The Yugoslav Wars were a series of separate but related ethnic conflicts, wars of independence and insurgencies that took place from 1991 to 2001 in what had been the Socialist Federal Republic of Yugoslavia (SFR Yugoslavia). The conflicts both led up to and resulted from the breakup of Yugoslavia, which began in mid-1991, into six independent countries matching the six entities known as republics that had previously constituted Yugoslavia: Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, Serbia, and Macedonia (now called North Macedonia). SFR Yugoslavia's constituent republics declared independence due to rising nationalism. Unresolved tensions between ethnic minorities in the new countries led to the wars. While most of the conflicts ended through peace accords that involved full international recognition of new states, they resulted in a massive number of deaths as well as severe economic damage to the region.
During the initial stages of the breakup of Yugoslavia, the Yugoslav People's Army (JNA) sought to preserve the unity of the Yugoslav nation by eradicating all nationalists in the governments of the republics. However, it increasingly came under the influence of Slobodan Milošević, whose government invoked Serbian nationalism as an ideological replacement for the weakening communist system. As a result, the JNA began to lose Slovenes, Croats, Kosovar Albanians, Bosniaks, and Macedonians, and effectively became a fighting force of only Serbs and Montenegrins. According to a 1994 report by the United Nations (UN), the Serb side did not aim to restore Yugoslavia; instead, it aimed to create a "Greater Serbia" from parts of Croatia and Bosnia. Other irredentist movements have also been brought into connection with the Yugoslav Wars, such as "Greater Albania" (from Kosovo, idea abandoned following international diplomacy) and "Greater Croatia" (from parts of Herzegovina, abandoned in 1994 with the Washington Agreement).
