World War II: Yugoslav Partisans convene the first meeting of the Anti-Fascist Council for the National Liberation of Yugoslavia at Bihać in northwestern Bosnia.
The Anti-Fascist Council for the National Liberation of Yugoslavia, commonly abbreviated as the AVNOJ, was a deliberative and legislative body that was established in Biha, Yugoslavia, in November 1942. It was established by Josip Broz Tito, the leader of the Yugoslav Partisans, an armed resistance movement led by the Communist Party of Yugoslavia to resist the Axis occupation of the country during World War II.
The AVNOJ reconvened in Jajce in 1943 and in Belgrade in 1945, shortly after the war in Europe ended. Between the sessions, it operated through its presidency, its executive council, and the National Committee for the Liberation of Yugoslavia. The committee was granted authority normally wielded by cabinets. While Tito presided over the committee, the AVNOJ sessions and its presidency were chaired by Ivan Ribar. The second session of the AVNOJ proclaimed itself Yugoslavia's new legislative body and decided that it should be a multi-ethnic federal state.
By 1944, the Western Allies and the Yugoslav government-in-exile recognised the AVNOJ as the all-Yugoslav legislative body. The third session of the AVNOJ was convened in preparation of the Constitutional Assembly when the Yugoslav Parliament was convened again in 1945. Decisions of the AVNOJ determined there would be six units in the federation and defined their borders. It also took over the position of the legitimate ruling body of Yugoslavia from the government-in-exile in dealings with the Allies.
The Yugoslav Partisans, or the National Liberation Army, officially the National Liberation Army and Partisan Detachments of Yugoslavia, was the Communist-led Anti-fascist resistance to the Axis powers (chiefly Germany) in occupied Yugoslavia during World War II. Led by Josip Broz Tito, the Partisans are considered to be Europe's most effective anti-Axis resistance movement during World War II.Primarily a guerilla force at its inception, the Partisans developed into a large fighting force engaging in conventional warfare later in the war, numbering around 650,000 in late 1944 and organized in four field armies and 52 divisions. The main stated objectives of the Partisans were the liberation of Yugoslav lands from occupying forces and the creation of a federal, multi-ethnic socialist state in Yugoslavia.
The Partisans were organized on the initiative of Tito following the Axis invasion of Yugoslavia in April 1941, and began an active guerrilla campaign against occupying forces after Germany invaded the Soviet Union in June. A large-scale uprising was launched in July, later joined by Draža Mihailović's Chetniks, which led to the creation of the short-lived Republic of Užice. The Axis mounted a series of offensives in response but failed to completely destroy the highly mobile Partisans and their leadership. By late 1943 the Allies had shifted their support from Mihailović to Tito as the extent of Chetnik collaboration became evident, and the Partisans received official recognition at the Tehran Conference. In Autumn 1944, the Partisans and the Soviet Red Army liberated Belgrade following the Belgrade Offensive. By the end of the war, the Partisans had gained control of the entire country as well as Trieste and Carinthia. After the war, the Partisans were reorganized into the regular armed force of the newly established Federal People's Republic of Yugoslavia.
