Breakup of Yugoslavia The Breakup of Yugoslavia ( the Socialist Federal Republic of Yugoslavia , also known as " SFR Yugoslavia " or " SFRY " ) occurred as a result of a series of political upheavals and conflicts during the early 1990s . As a result of the Yugoslav Wars in the 1990s , the region that had been the SFR Yugoslavia split into several independent countries . The wars primarily affected Bosnia , Croatia and Serbia . Background . Yugoslavia occupied a strip of land on the east coast of the Adriatic Sea , stretching southward from the Bay of Trieste in Central Europe to the Gates of Otran , and eastward as far as the Carpathian Mountains , thus including a large part of Southeast Europe , a region with a history of ethnic conflict . The important elements that fostered the discord involved contemporary and historical factors , these included : the formation of the Kingdom of Yugoslavia , the first breakup and subsequent inter - ethnic and political wars and genocide during World War II , ideas of Greater Serbia , Greater Croatia , Greater Albania , and conflicting views about Pan - Slavism . Before World War II , major tensions arose from the first , monarchist Yugoslavia ' s multi - ethnic make - up and relative political and demographic domination of the Serbs . Fundamental to the tensions were the different concepts of the new state . The Croats and Slovenes envisaged a federal model where they would enjoy greater autonomy than they had as a separate crown land under Austria - Hungary . Under Austria - Hungary , both Slovenes and Croats enjoyed autonomy with free hands only in education , law , religion , and 45 % of taxes . The Serbs tended to view the territories as a just reward for their support of the allies in World War I and the new state as an extension of the Kingdom of Serbia . Tensions between the Croats and Serbs often erupted into open conflict , with the Serb - dominated security structure exercising oppression during elections and the assassination in federal parliament of Croat political leaders , including Stjepan Radić , who opposed the Serbian monarch ' s absolutism . The assassination and human rights abuses were subject of concern for the Human Rights League and precipitated voices of protest from intellectuals , including Albert Einstein . It was in this environment of oppression that the radical insurgent group ( later fascist dictatorship ) , the Ustaše were formed . During World War II , the country ' s tensions were exploited by the occupying Axis forces which established a Croat puppet state spanning much of present day Croatia and Bosnia and Herzegovina . The Axis powers installed the Ustaše as the leaders of the " Independent State of Croatia " . The Ustaše resolved that the Serbian minority were a fifth column of Serbian expansionism , and pursued a policy of persecution against the Serbs . The policy dictated that one - third of the Serbian minority were to be killed , one - third expelled , and one - third converted to Catholicism and assimilated as Croats . Conversely , the Chetniks pursued their own campaign of persecution in parts of Bosnia and Herzegovina and Sandžak per the Moljevic plan ( " On Our State and Its Borders " ) and the orders issues by Draža Mihailović which included " [ t ] he cleansing of all nation understandings and fighting " . Both Croats and Muslims were recruited as soldiers by the " SS " ( primarily in the 13th " Waffen " Mountain Division ) . At the same time , former royalist , General Milan Nedić , was installed by the Axis as head of the puppet government and local Serbs were recruited into the Gestapo and the Serbian Volunteer Corps . Both quisling s were confronted and eventually defeated by the communist - led , anti - fascist Partisan movement composed of members of all ethnic groups in the area , leading to the formation of the Socialist Federal Republic of Yugoslavia . The official Yugoslav post - war estimate of victims in Yugoslavia during World War II was 1 , 704 , 000 . Subsequent data gathering in the 1980s by historians Vladimir Žerjavić and Bogoljub Kočović showed that the actual number of dead was about 1 million . Of that number , 330 , 000 to 390 , 000 ethnic Serbs perished from all causes in Croatia and Bosnia . Yugoslavia was in its heyday a regional industrial power and an economic success . From 1960 to 1980 , annual gross domestic product ( GDP ) growth averaged 6 . 1 percent , medical care was free , literacy was 91 percent , and life expectancy was 72 years . Yugoslavia was a unique state , straddling both the East and West . Moreover its president , Josip Broz Tito , was one of the fundamental founders of the " third world " or " group of 77 " which acted as an alternative to the superpowers . More importantly , Yugoslavia acted as a buffer state between the West and the Soviet Union and also prevented the USSR from getting a toehold on the Mediterranean Sea . Tito ' s Yugoslavia was characterised by constant reforms which failed to resolve key national problems . Moreover , the federal system , due to increasing national tensions , and the Communist Party ' s wish to support " national self determination " began to loosen its control . This resulted Kosovo being turned into an autonomous region of Serbia , legislated by the 1974 constitution . This constitution broke down powers between the capital and the autonomous regions in Vojvodina ( an area of Yugoslavia with a large number of ethnic minorities ) and Kosovo ( with a large ethnic - Albanian population ) . Despite the federal structure of the new Yugoslavia , there was still tension between the federalists , primarily Croats and Slovenes who argued for greater autonomy , and unitarists , primarily Serbs . The struggle would occur in cycles of protests for greater individual and national rights ( such as the Croatian Spring ) and subsequent repression . The 1974 constitution was an attempt to short - circuit