the overwhelming majority of casualties being Muslim Bosniaks. The Ten-Day War (1991) was a brief military conflict between Slovenian TO (Slovenian Territorial Defence) and the Yugoslav People's Army ("JNA") following Slovenia's declaration of independence. The Croatian War of Independence (1991–1995) was fought in modern-day Croatia between the Croatian government (having declared independence from the Socialist Federal Republic of Yugoslavia) and both the Yugoslav People's Army ("JNA") and Serb forces, who established the self-proclaimed Republic of Serbian Krajina ("RSK") within Croatia. The Bosnian War (1992–1995) involved several ethnically-defined factions within Bosnia and Herzegovina: Bosniaks, Serbs, and Croats, as well as a smaller Bosniak faction led by Fikret Abdić. The Siege of Sarajevo (1992–1995) marked the most violent urban warfare in Europe since World War II at that time, as Serb forces bombarded and attacked Bosnian-controlled and populated areas of the city. War crimes occurred, including ethnic cleansing and the destruction of civilian property. The final fighting in the Croatian and Bosnian wars ended in 1995 with the success of Croatian military offensives against Serb forces. This led to the mass exodus of Serbs from Croatia, Serb losses to Croat and Bosniak forces, and the signing of the Dayton Agreement, which internally partitioned Bosnia and Herzegovina into a Republika Srpska and a Bosniak-Croat Federation. The Kosovo War (1998–1999) was a war between Albanian separatists and Yugoslav military and Serb paramilitary forces in Kosovo. That conflict began in 1996 and escalated in 1998, with increasing reports of atrocities. In 1999, the NATO, led by the United States, launched air attacks against Yugoslavia (then composed of only Serbia and Montenegro) to pressure the Yugoslav government to end its military operations against Albanian separatists in Kosovo. The intervention lacked UN approval yet was justified by NATO based on accusations of war crimes committed by Yugoslav military forces working alongside nationalist Serb paramilitary groups. Finally, after months of bombing, Yugoslavia conceded to NATO's demands, and NATO forces (later UN peacekeeping forces) occupied Kosovo. The South African Border War (1990) was a border war between Zambia, Angola, and Namibia that began in 1966 and ended in 1990. Civil wars and guerrilla wars The First Liberian Civil War occurred from 1989 until 1997 and led to the death of around 200,000 people. The Ethiopian Civil War (1991) was an internal conflict that had been raging for over twenty years. Its end coincided with the establishment of a coalition
