Meaning and history
This name comes from the old Italian name Napoleone, used most notably by the French emperor Napoléon Bonaparte (1769-1821), who was born on Corsica. The etymology is uncertain, but it is possibly derived from Old German Nibelungen meaning "sons of mist", a name used in Germanic legend to refer to the keepers of a hoard of treasure, often identified with the Burgundians. Alternatively, it could be connected to the name of the Italian city of Napoli (Naples).