this pattern by entrenching the federal model and formalizing national rights . This loosened version of the federation essentially made Yugoslavia a de facto confederacy , placing pressure upon the legitimacy of the regime and engendering resentment in the richer republics . Slovenia and Croatia , the most developed republics were continually frustrated by their inability to further lift their standard of living as they had to subsidize the development of the poor republics in what they described as an " economic black hole " . It highlighted the vast differences in the quality of life in the different republics . The 1973 oil crisis coupled with Western trade barriers , dramatically hindered its thirty years of breakneck economic growth . In order to counter this , Yugoslavia took on a number of International Monetary Fund ( IMF ) loans and subsequently fell into heavy IMF debt . As a condition of receiving loans , the IMF demanded the " market liberalization " of Yugoslavia . By 1981 , Yugoslavia had incurred $ 19 . 9 billion in foreign debt . Another concern was the unemployment rate , at 1 million by 1980 . This problem was compounded by the general " unproductiveness of the South , " which not only added to Yugoslavia ’ s economic woes , but also irritated Slovenia and Croatia further . Causes . Structural problems . The SFR Yugoslavia was a conglomeration of eight federated entities , roughly divided along ethnic lines , including six republics — Slovenia , Croatia , Bosnia and Herzegovina , the Republic of Macedonia , Montenegro and Serbia — and two autonomous provinces within Serbia , Vojvodina and Kosovo . With the 1974 Constitution , the office of President of Yugoslavia was replaced with the Yugoslav Presidency , an eight - member collective head - of - state composed of representatives from six republics and , controversially , two autonomous provinces of the Socialist Republic of Serbia , SAP Kosovo and SAP Vojvodina . Since the SFR Yugoslav federation was formed in 1945 , the constituent Socialist Republic of Serbia ( SR Serbia ) included the two autonomous provinces of SAP Kosovo and SAP Vojvodina . With the 1974 constitution , the influence of the central government of SR Serbia over the provinces was greatly reduced , which gave them long - sought autonomy . The government of SR Serbia was restricted in making and carrying out decisions that would apply to the provinces . The provinces had a vote in the Yugoslav Presidency , which was not always cast in favor of SR Serbia . In Serbia , there was great resentment towards these developments , which the nationalist elements of the public saw as the " division of Serbia " . The 1974 constitution not only exacerbated Serbian fears of a " weak Serbia , for a strong Yugoslavia " but also hit at the heart of Serbian national sentiment . A majority of Serbs see Kosovo as the " cradle of the nation " , and would not accept the possibility of losing it to the majority Albanian population . In an effort to ensure his legacy , Tito ' s 1974 constitution established a system of year - long presidencies , on a rotation basis out of the eight leaders of the republics . Tito ' s death would show that such short terms were highly ineffective . Essentially it left a power vacuum which was left open for most of the 1980s . Economic collapse and the international climate . After the death of Tito with the rise of Mikhail Gorbachev , perestroika and glasnost in the Soviet Union , the West felt secure enough in the USSR ’ s intentions that Yugoslavia was no longer of pivotal strategic importance . Despite Belgrade ' s non - alignment and its extensive trading relations with the European Community and the US , the Reagan administration specifically targeted the Yugoslav economy in a Secret Sensitive 1984 National Security Decision Directive NSDD 133 . " U . S . Policy towards Yugoslavia . " A censored version declassified in 1990 elaborated on NSDD 54 on Eastern Europe , issued in 1982 . The latter advocated " expanded efforts to promote a ' quiet revolution ' to overthrow Communist governments and parties , " while reintegrating the countries of Eastern Europe into a market - oriented economy . The external status quo , which the Communist Party had depended upon to remain viable was thus beginning to disappear . Furthermore , the failure of communism all over Central and Eastern Europe once again brought Yugoslavia ’ s inner contradictions , economic inefficiencies ( such as chronic lack of productivity , fuelled by the country ' s leaderships ' decision to enforce a policy of full employment ) , and ethno - religious tensions to the surface . Yugoslavia ' s non - aligned status resulted in access to loans from both superpower blocs . This contact with the United States and the West opened up Yugoslavia ’ s markets sooner than the rest of Central and Eastern Europe . The 1980s were a decade of Western economic ministrations . A decade of frugality resulted in growing frustration and resentment against both the Serbian ' ruling class , ' and the minorities who were seen to benefit from government legislation . Real earnings in Yugoslavia fell by 25 % from 1979 to 1985 . By 1988 emigrant remittances to Yugoslavia totalled over $ 4 . 5 billion ( USD ) , and by 1989 remittances were $ 6 . 