On March 3, 1992, Bosnia-Herzegovina declared independence from Yugoslavia following a referendum vote. Within days, Bosnian Serb forces backed by the Yugoslav army began shelling Sarajevo, the country’s capital. What followed was three years of systematic killing, mass expulsion, and sexual violence targeting Bosniak (Bosnian Muslim) and Croatian civilians. By 1995, roughly 100,000 people had been killed — 80 percent of them Bosniaks. The war also produced some of the worst atrocities seen in Europe since World War II, culminating in the Srebrenica massacre, which international courts later ruled a genocide.
To understand how Bosnia reached this point, it is necessary to look at the decades before the war. After World War II, the Balkan states — Bosnia-Herzegovina, Serbia, Montenegro, Croatia, Slovenia, and Macedonia — were folded into the Federal People’s Republic of Yugoslavia. For decades, the country held together under the iron rule of Josip Broz Tito. When Tito died in 1980, that unity began to fracture. Nationalist movements gained strength across the republics, and in the mid-1980s, Serbian politician Slobodan Milosevic deliberately stoked ethnic tensions between Serbs and their Bosniak, Croatian, and Albanian neighbors. By 1991, Slovenia, Croatia, and Macedonia had declared independence, and Yugoslavia was effectively coming apart.
Bosnia itself was a multi-ethnic republic. By 1991, its population of just over four million was 44 percent Bosniak, 31 percent Serb, and 17 percent Croat. A coalition government formed in late 1990 represented all three groups, led by Bosniak leader Alija Izetbegovic. But Serbian separatists, led by Radovan Karadzic, had no interest in a shared state. They envisioned a “Greater Serbia” — a dominant Serbian nation carved out of the Balkans. Karadzic’s party blocked the independence referendum in many Serb-populated areas, but Bosnia declared independence anyway. The United States and European Community recognized it within days. Two days after that recognition, Bosnian Serb forces opened fire on Sarajevo.
The siege of Sarajevo became one of the longest in modern warfare. Bosnian Serb forces positioned snipers in the surrounding hills, turning the city’s streets into killing zones. Civilians risked their lives simply moving through the city. One stretch of road earned the name “Sniper Alley” for the constant threat of gunfire. Shells struck hospitals, markets, and residential buildings. Sarajevo’s infrastructure collapsed, leaving residents without consistent heat, water, or food, particularly during the brutal winter months.
Snipers were a constant threat throughout the siege. Civilians were shot in the open street, often while going about ordinary tasks. A single gunshot could end a life within seconds, with no warning. The toll on Sarajevo’s population was relentless.
Mortar attacks on civilian gathering points were deliberate and repeated. On August 28, 1995, a mortar shell struck the Markale marketplace in central Sarajevo, killing and wounding dozens of people who had gathered to buy and sell goods. It was not the first such attack on the market. The international community, which had largely watched the conflict from a distance, was finally forced to respond.
While Sarajevo endured the siege, Bosnian Serb forces carried out a campaign of ethnic cleansing across eastern Bosnia. Towns with large Bosniak populations — including Zvornik, Foca, and Visegrad — were targeted in coordinated attacks. Bosniak civilians were expelled from their homes, subjected to violence, and in many cases killed. The goal was to remove non-Serb populations from territory that Serbian separatists claimed as their own. By the end of 1993, Bosnian Serb forces controlled more than three-quarters of the country.
The violence against civilians was not incidental — it was systematic. Serbian forces detained, beat, and executed Bosniak men. Women were raped as a weapon of war. Entire communities were wiped out or permanently displaced. The brutality in towns like Visegrad was documented by journalists and later confirmed by international war crimes investigators.
The human cost was staggering. Morgues filled with the bodies of civilians. Hospitals struggled to treat the wounded while themselves coming under attack. Sarajevo’s Kosevo Hospital was struck by shellfire on June 16, 1995, killing two people and wounding six more. Patients and medical staff worked in conditions of constant danger.
The United Nations designated three towns in eastern Bosnia — Srebrenica, Zepa, and Gorazde — as “safe havens” in 1993. These enclaves were meant to be disarmed and protected by international peacekeepers. In practice, the protection was inadequate. Dutch UN peacekeepers stationed in Srebrenica were overwhelmed when Bosnian Serb forces, commanded by General Ratko Mladic, advanced on the enclave on July 11, 1995.
