During the Croatian-Serbian Civil War of the Balkan War, a federal Serb soldier was killed during an attack by Croatian soldiers on Vojnovic's barracks.

 　During the Croatian-Serbian Civil War of the Balkan War, an attack by Croatian soldiers on Vojnovic's barracks was successful. During that attack, a Serbian soldier in the federal army was killed. In 1992, after Croatia seceded from the Yugoslav Federation of Croatia, Slovenia, Macedonia, and Bosnia and Herzegovina, Serbian President Milosevic declared a new Yugoslav federation consisting of the two remaining states, Serbia and Montenegro. Yugoslav Federation, was proclaimed.

　The Croatian War of Independence was an armed conflict fought from 1991 to 1995 between Croatian forces loyal to the Croatian government, which declared independence from the Socialist Federal Republic of Yugoslavia (SFRY), and the Serb-dominated Yugoslav People's Army (JNA) and local Serb forces The JNA ended its combat operations in Croatia by 1992.

　Croatia held its first postwar multi-party elections in April 1990 amid democratic reforms in Eastern Europe at the end of the 1980s. The government of the Communist League was defeated, and the Croatian Democratic Union (HDZ), which has strong nationalist tendencies, won a landslide victory and took power. After the establishment of the new government, a new constitution with a strong nationalist character was adopted in December 1990, and the movement to secede from the Yugoslav federation accelerated; in May 1991, a referendum on independence resulted in 94% support for independence from the former Yugoslavia, and the parliament adopted a declaration of independence. Serbs boycotted the referendum. This led to fighting between Croatian and Serb forces, which culminated in a cease-fire agreement in January 1992 and the deployment of a UN Protection Force. Starting with European countries, other countries recognized Croatia as a state. In 1995, Croatia retook part of its territory from Serbian forces, and the remaining area of Eastern Slavonia (northeastern Croatia) was administered by the UN Interim Administration from 1996, With its withdrawal in January 1998, Croatia regained sovereignty over its entire territory.

　In Bosnia and Herzegovina, a major conflict erupted in April 1992 between Muslim, Croatian, and Serb populations over independence from the Socialist Federal Republic of Yugoslavia (former Yugoslavia). Each ethnic group fought for supremacy throughout Bosnia, resulting in 200,000 deaths and 2.2 million refugees and displaced persons, making it the worst conflict in postwar Europe. In December 1995, the fighting ended with the Dayton Peace Accords, and Bosnia became a single state consisting of two entities: the "Federation of Bosnia and Herzegovina" with Muslim and Croat residents, and the "Republika Srpska" with Serbian residents. The Office of the High Representative (OHR) and SFOR, a NATO-centered multinational force, were responsible for the civilian and military implementation of peace.
