Yugoslav Partisans - Formation and Early Rebellion

Formation and Early Rebellion

Operation Barbarossa, the Axis invasion of the Soviet Union, began on 22 June 1941.

The first communist military unit, the Sisak Brigade, was established on 22 June 1941, the day Nazi Germany invaded the Soviet Union. This was ignored in official Yugoslav Historiography as it was not related to the Partisan movement. The first uprising, led by Tito, occurred two weeks later, in Serbia.

The Communist Party of Yugoslavia formally decided to launch an armed uprising on 4 July, a date which was later marked as Fighter's Day – a public holiday in the SFR Yugoslavia. One Žikica Jovanović Španac shot the first bullet of the campaign on 7 July, later the Uprising Day of the Socialist Republic of Serbia (part of SFR Yugoslavia).

On 10 August in Stanulović, a mountain village, the Partisans formed the Kopaonik Partisan Detachment Headquarters. Their liberated area, consisting of nearby villages, was called the "Miners Republic" and lasted 42 days. The resistance fighters formally joined the ranks of the Partisans later on.

On 21 December 1941 Partisans formed the 1st Proletarian Assault Brigade (1. Proleterska Udarna Brigada) – the first regular Partisan military unit, capable of operating outside its local area. In 1942 Partisan detachments officially merged into the People's Liberation Army and Partisan Detachments of Yugoslavia (NOV i POJ) with an estimated 236,000 soldiers in December 1942.

The extent of support for the Partisan movement varied according to region and nationality, reflecting the existential concerns of the local population and authorities. The first Partisan uprising occurred in Croatia on 22 June 1941, when forty Croatian Communists staged an uprising in the Brezovica woods between Sisak and Zagreb. An uprising occurred in Serbia two weeks later led by Tito (Uzice Republic), but it was quickly defeated by the Axis forces and support for the Partisans in Serbia thereafter dropped. Partisan numbers from Serbia would be diminished until 1943 when the Partisan movement gained upswing by spreading the fight against the axis. Increase of number of Partisans in Serbia, similarly to other republics, came partly in response to Tito's offer of amnesty to all collaborators on 17 August 1944. At that point tens of thousands of Chetniks switched sides to the Partisans. The amnesty would be offered again after German withdrawal from Belgrade on 21 November 1944 and 15 January 1945.

It was a different story for Serbs in Axis occupied Croatia who turned to the multi-ethnic Partisans, or the Serb Royalist Chetniks whose brutality mirrored that of the Ustashi. Historian Tim Judah notes that in the early stage of the war the initial preponderance of Serbs in the Partisans meant in effect a Serbian civil war had broken out. A similar civil war existed within the Croatian national corpus with the competing national narratives provided by the Ustashi and Partisans.
