"light-cavalryman," 1530s, from German Husar, from Hungarian huszár "light horseman," originally "freebooter," from Old Serbian husar, variant of kursar "pirate," from Italian corsaro (see corsair). The original Hussars were bodies of light horsemen organized in Hungary late 15c., famed for activity and courage and elaborate semi-oriental dress. They were widely imitated elsewhere in Europe, hence the spread of the name.
