His reign, and that of Tamar, are seen as the Georgian Golden Age - the era of empire, diplomatic success, military triumphs, great learning, cultural, spiritual, and artistic flowering. With his ascent to the throne, Giorgi III launched a successful campaign against the Seljuk sultanate of Ahlat (the Shah-Armen State) in 1156. Giorgi took and annexed the Armenian cities of Ani and Dvin in 1161–1162.
The city was finally incorporated into the Georgian Kingdom in 1173.
