George II continued the expansionist policy of his predecessor, aiming primarily at unification of Georgia.

However, Bagrat, George's youngest brother, also claimed the crown, the latter engineered a coup with the support of a party of nobles, most importantly his father-in-law, Gurgen II of Tao (r. 918–941).

To secure the allegiance of the local nobility in central Georgia, George appointed his son Constantine as a duke/viceroy of Kartli in 923, but the latter too, revolted against him in 926.

[2] To secure his supremacy over Kartli, George allied himself with the Georgian Bagratids of Tao-Klarjeti, and gave his daughter, Gurandukht to Gurgen Bagrationi in marriage.

The Georgian Chronicles describes him: “He had all the virtues, courage and boldness; was faithful to God, was famous as the builder of the churches, merciful towards the poor, generous, modest, full of noble features and kind”.
