Medieval Georgia
Georgia embraced Christianity about the year 330; its conversion is attributed to a holy captive woman, St. Nino. During the next three centuries, Georgia was involved in the conflict between Rome—and its successor state, the Byzantine Empire—and the Persian Sāsānian dynasty. Lazica on the Black Sea (incorporating the ancient Colchis) became closely bound to Byzantium. Iberia passed under Persian control, though toward the end of the 5th century a hero arose in the person of King Vakhtang Gorgaslani (Gorgasal), a ruler of legendary valour who for a time reasserted Georgia’s national sovereignty. The Sāsānian monarch Khosrow I (reigned 531–579) abolished the Iberian monarchy, however. For the next three centuries, local authority was exercised by the magnates of each province, vassals successively of Persia (Iran), of Byzantium, and, after ad 654, of the Arab caliphs, who established an emirate in Tbilisi. (See Iran, ancient.)
Toward the end of the 9th century, Ashot I (the Great), of the Bagratid dynasty, settled at Artanuji in Tao (southwestern Georgia), receiving from the Byzantine emperor the title of kuropalates (“guardian of the palace”). In due course, Ashot profited from the weakness of the Byzantine emperors and the Arab caliphs and set himself up as hereditary prince in Iberia. King Bagrat III (reigned 975–1014) later united all the principalities of eastern and western Georgia into one state. Tbilisi, however, was not recovered from the Muslims until 1122, when it fell to King David IV (Aghmashenebeli, “the Builder”; reigned 1089–1125).
The zenith of Georgia’s power and prestige was reached during the reign (1184–1213) of Queen Tamar, whose realm stretched from Azerbaijan to the borders of Cherkessia (now in southern Russia) and from Erzurum (in modern Turkey) to Ganja (modern Gäncä, Azerbaijan), forming a pan-Caucasian empire, with Shirvan and Trabzon as vassals and allies.
The invasions of Transcaucasia by the Mongols from 1220 onward, however, brought Georgia’s golden age to an end. Eastern Georgia was reduced to vassalage under the Mongol Il-Khanid dynasty of the line of Hülegü, while Imereti, as the land to the west of the Suram range was called, remained independent under a separate line of Bagratid rulers. There was a partial resurgence during the reign (1314–46) of King Giorgi V of Georgia, known as “the Brilliant,” but the onslaughts of the Turkic conqueror Timur between 1386 and 1403 dealt blows to Georgia’s economic and cultural life from which the kingdom never recovered. The last king of united Georgia was Alexander I (1412–43), under whose sons the realm was divided into squabbling princedoms.
Turkish and Persian domination
The fall of Constantinople (modern Istanbul, Turkey) to the Ottoman Empire in 1453 isolated Georgia from western Christendom. In 1510 the Ottomans invaded Imereti and sacked the capital, Kʿutʿaisi. Soon afterward, Shah Ismāʿīl I of Iran (Persia) invaded Kartli. Ivan IV (the Terrible) and other Muscovite tsars showed interest in the little Christian kingdoms of Georgia, but the Russians were powerless to stop the Muslim powers—Ṣavafid Iran and the Ottoman Empire, both near their zenith—from partitioning the country and oppressing its inhabitants. In 1578 the Ottomans overran the whole of Transcaucasia and seized Tbilisi, but they were subsequently driven out by Iran’s Shah ʿAbbās I (reigned 1587–1629), who deported many thousands of the Christian population to distant regions of Iran. There was a period of respite under the viceroys of the house of Mukhran, who governed at Tbilisi under the aegis of the shahs from 1658 until 1723. The most notable Mukhranian ruler was Vakhtang VI, regent of Kartli from 1703 to 1711 and then king, with intervals, until 1723. Vakhtang was an eminent lawgiver and introduced the printing press to Georgia; he had the Georgian annals edited by a commission of scholars. The collapse of the Ṣafavid dynasty in 1722, however, led to a fresh Ottoman invasion of Georgia. The Ottomans were expelled by the Persian conqueror Nādir Shah, who gave Kartli to Tʿeimuraz II (1744–62), one of the Kakhian line of the Bagratids. When Tʿeimuraz died, his son Erekle II reunited the kingdoms of Kartli and Kakheti and made a brave attempt at erecting a Caucasian multinational state based on Georgia. Imereti under King Solomon I (1752–84) succeeded in finally throwing off the domination of the declining Ottoman Empire.
Raids by Lezgian mountaineers from Dagestan, economic stringency, and other difficulties impelled Erekle to adopt a pro-Russian orientation. On July 24, 1783, he concluded with Catherine II (the Great) the Treaty of Georgievsk, whereby Russia guaranteed Georgia’s independence and territorial integrity in return for Erekle’s acceptance of Russian suzerainty. Yet Georgia alone faced the Persian Āghā Moḥammad Khan, first of the Qājār dynasty. Tbilisi was sacked in 1795, and Erekle died in 1798. His invalid son Giorgi XII sought to hand over the kingdom unconditionally into the care of the Russian emperor Paul, but both rulers died before this could be implemented. In 1801 Alexander I reaffirmed Paul’s decision to incorporate Kartli and Kakheti into the Russian Empire. Despite the treaty of 1783, the Bagratid line was deposed and replaced by Russian military governors who deported the surviving members of the royal house and provoked several popular uprisings. Imereti was annexed in 1810, followed by Guria, Mingrelia, Svaneti, and Abkhazia in 1829, 1857, 1858, and 1864, respectively. The Black Sea ports of Potʿi and Batʿumi and areas of southwestern Georgia under Ottoman rule were taken by Russia in successive wars by 1877–78.
