Vakhtang I "Gorgasali" (Georgian: ვახტანგ I გორგასალი) (c.

439 or 443 — 502 or 522) ascended the throne of Kartli at the age of fifteen. According to the Life of Vakhtang Gorgasali, the king was given at his birth an Iranian name Varazkhosrovtang, rendered in Georgian as Vakhtang. The name may indeed be derived from Iranian *warx-tang (vahrka-tanū) — "wolf-bodied", a possible reflection of the wolf cult in ancient Georgia.
At that time Kartli was continually being invaded by the Persians from the south and by the Ossetians from the north. The situation was no better in western Georgia: the Byzantines had captured all the lands from Egrisi to Tsikhegoji.
King Vakhtang led a victorious campaign against the Ossetians, freed the captive princess (his older sister), and signed several treaties with the Caucasian mountain tribes to secure their cooperation in the struggle against foreign conquerors. Then he carried out another campaign in western Georgia, freed that region from the Byzantines, reinforced the authority of KingGubaz, and returned in triumph to Kartli.
King Vakhtang was remarkable in faith, wisdom, grace, virtue, and appearance (he towered above all others at a stately seven feet ten inches). He spent many nights in prayer and distributed alms to the poor, in this way dedicating his life to God.
King Vakhtang could fight tirelessly in battle. Vested in armor and fully armed, he could carry a war-horse on his shoulders and climb from Mtskheta to the Armazi Fortress in the mountains outside the city. The holy king was judicious in politics, displayed great composure, and preserved a sense of calm even when critical decisions needed to be made.
On the brow of Vakhtang's military helmet was depicted a wolf, and on the back, a lion. Catching a glimpse of the helmet with the wolf and lion, the Persians would cry out to one another: “Dar' az gurgsar!” (“Beware of the wolf 's head!”) This was the source of King Vakhtang's appellation “Gorgasali.”
During King Vakhtang's reign the Georgian Church was first recognized as autocephalous. When the holy king banished the pagan fire-worshippers from Georgia, he also sent a certain Bishop Mikael — who was inclined to the Monophysite heresy, which had been planted in Georgia by the Persians — to Constantinople to be tried by the patriarch. The bishop had disgracefully cursed the king and his army for rising up against the Monophysites. In fact, he was so infuriated that when King Vakhtang approached him to receive his blessing, he kicked him in the mouth and broke several of his teeth. The patriarch of Constantinople subsequently defrocked Bishop Mikael and sent him to a monastery to repent.
More importantly perhaps, the patriarch and the Byzantine emperor then sent to the patriarch of Antioch several clergymen whom King Vakhtang had chosen for consecration. In Antioch the patriarch consecrated twelve of these clergymen as bishops and enthroned a certain Petre as the first Catholicos of Georgia.
By espousing pro-Roman policy, Vakhtang further alienated his nobles, who sought Iranian support against the king’s encroachments on their autonomy. In 482, Vakhtang put to death his most influential vassal, Varsken, vitaxa of Gogarene, a convert to Zoroastrianism and a champion of Iran’s influence in the Caucasus, who had executed his Christian wife, 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, 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.
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.