2 billion ( USD ) , making up over 19 % of the world ' s total . Death of Tito and the weakening of Communism . After the death of President Josip Broz Tito on 4 May 1980 , ethnic tension grew in Yugoslavia . The death of Tito removed what many Yugoslavs and western observers saw as the country ' s main unifying force . The crisis that emerged in Yugoslavia was connected with the weakening of the Communist states in Eastern Europe towards the end of the Cold War , as symbolized by the fall of the Berlin Wall in 1989 . In Yugoslavia , the national communist party , officially called the League of Communists of Yugoslavia , had lost its ideological potency . In 1986 , the Serbian Academy of Sciences and Arts ( SANU ) contributed significantly to the rise of nationalist sentiments , as it drafted the controversial SANU Memorandum protesting against the weakening of the Serbian central government . The problems in the Serbian autonomous province of SAP Kosovo between ethnic Serbs and Albanians grew exponentially . This , coupled with economic problems in Kosovo and Serbia as a whole , led to even greater Serbian resentment of the 1974 Constitution . In the 1980s , Kosovo Albanians started to demand that their autonomous province be granted the status of a constituent republic , starting with the 1981 protests in Kosovo . Amid rising tensions , the Serbian general view was that Kosovo as a constituent republic ( as opposed to being part of Serbia ) would be devastating to the cultural and historic links with Kosovar Serbs and Kosovo in general , especially if they were to choose to secede . In the 1980s , this led to the repression of the Albanian majority in Serbia ' s southern province . The more prosperous republics of SR Slovenia and SR Croatia wanted to move towards decentralization and democracy . Rise of nationalism in SR Serbia ( 1987 – 89 ) . Slobodan Milošević . In 1987 , Serbian communist official Slobodan Milošević was sent to bring calm to an ethnically - driven protest by Serbs against the Albanian administration of SAP Kosovo . Milošević had been , up to this point , a hard - line communist who had decried all forms of nationalism as treachery , such as condemning the SANU Memorandum as " nothing else but the darkest nationalism " . However , Kosovo ' s autonomy had always been an unpopular policy in Serbia and he took advantage of the situation and made a departure from traditional communist neutrality on the issue of Kosovo . Milošević assured Serbs that their mistreatment by ethnic Albanians would be stopped . He then began a campaign against the ruling communist elite of SR Serbia , demanding reductions in the autonomy of Kosovo and Vojvodina . These actions made him popular amongst Serbs and aided his rise to power in Serbia . Milošević and his allies took on an aggressive nationalist agenda of reviving SR Serbia within Yugoslavia , promising reforms and protection of all Serbs . The ruling party of SFR Yugoslavia was the League of Communists of Yugoslavia ( SKJ ) , a composite political party made - up of eight Leagues of Communists from the six republics and two autonomous provinces . The League of Communists of Serbia ( SKS ) governed SR Serbia . Riding the wave of nationalist sentiment and his new popularity gained in Kosovo , Slobodan Milošević ( Chairman of the League of Communists of Serbia ( SKS ) since May 1986 ) became the most powerful politician in Serbia by defeating his former mentor President of Serbia Ivan Stambolic at the 8th Session of the League of Communists of Serbia on 22 September 1987 . In a 1988 Belgrade rally , Milošević made clear his perception of the situation facing SR Serbia in Yugoslavia , saying : " At home and abroad , Serbia ' s enemies are massing against us . We say to them ' We are not afraid ' . ' We will not flinch from battle ' . " Slobodan Milošević , 19 November 1988 . On another occasion , he privately stated : " " We Serbs will act in the interest of Serbia whether we do it in compliance with the constitution or not , whether we do it in compliance in the law or not , whether we do it in compliance with party statutes or not . " " Slobodan Milošević Anti - bureaucratic revolution . The Anti - bureaucratic revolution was a series of revolts in Serbia and Montenegro which brought Milošević ' s supporters in SAP Vojvodina , SAP Kosovo , and the Socialist Republic of Montenegro ( SR Montenegro ) to power . The government of Montenegro survived a coup d ' état in October 1988 , but not a second one in January 1989 . In addition to Serbia itself , Milošević could now install representatives of the two provinces and SR Montenegro in the Yugoslav Presidency Council . The very instrument that reduced Serbian influence before was now used to increase it : in the eight member Presidency , Milošević could count on a minimum of four votes – SR Montenegro ( following local events ) , his own through SR Serbia , and now SAP Vojvodina and SAP Kosovo as well . In a series of rallies , called " Rallies of Truth " , Milošević ' s supporters succeeded in overthrowing local governments and replacing them with his allies . As a result of these events , in February 1989 the ethnic Albanian miners in Kosovo organized the 1989 Kosovo miners ' strike , demanding the reinstatement of their autonomy . This contributed to ethnic conflict between the Albanians and the Serb population of the province . At 77 % of the population of Kosovo in the 1980s , ethnic - Albanians were the majority . In June 1989 , the 600th anniversary of Serbia ’ s historic defeat at the field of Kosovo , Slobodan Milošević gave the Gazimestan speech to 200 , 000 Serbs , with a Serb nationalist theme which deliberately evoked medieval Serbian history . Milošević ’ s answer to the incompetence of the federal system was to centralise the government . Considering Slovenia and Croatia were looking farther ahead to independence , this was considered unacceptable . Repercussions . Meanwhile the Socialist Republic of Croatia ( SR Croatia ) and the Socialist Republic of Slovenia ( SR Slovenia ) , supported the Albanian miners and their struggle for recognition . Media in SR Slovenia published articles comparing Milošević to Italian fascist dictator Benito Mussolini . Milošević contended that such criticism was unfounded and amounted to " spreading fear of Serbia " . Milošević ' s state - run media claimed in response that Milan Kučan , head of the League of Communists of Slovenia , was endorsing Kosovo and Slovene separatism . Initial strikes in Kosovo turned into widespread demonstrations calling