Kaykaus II or Kayka’us II (Persian: عز الدين كيكاوس بن كيخسرو ʿIzz ad-Dīn Kaykāwūs bin Kaykhusraw) was the eldest of three sons of Kaykhusraw II. He was a youth at the time of his father’s death in 1246 and could do little to prevent the Mongol conquest of Anatolia. For most of his tenure as the Seljuq Sultan of Rûm he shared the throne with one or both of his brothers Kilij Arslan IV and Kayqubad II.
