Kartli in the context of Tbilisi

In Greco-Roman geography, Iberia (Ancient Greek: Ἰβηρία Iberia; Latin: Hiberia; Parthian: wurğān; Middle Persian: wiručān) was an exonym for the Georgian kingdom of Kartli or Iveria (Georgian: ქართლის სამეფო or ივერიის სამეფო), known after its core province. The kingdom existed during Classical Antiquity and the Early Middle Ages, either as an independent state or as a dependent of larger empires, notably the Sassanid and Roman empires. Iberia, centered on present-day eastern Georgia, was bordered by Colchis in the west, Caucasian Albania in the east and Armenia in the south.

Its population, the Iberians (Iverians), formed the nucleus of the Kartvelians (i.e., Georgians). Iberia, ruled by the Pharnavazid, Artaxiad, Arsacid and Chosroid royal dynasties, together with Colchis to its west, would form the nucleus of the unified medieval Kingdom of Georgia under the Bagrationi dynasty.

The Christianization of Iberia (Georgian: ქართლის გაქრისტიანება, romanized: kartlis gakrist'ianeba) refers to the spread of Christianity in the early 4th century as a result of the preaching of Saint Nino in the ancient Georgian kingdom of Kartli, known as Iberia in classical antiquity. The then-pagan king of Iberia Mirian III declared Christianity to be the kingdom's state religion. According to Roman historian Sozomen, this led the king's "large and warlike barbarian nation to confess Christ and renounce the religion of their fathers", as the polytheistic Georgians had long-established anthropomorphic idols, known as the "Gods of Kartli". The king would become the main sponsor, architect, initiator and an organizing power of all building processes.

Per Socrates of Constantinople, the "Iberians first embraced the Christian faith" alongside the Abyssinians, present day Ethiopians but the exact date of the event is still debated. The kings of Georgia and Armenia were among the first monarchs anywhere in the world to convert to the Christian faith. Prior to the escalation of the Armeno-Georgian ecclesiastical rivalry and the Christological controversies, their Caucasian Christianity was extraordinarily inclusive, pluralistic and flexible that only saw the rigid ecclesiological hierarchies established much later, particularly as "national" churches crystallised from the 6th century. Despite the tremendous diversity of the region, the Christianization process was a pan-regional and a cross-cultural phenomenon in the Caucasus, Eurasia's most energetic and cosmopolitan zones throughout the late antiquity, hard enough to place Georgians and Armenians unequivocally within any one major civilization.

The Bagratuni or Bagratid dynasty (Armenian: Բագրատունի, Armenian pronunciation: [bagɾatuni]) was an Armenian royal dynasty which ruled the medieval Kingdom of Armenia from c. 885 until 1045. Originating as vassals of the Kingdom of Armenia of antiquity, they rose to become the most prominent Armenian noble family during the period of Arab rule in Armenia, eventually establishing their own independent kingdom. Their domain included regions of Armenia such as Shirak, Bagrevand, Kogovit, Syunik, Lori, Vaspurakan, Vanand and Taron. Many historians, such as Cyril Toumanoff, Nicholas Adontz and Ronald Suny, consider them to be the progenitors of the Georgian royal Bagrationi dynasty.

The Kingdom of Kartli (Georgian: ქართლის სამეფო, romanized: kartlis samepo) was a late medieval and early modern monarchy in eastern Georgia, centred on the province of Kartli, with its capital at Tbilisi. It emerged in the process of a tripartite division of the Kingdom of Georgia in 1478 and existed, with several brief intervals, until 1762 when Kartli and the neighbouring Georgian kingdom of Kakheti were merged through dynastic succession under the Kakhetian branch of the Bagrationi dynasty. Through much of this period, the kingdom was a vassal of the successive dynasties of Iran, and to a much shorter period Ottoman Empire, but enjoyed intermittent periods of greater independence, especially after 1747.

Vakhtang I Gorgasali (Georgian: ვახტანგ I გორგასალი, romanized: vakht'ang I gorgasali; c. 439 or 443 – 502 or 522), of the Chosroid dynasty, was a king (mepe) of Iberia, natively known as Kartli (eastern Georgia) in the second half of the 5th and first quarter of the 6th century.

