Demetrius II the Self-Sacrificer or the Devoted (Georgian: დემეტრე II თავდადებული|tr) (1259–12 March 1289) of the Bagrationi dynasty, was king (mepe) of Eastern Georgia reigning from 1270 until his execution by the Mongol Ilkhans in 1289.
Demetrius, born in 1259, was the second son and third child of King David VII of Georgia. His mother was David's third wife Gvantsa née Kakhaberidze. He was 2 years old when Gvantsa was put to death by the Mongols as a reaction to David's abortive rebellion against the Ilkhan hegemony. David himself died in 1270.
Demetrius had an elder half-brother George, an heir apparent, who died before his father's death in 1268, and an elder half-sister Tamar, whom Demetrius subsequently married off, with great reluctance, to a son of the Mongol official Arghun-Agha.
He succeeded on his father's death in 1270, when he was 11 years old. He ruled under the regency of Sadun Mankaberdeli for some time, Sadun was the Atabeg and Amirspasalar, designated by the Mongols. It is for this reason that upon the death of Sadun in 1282, Demetrius refused the post of atabeg to his son Khutlubuga and made him a sworn enemy.
Although he continued to be titled "king of Georgians and Abkhazians, etc", Demetrius's rule extended only over the eastern part of the kingdom. Western Georgia is in the hands of the descendants of David VI Narin who proclaimed themselves kings of western Georgia, and the province of Samtskhe, governed by the independent prince Beka I Jaqeli, is directly subject to the Mongols.
Demetrius also participated in the Mongol campaigns in the Middle East against the Mamluks of Egypt and particularly distinguished himself with Beka I Jaqeli at the head of a Georgian army of 15,000 men under the orders of Möngke Temür, brother of Abaqa Khan, during the Second Battle of Homs in 1281. Despite the defeat of the Mongol troops, the Georgians reported significant spoils.[1]
Demetrius behaved like a loyal subject of Ilkhan; he was a supporter of Tekuder (1282-1284), a Mongol converted to Islam, then of Arghun (1284-1291), brought to the throne in reaction by traditional Mongol Buddhist or Nestorian leaders. He developed friendly relations with the Mongolian nobility. Although he was already married to a Greek princess of Trebizond, he took the Mongolian princess Solghar as his second wife.
In 1288, on the order of Arghun, he subdued the rebel province of Derbent at the Caspian Sea. The same year, Arghun revealed a plot organized by his powerful minister Buqa, whose son was married to Demetrius's daughter. Bugha and his family were massacred, and the Georgian king, suspected to be involved in a plot, was ordered to the Mongol capital, or Arghun threatened to invade Georgia. Despite much advice from nobles, Demetrius headed for the Khan's residence to face apparent death, and was imprisoned there. He was beheaded at Movakan on 12 March 1289. He was buried at Mtskheta, Georgia, and canonized by the Georgian Orthodox Church.
He was succeeded by his cousin Vakhtang II.
