Shushanik, daughter of the Armenian Mamikonid prince Vardan II and a hero of the earliest surviving piece of Georgian literature. By this act, Vakhtang placed himself in open confrontation with his Iranian suzerain. Vakhtang called on the Armenian princes and the Huns for co-operation. After some hesitation, the Armenians under Vardan's nephew Vahan Mamikonian, joined forces with Vakhtang. The allies were routed and Iberia was ravaged by Iranian punitive expeditions in 483 and 484, forcing Vakhtang into flight to Roman-controlled Lazica (modern western Georgia). After Peroz's death in the war with the Hephthalites in 484, his successor Balash reestablished peace in the Caucasus. Vakhtang was able to resume his reign in Iberia, but did not betray his pro-Roman line. Once the Hundred Years Peace between Iran and Rome collapsed, Kavadh I of the Sassanids summoned Vakhtang as a vassal to join in a new campaign against Rome. Vakhtang refused, provoking an Iranian invasion of his kingdom. Then about 60, he had to spend the last years of his life in war and exile, fruitlessly appealing for the Roman aid. The chronology of this period is confused, but by 518 an Iranian viceroy had been installed at the Iberian town of Tiflis, founded—according to Georgian tradition—by Vakhtang and designated as the country's future capital. According to the LVG, Vakhtang died fighting an Iranian invading army at the hands of his renegade slave who shot him through an armpit defect of his armor. The wounded king was transported to his castle at Ujarma where he died and was interred at the cathedral in Mtskheta. Javakhishvili puts Vakhtang's death at c. 502. If Toumanoff's identification of Procopius’ Gurgenes with Vakhtang is true, the king might have ended his reign in 522 by taking refuge in Lazica, where he possibly died around the same time. Gurgenes’ family members—Peranius, Pacurius, and Phazas—had careers in the Roman military. Family According to the LVG, Vakhtang was survived by three sons. Dachi, Vakhtang's eldest son by his first marriage to the Iranian princess Balendukht (who died at childbirth), succeeded him as king of Iberia and had to return to Iranian allegiance. Two younger sons by Vakhtang's second marriage to the Roman lady Elene—Leon and Mihrdat—were enfeoffed of the southwestern Iberian provinces of Klarjeti and Javakheti in which Leon's progeny—the Guaramids—traditionally followed pro-Roman orientation. Both these lines survived in Iberia into the 8th century, being succeeded by their energetic
