The Yugoslav wars were a series of violent conflicts in the territory of the former Yugoslavia that went on in the 1990s. They comprised two series of successive wars affecting all of the six former Yugoslav republics.

Conflicts in the west

• War in Slovenia (1991) — a short 10-day war.
• War in Croatia (1991–1995)
• War in Bosnia (1992–1995)

The wars in Slovenia and Croatia were initially fought in the name of forcibly keeping Yugoslavia united. They soon became overtly nationalist in character, with a clash between the Serbian and Croatian nationalist ideologies personified by Presidents Slobodan Milošević and Franjo Tuđman of Serbia and Croatia respectively. The Serb-Croat conflict was greatly complicated in Bosnia by the presence of the large Muslim (Bosniak) population, which caused it to develop into a three-way conflict that was by far the bloodiest of the Yugoslav wars.

The Yugoslav wars in the west were ended by the military defeat of Serbia/Yugoslavia in Slovenia and Croatia, and the signing of the Dayton Agreement in 1995 for Bosnia.

Conflicts in the east and south

• Kosovo War (1996-1999)
• Conflict in Macedonia (2001)
• Conflict in Southern Serbia (2001)

In Kosovo, Macedonia, and Serbia proper, the conflicts were typified by racial and political tension between Slav governments and Albanian national minorities which sought autonomy or independence.

The conflict in Kosovo broke out into a full-scale war in 1999, while the Macedonian and southern Serbian conflicts were characterised by armed clashes between state security forces and ethnic Albanian guerrillas. The war in Kosovo ended with NATO intervention, although further widespread unrest in Kosovo broke out in 2004. Internationally-overseen negotiations restored peace in southern Serbia and Macedonia but the situation in both regions remains fragile.
