Kayqubad II (Old Anatolian Turkish: كیقباد; Persian: علاء الدين كيقباد بن كيخسرو, ʿAlāʾ ad-Dīn Kayqubād bin Kaykhusraw, c. 1238-1239 – 1254/1256) was the Seljuk Sultan of Rûm from 1249-1257. He was the only son of the Seljuq Sultan of Rûm Kaykhusraw II and the Georgian princess Gurju Khatun (known as Tamar). Kaykhusraw's elder sons, by different mothers, were Kaykaus II and Kilij 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]