He led his people, through an ill-fated alliance with the Byzantine Empire, into a lengthy struggle against Sasanian Iranian hegemony, which ended in Vakhtang's defeat and weakened the kingdom of Iberia. Tradition also ascribes to him the reorganization of the Georgian Orthodox Church and the foundation of Tbilisi, Georgia's modern capital.

The Pharnavazid (Georgian: ფარნავაზიანი, romanized: parnavaziani) is the name of the first dynasty of Georgian kings of Kartli (Iberia) preserved by The Georgian Chronicles. Their rule lasted, with intermissions, from the 3rd century BC to the 2nd century AD. The main male line is reported to have become extinct early on and followed by houses related to it in the female line. By the close of the 2nd century AD, the Pharnavazid rule came to an end and the Arsacid dynasty took over the crown of Iberia.

The Arsacid dynasty or Arshakiani (Georgian: არშაკიანი, romanized: arshak'iani), a branch of the Arsacid dynasty of Parthia, ruled the ancient Kingdom of Iberia (Kartli, eastern Georgia) from c. 189 until 284 AD. The Arsacid dynasty of Iberia was succeeded by the Chosroid dynasty.

Mirian III (Georgian: მირიან III) was a king (mepe) of Iberia or Kartli (Georgia), contemporaneous to the Roman emperor Constantine the Great (r. 306–337). He was the founder of the royal Chosroid dynasty.

According to the early Medieval Georgian annals and hagiography, Mirian was the first Christian king of Iberia, converted through the ministry of Nino, a Cappadocian female missionary. Following the Christianization of Iberia, he is credited with having established Christianity as his kingdom's state religion and is regarded by the Georgian Orthodox Church as a saint and was canonized as Saint Equal to the Apostles King Mirian (Georgian: წმინდა მოციქულთასწორი მეფე მირიანი).

Georgia is one of the oldest wine-producing countries in the world. The fertile valleys and protective slopes of the South Caucasus were home to grapevine cultivation and neolithic wine production (Georgian: ღვინო, ɣvino) for at least 8000 years. Due to millennia of winemaking and the prominent economic role it retains in Georgia to the present day, wine and viticulture are entwined with Georgia's national identity.

In 2013, UNESCO added the ancient traditional Georgian winemaking method using the Kvevri clay jars to the UNESCO Intangible Cultural Heritage Lists. The best-known Georgian wine regions are in the country's east, such as Kakheti (further divided into the micro-regions of Telavi and Kvareli) and Kartli, but also in Imereti, Racha-Lechkhumi and Kvemo Svaneti, and coastal areas like Adjara and Abkhazia.

Bacurius (Georgian: ბაკურ, romanized: bak'ur) was a Roman general of Georgian origin and a member of the royal family of Iberia (Kartli, eastern Georgia) mentioned by several Greco-Roman authors of the 4th and 5th centuries. It is accepted, but not universally, that all these refer to the same person, an Iberian "king" or "prince", who joined the Roman military ranks. Scholarly opinion is divided whether Bacurius can be identified with one of the kings named Bacurius the Great (Georgian: ბაკურ დიდი, romanized: bak'ur didi), attested in medieval Georgian annals, who might have taken refuge in territories obtained by the Eastern Roman Empire during the Roman–Persian Wars that were fought over the Caucasus.

The oldest Georgian Bir el Qutt inscriptions mention Bacurius. He is also thought to be a possible maternal great-uncle or grandfather of Peter the Iberian.

Shida Kartli (Georgian: შიდა ქართლი, IPA: [ʃida kʰaɾtʰli]; lit. 'Inner Kartli') is a landlocked administrative region (mkhare) in eastern Georgia. It comprises a central part of the historical-geographic province of Shida Kartli. With an area of 5,729 square kilometres (2,212 sq mi), Shida Kartli is the 8th largest Georgian region by land area. With 284,081 inhabitants, it is Georgia's seventh-most-populous region. Shida Kartli's capital and largest city, Gori, is the 5th largest city in Georgia.

The region is bordered by Russia to the north, Georgian regions of Mtskheta-Mtianeti to the east, Kvemo Kartli to the south, Samtskhe-Javakheti to the southwest, Imereti to the west, and Racha-Lechkhumi and Kvemo Svaneti to the northwest. It consists of the following municipalities: Gori, Kaspi, Kareli, Java, Khashuri.

