945–958 AD: Continuity in a Time of Change

King Sumbat I ascended the throne in the mid-10th century, ruling for 13 years. He was the son of Adarnase IV, and by the time he became King, he was likely already an elder statesman of the dynasty. His reign serves as a vital bridge connecting the restoration period of his father to the golden age of his nephews.

The Curopalates

Like his predecessors, Sumbat I held the Byzantine title of Curopalates. This title was essentially the seal of approval from the superpower of the day. Sumbat’s reign is notable for the continued stability of the Tao-Klarjeti principality. While the rest of Georgia (Kartli, Kakheti, Hereti) was often embroiled in chaos or Arab raids, Sumbat’s domain remained a safe harbor for Georgian culture.

He is significant for being the father of Bagrat II (the next king) and the grandfather of the unifier Bagrat III. Without Sumbat keeping the line intact and the territory secure, the later unification of Georgia would have been impossible.

The Monastic Boom

Sumbat I ruled during the peak of the “Monastic Colonization” of Tao-Klarjeti. The great lavras founded by St. Grigol Khandzteli a century earlier were now wealthy, powerful institutions. Sumbat patronized these centers, ensuring that the Georgian language and liturgy flourished. The famous Shatberdi Scriptorium was active during his time, copying gospels that are now national treasures.
