Starting in 1941, Yugoslav communists under the leadership of Josip Broz Tito organized their own multi-ethnic resistance group, the Partisans, who fought against Axis, Ustaše, and Chetnik forces. They too, committed numerous atrocities, mainly against political opponents of all ethnicities. Some Bosnian Muslims joined the Waffen-SS and the SS "Handschar" division, an SS division of the Nazis that pledged allegiance to both Adolf Hitler and NDH leader, Ante Pavelić. The division was the first SS division which was constituted of non-Germans. On 25 November 1943 the Anti-Fascist Council of National Liberation of Yugoslavia 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 Ottoman borders. Military success eventually prompted the Allies to support the Partisans. On 6 April 1945 Sarajevo was captured by the Partisans. The end of the war resulted in the establishment of the Federal People's Republic of Yugoslavia, with the constitution of 1946 officially making Bosnia and Herzegovina one of six constituent republics in the new state.
