Tamar the Great reigned as the Queen of Georgia from 1184 to 1213, presiding over the apex of the Georgian Golden Age. A member of the Bagrationi dynasty, her position as the first woman to rule Georgia in her own right was emphasized by the title mepe, afforded to Tamar in the medieval Georgian sources.
Tamar was proclaimed heir and co-ruler by her reigning father George III in 1178, but she faced significant opposition from the aristocracy upon her ascension to full ruling powers after George's death. Tamar was successful in neutralizing this opposition and embarked on an energetic foreign policy aided by the decline of the hostile Seljuq Turks. Relying on a powerful military élite, Tamar was able to build on the successes of her predecessors to consolidate an empire which dominated the Caucasus until its collapse under the Mongol attacks within two decades after Tamar's death.
Tamar was married twice, her first union being, from 1185 to 1187, to the Rus' prince Yuri, whom she divorced and expelled from the country, defeating his subsequent coup attempts.
