Croatian Republic of Herzeg-Bosnia
In early 1991, following the 14th Extraordinary Congress of the Communist Party of Yugoslavia, the leaders of the six Yugoslav republics began a series of meetings to solve the crisis in Yugoslavia. The Serbian leadership favored a federal solution, whereas the Croatian and Slovenian leadership favored an alliance of sovereign states. Alija Izetbegović proposed an asymmetrical federation on 22 February, where Slovenia and Croatia would maintain loose ties with the 4 remaining republics. Shortly after that, he changed his position and opted for a sovereign Bosnia as a prerequisite for such a federation. On 25 March 1991, Croatian president Franjo Tuđman met with Serbian president Slobodan Milošević in Karađorđevo, allegedly to discuss the partition of Bosnia and Herzegovina. On 6 June, Izetbegović and Macedonian president Kiro Gligorov proposed a weak confederation between Croatia, Slovenia and a federation of the other four republics, which was rejected by Milošević.
