in my previous post.
Depends on whether the Orthodox population in Bosnia considers themselves as Serbs in this alternate timeline, since the language is not similar anymore. Maybe they go for some kind of regional Bosnian identity.Would they try to conquer Bosnia from Austria ?
Exactly. People need to forget what happened in OTL. This Yugoslavia is a totally different animal.The point of this WI, as I understand it, is that the different linguistic makeup of this Yugoslavia would make Bosnia less attractive a target for expansion relative to Greece/Thrace.
