The war in Bosnia and Herzegovina came about as a result of the breakup of the Socialist Federal Republic of Yugoslavia. A crisis emerged in Yugoslavia as a result of the weakening of the confederational system at the end of the Cold War. In Yugoslavia, the national communist party, the League of Communists of Yugoslavia, was losing its ideological potency. Meanwhile, ethnic nationalism experienced a renaissance in the 1980s, after violence broke out in Kosovo. While the goal of Serbian nationalists was the centralisation of Yugoslavia, other nationalities in Yugoslavia aspired to the federalisation and the decentralisation of the state.
