Uzun Hasan had recently gained ascendancy after defeating his rival claimants to the throne in eastern Anatolia at Diyarbakir. He faced threats from the Ottoman Sultanate and the Kara Koyunlu and in wide ranging campaigns against them gained a reputation as a fierce fighter. Jahan Shah was eventually defeated by Uzun Hasan in the Battle of Chapakchur near the Sanjak of Çapakçur[3][4] in present-day eastern Turkey on October 30[5] (or November 11[6]), 1467.
