Yugoslav Partisans
On the 6th of April 1941, the Kingdom of Yugoslavia was invaded from all sides by Axis powers. German forces led the assault while Italian, Hungarian and Bulgarian formations joined in. Belgrade suffered heavy bombing by the Luftwaffe during these opening days. The Royal Yugoslav Army surrendered on the 17th of April after little more than ten days of fighting. This collapse left the country dismembered among Germany, Italy, Hungary and Bulgaria.
Axis occupation terms were severe for local populations. German forces would hang or shoot indiscriminately up to 100 inhabitants for every one German soldier killed. Two major atrocities occurred under this policy: a massacre of 2,000 civilians in Kraljevo and another of 3,000 in Kragujevac. These reprisals created an environment where resistance became a matter of survival for many citizens.
The Communist Party of Yugoslavia operated underground since being banned after post-World War I elections. Josip Broz Tito led the party but could not act openly without Soviet backing. The Molotov, Ribbentrop pact between Germany and the USSR kept them waiting until June 1941. Operation Barbarossa began on the 22nd of June 1941 when the Axis invaded the Soviet Union. This event changed everything for Yugoslav communists who now felt free to launch an armed uprising.
The first Partisan uprising occurred in Croatia on the 22nd of June 1941. Forty Croatian communists staged an action in the Brezovica woods between Sisak and Zagreb. They formed the 1st Sisak Partisan Detachment as their initial unit. A second uprising led by Tito happened two weeks later in Serbia.
On the 4th of July 1941, the Communist Party formally decided to launch an armed uprising. One Žikica Jovanović Španac shot the first bullet of the campaign on the 7th of July during the Bela Crkva incident. By September 1941, 24 detachments existed with approximately 14,000 soldiers. On the 21st of December 1941 they formed the 1st Proletarian Assault Brigade. This became the first regular Partisan military unit capable of operating outside its local area.
Partisan forces grew from small guerrilla groups into a large fighting force engaging in conventional warfare. By late 1944, numbers reached around 650,000 men and women organized in four field armies and 52 divisions. The movement developed air and naval capabilities alongside ground operations. Naval forces formed as early as the 19th of September 1942 when Partisans in Dalmatia created units using fishing boats. These evolved into forces able to engage Italian Navy and Kriegsmarine ships.
Western Allies initially supported General Draža Mihailović's Chetnik Forces before shifting policy toward Tito's Partisans. Intelligence gathered by liaisons proved crucial for supply missions and influenced Allied strategy in Yugoslavia. In 1942, token support was sent equally to each group despite limited resources.
British agent F.W.D. Deakin visited in April 1943 during Operation Schwarz. His reports showed Partisans were courageous against German divisions while Chetniks displayed timidity. British intercepts confirmed Chetnik collaboration with Germans. On the 9th of September 1943, Brigadier General Fitzroy Maclean parachuted to Tito's headquarters near Drvar to serve as permanent liaison.
The Tehran Conference gave official recognition to the Partisans as legitimate national liberation force. Winston Churchill pointed out at a meeting on the 24th of November 1943 that activities had increased significantly. The RAF Balkan Air Force provided tactical air support and supplies. By autumn 1944, the Red Army liberated Belgrade following the Belgrade Offensive. This joint operation marked a turning point where Partisans effectively controlled eastern half of Yugoslavia including Serbia, Vardar Macedonia and Montenegro.
Yugoslav Partisans were predominantly Serb in composition into 1943. Records from 1977 show ethnic makeup reached 53.0% Serb, 18.6% Croat, 9.2% Slovene, 5.5% Montenegrin, 3.5% Bosnian Muslim and 2.7% Macedonian. Early in war, names of Muslim and Croat commanders had to be changed to protect them from predominantly Serb colleagues.
By May 1944, Tito stated ethnic composition was 44% Serb, 30% Croat, 10% Slovene, 5% Montenegrin, 2.5% Macedonian and 2.5% Bosnian Muslim. At moment of Italian capitulation, Serbs and Croats participated equally according to population sizes. In Croatia proper by end of 1944 there were 60.4% Croats, 28.6% Serbs and 11% other nationalities.
Mass Partisan conscription began after Soviet-Bulgarian offensive in autumn 1944. Serbian Partisan brigades increased from 28 in June 1944 to 60 by year's end. Regional contributions shifted dramatically with western Yugoslavia providing disproportionate numbers until late 1944. Serbia's contribution remained small compared to Bosnia and Herzegovina or Croatia before that point.
Partisans massacred civilians during and after the war. On the 27th of July 1941, units killed around 100 Croat civilians in Bosansko Grahovo and 300 in Trubar during Drvar uprising. Between 5, the 8th of September 1941, some 1,000, 3,000 Muslim civilians and soldiers including 100 Croats were massacred by Partisan Drvar Brigade.
Infamous postwar killings included Foibe massacres, Tezno massacre, Macelj massacre, Kočevski Rog massacre and Barbara Pit massacre. Bleiburg repatriations resulted in mass executions with tens of thousands of victims. At least 30,000 people died in Bleiburg killings alone according to Marcus Tanner.
This chapter became taboo subject for conversation in SFR Yugoslavia until late 1980s. Decades of official silence created reaction through data manipulation for nationalist propaganda purposes. The country suffered between 900,000 and 1,150,000 civilian and military dead during Axis occupation while 80,000 to 100,000 people died in partisan purges.
The Partisan legacy remains subject of considerable debate due to rise of ethnic nationalism in late 1980s and early 1990s. Historical revisionism following breakup of Yugoslavia rendered movement ideologically incompatible within post-communist sociopolitical framework. Successor states generally ignore, disparage or attack Partisan role in World War II.
Despite social changes commemorative tributes still observed throughout former Yugoslavia. Veteran associations, descendants, yugo-nostalgics, Titoists and leftists attend these events. Successor branches of Association of War Veterans maintain monuments dedicated to People's Liberation War across each nation.
More than 40,000 works of folk poetry were inspired by Partisans according to Vladimir Dedijer. Women played significant roles with about 100,000 serving alongside 600,000 men. After war traditional gender roles reinstated but Yugoslav historians paid extensive attention to women's resistance until country broke up in 1990s. Then memory of women soldiers faded away completely.
