So this one is a bit different:
In 1990, during the process of disintegration of Yugoslavia, the Socialist Republic of Bosnia and Herzegovina held its first, last and only free elections. The 7 members of the Presidency (2 Bosniak, 2 Serb, 2 Croat, 1 Other), the municipal assemblies and the two chambers of the Parliament were elected simultaneously.
The Parliament was formed by two chambers that sat together. One was the Chamber of Citizens, formed by 130 members elected by proportional representation from seven multi-member constituencies that roughly corresponded with the republic's judicial districts.
The other was the Chamber of Municipalities, which sent one member for every municipality regardless of population (and one extra member for Grad Sarajevo, the umbrella municipality of the various Sarajevo municipalities) adding up to 110 members. The Chamber of Municipalities was elected through a two-round system.
Both chambers, although elected separately, sat as one single chamber, much like Croatia in 1991.
I have the winners for each municipality from the Chamber of Municipalities but no numbers (so maybe a map will come) and some extra numbers for the Chamber of Citizens. The elections of 1990 were marked by irregularities, with 5% of void votes, higher in urban areas. Plus it is nice to show a map of Bosnia without its brutalised municipal borders.
The short-lived government that followed was a coalition of the three main nationalist parties, the SDA, the SDS BiH and the HDZ za BiH. The Serbs held the Speaker's seat, the Croats the premiership and the Bosniaks the chairmanship of the Presidency.
The parties, as they were:
- The Party of Democratic Action (Stranka demokratske akcije, SDA) was the main party for Bosniaks (or as they were known then, 'Muslim Bosnians'). The party was led by Alija Izetbegović, who would go on to become the Chair of the Presidency in 1990. He became known for his Islamic Declaration of 1983, a text - censored by Yugoslav authorities - where he called for Islamic renewal and defended something similar to Christian democracy, but Muslim. He was something of a martyr, being imprisoned over the book in 1983. The SDA was also active in Serbia and Montenegro, where it acted as the political vehicle of the Muslim minority in Sandžak.
- The Serb Democratic Party (Српска демократска странка / Srpska demokratska stranka, SDS) was the main political party of Serbs. The party was created as a twin of the Croatian SDS, which had become the primary party of the Serb minority there. The party was conservative and nationalistic and had close ties to the Milosevic regime. It was lead by Radovan "Butcher of Bosnia" Karadžić, who would go on to become a war criminal.
- The Croat Democratic Union of Bosnia and Herzegovina (Hrvatska demokratska zajednica Bosne i Hercegovine, HDZ) was the main political party of Bosnian Croats. The party was established as the Bosnian branch of Franjo Trudman's HDZ. Like its sister/mother party in Zagreb, the party was nationalist and conservative. It was led by Stjepan Kljuić, a pro-cooperation moderate who would be removed from the party leadership by Trudman's acolytes in Sarajevo in 1992. The HDZ achieved the highest share of support from "its" ethnic group.
- The League of Communists of Bosnia and Herzegovina - Party of Democratic Change (Savez komunista Bosne i Hercegovine - Stranka demokratskih promjena / Савез комуниста Босне и Херцеговине — Странка демократских промјена, SK BiH - SDP) was the ruling party for the previous half-century. It was led by Nijaz Duraković. The party argued for a multi-ethnic Yugoslavia and Bosnia (Yugoslavism) but was contrary to the economic reforms undertaken by Ante Marković at the federal level and until changing its mind, opposed to multi-party democracy, which makes its name extra hypocritical.
- The Union of Reform Forces of Yugoslavia (Savez reformskih snaga Jugoslavije / Савез реформских снага Југославије, SRSJ) was the party led by Ante Marković. In 1990, it would run for election in Serbia, Bosnia, Montenegro, Macedonia. The Union of Reform Forces was a split from the Communists and formed by reform-minded and liberal members as well as individuals from the Yugoslavist opposition. Like the League of Communists, the party advocated for a multi-ethnic Yugoslavia and Bosnia, but also advocated for free markets and multi-party democracy. It was led by Selim Beslagic.
- The coalition of the League of Socialist Youth (Savez socijalističke omladine, SSO), the Democratic Socialist Alliance and the Democratic Alliance of Greens which ran together in several constituencies. They were minor centre-left parties. They obtained two seats.
- The Democratic Socialist Alliance (Demokratski socijalistički savez, DSS), running alone in Banja Luka.
- The Muslim Bosniak Organisation (Muslimanska bošnjačka organizacija, MBO), a minor Bosniak nationalist party with a name that evoked the Austro-Hungarian and inter-war Yugoslav Muslim Organization.
