About 88 percent of eligible voters in Slovenia voted to secede from the Socialist Federal Republic of Yugoslavia.

An independence referendum was held in the Republic of Slovenia on 23 December 1990. Both the ruling center-right coalition and the left-wing opposition supported the referendum and called on voters to support Slovenian independence.

The Socialist Federal Republic of Yugoslavia, known from 1945 to 1963 as the Federal People's Republic of Yugoslavia, commonly referred to as Socialist Yugoslavia or simply Yugoslavia, was a country in Central and Southeast Europe. It was established in 1945, following World War II, and lasted until 1992, dissolving amid the onset of the Yugoslav Wars. Spanning an area of 255,804 square kilometres (98,766 sq mi) in the Balkans, Yugoslavia was bordered by the Adriatic Sea and Italy to the west, Austria and Hungary to the north, Bulgaria and Romania to the east, and Albania and Greece to the south. It was a one-party socialist state and federation governed by the League of Communists of Yugoslavia, and had six constituent republics: Bosnia and Herzegovina, Croatia, Macedonia, Montenegro, Serbia, and Slovenia. Within Serbia was the Yugoslav capital city of Belgrade as well as two autonomous Yugoslav provinces: Kosovo and Vojvodina.
