Franz Joseph I of Austria

Franz Joseph I (1830-1916) of the Hapsburg Dynasty was Emperor of Austria, Apostolic King of Hungary and King of Bohemia from 1848 until 1916. His 68-year reign, the third-longest in the recorded history of Europe, made him the longest-serving German-speaking monarch who is known to have at least nominally ruled.

It was the assassination of Franz Joseph's nephew and heir presumptive, Archduke Franz Ferdinand, in 1914, that led to World War I. Franz Joseph did not live to see the end of the war, or the collapse of his empire.

Franz Joseph I in Southern Victory
Franz Joseph I died in the second year of the Great War, before his empire and its allies, the Central Powers, emerged victorious in 1917.

Literary comment
Presumably, Franz Joseph I lived long enough to witness the Central Powers victory in the abbreviated World War I. However, he is not referenced, nor are his successors specifically identified.
