Kingdom of Iberia in the context of "Saint Nino"

Georgia is a country in the Caucasus region on the coast of the Black Sea. It is located at the intersection of Eastern Europe and West Asia, and is today generally regarded as part of Europe. It is bordered to the north and northeast by Russia, to the south by Turkey and Armenia, and to the southeast by Azerbaijan. Georgia covers an area of 69,700 square kilometres (26,900 sq mi). It has a population of 3.9 million, of which over a third live in the capital and largest city, Tbilisi. Ethnic Georgians, who are native to the region, constitute a majority of the country's population and are its titular nation.

Georgia has been inhabited since prehistory, hosting the world's earliest known sites of winemaking, gold mining, and textiles. The classical era saw the emergence of several kingdoms, such as Colchis and Iberia, that formed the nucleus of the modern Georgian state. In the early fourth century, Georgians officially adopted Christianity, which contributed to their unification under the Kingdom of Georgia. Georgia reached its Golden Age during the High Middle Ages under the reigns of King David IV and Queen Tamar. Beginning in the 15th century, the kingdom declined and disintegrated due to internal discord and pressure from various regional powers, including the Mongols, the Ottoman Empire, and Persia, before being gradually annexed into the Russian Empire starting in 1801.

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 unification of the Georgian realm (Georgian: ქართული სახელმწიფოს გაერთიანება, romanized: kartuli sakhelmts'ipos gaertianeba) was the 10th-century political movement that resulted in the consolidation of various Georgian crowns into a single realm with centralized government in 1008, the Kingdom of Georgia, or Sakartvelo. It was originally initiated by the powerful local aristocracy of the eristavs, due to centuries-long power struggles and aggressive wars of succession between the Georgian monarchs, arising from their independent ruling traditions of classical antiquity and their Hellenistic-era monarchical establishments in Colchis and Iberia.

The initiative was supported by David III the Great of the Bagrationi dynasty, the most powerful ruler in the Caucasus at the time, who would put prince royal Bagrat, his kin and foster-son, on the Iberian throne, who would eventually be crowned King of all-Georgia. David's Bagratid successors would become the champions of national unification, just like the Rurikids or the Capetians, but despite their enthusiasm, some of the Georgian polities that had been targeted for unification did not join the unification freely and would actively fight against it throughout this process, mostly seeking help and support from the Byzantine Empire and the Abbasid Caliphate. Even though the 1008 unification of the realm would unite most of western and central Georgian lands, the process would continue to the east, and eventually reach its total completion under King David IV the Builder. This unprecedented political unification of lands and the meteoric rise of Bagrationi power would inaugurate the Georgian Golden Age and creation of the only medieval pan-Caucasian empire, attaining its greatest geographical extent and dominating the entire Caucasus in the 11th, 12th and 13th centuries.

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 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.

Moschia (Meskheti, possibly related to Mushki) is a mountainous region of Georgia between Iberia, Armenia, and Colchis. The Moschian Mountains were the connecting chain between the Caucasus and Anti-Taurus Mountains. The people of that area were known as the Moschi. They may have been connected to the Mushki.

Wilhelm Gesenius suggested that the Moschi were descended from the Biblical Meshech tribe.
