Eristavi

Eristavi (Georgian:ერისთავი; literally, "head of the nation") was a Georgian feudal office, roughly equivalent to the Byzantine strategos and normally translated into English as "duke". In the Georgian aristocratic hierarchy, it was the title of the third rank of prince and governor of a large province. Holders of the title were ex-officio commanders of a military 'banner', wore a distinctive dress, ring, belt and spear and rode a particular breed of horse.
