On 28th June 1914, Archduke Franz Ferdinand of Austria, heir apparent to the Austro-Hungarian throne, and his wife, Sophie, Duchess of Hohenberg, were shot dead in Sarajevo, by Gavrilo Princip, one of a group of six Bosnian Serb assassins coordinated by Danilo Ilić. The political objective of the assassination was to break Austria-Hungary's south-Slav provinces off so they could be combined into a Greater Serbia or a Yugoslavia. The assassins' motives were consistent with the movement that later became known as Young Bosnia. Serbian military officers stood behind the attack. The assassination led to the outbreak of World War I one month later.
