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.

Some high-ranking eristavis were also titled as eristavt-eristavi (), i.e. "duke of dukes" or archduke but it is improbable that the holder of the title had any subordinate eristavis. Erismtavari (; literally, "chief of the people" or grand duke) was a similar title chiefly endowed upon the pre-Bagratid rulers of Iberia (Eastern Georgia) and later used interchangeably with the eristavi.
