George V the Brilliant in the context of "Samtskhe-Saatabago"

The Kingdom of Imereti (Georgian: იმერეთის სამეფო, romanized: imeretis samepo) was a Georgian monarchy established in 1463 by a member of the house of Bagrationi when the Kingdom of Georgia was dissolved into rival kingdoms. Before that time, Imereti was considered a separate kingdom within the Kingdom of Georgia, of which a cadet branch of the Bagrationi royal family held the crown.

The realm was conquered by George V the Brilliant and once again united with the east Kingdom of Georgia. From 1463 onward, however, Imereti became a constant battleground between Georgian and Ottoman forces for several centuries, resulting in the kingdom's progressive decline due to this ongoing instability. These threats pushed local Georgian rulers to seek closer ties with Tsardom of Russia. In 1649, Imereti sent ambassadors to the Russian royal court and Russia returned favor in 1651. In the presence of Russian ambassadors, Alexander III of Imereti swore an oath of allegiance to Tsar Alexis of Russia. However, internal conflicts among Georgian royalty continued and, although Alexander III briefly managed to control all of Western Georgia, this consolidation was short lived. By the time of his death in 1660, Western Georgia was still in a state of flux. In this chaotic period, Archil of Imereti was enthroned and deposed several times. His efforts to secure assistance from Russia and, later, Pope Innocent XII proved unsuccessful and he was finally exiled to Russia.