Principality of Iberia (Georgian: ქართლის საერისმთავრო, kartlis saerismtavro) was an early medieval aristocratic regime in a core Georgian region of Kartli, called Iberia by classical authors. It flourished in the period of interregnum between the sixth and ninth centuries, when the leading political authority was exercised by a succession of princes. The principality was established shortly after the Sassanid suppression of the local royal Chosroid dynasty, around 580; it lasted until 888, when the kingship was restored by a member of the Bagrationi dynasty. Its borders fluctuated greatly as the presiding princes of Iberia confronted the Persians, Byzantines, Khazars, Arabs, and neighboring Caucasian rulers throughout this period.

The time of the principate was climacteric in the history of Georgia; the principality saw the final formation of the Georgian Christian Church, the first flourishing of a literary tradition in the native language, the rise of the Georgian Bagratid family, and the beginning of cultural and political unification of various feudal enclaves, which would be united to form the Kingdom of Georgia by the early 11th century.

Tao-Klarjeti (Georgian: ტაო-კლარჯეთი, romanized: t'ao-k'larjeti [tʼäo̞kʼɫäɾd͡ʒe̞t̪ʰi]) is a Georgian historical and cultural region in north-eastern Turkey. The region is based around two river basins - Chorokhi and Kura (Mtkvari), and also partially includes the upper source of the Aras river. In modern usage it most often denotes the territory that was administered or claimed by Georgian Democratic Republic but is nowadays part of Turkey due to the Soviet-Turkish deal in 1921.

The term "Tao-Klarjeti" is based on the names of two most important provinces of the region — Tao and Klarjeti. The term is equivalent to “Zemo Kartli” (i.e., Upper Kartli or Upper Iberia) and is also a synonym for historical Meskheti.

Zemo Kartli (Georgian: ზემო ქართლი; lit. Upper Kartli or Upper Iberia) is a historical region in south-western Georgia, comprising the lands in the upper basin of the Kura River (from origins of Kura River to Tashiskari) and Chorokhi River basin, making it subregion of greater Kartli. Until 16th century, Zemo Kartli included: Samtskhe, Javakheti, Erusheti, Artaani, Kola, Klarjeti, Shavsheti, Tao and Speri.

Eastern Georgia (Georgian: აღმოსავლეთ საქართველო, aghmosavlet' sak'art'velo) is a geographic area encompassing the territory of the Caucasian nation of Georgia to the east and south of the Likhi and Meskheti Ranges, but excluding the Black Sea region of Adjara.

Eastern Georgia includes the historic Georgian provinces of Samtskhe, Javakheti, Kartli with the national capital city of Tbilisi, Kakheti, Pshavi, Mtiuleti, Tusheti, Khevsureti, and Khevi. Current administrative regions (mkhare) of eastern Georgia are: Samtskhe-Javakheti, Shida Kartli, Kvemo Kartli, the city of Tbilisi, Mtskheta-Mtianeti, and Kakheti.

Adarnase IV (Georgian: ადარნასე IV) (died 923), or Adarnase II, was a Georgian monarch of the Bagrationi dynasty who reigned in the late 9th and early 10th centuries. The son of the Kouropalates David I of Iberia, he ruled as duke of Lower Tao from 881 to 923, king (mepe) of the Kingdom of the Iberians from 888 to 923 and Kouropalates of Iberia from 891 to 923, re-establishing the Georgian monarchy in 888, more than three centuries after the abolition of the Kingdom of Iberia by Sasanian Empire.

He succeeded his father to the duchy of Lower Tao, a border march between Byzantine Empire and Caucasus, when the latter was assassinated by Nasra of Tao-Klarjeti in 881. When the latter led a Byzantine invasion force to invade the Caucasus, Adarnase defeated him in 888 and became the first sovereign to take the title of ‘King of the Iberians’, to signal his independence from the Byzantine Empire. With the help of neighbouring Armenia, he consolidated his power and gained control over Kartli, as well as Byzantine recognition in 891 after killing Gurgen I of Tao. The reign of Adarnase IV was marked by a change in Georgia's political orientation, as it left the Byzantine sphere of influence to join Armenia and, by extension, a declining Abbasid caliphate. The king often became involved in Armenia's internal affairs and helped King Smbat I of Armenia to consolidate his own power.
