Franz Ferdinand was an Archduke (which is like a prince) of Austria and, from 1896 until his death, he was next in line to be the emperor of the former country called Austria-Hungary. He was killed in the city Sarajevo by Gavrilo Princip.
On June 28th, 1914, while riding in the motorcade through the streets of Sarajevo, Franz Ferdinand and his wife Sophie were shot and killed by Gavrilo Princip -- one of seven young Bosnians and Black Hand recruits. The assassination provided 'justification' for Austria to take hard action against Serbia.
