Black Hand
Five members of The Black Hand were in Sarajevo, Serbia, on 28 June, 1914 where Archduke Franz Ferdinand, the heir to the throne in Austria-Hungary, visited with his wife. Ferdinand was driven through the city in a convertible car. The members of the Black Hand attempted to kill Ferdinand by throwing grenades at his car. One of the grenades bounced off his car and exploded under the car following Ferdinand's. One of the members swallowed cyanide and attempted to jump into the river, however the cyanide was old, and the river was shallow, so he was arrested. One of the men, a Bosnian student called Gavrilo Princip, went to a cafe after failing to kill Ferdinand.
