The Battle of Blarathon was fought in 592 near Ganzak between a combined Eastern Roman (Byzantine)-Persian force and a Persian army led by the usurper Bahram Chobin. The combined army was led by John Mystacon, Narses, and the Persian prince Khosrau II. The Roman-Persian force was victorious, ousting Bahram Chobin from power and reinstating Khosrau as ruler of the Sassanid Empire. Khosrau was swiftly reinstated upon the Persian throne, and as agreed upon returned Dara and Martyropolis. Additionally, he agreed to a new partition of the Caucasus by which the Sassanids handed over to the Romans many cities, including Tigranokert, Manzikert, Baguana, Valarsakert, Bagaran, Vardkesavan, Yerevan, Ani, Kars, and Zarisat. Most of the Kingdom of Iberia, including the cities of Ardahan, Lori, Dmanisi, Lomsia, Mtskheta, and Tontio became Roman dependencies. Also, the city of Cytaea was given to Lazica, also a Roman dependency. The Battle of Blarathon altered the course of Roman-Persian relations dramatically, leaving the former in the dominant position. The extent of effective Roman control in the Caucasus reached its zenith historically.
