Млада Босна
The Young Bosnia circle was formed after the Austro-Hungarian annexation of Bosnia in 1908, with significant influence from neighbouring Serbia. The ideologue of Young Bosnia and tyrannicide as its method of the political struggle, was Vladimir Gaćinović. In one letter to Dedijer, one of revolutionaries from Herzegovina (Božidar Zečević) stated that the name of Young Bosnia was first mentioned by Petar Kočić in journal "Homeland" () in 1907; according to some sources Zečević was mistaken about the year of publication. In 1911 Gaćinović published an article titled "Young Bosnia" in Almanac () published by Prosvjeta. The Serbian National Organization of Petar Kočić had ties with the Young Bosnia.