for Kosovo to be made the seventh republic . This angered Serbia ' s leadership which proceeded to use police force , and later the federal army ( the Yugoslav People ' s Army JNA ) by order of the Serbian - controlled Presidency . In February 1989 ethnic Albanian Azem Vllasi , SAP Kosovo ' s representative on the Presidency , was forced to resign and was replaced by an ally of Milošević . Albanian protesters demanded that Vllasi be returned to office , and Vllasi ' s support for the demonstrations caused Milošević and his allies to respond stating this was a " counter - revolution against Serbia and Yugoslavia " , and demanded that the federal Yugoslav government put down the striking Albanians by force . Milošević ' s aim was aided when a huge protest was formed outside of the Yugoslav parliament in Belgrade by Serb supporters of Milošević who demanded that the Yugoslav military forces enter Kosovo to protect the Serbs there and put down the strike . On 27 February , SR Slovene representative in the collective presidency of Yugoslavia , Milan Kučan , opposed the demands of the Serbs and left Belgrade for SR Slovenia where he attended a meeting in the Cankar Hall in Ljubljana , co - organized with the democratic opposition forces , publicly endorsing the efforts of Albanian protesters who demanded that Vllasi be released . In the 1995 BBC documentary " Death of Yugoslavia " , Kučan claimed that in 1989 , he was concerned that with the successes of Milošević ' s anti - bureaucratic revolution in Serbia ' s provinces as well as Montenegro , that his small republic would be the next target for a political coup by Milošević ' s supporters if the coup in Kosovo went unimpeded . Serbian state - run television denounced Kučan as a separatist , a traitor , and an endorser of Albanian separatism . Serb protests continued in Belgrade demanding action in Kosovo . Milošević instructed communist representative Petar Gračanin to make sure the protest continued while he discussed matters at the council of the League of Communists , as a means to induce the other members to realize that enormous support was on his side in putting down the Albanian strike in Kosovo . Serbian parliament speaker Borisav Jović , a strong ally of Milošević , met with the current President of the Yugoslav Presidency , Bosnian representative Raif Dizdarević , and demanded that the federal government concede to Serbian demands . Dizdarević argued with Jović saying that " You [ Serbian politicians ] organized the demonstrations , you control it " , Jović refused to take responsibility for the actions of the protesters . Dizdarević then decided to attempt to bring calm to the situation himself by talking with the protesters , by making an impassioned speech for unity of Yugoslavia saying : " Our fathers died to create Yugoslavia . We will not go down the road to national conflict . We will take the path of Brotherhood and Unity . " Raif Dizdarević , 1989 . This statement received polite applause , but the protest continued . Later Jović spoke to the crowds with enthusiasm and told them that Milošević was going to arrive to support their protest . When Milošević arrived , he spoke to the protesters and jubilantly told them that the people of Serbia were winning their fight against the old party bureaucrats . Then a shout to be from the crowd yelled " arrest Vllasi ' " . Milošević pretended not to hear the demand correctly but declared to the crowd that anyone conspiring against the unity of Yugoslavia would be arrested and punished and the next day , with the party council pushed to submission to Serbia , Yugoslav army forces poured into Kosovo and Vllasi was arrested . In March 1989 , the crisis in Yugoslavia deepened after the adoption of amendments to the Serbian constitution that allowed the Serbian republic ' s government to re - assert effective power over the autonomous provinces of Kosovo and Vojvodina . Up until that time , a number of political decisions were legislated from within these provinces , and they had a vote on the Yugoslav federal presidency level ( six members from the republics and two members from the autonomous provinces ) . A group of Kosovo Serb supporters of Milošević who helped bring down Vllasi declared that they were going to Slovenia to hold " the Rally of Truth " which would decry Milan Kučan as a traitor to Yugoslavia and demand his ousting . However , the attempt to replay the anti - bureaucratic revolution in Ljubljana in December 1989 failed : the Serb protesters who were to go by train to Slovenia , were stopped when the police of SR Croatia blocked all transit through its territory in coordination with the Slovene police forces . In the Presidency of Yugoslavia , Serbia ' s Borisav Jović ( at the time the President of the Presidency ) , Montenegro ' s Nenad Bućin , Vojvodina ' s Jugoslav Kostić and Kosovo ' s Riza Sapunxhiu , started to form a voting bloc . Final political crisis ( 1990 – 92 ) . Party crisis . In January 1990 , the extraordinary 14th Congress of the League of Communists of Yugoslavia was convened . The combined Yugoslav ruling party , the League of Communists of Yugoslavia ( SKJ ) , was in crisis . Most of the Congress was spent with the Serbian and Slovene delegations arguing over the future of the League of Communists and Yugoslavia . SR Croatia ' s actions in preventing Serb protesters from reaching Slovenia played its part . The Serbian delegation , led by Milošević , insisted on a policy of " one person , one vote " in the party membership , which would empower the largest party ethnic group , the Serbs . In turn , the Croats and Slovenes sought to reform Yugoslavia by delegating even more power to six republics , but were voted down continuously in every motion in an attempt to force the party to adopt the new voting system . As a result , the Croatian delegation , led by Chairman Ivica Račan , and Slovene delegation left the Congress on 23 