Franz Ferdinand (1863–1914) Archduke of Austria.
Nephew of Franz Josef, he became heir to the throne of Austria-Hungary in 1896. His belief in authoritarian central government was balanced by a wish to reorganize the empire into a federation of states on ethnic lines. While visiting Sarajevo in the province of Bosnia and Herzegovina, he was assassinated by a pro-Serbian revolutionary, Gavrilo Princip, on 28 June 1914. The ensuing accusations and threats between Austria-Hungary and Serbia and their allies led to the start of World War I.
