Passage: Golubić completed his primary education in Stolac, before relocating to Sarajevo to attend high school. In 1908, he moved to Belgrade for post-secondary studies, studying law at the University of Belgrade. Some of Golubić's classmates and contemporaries later recounted that Golubić was recruited by the Russian secret police, the Okhrana, in his youth. The historian Vladimir Dedijer later consulted the records of the Hoover Institution in an attempt to verify this claim, to no avail. Golubić did join Young Bosnia (), a multi-ethnic youth organization agitating for the separation of Bosnia and Herzegovina from Austria-Hungary. The organization's membership was around 70 percent Serb, 20 percent Bosnian Muslim and 10 percent Croat. Following the outbreak of the Balkan Wars in November 1912, Golubić joined the volunteer Chetnik detachment of Major Vojislav Tankosić. As part of their training, Tankosić ordered that Golubić and the other volunteers jump into the Sava from a railway bridge, "just to see whether you are going to fulfill all my orders."
