The assassination of Archduke Franz Ferdinand, also called the Attack in Sarajevo or Sarajevo incident occurred on 28 June 1914 and was one of the key events that led to World War I. Archduke Franz Ferdinand of Austria, heir presumptive to the Austro-Hungarian throne, and his wife, Sophie, Duchess of Hohenberg, were assassinated by Bosnian Serb student Gavrilo Princip. They were shot at close range while being driven through Sarajevo, the provincial capital of Bosnia and Herzegovina, formally annexed by Austria-Hungary in 1908. Princip was part of a group of six Bosnian assassins together with Muhamed Mehmedbašić, Vaso Čubrilović, Nedeljko Čabrinović, Cvjetko Popović and Trifko Grabež coordinated by Danilo Ilić; all but one were Bosnian Serbs and members of a revolutionary movement later known as Young Bosnia.
