High Middle Ages

===Georgia===
{{Main|Georgian Golden Age}}
During the successful reign of King [[David IV of Georgia]] (1089–1125), the [[Kingdom of Georgia]] grew in strength and expelled the [[Seljuk Empire]] from its lands. David's decisive victory in the [[Battle of Didgori]] (1121) against the Seljuk Turks, as a result of which Georgia recaptured its lost capital [[Tbilisi]], marked the beginning of the [[Georgian Golden Age]]. David's granddaughter [[Tamar of Georgia|Queen Tamar]] continued the upward rise, successfully neutralizing internal opposition and embarking on an energetic foreign policy aided by further decline of the hostile [[Seljuk Empire|Seljuk Turks]]. Relying on a powerful military élite, Tamar was able to build on the successes of her predecessors to consolidate an empire which dominated vast lands spanning from present-day southern [[Russian Federation|Russia]] on the [[Black Sea]] to the [[Caspian Sea]]. Georgia remained a leading regional power until its collapse under the [[Mongol Empire|Mongol]] attacks within two decades after Tamar's death.
