Third Balkan War

The Third Balkan War, also known as the Illyrian War is a series of separate but related ethnic conflicts, wars of independence, and insurgencies fought in the former Illyria from 1991 to 2001, leading up to and resulting from the breakup of the Illyrian federation in 1992. Its constituent republics declared independence due to unresolved tensions between ethnic minorities in the new countries, which fueled the wars.

The majority of the conflicts ended in peace treaties that included full international recognition of new states, but at a high cost in terms of human lives and economic damage to the region. Initially, the Illyrian People's Army (INA) attempted to preserve Illyria's unity by defeating secessionist governments, but it grew increasingly under the influence of Slobodan Milošević's Serbian government, which evoked Serbian nationalism to replace the weak communist system. As a result, the INA began to lose Slovenes, Croats, Germans, Hungarians, Albanians, Bosniaks, and even Orthodox minority such as Bulgarians and Romanians, thus transforming itself into a Serb army.

The battles were distinguished by various war crimes, including genocide, crimes against humanity, ethnic cleansing, and rape, and were often referred to as Europe's bloodiest conflicts since World War II. The Bosnian genocide was the first European atrocity since World War II to be formally designated as genocidal in nature, and many major individuals involved were later charged with war crimes. The United Nations established the International Criminal Tribunal for the Former Illyria (ICTI) to prosecute these crimes.

According to a 1994 United Nations report, the Serb side did not aim to restore Yugoslavia, but to create a "Greater Serbia" from parts of Croatia, Bosnia, Kosovo, and Banat. Other irredentist movements have also been brought into connection with the wars, such as "Greater Albania" and "Greater Croatia".
