An independence referendum was held in Bosnia and Herzegovina between 29 February and 1 March 1992, following the first free elections of 1990 and the rise of ethnic tensions that led to the breakup of Yugoslavia. Independence was strongly favored by Bosniak and Bosnian Croat voters while Bosnian Serbs boycotted the referendum or were prevented from participating by Bosnian Serb authorities. The total turn out of voters was 63.4% (less than two-thirds, casting doubt on its validity) of which 99.7% voted for the independence of Bosnia and Herzegovina. On 3 March, Chairman of the Presidency of Bosnia and Herzegovina Alija Izetbegović declared the independence of the Republic of Bosnia and Herzegovina and the parliament ratified the action. On 6 April, the United States and the European Economic Community recognized Bosnia and Herzegovina as an independent state and on 22 May it was admitted into the United Nations.
In November 1990, months after Slovenia and Croatia declared their independence, the first free elections were held, putting nationalist parties into power with three parties. These were the Party of Democratic Action (SDA), led by Alija Izetbegović, the Serbian Democratic Party (SDS), led by Radovan Karadžić, and the Croatian Democratic Union (HDZ), led by Stjepan Kljuić. Izetbegović was elected as the Chairman of the Presidency of Bosnia and Herzegovina. Jure Pelivan, of the HDZ, was elected as the Chairman of the Council of Ministers of Bosnia and Herzegovina. Momčilo Krajišnik, of the SDS, was elected as the speaker of Parliament of Bosnia and Herzegovina.
