Ascends the throne in 1089; reforms of army, church and state open the Golden Age.
1089
David IV the Builder (Aghmashenebeli, r. 1089–1125) was Georgia's greatest king, under whom the country expelled the Seljuks and became the strongest power in the Caucasus.
He reformed the army and the church (the Ruisi-Urbnisi council), formed a guard of Kipchaks, retook Tbilisi and made it his capital, and founded the Gelati academy.
The victory at Didgori (1121) and the unification of the Georgian lands opened the golden age; David is venerated as a saint.
