War with the Byzantine Empire
Still young and proud of his early achievements, George I decided to rekindle the old tensions between his kingdom and the Byzantine Empire, which had pursued imperialist ambitions in the Caucasus region since at least the reign of Justinian (527–565). Considering himself the true successor of those who sought to unite the Georgian lands, the loss of Kakheti and Hereti drove him to seek new territories in the southwest. He set his sights on Tao, the former Kingdom of the Iberians and hereditary domain of the early Bagrationi dynasty. This region had been bequeathed by testament to Emperor Basil II by David III Kurapalates as a form of punishment for the latter’s support of the rebel Bardas Phokas; part of it had later been granted by Byzantine to Bagrat III.
Since the year 1000, Basil II had been fully engaged in a long and brutal war against the Bulgarians—earning him the epithet Bulgar Slayer—and thus had little time to concern himself with Georgia. Taking advantage of this, George I invaded the disputed territory for the first time in 1015 or 1016, without provoking an immediate military response from the emperor. However, Aristakes Lastivertsi reports a written exchange between Basil and the Georgian monarch, in which the emperor declared:“—Abandon the portion of the Kuropalate’s inheritance that I granted to your father, and be content to reign over your own patrimony.”“—Of what my father possessed, I will not yield a single house to anyone.” »Following this defiance, Basil II personally intervened despite his ongoing difficulties in Bulgaria. Yet the renewed alliance between Georgia and Byzantium’s principal rival, the Fatimid Caliphate—against which Basil had waged war between 992 and 995—initially repelled the Greek forces.
By 1018, however, Bulgaria had been completely subdued by Byzantine arms: Tsar Presian II was deposed, and his kingdom was made a province of the Byzantine Empire. Soon after, the Fatimid Caliph al-Hakim bi-Amr Allah died and was succeeded by his inexperienced son, Ali az-Zahir, who proved too weak to maintain any focus on Georgian affairs. Left isolated on the international stage, George I now faced the full might of the Byzantine army.
The two forces met on the plains of Basiani, in Tao. George retreated, burning the town of Oltisi to block the Greek advance, but was overtaken at Kola. Nearby, at the village of Shirimni, the Georgian rearguard was attacked by the Byzantine vanguard, leading to a fierce battle on 11 September 1021. The engagement was narrowly won by Basil II’s troops, with the emperor himself present on the battlefield, though many of Georgia’s greatest generals perished.
The Georgian army hastily withdrew toward Samtskhe, pursued by the Byzantines, who ravaged Javakheti and set fire to the city of Artaani.
A pursuit ensued following the initial encounters. From Samtskhe, upon sighting the approach of enemy forces, King George I withdrew to the region of Trialeti. Once there, he prevented the Byzantine troops from catching up, while his own army was reinforced by soldiers from Kakheti-Hereti and the mountains of the Greater Caucasus. Emperor Basil II, in turn, retreated and spent the winter at Artaani, using the season to devastate the surrounding regions in retaliation. Later, he established his camp within imperial territory near Trebizond, where he received the submission of Hovhannes-Smbat III of Armenia—a vassal of Georgia—and initiated the first attempts at negotiation with the Georgian kingdom. Around the same time, Vaspurakan was ceded to Byzantium by King Senekerim-Hovhannes, who sought protection from the advancing Seljuks. Surrounded on all sides, Georgia found itself in a precarious position and, as a last resort, intervened in the internal affairs of the Byzantine Empire.
In 1022, the strategos of Anatolia, Nikephoros Xiphias—a distinguished Byzantine general who had previously fought in the war against the Bulgarians—rose in rebellion alongside his namesake, Nikephoros Phokas (nicknamed “the Twisted-Neck”), son of the former rebel Bardas Phokas. Together, they opposed Emperor Basil II. Officially, their revolt stemmed from their exclusion from the Caucasian campaign; however, in reality, the rebellion was instigated by George I, who exploited the envy and resentment of the Byzantine generals. On 11 September 1022, exactly one year after the Georgian defeat at Shirimni, Basil II decisively crushed the revolt and brought the rebels to Constantinople. Realizing the Georgian monarch’s involvement, Basil once again turned his forces against Georgia, compelling George I to sue for peace.
George attempted to recover from this setback by sending Prince Zviad Liparitisdze with a large contingent to meet the Byzantine emperor. During the winter of 1022–1023, he seized the opportunity to reoccupy Tao. Acting on the treacherous counsel of several Georgian nobles, George I ordered an attack on the imperial troops. Personally leading his army onto the plain of Basiani, he engaged the Byzantines in a fierce and bloody battle. The Greek division of the enemy army was routed, yet the contingents from the Kievan Rus’ continued their assault with great tenacity, ultimately defeating the Georgian forces. Many Georgian nobles and soldiers fell in battle.
Peace negotiations resumed soon afterward, resulting in a treaty between Basil II and George I. Under its terms, the young prince Bagrat, the king’s eldest son—then three years old—was sent to Constantinople as a hostage for three years. Georgia was also compelled to cede fourteen fortresses and to renounce all claims to the territories of David Kuropalates. Consequently, Georgia lost control over Tao, Javakheti, Shavsheti, the plains of Basiani, and the towns of Artaani and Kola. The first Byzantine–Georgian war thus concluded with a decisive Byzantine victory.
