Overview
Demetrius I ( 1093 – 1156), from the Bagrationi dynasty, was King of Georgia from 1125 to 1156. He is also known as a poet. He was King of United Georgian kingdom two times, first in 1125 to 1154 and second in 1155 before his death in 1156.
Life
Demetrius was the eldest son of King David the Builder by his first wife Rusudan. He was brought up in Kutaisi. As a commander, he took part in his father's battles against Seljuks, particularly at Didgori (1121) and Shirvan (1123). In 1117, he was sent by David at the head of a Georgian army into Shirvan, where Demetrius reduced the fortress of Kaladzor (later Alberd, now Ağdaş) and put to flight the men of Sökmen II, "commander of all the forces of Persia" — as a Georgian chronicler suggests. This Sökmen was probably a Shah-Armen prince, and subsequently, ruler in his own right, Sökmen II, whom the Shirvanshah Afridun I must have applied for help. Demetrius succeeded on his father's death on January 24, 1125.
As soon as, he ascended to the throne, the neighbouring Muslim rulers began attacking Georgia from all sides. The Seljuqid sultans fought to restore the rule of the Shirvanshahs. Shirvan's large Muslim population rose against Georgia. This probably happened in 1129 or 1130, when Demetrius restored the Shirvanshahs to power in Shirvan, installing on the throne Manuchihr II, the husband of his daughter Rusudan. The Shirvanshahs had to provide the Georgian king with troops whenever the latter demanded it. In 1130, Georgia was attacked by the Sultan of Ahlat, Shah-Armen Sökmen II ( 1128–1183). This war was started by the passage of Ani into the hands of the Georgians; Demetrius I had to compromise and give up Ani to the Shaddadid emir Fadl ibn Mahmud on terms of vassalage and inviolability of the Christian churches. In 1139, Demetrius raided the city of Ganja in Arran. He brought the iron gate of the defeated city to Georgia and donated it to Gelati Monastery at Kutaisi. Despite this brilliant victory, Demetrius could hold Ganja only for a few years. In reply to this, the sultan of the Eldiguzids attacked Ganja several times, and in 1143 the town again fell to the sultan. According to Mkhitar Gosh, Demetrius ultimately gained possession of Ganja, but, when he gave his daughter in marriage to the sultan, he presented the latter with the town as dowry, and the sultan appointed his own emir to rule it.
