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. David soon raised a rebellion against the Mongol hegemony and entrenched himself in the mountains of
Mtiuleti. In 1298, Oljath was part of the delegation sent by David for negotiations with the Mongol commander
Kutlushah, who treated the queen with special honor, she being a Mongol princess. 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. The queen, however, was detained and, after David refused to arrive at negotiations in person, carried off to
Iran. The Ilkhan determined that she should not again return to her husband. When David learned this, he, in 1302, married the daughter of
Hamada Surameli. 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. == Third marriage ==
