Belisario is an Italian male given name of Latin origin, meaning "warrior" or "strong." It is derived from the Latin word 'belliarius,' which was used to describe a soldier who took part in battles. The name Belisario is also associated with the Eastern Roman Emperor Justinian I's most able and faithful general, Flavius Belisarius (c. 505 – 565 AD), who played a significant role in the expansion of the Byzantine Empire during the 6th century.
