The fallout from Bosnia and Herzegovina’s declaration of independence from Yugoslavia led to some of the worst atrocities in Europe since the end of World War II. During the war in Bosnia, which lasted from 1992 to 1995, civilians of all ethnicities — Muslims, Serbs and Croats — became victims of horrible crimes. Bosnian Muslims would suffer the greatest losses, with thousands being slaughtered by Serb forces.

The violence throughout the region led to the first international war crimes tribunal since Nuremberg. The tribunal’s final defendant was Ratko Mladić. Known as the “Butcher of Bosnia,” the general commanded Bosnian Serb forces during the war and oversaw the brutal, years-long siege of Sarajevo. He was also accused of ordering the massacre of more than 7,000 men and boys in Srebrenica in 1995.

In 2017, more than 20 years after he was first indicted, Mladić was convicted of genocide and crimes against humanity. The FRONTLINE documentary The Trial of Ratko Mladić gives exclusive access to both the prosecution and defense teams, offering insight into Mladić’s role in the complicated war in Bosnia. Here, we highlight some of the key moments in the war and the events that led to Mladić’s sentencing.

March 1, 1992 Bosnia and Herzegovina, a multi-ethnic republic that had been a part of Yugoslavia, held an independence referendum.

For more than three decades after World War II, Yugoslavia was a communist federation made up of six republics (Bosnia and Herzegovina, Croatia, Macedonia, Montenegro, Serbia and Slovenia). In the years after the 1980 death of Josip Broz Tito, who ruled Yugoslavia for three decades, there was a rise in nationalism and separatism among the republics. Croatia and Slovenia declared their independence from Yugoslavia in 1991.

The splintering of the former Yugoslavia continued with Bosnia and Herzegovina’s referendum in March 1992. Bosnian Serbs, who made up 31 percent of the republic’s population (compared to 43 percent of Muslims and 17 percent of Croats), boycotted the vote, wishing to remain connected to Serbia. Voters overwhelmingly chose independence.

April 1992 On April 5, just as the international community was preparing to recognize Bosnia and Herzegovina’s independence, violence erupted in Bosnia’s capital, Sarajevo. “On that date, thousands of people took to the streets in spontaneous peace marches,” a report by a United Nations panel of experts read. “The largest body of demonstrators headed towards the Parliament building and other buildings reportedly seized by Serb forces. Unidentified gunmen were then reported to have fired into the crowd. One protestor was confirmed dead.”

Serb leaders proclaimed a “Serb Republic of Bosnia and Herzegovina,” and received backing and weapons from neighboring Serbia and the Serb-controlled Yugoslav Army. The siege of Sarajevo began as Serb forces struck areas occupied by Bosnian Muslims and Croats with artillery.

May 1992 Radovan Karadžić, the political leader of the Bosnian Serbs, announced the creation of a Bosnian Serb army, which would absorb members from the Yugoslav army. Gen. Ratko Mladić was named the commander.

Bosnian Serb forces held positions overlooking the city and used their superior weapons to launch a “constant bombardment” of Sarajevo. A 1994 UN report said a “quiet day” of shelling during the siege meant 200 to 300 impacts, while an “active day” could be 800 to 1,000 impacts. The report said targets of the shelling included hospitals; radio and TV stations; buildings that housed political, cultural and religious structures; and civilian areas like parks and schools.

July 1992 As Serb forces drove thousands of Bosnian Muslims from their homes in the northwest part of the country, reports of ethnic cleansing began to emerge.

Several months before, Serb forces had taken control of the town of Prijedor in what would later be called an “illegal coup d’état,” according to a document from the International Criminal Tribunal for the former Yugoslavia. In Prijedor, Bosnian Serbs established camps where primarily non-Serb detainees were held in “appalling” conditions. More than 3,000 Muslims and Croats were killed in the region. The 2013 discovery of a mass grave would offer further evidence of mass killings.

