Kaykhusraw was killed at the Battle of Antioch on the Meander in 1211. His son Kayqubad I, by Manuel Maurozomes' daughter, ruled the Sultanate from 1220 to 1237, and his grandson, Kaykhusraw II, ruled from 1237 to 1246. Kaykhusraw's body was taken to Konya, where it was buried in the ancestral tomb of his family.
