Breakup of Yugoslavia: With the local Serb population boycotting the referendum, Croatians voted in favour of independence from Yugoslavia.

After a period of political and economic crisis in the 1980s, the constituent republics of the Socialist Federal Republic of Yugoslavia split apart in the early 1990s. Unresolved issues from the breakup caused a series of inter-ethnic Yugoslav Wars from 1991 to 2001 which primarily affected Bosnia and Herzegovina, neighbouring parts of Croatia and, some years later, Kosovo.

The Serbs of Croatia or Croatian Serbs constitute the largest national minority in Croatia. The community is predominantly Eastern Orthodox Christian by religion, as opposed to the Croats who are Catholic.

Croatia held an independence referendum on 19 May 1991, following the Croatian parliamentary elections of 1990 and the rise of ethnic tensions that led to the breakup of Yugoslavia. With 83 percent turnout, voters approved the referendum, with 93 percent in favor of independence. Subsequently, Croatia declared independence and the dissolution of its association with Yugoslavia on 25 June 1991, but it introduced a three-month moratorium on the decision when urged to do so by the European Community and the Conference on Security and Cooperation in Europe through the Brioni Agreement. The war in Croatia escalated during the moratorium, and on 8 October 1991, the Croatian Parliament severed all remaining ties with Yugoslavia. In 1992, the countries of the European Economic Community granted Croatia diplomatic recognition and Croatia was admitted to the United Nations.

The Socialist Federal Republic of Yugoslavia, known from 1945 to 1963 as the Federal People's Republic of Yugoslavia, commonly referred to as Socialist Yugoslavia or simply Yugoslavia, was a country in Central and Southeast Europe. It was established in 1945, following World War II, and lasted until 1992, dissolving amid the onset of the Yugoslav Wars. Spanning an area of 255,804 square kilometres (98,766 sq mi) in the Balkans, Yugoslavia was bordered by the Adriatic Sea and Italy to the west, Austria and Hungary to the north, Bulgaria and Romania to the east, and Albania and Greece to the south. It was a one-party socialist state and federation governed by the League of Communists of Yugoslavia, and had six constituent republics: Bosnia and Herzegovina, Croatia, Macedonia, Montenegro, Serbia, and Slovenia. Within Serbia was the Yugoslav capital city of Belgrade as well as two autonomous Yugoslav provinces: Kosovo and Vojvodina.