Mladić would later be charged with several massacres that happened over the course of six days in July 1992. The prosecution argued that he had “firm command and control over the [Bosnian Serb army and forces] throughout the ethnic cleansing campaign in Prijedor municipality, killing more than 1,500 Muslims and detaining thousands more in brutal and inhumane conditions.” Prosecutors said that by 1993, the targeted communities “chillingly no longer existed.”

A witness called by Mladić’s defense team said he had never seen or heard about Mladić’s presence in Prijedor. He later told FRONTLINE filmmakers, “I deliberately avoided knowing about certain things so as not to suffer repercussions.”

August 1992 Images of Bosnian Serb camps near Prijedor drew the world’s attention when TIME magazine published a cover showing a crowd of emaciated men behind barbed wire. “No one anywhere can pretend any longer not to know what barbarity has engulfed the people of the former Yugoslavia,” the accompanying story read.

April-May 1993 In mid-April 1993, the UN Security Council declared the town of Srebrenica, in eastern Bosnia, a “safe area which should be free from any armed attack or any hostile act.” By then, Srebrenica hosted refugees from areas where Bosnian Serb forces had pushed out non-Serbs. The UN Security Council would pass another resolution in May declaring five other places in Bosnia “safe areas”: Bihac, Gorazde, Sarajevo, Tuzla and Zepa.

May 25, 1993 The UN Security Council formally established the International Criminal Tribunal for the former Yugoslavia, the first international war crimes tribunal since the aftermath of World War II.

Feb. 5, 1994 In the 22nd month of the siege of Sarajevo, a mortar attack launched by Serb forces killed 68 people and wounded 200 in a market in the city center. At the time, it was described in media reports as “the worst single atrocity” of the war. Days after the attack, the North Atlantic Treaty Organization issued an ultimatum to Bosnian Serbs: withdraw heavy guns from the mountains around the city, or face air strikes. The Serbs’ military leaders initially rejected the ultimatum, but complied with demands by Feb. 20.

Feb. 28, 1994 NATO engaged in the first combat operations in its history, shooting down Bosnian Serb aircrafts while enforcing a UN Security Council-declared no-fly-zone over Bosnia and Herzegovina.

Jan. 1, 1995 A four-month ceasefire took effect, brokered in part by former U.S. President Jimmy Carter. It broke down six weeks before its expiration, when Bosnian government forces began an offensive attack.

March 1995 Karadžić, the leader of the Bosnian Serbs, signed a document called “Directive No. 7.” It called for combat operations to “create an unbearable situation of total insecurity with no hope of further survival or life” for those living in the UN safe areas of Srebrenica and Zepa. It said that if UN forces left those areas, the plan was “breaking up and destroying the Muslim forces in these enclaves and definitively liberating” the area.

April 1995 The chief prosecutor of the international tribunal said Radovan Karadžić and Ratko Mladić were being investigated for masterminding a campaign of ethnic cleansing. “My strategy is to indict those in leadership positions, both civilian and military, who are responsible for serious violations of international law,” he said.

May 25, 1995 As the shelling of Sarajevo continued, NATO warplanes bombed an ammunition depot. American planes took part in the bombing, and U.S. President Bill Clinton backed the NATO air strikes. In retaliation, Bosnian Serb forces took more than 200 UN troops hostage and surrounded an additional 150.

July 6, 1995 Bosnian Serb forces launched an attack on Srebrenica. They were “in a position to take the town of Srebrenica itself” by July 9, according to the prosecution’s opening statement at Mladić’s trial.

July 11, 1995 Mladić’s forces entered Srebrenica to find it mostly empty. Thousands of people — mostly women, children and the elderly — had fled to nearby Potocari, while able-bodied men began trekking through the woods to reach the Muslim-controlled city of Tuzla. In video footage from that day, Mladić said, “Here we are, on 11 July 1995, in Serb Srebrenica. On the eve of yet another great Serb holiday, we give this town to the Serb people as a gift. Finally, the time has come to take revenge on the Turks [Muslims] in this region.”

That evening, Mladić told a Muslim representative in a nearby town, “In order to make a decision as a man and a commander, I need to have a decision from your people. Whether you want to survive, stay or disappear.”

