What was the background in which the ethnic massacre took place in Kosovo?

(i) Kosovo was a province of Yugoslavia before it split. In this province, the Serbs were in minority and Albanians were in majority. while it was the other way round in the rest of the country.
(ii) A narrow-minded Serb nationalist Milosevic had won the elections. His government was hostile to the Kosovo Albanians.
(iii) He wanted the Serbs to dominate the country. Many Serb leaders thought that ethnic minorities like the Albanians should either leave the country or accept the dominance of the Serbs.
