The Bosnian War, known in Serbo-Croatian as Rat u Bosni i Hercegovini (Рат у Босни и Херцеговини), was a profoundly destructive international armed conflict that engulfed Bosnia and Herzegovina from 1992 to 1995. This harrowing period in the heart of the Balkans is generally understood to have commenced on April 6, 1992, although a series of violent incidents had already begun to fray the fabric of peace much earlier. The conflict finally drew to a close with the signing of peace accords on December 14, 1995.

At its core, the war involved a brutal struggle between the forces loyal to the Republic of Bosnia and Herzegovina on one side, and those aligned with two distinct proto-states: Herzeg-Bosnia and Republika Srpska. These aspiring entities received significant leadership and material support from neighbouring Croatia and Serbia, respectively, deeply implicating them in the conflict.

The Unraveling of Yugoslavia and Bosnia's Path to Independence

The Bosnian War was an integral, tragic chapter in the wider breakup of Yugoslavia, a process that began with Slovenia's and Croatia's declarations of independence from the Socialist Federal Republic of Yugoslavia in 1991. Bosnia and Herzegovina, a diverse and multi-ethnic republic, was home to a complex mosaic of populations: primarily Muslim Bosniaks, constituting about 44% of the population; mainly Orthodox Serbs, making up roughly 32.5%; and primarily Catholic Croats, at approximately 17%. As the surrounding republics moved towards sovereignty, Bosnia and Herzegovina itself held a referendum for independence on February 29, 1992.

However, this move was met with staunch opposition from political representatives of the Bosnian Serbs, who largely boycotted the referendum and subsequently rejected its outcome. Foreshadowing their rejection, the Assembly of the Serb People in Bosnia and Herzegovina had already adopted the Constitution of the Serbian Republic of Bosnia and Herzegovina on February 28, 1992, signaling their intent to forge their own path. Following Bosnia and Herzegovina's declaration of independence, which quickly gained international recognition, and the withdrawal of its then-President, Alija Izetbegović, from the previously signed Cutileiro Plan (which had proposed a division of Bosnia into ethnically based cantons), Bosnian Serb forces began to mobilize. Led by Radovan Karadžić and receiving substantial backing from the Serbian government of Slobodan Milošević and the Yugoslav People's Army (JNA), their objective was to secure territories they considered ethnically Serb. This mobilization rapidly escalated, and war soon engulfed the entire country, tragically accompanied by widespread ethnic cleansing.

The Belligerents and the Escalation of Conflict

Initially, the conflict pitted units of the Yugoslav Army, which later transformed into the formidable Army of Republika Srpska (VRS), against two main forces. These were the nascent Army of the Republic of Bosnia and Herzegovina (ARBiH), predominantly composed of Bosniaks, and the Croat forces operating under the Croatian Defence Council (HVO). However, the complex dynamics of the war soon saw internal shifts. Tensions between the Bosniak and Croat forces, initially aligned against the Bosnian Serbs, began to mount throughout late 1992, culminating in the escalation of the Croat–Bosniak War in early 1993, adding another layer of tragic complexity to the already brutal landscape.

The Bosnian War was characterized by an appalling level of violence and human suffering. It saw bitter fighting across frontlines, the indiscriminate shelling of cities and towns, and systematic campaigns of ethnic cleansing designed to forcibly remove specific ethnic groups from certain territories. Furthermore, the conflict was marked by systematic mass rape, primarily perpetrated by Serb forces, and to a lesser extent, by Croat and Bosniak forces. Iconic and horrific events such as the devastating Siege of Sarajevo, the longest siege of a capital city in modern warfare, and the Srebrenica massacre, declared a genocide by international courts, became enduring symbols of the conflict's barbarity.

Shifting Tides and International Intervention

Despite their initial military superiority, largely due to the substantial weapons and resources inherited from the JNA, the Serb forces eventually lost momentum. A pivotal shift occurred in 1994 when the Bosniaks and Croats, following the Washington Agreement, forged an alliance and created the Federation of Bosnia and Herzegovina, uniting their forces against the Republika Srpska. International involvement also played a crucial role. Notably, Pakistan, disregarding the United Nations' arms embargo, airlifted anti-tank missiles to the Bosnian Muslims, providing a vital, albeit controversial, boost to their defense capabilities. After the widespread international outcry following the Srebrenica massacre and the shelling of Sarajevo's Markale market, NATO intervened directly in 1995. Operation Deliberate Force, a targeted bombing campaign against the positions of the Army of the Republika Srpska, proved to be a decisive factor in bringing the war to an end.

The Path to Peace and Lasting Consequences

The final push for peace began with intensive negotiations held in Dayton, Ohio, which concluded on November 21, 1995. These negotiations laid the groundwork for the General Framework Agreement for Peace in Bosnia and Herzegovina, more commonly known as the Dayton Accords, which was formally signed in Paris on December 14, 1995, officially ending the war.

The aftermath of the Bosnian War left an indelible scar. By early 2008, the International Criminal Tribunal for the former Yugoslavia (ICTY) had convicted numerous individuals of war crimes in connection with the conflict: forty-five Serbs, twelve Croats, and four Bosniaks. The human cost was staggering: estimates suggest approximately 100,000 people lost their lives. Furthermore, over 2.2 million people were displaced from their homes, making it the most devastating conflict in Europe since the end of World War II. The systematic use of sexual violence as a weapon of war was also a horrific aspect, with an estimated 12,000 to 50,000 women raped, predominantly by Serb forces, with most of the victims being Bosniak women. The war fundamentally reshaped the geopolitical landscape of the Balkans and left a complex legacy of trauma, reconciliation challenges, and ongoing efforts to build a stable and unified Bosnia and Herzegovina.
