Principality of Mingrelia in the context of "Odishi"

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.

Bagrat III (Georgian: ბაგრატ III; born 23 September 1495 – died 1565), of the Bagrationi dynasty, was the King (mepe) of Imereti from 1510 to 1565, one of the three Georgian kingdoms that shared control over Georgia following its division in 1490.

Bagrat ascended the throne at the age of fifteen after the death of his father. Throughout his reign, he faced numerous invasions by the Ottoman Empire, notably in 1512, 1543, 1545, and 1549. These invasions led to widespread devastation across his realm and marked the beginning of the decline of a once-powerful western Georgian kingdom. Although Bagrat initially controlled extensive territories, he gradually lost authority over Abkhazia, Samtskhe, and, toward the end of his reign, over the strong principalities of Guria and Mingrelia. His struggles against rebellious vassals proved fruitless, and by the time of his death, after fifty-five years of rule, his dominion had been reduced to the capital city of Kutaisi and a few surrounding agricultural provinces.

The House of Dadiani (Georgian: დადიანი [dadiani]), later known as the House of Dadiani-Chikovani, was a Georgian family of nobles, dukes and princes, and a ruling dynasty of the western Georgian province of Mingrelia.
