The only non-Toluid army in Iran was at this time under the command of the Chaghadaid prince Tegüder, who had accompanied Hülegü to Iran and received an appanage in Georgia. After Hülegü's death, Tegüder joined the Chaghadaid cause. Trying to join Baraq via Derbend, Tegüder asked to return to his Georgian appanage. King David V refused and Tegüder remained stuck there. David Narin sheltered him in Imereti, but his behavior in Georgia – pillaging villages and caravans and insulting the clergy – provoked the rage of the local population, who urged Abaqa to summon him back. When Tegüder refused (or because he had found out about his plans) Abaqa attacked him, defeating him in 1270, with the help of the Georgian and Armenian troops headed by King David V.