Once Serb forces took control of Srebrenica, they immediately began separating the population. Women, children, and the elderly were loaded onto buses and driven into Bosnian-held territory. Many women were raped or assaulted during this process. The men and boys who remained were either killed on the spot or transported by bus to mass execution sites. Serbian forces killed between 7,000 and 8,000 Bosniak men and boys in the days that followed — the single largest mass killing in Europe since the Holocaust.
The bodies of the victims were buried in mass graves across the eastern Bosnian countryside. After the war ended, investigators began the grim work of locating, exhuming, and identifying the remains. Mass graves were found in villages including Pilica, Kamenica, Konjevic Polje, and Budak. Many of the graves had been disturbed — Serb forces had moved remains from primary graves to secondary sites in an effort to conceal the scale of the killings.
Identifying victims from mass graves required painstaking forensic work. The Podrinje Identification Project, based in Tuzla, stored approximately 3,900 body bags and worked to match skeletal remains with personal belongings and clothing recovered from burial sites. DNA analysis played a major role in making positive identifications. Personal items — a watch, a shoe, a piece of clothing — were often the only clues available to investigators trying to put names to the dead.
Funerals for identified victims continued for years after the war ended. Each burial brought another wave of grief to survivors who had spent years not knowing whether their family members were alive or dead. Mass funerals at the Potocari Memorial Cemetery near Srebrenica became annual events as more remains were identified and returned to families.
The wider war ground on through 1995. Displaced civilians crowded into shelters, refugee camps, and whatever spaces offered safety. Bosnian soldiers fought to hold remaining territory while civilians endured shortages of food, medicine, and basic supplies. The UN High Commissioner for Refugees provided assistance to the displaced and malnourished, though the scale of the crisis overwhelmed available resources.
After the Sarajevo marketplace bombing in August 1995, NATO launched airstrikes against Bosnian Serb positions. Combined with ground offensives by Bosnian and Croatian forces, the military pressure forced a turning point. UN trade sanctions had already badly damaged Serbia’s economy, and after three years of war, Milosevic agreed to negotiate in October 1995. Peace talks held in Dayton, Ohio in November 1995 — attended by Izetbegovic, Milosevic, and Croatian President Franjo Tudjman — produced an agreement that created a federalized Bosnia and ended the fighting.
Even after the Dayton Agreement, the destruction left behind was immense. In areas that had been held by Serb forces, some residents set fires as they withdrew rather than leave intact neighborhoods to others. Graveyards in Sarajevo had expanded dramatically during the siege, with fresh burials taking place in parks and open lots when traditional cemeteries ran out of space.
The United Nations Security Council established the International Criminal Tribunal for the Former Yugoslavia (ICTY) to prosecute those responsible for war crimes and genocide. It was the first international criminal tribunal since the Nuremberg Trials of 1945–46, and the first ever convened specifically to prosecute genocide. In total, 161 individuals were indicted for crimes committed during the conflict. Slobodan Milosevic was brought before the tribunal in 2002 on charges of genocide, crimes against humanity, and war crimes. His trial was delayed repeatedly due to poor health, and he died in his cell in 2006 before a verdict was reached.
Radovan Karadzic, who had ordered the siege of Sarajevo and the ethnic cleansing campaigns, was convicted of war crimes. Ratko Mladic, who commanded the forces that carried out the Srebrenica massacre, stood trial before the ICTY in proceedings that involved nearly 600 witnesses and lasted more than four years. In November 2017, the tribunal found Mladic guilty of genocide and other crimes against humanity and sentenced him to life imprisonment. In 2007, the International Court of Justice, ruling on a civil lawsuit brought by Bosnia against Serbia, characterized the Srebrenica massacre as genocide and ruled that Serbia had failed to prevent and punish those who committed it.
Even amid the destruction, moments of quiet resistance stood out. On September 12, 1992, cellist Vedran Smailovic performed inside the bombed-out National Library in Sarajevo — a building that had been deliberately targeted and burned, destroying centuries of irreplaceable manuscripts and books. Smailovic played in the ruins as an act of defiance, a reminder that the people of Sarajevo refused to be reduced to victims.
