George III (გიორგი III) (died 27 March 1184), of the Bagrationi dynasty, was the 8th King of Georgia from 1156 to 1184. He became king when his father, Demetrius I, died in 1156, which was preceded by his brother's revolt against their father in 1154. His reign was part of what would be called the Georgian Golden Age – a historical period in the High Middle Ages, during which the Kingdom of Georgia reached the peak of its military power and development. George was the father of Queen Tamar the Great. He succeeded on his father Demetrius I's death in 1156. He changed his father's defensive policy into a more aggressive one and resumed offensive against the neighboring Seljuqid rulers in Armenia. The same year he ascended to the throne, George launched a successful campaign against the Shah-Armens. It may be said that the Shah-Armen took part in almost all the campaigns undertaken against Georgia between 1130s to 1160s. Moreover, Shah-Armens enlisted the assistance of Georgian feudals disaffected with the Georgian monarchs and gave them asylum. In 1156 the Ani's Christian population rose against the emir Fakr al-Din Shaddad, a vassal of George III, and turned the town over to his brother Fadl ibn Mahmud. But Fadl, too, apparently could not satisfy the people of Ani, and this time the town was offered to the George III, who took advantage of this offer and subjugated Ani, appointing his general Ivane Orbeli as its ruler in 1161. A coalition consisting of the ruler of Ahlat, Shah-Armen Sökmen II, the ruler of Diyarbekir, Kotb ad-Din il-Ghazi, Al-Malik of Erzerum, and others was formed as soon as the Georgians seized the town, but the latter defeated the allies. He then marched against one of the members of the coalition, the king of Erzerum, and in the same year, 1161, defeated and made him prisoner, but then released him for a large ransom. The capture of Ani and the defeat of the Saltukid-forces enabled the Georgian king to march on Dvin.
