Nice try once again, Crow, to Slavicize the whole of Europe, but the Illyrians WERE NOT SLAVS, pure and simple!
They are distantly related to other Southern European tribes, the Thracians among them, none of whom are extant,
but, as their Magyar neighbors to the East, the Albanians pride themselves on being a non-Slavic ethnicity, sandwiched
in , so to speak, between myriad Slavic neighbors.
The Turks, for example, are a non-Semitic aka Middle Eastern peoples in origin, yet can evince substantive proof
of extreme admixture with Arab-speakers over the centuries:-)
Lyz, dobri prijatelju, go complaint to Israeli PM Netanyahu. He nicely explained which people is oldest in the region. Slavs, Serbs.
If you bother to have read up on the subject, ideally in your native language, you'd see that Albanians aka the descendants of Illyrians, are NOT of Slavic stock.
