His mother was of Byzantine ancestry; Christian Greek women were the dominant origin of the slave-concubines in the Seljuk harem.

[3] Kaykhusraw received a good education during his upbringing, learning other languages besides his native Turkish, which was Persian, Arabic, and Greek.

[7] With his brother, Rukn ad-Din Suleiman Shah, quickly advancing towards Konya, Kaykhusraw fled to Constantinople in 1196.

[9] A mathnawi written by Kaykhusraw himself compares his destiny during that period to that of the legendary Iranian hero Jam (Jamshid), who had to go into exile after losing his divine fortune (farr).

[4] Muhammad ibn Ali Rawandi (died after 1207) dedicated his historical chronicle of the Seljuk Empire, Rahat al-sudur wa-ayat al-surur, to Kaykhusraw.
