Following the Croatian parliamentary elections of 1990 and escalating ethnic tensions tied to the broader breakup of Yugoslavia, Croatian leaders sought a popular mandate for separation from the federal state. The deteriorating political situation and rising nationalism across Yugoslav republics made a formal vote on independence an urgent political priority.
On 19 May 1991, Croatia held a referendum on independence from Yugoslavia. With 83 percent of eligible voters participating, 93 percent endorsed independence. Croatia formally declared independence and the dissolution of its association with Yugoslavia on 25 June 1991, though it accepted a three-month moratorium under the Brioni Agreement at the urging of the European Community and the CSCE.
During the moratorium, the war in Croatia intensified, and on 8 October 1991 the Croatian Parliament severed all remaining ties with Yugoslavia. In 1992, European Economic Community member states granted Croatia diplomatic recognition, and Croatia was admitted to the United Nations, securing its place as a sovereign state in the international order.
Political Outcome
Referendum passed with 93% in favor; Croatia declared independence on 25 June 1991 and achieved UN membership in 1992.