January 1990 , effectively dissolving the all - Yugoslav party . This in turn , along with external pressure , caused the adoption of multi - party systems in all republics . Multi - party elections . When the individual republics organized their multi - party elections in 1990 , the ex - communists mostly failed to win re - election , while most of the elected governments took on nationalist platforms , promising to protect their separate nationalist interests . In multi - party parliamentary elections nationalists defeated re - branded former Communist parties in Slovenia on 8 April 1990 , in Croatia on 22 April and 2 May 1990 , in Macedonia 11 and 25 November and 9 December 1990 , and in Bosnia and Herzegovina on 18 and 25 November 1990 . In multi - party parliamentary elections , re - branded former communist parties were victorious in Montenegro on 9 and 16 December 1990 , and in Serbia on 9 and 23 December 1990 . In addition Serbia re - elected Slobodan Milošević as President . Serbia and Montenegro now increasingly favored a Serb - dominated Yugoslavia . Ethnic tensions in Croatia . In Croatia , the nationalist Croatian Democratic Union ( HDZ ) was elected to power , led by controversial nationalist Franjo Tuđman , under the promise of " protecting Croatia from Milošević " . There was growing advocacy for " Croatian state and historical rights " which resulted in the status of ethnic Serbs of Croatia being changed from " constitutional nation " to " national minority " . Croatian Serbs , for their part , were wary of Tuđman ' s nationalist government and in 1990 , Serb nationalists in the southern Croatian town of Knin organized and formed a separatist entity known as the SAO Krajina , which demanded to remain in union with the rest of the Serb populations if Croatia decided to secede . The government of Serbia endorsed the Croatian Serbs ' rebellion , claiming that for Serbs , rule under Tuđman ' s government would be equivalent to the World War II fascist Independent State of Croatia ( NDH ) which committed genocide against Serbs during World War II . Milošević used this to rally Serbs against the Croatian government and Serbian newspapers joined in the warmongering . Serbia had by now printed $ 1 . 8 billion worth of new money without any backing of Yugoslav central bank . Croatian Serbs in Knin , under the leadership of local Knin police inspector Milan Martić , began to try to gain access to weapons so that the Croatian Serbs could mount a successful revolt against the Croatian government . Croatian Serb politicians including the Mayor of Knin met with Borisav Jović , the head of the Yugoslav Presidency in August 1990 , and urged him to push the council to take action to prevent Croatia from separating from Yugoslavia , as they claimed that the Serb population would be in danger in Croatia led by Tuđman and his nationalist government . At the meeting , army official Petar Gračanin told the Croatian Serb politicians how to organize their rebellion , telling them to put up barricades , as well as assemble weapons of any sort in which he said " If you can ' t get anything else , use hunting rifles " . Initially the revolt became known as the " Log Revolution " as Serbs blockaded roadways to Knin with cut - down trees and prevented Croats from entering Knin or the Croatian coastal region of Dalmatia . The BBC documentary " Death of Yugoslavia " revealed that at the time , Croatian TV dismissed the " Log Revolution " as the work of drunken Serbs , trying to diminish the serious dispute . However the blockade was damaging to Croatian tourism . The Croatian government refused to negotiate with the Serb separatists and decided to stop the rebellion by force , and sent in armed special forces by helicopters to put down the rebellion . The pilots claimed they were bringing " equipment " to Knin , but the federal Yugoslav Air Force intervened and sent fighter jets to intercept them and demanded that the helicopters return to their base or they would be fired upon , in which the Croatian forces obliged and returned to their base in Zagreb . To the Croatian government , this action by the Yugoslav Air Force revealed to them that the Yugoslav People ' s Army was increasingly under Serbian control . The SAO Krajina was officially declared as a separate entity on 21 December 1990 , by the Serbian National Council headed by Milan Babić . In August 1990 the Croatian Parliament replaced its representative Stipe Šuvar with Stjepan Mesić in the wake of the Log Revolution . Mesić was only seated in October 1990 because of protests from the Serbian side , and then joined Macedonia ' s Vasil Tupurkovski , Slovenia ' s Janez Drnovšek and Bosnia and Herzegovina ' s Bogić Bogićević in opposing the demands to proclaim a general state of emergency , which would have allowed the Yugoslav People ' s Army to impose martial law . Following the first multi - party election results , the republics of Slovenia , Croatia and Macedonia proposed transforming Yugoslavia into a loose federation of six republics in the autumn of 1990 , however Milošević rejected all such proposals , arguing that like Slovenians and Croats , the Serbs also had a right to self - determination . Independence of Slovenia and Croatia . In the Slovenian independence referendum , 1990 , held on 23 December 1990 , a vast majority of residents voted for independence . 88 . 5 % of all electors ( 94 . 