Assassination of Archduke Franz Ferdinand

The assassination of Archduke Franz Ferdinand of Austria, heir presumptive to the Austro-Hungarian throne, and his wife, Sophie, Duchess of Hohenberg, occurred on 28 June 1914 in Sarajevo when they were mortally wounded by Gavrilo Princip. Princip was one of a group of six assassins also containing Muhamed Mehmedbašić, Vaso Čubrilović, Nedeljko Čabrinović, Cvjetko Popović and Trifun Grabež coordinated by Danilo Ilić, a Bosnian Serb and a member of the Black Hand secret society. The political objective of the assassination was to break off Austria-Hungary's South Slav provinces so they could be combined into a Yugoslavia. The conspirators' motives were consistent with the movement that later became known as Young Bosnia. The assassination led directly to World War I when Austria-Hungary subsequently issued an ultimatum to the Kingdom of Serbia, which was partially rejected. Austria-Hungary then declared war on Serbia, triggering actions leading to war between most European states.

The Serbian military conspiracy was organized by Chief of Serbian Military Intelligence Dragutin Dimitrijević with the assistance of Major Vojislav Tankosić and spy Rade Malobabić. Tankosić armed the assassins with bombs and pistols and trained them. The assassins were given access to the same clandestine network of safe-houses and agents that Malobabić used for the infiltration of weapons and operatives into Austria-Hungary.
