Pharnavaz had introduced a military-administrative organization based on a network of regional governors or "eristavi". The insignia of the eristavi, received from the king, constituted a sceptre, a special signet ring, belt and armament. Iberia had in total seven eristavis, in Colchis, Kakheti, Khunani (modern-day northern Azerbaijan), Samshvilde (Kvemo Kartli), Tsunda (included Javakheti, Kola and Artaani), Odzrkhe and Klarjeti. The kingdom had one spaspet who was under the direct control of the royal power based in Inner Kartli. Eristavates mimicked aspects of Achaemenid "satrapies" and Seleucid "strategoi". The major motive of later historian of the chronicles was to convince posterity that the basic political structure of Kartli was created by the very first Georgian monarch in the wake of Wars of Alexander the Great; was of Achaemenid administrative system and had remained stable throughout Hellenistic, Parthian and Sasanian times. In this way, the long-term viability and stability of the Georgian realm are established.
