Seljuk Sultanate of Rum. Kaykhusraw II (1237–1246 AD). Dirham (Silver, 24 mm, 2.9 g). Obv: السلطان / الأعظم / كيخسرو بن / كيقباد — “The Supreme Sultan, Kaykhusraw, son of Kayqubad.” Rev: الإمام / المستنصر / بالله أمير / المؤمنين — “The Imam al-Mustansir bi’llah, Commander of the Faithful.” Reference: Album, Checklist of Islamic Coins, 1216.1. Kaykhusraw II ruled the Seljuk Sultanate of Rum during a period of growing internal unrest and Mongol pressure. His reign was shaken by the Babai revolt and, in 1243, the Seljuk army was decisively defeated by the Mongols at Köse Dağ. Afterward, the sultanate became increasingly dependent on the Mongol Ilkhanate, marking the beginning of its political decline despite continued prosperity in Anatolian trade and culture.
