[Banat]

History grad here.The fact that SOME third tribes (or even civilizations, such as the Romans) lived in "Serbia" prior to the arrival of the Serbian tribe(s) there obviously means that the Serbs aren't the first people to inhabit those lands. But, suffice it to say, no one's even disputing that.

However, they were there before the "Albanians," because the "Albanians" (a non-existant name at the time, obviously) represented a statistical error in Kosovo's population according to the Turkish census conducted some 8 centuries after the Serbian arrival. Actually, the population is almost exclusively Serb.

Furthermore, I was talking about the last 60 years when I said "illegal aliens." It was a well-known policy of the Communist rulers of Yugoslavia to have an open-door immigration policy toward Stalinist Albania. God knows who entered Serbia during those years. Conveniently enough, they created (the autonomous region of) Kosovo and kept expanding its jurisdictions and powers in order to further weaken Serbia. When the Minister of Interior of Serbia at the time started asking questions, he was promptly removed by Tito (1966).
