Млада Босна
In the autumn of 1913, Stojanović commenced the final year of his secondary education. National Unity was visited that year by a group of activists of Young Bosnia who were university students in Prague, Vienna, and Switzerland. They held a series of lectures for the members of the association, explaining their views on the current political situation, and promoting the unity of South Slavic peoples in their struggle to liberate themselves from Austria-Hungary. These lectures influenced Stojanović to adopt a Yugoslavist stance. At the beginning of 1914, Ilić and Stojanović became, respectively, the president and the vice-president of National Unity, which numbered 34 members, including four Muslims and four Croats. At that time, National Unity was one of the most active groups of Young Bosnia.
