So the Rhomans invited Slavs to the Danube frontier as military settlers, and were eventually overwhelmed by them in the north, creating the basis for the Yugoslav peoples in the Balkans today. At some point, the Rhoman horde enemy of the week was the Bolgars, a Turkic people from the Volga watershed. These "barbarians" conquered large swaths of Rhoman territory and eventually ruled over Slavic and Greek subjects, centered in modern-day Macedonia. After time, the Bolgar elite began to assimilate with the local Slavic population and formed the nation of Bulgarian people. Though they were reconquered and invaded many times, the Slavic people of the southeast Balkan peninsula continued to identify as Bulgarian. My question is, if the Bolgars are kicked out of Moesia and Macedonia early, or are just overthrown by locals, what would that nation be called today? Did it have a pre-existing name? I know don't know where the names for Croatia, Servia, Poland, Bohemia, Bosnia, and the rest of the slavs came from (Slovenia, Slovakia, Slavonia make sense). If the "Bulgarians" aren't tainted by their nomadic rulers, would pan-Yugoslavism be a stronger force?