8 % of those participating ) voted for independence – which was declared on 25 June 1991 . In January 1991 , the KOS ( " Kontraobaveštajna služba " , Yugoslav counter - intelligence service ) displayed a video of a secret meeting ( the " Špegelj Tapes " ) that they purported had happened some time in 1990 between the Croatian Defence Minister , Martin Špegelj , and two other men , in which Špegelj announced that they were at war with the army and gave instructions about arms smuggling as well as methods of dealing with the Yugoslav Army ' s officers stationed in Croatian cities . The Army subsequently wanted to indict Špegelj for treason and illegal importation of arms , mainly from Hungary . The discovery of Croatian arms smuggling combined with the crisis in Knin , the election of independence - leaning governments in Bosnia & Herzegovina , Croatia , Macedonia and Slovenia , and Slovenes demanding independence in the referendum on the issue suggested that Yugoslavia faced the imminent threat of disintegration . On 1 March 1991 , the Pakrac clash ensued , and the Yugoslav People ' s Army ( " Jugoslovenska Narodna Armija , JNA " ) was deployed to the scene . On 9 March 1991 , the March 1991 protests in Belgrade were suppressed with the help of the Army . On 12 March 1991 , the leadership of the Army met with the Presidency in an attempt to convince them to declare a state of emergency which would allow for the pan - Yugoslav army to take control of the country . Yugoslav army chief Veljko Kadijević declared that there was a conspiracy to destroy the country , saying : " An insidious plan has been drawn up to destroy Yugoslavia . Stage one is civil war . Stage two is foreign intervention . Then puppet regimes will be set up throughout Yugoslavia . " Veljko Kadijević , 12 March 1991 . This statement effectively implied that the new independence - advocating governments of the republics were seen by Serbs as tools of the West . Croatian delegate Stjepan Mesić responded angrily to the proposal , accusing Jović and Kadijević of attempting to use the army to create a Greater Serbia and declared " That means war ! " . Jović and Kadijević then called upon the delegates of each republic to vote on whether to allow martial law , and warned them that Yugoslavia would likely fall apart if martial law was not introduced . In the meeting , a vote was taken on a proposal to enact martial law to allow for military action to end the crisis in Croatia by providing protection for the Serbs . The proposal was rejected by one vote , as the Bosnian Serb delegate , Bogić Bogićević , voted against it , believing that there was still the possibility of diplomacy being able to solve the crisis . The Yugoslav Presidency crisis reached an impasse in when Sapunxhiu ' defected ' his faction in the second vote on martial law in March 1991 . Jović briefly resigned from the presidency in protest , but soon returned . On 16 May 1991 , the Serbian parliament replaced Kosovo ' s Riza Sapunxhiu with Sejdo Bajramović , and Vojvodina ' s Nenad Bućin with Jugoslav Kostić . This effectively deadlocked the Presidency , because Milošević ' s Serbian faction had secured four out of eight federal presidency votes and it was able to block any unfavorable decisions at the federal level , in turn causing objections from other republics and calls for reform of the Yugoslav Federation . After Jović ' s term as head of the collective presidency expired , he blocked his successor , Mesić , from taking the position , and giving the position instead to Branko Kostić , a member of the pro - Milošević government in Montenegro . In the Croatian independence referendum held on 2 May 1991 , 93 . 24 % voted for independence . On 19 May 1991 , the second round of the referendum on the structure of the Yugoslav federation was held in Croatia . The phrasing of the question did not explicitly inquire as to whether one was in favor of secession or not . The referendum asked the voter if he or she was in favor of Croatia being " able to enter into an alliance of sovereign states with other republics ( in accordance with the proposal of the republics of Croatia and Slovenia for solving the state crisis in the SFRY ) ? " . 83 . 56 % of the voters turned out , with Croatian Serbs largely boycotting the referendum . Of these , 94 . 17 % ( 78 . 69 % of the total voting population ) voted " in favor " of the proposal , while 1 . 2 % of those who voted were " opposed " . Finally , the independence of Croatia was declared on 25 June 1991 . The beginning of the Yugoslav Wars . War in Slovenia . Both Slovenia and Croatia declared their independence on 25 June 1991 . On the morning of 26 June , units of the Yugoslav People ' s Army ' s 13th Corps left their barracks in Rijeka , Croatia , to move towards Slovenia ' s borders with Italy . The move immediately led to a strong reaction from local Slovenians , who organized spontaneous barricades and demonstrations against the YPA ' s actions . There was , as yet , no fighting , and both sides appeared to have an unofficial policy of not being the first to open fire . By this time , the Slovenian government had already put into action its plan to seize control of both the international Ljubljana Airport and the Slovenia ' s border posts on borders with Italy , Austria and Hungary . The personnel manning the border posts were , in most cases , already Slovenians , so the Slovenian take - over mostly simply amounted to changing of uniforms and insignia , without any fighting . By taking control of the borders , the Slovenians were able to establish defensive positions against an expected YPA attack . This meant that the YPA would have to fire the first shot . It was fired on 27 June at 14 : 30 in Divača by an officer of YPA . On 7 July 1991 , whilst supportive of their respective rights to national self - determination , the European Community pressured Slovenia and Croatia to place a three - month moratorium on their independence with the Brijuni Agreement ( recognized by representatives of all republics ) . During these three months , the Yugoslav Army completed its pull - out from Slovenia . Negotiations to restore the Yugoslav federation with diplomat Lord Peter Carington and members of the European Community were all but ended . Carington ' s plan realized that Yugoslavia was in a state of dissolution and decided that each republic must accept the inevitable independence of the others , along with a promise to