The Milosevic government in Serbia was hostile to the Kosovo Albanians primarily because they wanted Serbs to dominate the country. This hostility was fueled by a combination of historical, political, and ethnic factors.

1. Historical Factors:
- Kosovo holds immense historical and cultural significance for the Serbs. It is considered the birthplace of the Serbian nation and holds many important religious sites for the Serbian Orthodox Church.
- The Battle of Kosovo in 1389 between the Serbs and the Ottoman Empire is often seen as a defining moment in Serbian history. The memory of this battle and the subsequent centuries of Ottoman rule created a deep sense of victimhood and resentment among the Serbs.
- During the breakup of Yugoslavia in the 1990s, Kosovo was seen by many Serbs as the "cradle of Serbian civilization" that must remain under Serbian control.

2. Political Factors:
- Slobodan Milosevic, the President of Serbia at the time, employed a nationalist agenda to consolidate his power. He used the Kosovo issue to rally Serbs behind his leadership and promote a sense of Serbian nationalism.
- Milosevic's government aimed to maintain control over all regions of Yugoslavia, including Kosovo, to create a Greater Serbia. This policy involved suppressing the rights and autonomy of the Albanian majority in Kosovo.

3. Ethnic Factors:
- Kosovo has a significant ethnic Albanian population, with Albanians constituting the majority in the region. The Albanians have their own distinct language, culture, and historical ties to the territory.
- The Serbian government, driven by a desire to maintain Serbian dominance, viewed the ethnic Albanians as a threat to their control over Kosovo. The Albanians were seen as outsiders who needed to be marginalized and suppressed.

In summary, the Milosevic government's hostility towards the Kosovo Albanians was driven by a desire to establish Serbian dominance over the region. Historical, political, and ethnic factors all played a role in shaping this hostile attitude.
