Kayqubad I, Seljuk Sultan of Rum
r. 1220-1237/616-634 AH
Ala al-Din Kaykubad I was one of the most influential rulers among the Seljuks of Rum, the Turkic dynasty that ruled over parts of Anatolia in the late eleventh and twelfth centuries. 

Kayqubad I's reputation came mostly from his victories in foreign policy and the expansion of the empire within the Anatolian peninsula, especially significant was the annexation of the southern Mediterranean shore around the Byzantine port city of Kalon-Oros, which he renamed Ala'iyya (modern day Alanya). He is also known for founding the palace cities of Kaykubadabad and Kaykubadiyya, as well as being a patron of other constructions.
