Bagrationi dynasty in the context of "David IV of Georgia"

The Kingdom of Georgia (Georgian: საქართველოს სამეფო, romanized: Sakartvelos samepo), also known as the Georgian Empire, was a medieval Eurasian monarchy that was founded in c. 1008 AD. It reached its Golden Age of political and economic strength during the reign of King David IV and Queen Tamar the Great from the 11th to 13th centuries. Georgia became one of the pre-eminent nations of the Christian East, and its pan-Caucasian empire and network of tributaries stretched from Eastern Europe to Anatolia and northern frontiers of Iran, while Georgia also maintained religious possessions abroad, such as the Monastery of the Cross in Jerusalem and the Monastery of Iviron in Greece. It is the principal historical precursor of present-day Georgia.

Kingdom of Georgia emerged in the early 11th century out of unification of various Georgian kingdoms, most notably the Kingdom of the Iberians and the Kingdom of Abkhazia. Lasting for nearly five centuries, the kingdom fell to the Mongol invasions in the 13th century, but managed to re-assert sovereignty by the 1340s. The following decades were marked by the Black Death, as well as numerous invasions under the leadership of Timur, who devastated the country's economy, population, and urban centers. The Kingdom's geopolitical situation further worsened after the conquest of the Byzantine Empire and the Empire of Trebizond by the Ottoman Turks. As a result of these processes, by the end of the 15th century Georgia turned into a fractured entity. This whole series of events also led to the final collapse of the kingdom into anarchy by 1466 and the mutual recognition of its constituent kingdoms of Kartli, Kakheti, and Imereti as independent states between 1490 and 1493—each led by a rival branch of the Bagrationi dynasty, and into five semi-independent principalities—Odishi, Guria, Abkhazia, Svaneti, and Samtskhe.

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.

Tamar the Great (Georgian: თამარ მეფე, romanized: tamar mepe [ˈt̪ʰämäɾ ˈme̞pʰe̞], lit. 'King Tamar'; c. 1160 – 18 January 1213) reigned as the Queen of Georgia from 1184 to 1213, presiding over the apex of the Georgian Golden Age. A member of the Bagrationi dynasty, her position as the first woman to rule Georgia in her own right was emphasized by the title mepe ("king"), afforded to Tamar in the medieval Georgian sources.

Tamar was proclaimed heir and co-ruler by her reigning father George III in 1178, but she faced significant opposition from the aristocracy upon her ascension to full ruling powers after George's death. Tamar was successful in neutralizing this opposition and embarked on an energetic foreign policy aided by the decline of the hostile Seljuk Turks. Relying on a powerful military elite, Tamar was able to build on the successes of her predecessors to consolidate an empire which dominated the Caucasus until its collapse under the Mongol attacks within two decades after Tamar's death.

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 the Iberians (Georgian: ქართველთა სამეფო, romanized: kartvelta samepo) was a medieval Georgian monarchy under the Bagrationi dynasty which emerged circa 888 AD, succeeding the Principality of Iberia, in historical region of Tao-Klarjeti, or upper Iberia in north-eastern Turkey as well parts of modern southwestern Georgia, that stretched from the Iberian gates in the south and to the Lesser Caucasus in the north.

Historically, the area comprised the following historical districts: West of the Arsiani Mountains were Tao, Klarjeti, Nigali, and Shavsheti, to the east lay Meskheti, Erusheti, Javakheti, Artaani, Abotsi, Kola and Basiani. The landscape is characterised by mountains and the river-systems of the Çoruh and the Kura. The region played a crucial role in the unification of all Georgian lands and principalities into the Kingdom of Georgia in 1008.

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.

The Kingdom of Kakheti (Georgian: კახეთის სამეფო, romanized: k'akhetis samepo; also spelled Kaxet'i or Kakhetia) was a late medieval and early modern monarchy in eastern Georgia, centered at the province of Kakheti, with its capital first at Gremi and then at Telavi. It emerged in the process of a tripartite division of the Kingdom of Georgia in 1466 and existed, with several brief intermissions, until 1762 when Kakheti and the neighboring Georgian kingdom of Kartli were merged through a 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.
