Млада Босна
Žerajić and Špiro Soldo were leaders of the secret society "Freedom" () established in 1905/1906. Žerajić's friendship with Vladimir Gaćinović and his attempted assassination of Varešanin also inspired the members of the revolutionary movement Young Bosnia, including Gavrilo Princip. Gaćinović was the real ideologue of the revolutionary movement Young Bosnia and advocated tyrannicide as a method of political struggle. Some authors, including Vladimir Dedijer, emphasise that the basis for this method of political struggle is the cult of "Kosovo tyrannicide".
