Kayqubad II (Old Anatolian Turkish:كیقباد;Persian:علاء الدين كيقباد بن كيخسرو,ʿAlāʾ ad-Dīn Kayqubād bin Kaykhusraw,c. 1238-1239 – 1254/1256) was theSeljuk Sultan of Rûm from 1249-1257. He was the only son of the Seljuq Sultan of RûmKaykhusraw II and theGeorgian princessGurju Khatun (known as Tamar). Kaykhusraw's elder sons, by different mothers, wereKaykaus II andKilij Arslan IV, and also served as sultan after their father's death, often simultaneously. As son of the sultan’s favorite wife, he was designated heir. He had a weak constitution and was likely seven years old at the time of his father’s death in 1246.[2]
The vizier to the sultan,Shams al-Din Isfahani, seeking to defend a degree of Seljuk sovereignty inAnatolia from theMongols, put Kayqubad II on the throne together with his two elder brothers, Kaykaus II and Kilij Arslan IV.
In 1254 the Mongols asked that Kaykaus II, then nineteen years old, come in person toMöngke, theGreat Khan. The brothers, at a conference inKayseri, decided that Kayqubad II should go to in his stead. The voyage to Möngke’s capital atKarakhorum would be arduous. Kayqubad delayed his trip until at least 1256. He witnessedBayju assembling his horsemen for the migration toAnatolia and sent messages advising his brothers to comply with the Mongol’s demands. One day on the road Kayqubad was found dead. Thevizier Baba Tughra’i, who had joined the embassy en route, was accused but nothing came of it. Kayqubad was buried somewhere in the wastes betweenAnatolia andMongolia.[3]
