In the aftermath of the Second World War, the Balkan states of Bosnia-Herzegovina, Serbia, Montenegro, Croatia, Slovenia and Macedonia became part of the Federal People's Republic of Yugoslavia. After the death of longtime Yugoslav leader Josip Broz Tito in 1980, growing nationalism among the different Yugoslav republics threatened to split their union apart. This process intensified after the mid-1980s with the rise of the Serbian leader Slobodan Milosevic, who helped foment discontent between Serbians in Bosnia and Croatia and their Croatian, Bosniak and Albanian neighbors. In 1991, Slovenia, Croatia and Macedonia declared their independence; during the war in Croatia that followed, the Serb-dominated Yugoslav army supported Serbian separatists there in their brutal clashes with Croatian forces.
In Bosnia, Muslims represented the largest single population group by 1971. More Serbs and Croats emigrated over the next two decades, and in a 1991 census Bosnia's population of some 4 million was 44 percent Bosniak, 31 percent Serb, and 17 percent Croatian. Elections held in late 1990 resulted in a coalition government split between parties representing the three ethnicities (in rough proportion to their populations) and led by the Bosniak Alija Izetbegovic. As tensions built inside and outside the country, the Bosnian Serb leader Radovan Karadzic and his Serbian Democratic Party withdrew from government and set up their own “Serbian National Assembly.” On March 3, 1992, after a referendum vote (which Karadzic's party blocked in many Serb-populated areas), President Izetbegovic proclaimed Bosnia's independence.
Struggle for Control in Bosnia
Far from seeking independence for Bosnia, Bosnian Serbs wanted to be part of a dominant Serbian state in the Balkans–the “Greater Serbia” that Serbian separatists had long envisioned. In early May 1992, two days after the United States and the European Community (precursor to the European Union) recognized Bosnia's independence, Bosnian Serb forces with the backing of Milosevic and the Serb-dominated Yugoslav army launched their offensive with a bombardment of Bosnia's capital, Sarajevo. They attacked Bosniak-dominated town in eastern Bosnia, including Zvornik, Foca, and Visegrad, forcibly expelling Bosniak civilians from the region in a brutal process that later was identified as “ethnic cleansing.” (Ethnic cleansing differs from genocide in that its primary goal is the expulsion of a group of people from a geographical area and not the actual physical destruction of that group, even though the same methods–including murder, rape, torture and forcible displacement–may be used.)
Though Bosnian government forces tried to defend the territory, sometimes with the help of the Croatian army, Bosnian Serb forces were in control of nearly three-quarters of the country by the end of 1993, and Karadzic's party had set up their own Republika Srpska in the east. Most of the Bosnian Croats had left the country, while a significant Bosniak population remained only in smaller towns. Several peace proposals between a Croatian-Bosniak federation and Bosnian Serbs failed when the Serbs refused to give up any territory. The United Nations (U.N.) refused to intervene in the conflict in Bosnia, but a campaign spearheaded by its High Commissioner for Refugees provided humanitarian aid to its many displaced, malnourished and injured victims.
Attack on Srebrenica: July 1995
By the summer of 1995, three towns in eastern Bosnia–Srebrenica, Zepa and Gorazde–remained under control of the Bosnian government. The U.N. had declared these enclaves “safe havens” in 1993, to be disarmed and protected by international peacekeeping forces. On July 11, however, Bosnian Serb forces advanced on Srebrenica, overwhelming a battalion of Dutch peacekeeping forces stationed there. Serbian forces subsequently separated the Bosniak civilians at Srebrenica, putting the women and girls on buses and sending them to Bosnian-held territory. Some of the women were raped or sexually assaulted, while the men and boys who remained behind were killed immediately or bussed to mass killing sites. Estimates of Bosniaks killed by Serb forces at Srebrenica range from around 7,000 to more than 8,000.
After Bosnian Serb forces captured Zepa that same month and exploded a bomb in a crowded Sarajevo market, the international community began to respond more forcefully to the ongoing conflict and its ever-growing civilian death toll. In August 1995, after the Serbs refused to comply with a U.N. ultimatum, the North Atlantic Treaty Organization (NATO) joined efforts with Bosnian and Croatian forces for three weeks of bombing Bosnian Serb positions and a ground offensive. With Serbia's economy crippled by U.N. trade sanctions and its military forces under assault in Bosnia after three years of warfare, Milosevic agreed to enter negotiations that October. The U.S.-sponsored peace talks in Dayton, Ohio in November 1995 (which included Izetbegovic, Milosevic and Croatian President Franjo Tudjman) resulted in the creation of a federalized Bosnia divided between a Croat-Bosniak federation and a Serb republic.
Though the international community did little to prevent the systematic atrocities committed against Bosniaks and Croats in Bosnia while they were occurring, it did actively seek justice against those who committed them. In May 1993, the U.N. Security Council created the International Criminal Tribunal for the Former Yugoslavia (ICTY) at The Hague, Netherlands. It was the first international tribunal since the Nuremberg Trials in 1945-46 and the first to prosecute genocide, among other war crimes. Radovan Karadzic and the Bosnian Serb military commander, General Ratko Mladic, were among those indicted by the ICTY for genocide and other crimes against humanity.
Over the better part of the next two decades, the ICTY charged more than 160 individuals of crimes committed during conflict in the former Yugoslavia. Brought before the tribunal in 2002 on charges of genocide, crimes against humanity and war crimes, Slobodan Milosevic served as his own defense lawyer; his poor health led to long delays in the trial until he was found dead in his prison cell in 2006. In 2007, the International Court of Justice issued its ruling in a historic civil lawsuit brought by Bosnia against Serbia. Though the court called the massacre at Srebrenica genocide and said that Serbia “could and should” have prevented it and punished those who committed it, it stopped short of declaring Serbia guilty of the genocide itself.