Serbian President Milošević that the European Union would insure that Serbs outside of Serbia would be protected . Milošević refused to agree to the plan , as he claimed that the European Community had no right to dissolve Yugoslavia and that the plan was not in the interests of Serbs as it would divide the Serb people into four republics ( Serbia , Montenegro , Bosnia & Herzegovina , and Croatia ) . Carington responded by putting the issue to a vote in which all the other republics , including Montenegro under Momir Bulatović , initially agreed to the plan that would dissolve Yugoslavia . However , after intense pressure from Serbia on Montenegro ' s President , Montenegro changed its position to oppose the dissolution of Yugoslavia . War in Croatia . With the Plitvice Lakes incident of late March / early April 1991 , the Croatian War of Independence broke out between the Croatian government and the rebel ethnic Serbs of the SAO Krajina ( heavily backed by the by - now Serb - controlled Yugoslav People ' s Army ) . On 1 April 1991 , the SAO Krajina declared that it would secede from Croatia . Immediately after Croatia ' s declaration of independence , Croatian Serbs also formed the SAO Western Slavonia and the SAO of Eastern Slavonia , Baranja and Western Srijem . These three regions would combine into the Republic of Serbian Krajina ( RSK ) on 19 December 1991 . The other significant Serb - dominated entities in eastern Croatia announced that they too would join SAO Krajina . Zagreb had by this time discontinued submitting tax money to Belgrade , and the Croatian Serb entities in turn halted paying taxes to Zagreb . In some places , the Yugoslav Army acted as a buffer zone , in others it aided Serbs in their confrontation with the new Croatian army and police forces . The influence of xenophobia and ethnic hatred in the collapse of Yugoslavia became clear during the war in Croatia . Propaganda by Croatian and Serbian sides spread fear , claiming that the other side would engage in oppression against them and would exaggerate death tolls to increase support from their populations . In the beginning months of the war , the Serb - dominated Yugoslav army and navy deliberately shelled civilian areas of Split and Dubrovnik , a UNESCO world heritage site , as well as nearby Croat villages . Yugoslav media claimed that the actions were done due to what they claimed was a presence of fascist Ustaše forces and international terrorists in the city . UN investigations found that no such forces were in Dubrovnik at the time . Croatian military presence increased later on . Montenegrin Prime Minister Milo Đukanović , at the time an ally of Milošević , appealed to Montenegrin nationalism , promising that the capture of Dubrovnik would allow the expansion of Montenegro into the city which he claimed was historically part of Montenegro , and denounced the present borders of Montenegro as being " drawn by the old and poorly educated Bolshevik cartographers " . At the same time , the Serbian government contradicted its Montenegrin allies by claims by the Serbian Prime Minister Dragutin Zelenović contended that Dubrovnik was historically Serbian , not Montenegrin . The international media gave immense attention to bombardment of Dubrovnik and claimed this was evidence of Milosevic pursuing the creation of a Greater Serbia as Yugoslavia collapsed , presumably with the aid of the subordinate Montenegrin leadership of Bulatović and Serb nationalists in Montenegro to foster Montenegrin support for the retaking of Dubrovnik . In Vukovar , ethnic tensions between Croats and Serbs exploded into violence when the Yugoslav army entered the town . The Yugoslav army and Serbian paramilitaries devastated the town in urban warfare and the destruction of Croatian property . Serb paramilitaries committed atrocities against Croats , killing over 200 , and displacing others to add to those who fled the town in the Vukovar massacre . Independence of the Republic of Macedonia and Bosnia and Herzegovina . Bosnia and Herzegovina . With Bosnia ' s demographic structure comprising a mixed population of a majority of Bosniaks , Serbs and a minority of Croats , the ownership of large areas of Bosnia was in dispute . From 1991 to 1992 , the situation in the multiethnic Bosnia and Herzegovina grew tense . Its parliament was fragmented on ethnic lines into a majority Bosniak faction and minority Serb and Croat factions . In 1991 , the controversial nationalist leader Radovan Karadžić of the largest Serb faction in the parliament , the Serb Democratic Party gave a grave and direct warning to Bosnia ' s Bosniak president on the fate of Bosnia and its Bosniaks should it decide to separate , saying : " This , what you are doing , is not good . This is the path that you want to take Bosnia and Herzegovina on , the same highway of hell and death that Slovenia and Croatia went on . Don ' t think that you won ' t take Bosnia and Herzegovina into hell , and the Muslim people maybe into extinction . Because the Muslim people cannot defend themselves if there is war here . " Radovan Karadžić , 14 October 1991 . In the meantime , behind the scenes negotiations began between Milošević and Tuđman to divide Bosnia and Herzegovina into Serb and Croat administered territories to attempt to avert war between Bosnian Croats and Serbs . While , in Bosnia and Herzegovina , Bosnian Serbs held the November 1991 referendum which resulted in an overwhelming vote in favor of staying in a common state with Serbia and Montenegro . In public , pro - state media in Serbia claimed to Bosnians that Bosnia and Herzegovina could be included a new voluntary union within a new Yugoslavia based on democratic government , but this was not taken seriously by Bosnia and Herzegovina ' s government . On 9 January 1992 , the Bosnian Serb assembly proclaimed a separate Republic of the Serb people of Bosnia and Herzegovina ( the soon - to - be Republic of Srpska ) , and proceeded to form Serbian autonomous regions ( SARs ) throughout the state . The Serbian referendum on remaining in Yugoslavia and the creation of Serbian autonomous regions ( SARs ) were proclaimed unconstitutional by the government of Bosnia and Herzegovina . In February – March 1992 , the government itself held a national referendum on Bosnian independence from Yugoslavia . In the Bosnia and Herzegovina independence referendum , 1992 , held on 29 February and 1 March 1992 , 92 . 