On Sunday, 28 June 1914, Archduke Franz Ferdinand of Austria and his wife Sophie, Duchess of Hohenberg were assassinated in Sarajevo by Gavrilo Princip with a pistol at point blank range during a visit that had been announced two months prior. General Oskar Potiorek, Governor of the Austrian provinces of Bosnia and Herzegovina had invited Franz Ferdinand and Countess Sophie to the opening of a hospital. The Archduke knew that the visit would be dangerous, knowing his uncle, Emperor Franz Josef, had been the subject of an assassination attempt by the Black Hand in 1911.
