By the time a tenuous peace is achieved in 1995, the country has been partitioned into three areas, with each region governed by one of the three ethnic groups. Each enclave is now made up of roughly 90% of its own ethnic group. April Serbia and Montenegro form the Federal Republic of Yugoslavia, with Slobodan Milosevic as its leader.
