Eristavi 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 rank of prince. Holders of the title were ex-officio commanders of a banner, wore a distinctive dress, ring, belt and spear. Some high-ranking eristavis were also titled as eristavt-eristavi, i. e. duke of dukes, erismtavari was a similar title chiefly endowed upon the pre-Bagratid rulers of Iberia and later used interchangeably with the eristavi. These families were known simply as Princes Eristov in Russia. List of Georgian dukes Eristoff, Vodka House of Sidamoni Djavakhishvili, GSE, volume 4, page 192, Tbilisi
