George VIII

George VIII, born in 1417, was a significant figure in Georgian history, ruling the Kingdom of Georgia from 1446 to 1465 and later the Kingdom of Kakheti as George I until his death in 1476. As a member of the Bagrationi dynasty, he was the third son of Alexander I of Georgia. In 1433, his father appointed him as co-ruler alongside his brothers in a bid to consolidate royal authority against the rising power of the nobility.

However, George's early reign was marked by the influence of the nobles, which ultimately led to his father's abdication in 1442. Following this, he took administrative control of the northeastern territories of the Caucasus under the guidance of his elder brother, Vakhtang IV. Upon Vakhtang's death in 1446, George seized the throne, disinheriting his brother Demetrius and forcing him into exile.

George VIII is often remembered as the last monarch to preside over a united Georgian kingdom, although the formal division of the realm did not occur until 1490. His reign saw the loss of control over Samtskhe in the 1460s, when the atabeg Qvarqvare II Jaqeli declared independence. The Georgian Triumvirate War further fragmented the kingdom, leading to George's capture and imprisonment in 1465 by the atabeg of Samtskhe, which significantly weakened royal power.

After his release in 1466, George established control over Kakheti, declaring it an independent kingdom and ruling peacefully until his death. His reign laid the groundwork for the early institutions of Kakheti. On the international front, George VIII witnessed significant geopolitical changes, including the fall of Constantinople in 1453 and Trebizond in 1461, yet he chose not to intervene against the Ottoman Empire despite appeals for assistance from the Byzantines.