July 12-13, 1995 Mladić and his senior officers separated males over the age of 16 from the rest of the refugees in Potocari, according to the prosecution’s opening statement. Women and children were put on buses and trucks and sent to Muslim-controlled territory.

During his trial, Mladić’s defense team argued that what was being cast as a deportation was actually a humanitarian evacuation. In video footage, Mladić is seen telling a crowd of refugees in Potocari, “Anyone who wants to leave will be transported, be they old or young. Don’t be afraid and don’t rush. Let the women and children go first. Please don’t panic. Be careful not to lose any children. Don’t be afraid. Nobody will harm you.”

Of the roughly 15,000 Muslim men who left Srebrenica the day before, the court said about a third were armed. Roughly 7,000 made it out of the area, while those who remained were trapped by a “wall of the Serb forces,” according to court documents. “On the morning of 13 July, many of the trapped men were captured along the road or turned themselves in,” prosecutors said. “The organized mass executions started on the morning of 13 July.”

The prosecution argued that Mladić was in command when crimes were being committed. “Only an army strictly controlled at the top could have managed to murder over 7,000 people in four days,” the prosecution said.

July 25, 1995 Mladić and Karadžić were indicted by the International Criminal Tribunal for the former Yugoslavia on charges of genocide; crimes against humanity “by persecuting Bosnian Muslim and Bosnian Croat civilians on national, political and religious grounds”; and being “criminally responsible for the unlawful confinement, murder, rape, sexual assault, torture, beating, robbery and inhumane treatment of civilians.”

Their indictments were amended in November 1995 to include charges of genocide and crimes against humanity in relation to Srebrenica.

Aug. 30, 1995 NATO launched a major bombing campaign against Bosnian Serb forces to pressure them to move heavy weapons away from Sarajevo and stop threatening other UN “safe areas.”

Bosnian President Alija Izetbegovic welcomed the air strikes as “the beginning of peace,” and said, “The world has finally done what it should have done a long, long time ago.” Karadžić called them a “moral disaster for the Western world and for the UN.”

September 1995 Taking advantage of the NATO air strikes, Bosnian Muslim and Croat forces seized territory from the Serbs. Media reports cast the loss of territory as the turning point in making Serbs more willing to negotiate.

October 1995 At the United States’ urging, a ceasefire agreement was reached on Oct. 5, but its implementation was delayed when the Bosnian government insisted on electricity being restored to Sarajevo first. The presidents of Bosnia and Serbia and Bosnian Serb leaders Karadžić and Mladić agreed to the ceasefire.

Nov. 21, 1995 The presidents of Bosnia, Serbia and Croatia agreed to a U.S.-brokered peace framework that was worked out in Dayton, Ohio over 20 days. Although Bosnia and Herzegovina would share a presidency and parliament, it would also be split into two political entities: Republika Srpska for Serbs, and the Federation of Bosnia and Herzegovina for Muslims and Croats. The agreement also called for all parties to cooperate with the investigation and prosecution of war crimes.

Dec. 14, 1995 The Dayton Peace Agreement was formally signed in Paris.

May 26, 2011 After evading capture for 16 years, Mladić was arrested in Serbia. During his nearly two decades in hiding, he was thought to have spent time in Republika Srpska and then Serbia, where he was under the protection of military figures and the Serbian president, Slobodan Milošević. In 2010, Mladić’s family filed a request to have him legally declared dead.

May 16, 2012 Mladić’s trial at The Hague began. The court would sit for 530 trial days and hear from nearly 600 witnesses.

Nov. 22, 2017 Mladić was found guilty on 10 out of 11 counts. He was convicted of “genocide and persecution, extermination, murder and the inhumane act of forcible transfer in the area of Srebrenica in 1995” and “persecution, extermination, murder, deportation and inhumane act of forcible transfer” in areas throughout Bosnia, and “murder, terror and unlawful attacks on civilians in Sarajevo” and “hostage-taking of UN personnel.” He was sentenced to life in prison. He appealed the conviction in 2018.