7 % voted for independence . That referendum was in turn declared contrary to the BiH and Federal constitution by the federal Constitution court and the newly established Bosnian Serb government ; it was also largely boycotted by the Bosnian Serbs . The turnout was somewhere between 64 – 67 % and 98 % of the voters voted for independence . It was unclear what the two - thirds majority requirement actually meant and whether it was satisfied . The republic ' s government declared its independence on 3 March and then on 5 April , and the Serbs immediately declared the independence of Republika Srpska . The Bosnian War followed shortly thereafter . Republic of Macedonia . In the Macedonian independence referendum held on 8 September 1991 , 95 . 26 % voted for independence . It was declared on 25 September 1991 . Five hundred US soldiers were then deployed under the UN banner to monitor Macedonia ' s northern borders with the Republic of Serbia , Yugoslavia . However , given that Belgrade ' s authorities had neither intervened to prevent Macedonia ' s departure , nor protested nor acted against the arrival of the UN troops , the indications were in place that once Belgrade was to form its new country ( to be the Federal Republic of Yugoslavia from April 1992 ) , it would recognise the Republic of Macedonia and develop diplomatic relations with it . As such , it became the only former republic to gain sovereignty without resistance from the Belgrade - based Yugoslav authorities and Army . In addition , Macedonia ' s first president , Kiro Gligorov , did indeed maintain good relations with Belgrade as well as the other former republics and there have to date been no problems between Macedonian and Serbian border police despite the fact that small pockets of Kosovo and the Preševo valley complete the northern reaches of the historical region known as Macedonia , which would otherwise have created a border dispute ( see also IMORO ) . The Insurgency in the Republic of Macedonia , the last major conflict being between Albanian nationalists and the government of Republic of Macedonia , reduced in violence after 2001 . International recognition of the breakup . In November 1991 , the Arbitration Commission of the Peace Conference on Yugoslavia , led by Robert Badinter , concluded at the request of Lord Carrington that the SFR Yugoslavia was in the process of dissolution , that the Serbian population in Croatia and Bosnia does not have a right to self - determination in form of new states , and that the borders between the republics are to be recognized as international borders . As a result of the conflict , the United Nations Security Council unanimously adopted UN Security Council Resolution 721 on 27 November 1991 , which paved the way to the establishment of peacekeeping operations in Yugoslavia . In January 1992 , Croatia and Yugoslavia signed an armistice under UN supervision , while Negotiations continued between Serb and Croat leaderships over the partitioning of Bosnia and Herzegovina . On 15 January 1992 , the independence of Croatia and Slovenia was recognized worldwide . Slovenia , Croatia , and Bosnia would later be admitted as member states of the United Nations on 22 May 1992 . Macedonia was admitted as a member state of the United Nations on 8 April 1993 . Aftermath in Serbia and Montenegro . The independence of Bosnia and Herzegovina proved to be the final blow to the pan - Yugoslav Socialist Federal Republic of Yugoslavia . On 28 April 1992 , the Serb - dominated Federal Republic of Yugoslavia ( FRY ) was formed as a rump state , consisting only of the former Socialist Republics of Serbia and Montenegro . Its government claimed continuity to the former country , however , the international community refused to recognize it as such . The stance of the international community was that Yugoslavia had dissolved into its separate states . The Federal Republic of Yugoslavia was prevented by a UN resolution on 22 September 1992 from continuing to occupy the United Nations seat as successor state to SFRY . This question was important for claims on SFRY ' s international assets , including embassies in many countries . Only in 1996 had the FRY abandoned its claim to continuity from the SFRY . The FRY was dominated by Slobodan Milošević and his political allies . The five years of disintegration and war in the 1990s led to a boycott and embargo of the Federal Republic of Yugoslavia , whose economy collapsed as a result . The war in the western parts of former Yugoslavia ended in 1995 with US - sponsored peace talks in Dayton , Ohio , which resulted in the Dayton Agreement . The Kosovo War started in 1996 and ended with the 1999 NATO bombing of Yugoslavia ; NATO had intervened to prevent widespread human rights abuses by Serb forces . Slobodan Milošević was overthrown in 2000 . FR Yugoslavia was renamed on 4 February 2003 as the State Union of Serbia and Montenegro . The State Union of Serbia and Montenegro was itself unstable , and finally broke up during 2006 to 2008 . In a referendum held in Montenegro on 21 May 2006 independence was backed by 55 . 5 % of voters , and independence was declared on 3 June 2006 . Serbia inherited the State Union ' s UN membership . Kosovo had been administered by the UN since the Kosovo war ; it declared independence on 17 February 2008 . This is not recognized by Serbia , and has limited recognition across the international community .
