World War I and beyond. On 28 June 1914, Archduke Franz Ferdinand, heir presumptive to the Austro-Hungarian Empire, visited the Bosnian capital, Sarajevo. A group of six assassins (Cvjetko Popović, Gavrilo Princip, Muhamed Mehmedbašić, Nedeljko Čabrinović, Trifko Grabež, and Vaso Čubrilović) from the Yugoslavist group Mlada Bosna, supplied with arms by the Serbian Black Hand, gathered on the street where the Archduke's motorcade was to pass, with the intention of assassinating him. The political objective of the assassination was to break off Austria-Hungary's South Slav provinces, which Austria-Hungary had annexated from the Ottoman Empire, so they could be combined into a Yugoslavia.
