Starting in 1941, Yugoslav communists under the leadership of Josip Broz Tito organized their own multi-ethnic resistance group, the Partisans, who fought against both Axis and Chetnik forces. On 29 November 1943, the Anti-Fascist Council for the National Liberation of Yugoslavia (AVNOJ) with Tito at its helm held a founding conference in Jajce where Bosnia and Herzegovina was reestablished as a republic within the Yugoslavian federation in its Habsburg borders. During the entire course of World War II in Yugoslavia, 64.1% of all Bosnian Partisans were Serbs, 23% were Muslims and 8.8% Croats.
