One of the other main reasons is that Albanians have much higher birth rates than the Serbs.
Fertility Rates and Ethnic Resentment
Look how many times their national hero converted into different religions to understand how seriously Albanians take religion.
Milosevic treated the Kosovars same way Bulgarians treated their Pomaks and this never works .
I don't think there is any historical dispute between the two nations just idiotic politics that forced people to take sides . Balkanian nationalism is an artificial construct made for the purpose of creating nations out of the Ottoman soup .
Really.... sorry for my misunderstanding.
