Fearing that her nephew David VII Ulu would claim the throne at her death, Rusudan held the latter prisoner at the court of her son-in-law, the sultan Kaykhusraw II, and sent her son David to the Mongol court to get official recognition as heir apparent.
Finally, Güyük Khan recognized David (Lasha Giorgi’s son) as senior joint sovereign and appointed another David (Rusudan’s son) junior co-ruler.
The consort of Queen Rusudan was a younger son of 'Abdu'l Harij Muhammad Mughis ad-din Tughril Shah, the Seljuq emir of Erzurum, and his wife, a daughter of Sayf al-Din Begtimur, the ruler of Ahlat.
Rusudan made an alliance with the neighbouring Seljuk rulers of Rüm and Ahlat, but the Georgians were routed by the Khwarezmians at Bolnisi, before the allies could arrive (1228).
