The term Kosovo War or Kosovo Conflict is often used to describe two sequential and at times parallel armed conflicts in Kosovo: 1.

1996–1999: War between Serbian and Yugoslav security forces and the Kosovo Liberation Army (KLA), an ethnic Albanian guerilla group seeking secession from the former Yugoslavia.

2.

1999: 1999 NATO bombing of the Federal Republic of Yugoslavia between March 24 and June 10, 1999, during which NATO attacks Yugoslav targets and Albanian guerrillas continue battles with Yugoslav forces, amidst a massive displacement of population in Kosovo.
