I agree with Dab and Anthenaean Lontech accept this and stop exclaiming racist remarks If we accept this Dardanian kingdom which I accept is mentioned by historians it was  unstable  temporary and  lasted only during the reign of Bardyllis and his immedieate successors So to say that during Antiquity there was a Dardanian kingdom is wrong Antiquity is a period of one thousand years There was no kingdom for   years Moreoever your wording is nongrammatical To say Kosovo was the centre of Dardania is a nonsense statement Yu have to say something like the territory of presentday Kosovo roughly corresponds to the lands occupied by the Dardanii if you really have to mention them It is that simple Stop accusing people of nationalism and accept suggestions by people who have a more technical and less abrupt ie POV grasp of the English language
