Adurbadagan and arran (Caucasian albania) in the late sasanian period

The article considers the Sasanian King Khusraw I Anushirwan (Pahlavi: Xusrō I Anōšīrvān) reforms to improve the empire’s military and administrative architecture during the wars with Byzantium and the Turks. The author discusses the establishment of the region or kust-ī Ādurbādagān, which allowed the nomination of Arrān’s general. The author believes that it was a key element in the Sassanian strategy to enforce both central and military power in the defense sensitive Caucasia challenged by the Byzantium and nomads. The reforms pulled Arrān (Albania) to be closer to the Sasanian crown, enforcing the dynastic ties between Sasanian shāhanshāh and Arrānshāh. These reforms facilitated the incorporation of Arranian (Albanian) troops into the Sasanian Army under Ādurbādagān’s general command to shield Ērānšahr from the Khazar’s and Turk’s incursions. The author argues that the reform initiated the projecting of Ādurbādagān’s name, military, and administrative functions in Arrān forming a strong interrelationship between the southern and northern sides of the Araxes as the entire Ādurbādagān šahr. Since Late Antiquity, Ādurbādagān and Arrān became interchangeable names and were in use on the northern bank of the Araxes.
