| Tito’s partisans’ fight was a socialist revolution. What I am in effect arguing is that this aim under instructions given from the Comintern was not so publicly propagated by Tito’s partisans in order to avoid upsetting Moscow’s western allies.
Origin of the Yugoslav Uprising and Civil War and the Soviet Union
In occupied Yugoslavia (partitioned by Germany, Hungary, Bulgaria and Italy after twelve days of the April War of 1941) popular resistance to the invading forces took the form of an armed uprising. This uprising followed by the Yugoslav civil war initiated early in July 1941 when the Central Committee of the CPY called upon the peoples of Yugoslavia to take up arms, and in the course of that same year the uprising spread to all parts of Yugoslavia, but in the first instance to the parts of the country settled by Serbs. The proclamation of the uprising of all Yugoslav people was populated by the Politburo of the Central Committee of the CPY on July 4th, 1941, the day after Stalin’s speech to the Soviet people on the radio. This proclamation became an inspiration to transform previous sabotage actions to the partisan war against occupiers3. From that moment the passive conduct of the CPY, influenced by the Ribetrop–Molotov Pact (August 23rd, 1939) was transformed into a “mobile state”. Considerable territory in western Serbia was liberated. After proclamation of the liberated territory as the U˛ice Republic, the Supreme Headquarters of the Yugoslav partisans under Tito’s command established itself there.
The CPY had direct radio communication with the Comintern which was facilitated by Josip Kopinič, a very good friend of J. B. Tito. J. Kopinič was sent by the Comintern to Yugoslavia in February 1940 to “carry out a special task”4. The headquarters of this radio was located in Zagreb and J. Kopinič was sending his reports to Moscow from there until 1944. Tito started to use this radio from January 1941 in order to inform Moscow personally5.
This radio was part of a Soviet agency in Yugoslavia which was established in summer 1940. The Soviet military attaché in Yugoslavia set apparatus with a secret code to the correspondent of the United Press, Miša Brašić, in June 1941, when the Soviets left Belgrade after the German attack on the USSR.
After the outbreak of Tito’s partisans’ uprising in July 1941 this radio-apparatus was used by the Supreme Headquarters of the partisan units6. Moreover, in the summer of 1941 the CPY maintained connections with Moscow with three independent radio-apparatuses operated by Josip Kopinič in Zagreb, Mustafa Golubić and Miša Brašić in Belgrade. It is generally acknowledged that due to them, the Comintern collected very important information about the political and military situation in Yugoslavia during the critical period of the German attack on the Soviet Union (June–December 1941).
The Soviet Union was the only country which broke off diplomatic relations with the Yugoslav government-in-exile (May 1941).
