Her mother was either Abaqa's wife Maria Palaiologina, an illegitimate daughter of the Byzantine emperor Michael VIII Palaiologos, or Bulujin egechi, a concubine.
[1][2][3] The anonymous 14th-century Chronicle of a Hundred Years, part of the Georgian Chronicles, relates that, after having Demetrius II of Georgia put to death in 1289, the Ilkhan Arghun sent the influential Georgian nobleman Khutlu-Bugha to David I of Imereti, an uncle of the executed monarch, bidding him to send his son Vakhtang, whom he intended to put on the throne of Georgia, and to give him his sister Oljath in marriage.
After the death of her husband, Oljath married, with the consent of the Ilkhan, Vakhtang's cousin and successor, David VIII, a son of Demetrius II.
Oljath was given assurances for the king's safety, as well as the ring and the napkin, the latter being a gage of pardon, while Sibuchi, son of Kutlushah, was offered as a hostage.
[5] No children are reported in the medieval annals from the union of Oljath with David, but a modern hypothesis makes Melchizedek and Andronicus, the 13th-century princes of Alastani, known from the contemporaneous documents, their sons.
