An independence referendum was held in the Autonomous Province of Kosovo and Metohija between 26 and 30 September 1991. The Assembly of Kosovo had declared the Republic of Kosova a sovereign and independent state on 22 September 1991. Over 99% of voters voted in favour of independence, with a turnout of 87%. The referendum was boycotted by Serbs living in the region, who comprised around 10% of the population.
Background
In order to pass, the referendum required a turnout of at least 66.7% and at least half of those voting in favour.
The only United Nations member who recognised the Republic of Kosova was Albania, with a resolution recognising the country passed in the Parliament of Albania on 21 October.
