Serbia and Montenegro, known until 2003 as the Federal Republic of Yugoslavia, FR Yugoslavia (FRY) or simply Yugoslavia, was a country in Southeast Europe located in the Balkans that existed from 1992 to 2006, following the breakup of the Socialist Federal Republic of Yugoslavia. The country bordered Hungary to the north, Romania to the northeast, Bulgaria to the southeast, North Macedonia to the south, Croatia and Bosnia and Herzegovina to the west, and Albania to the southwest. The state was founded on 27 April 1992 as a federation comprising the Republic of Serbia and the Republic of Montenegro. In February 2003, it was transformed from a federal republic to a political union until Montenegro seceded from the union in June 2006, leading to the full independence of both Serbia and Montenegro.

The Kosovo War was an armed conflict in Kosovo that lasted from 28 February 1998 until 11 June 1999. It was fought between the forces of the Federal Republic of Yugoslavia, which controlled Kosovo before the war, and the Kosovo Albanian separatist militia known as the Kosovo Liberation Army (KLA). The conflict ended when the North Atlantic Treaty Organization (NATO) intervened by beginning air strikes in March 1999 which resulted in Yugoslav forces withdrawing from Kosovo.
