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.
The primary source of Franz Ferdinand's unpopularity however related to the policies he intended to apply once he assumed the throne. He proposed to replace Austro-Hungarian dualism with 'Trialism,' a triple monarchy in which the empire's Slavs would have an equal voice in government with the Germans and Magyars.
