Jahan Shah
Jahan Shah set out from Tabriz with a great army on 16 May 1466, and came to the basin of Lake Van. While there, he was furious to learn that Uzun Hasan was raiding his lands with 12,000 cavalry. Meanwhile, Uzun Hasan, suspecting that Jahan Shah was planning to attack him, had carefully guarded the mountain passes. Envoys went back and forth between them, but because of Jahan Shah’s heavy demands, an agreement could not be reached. Having advanced as far as Muş, Jahan Shah had to postpone his attack because of the onset of winter. As his troops began to complain, he decided to withdraw to a winter residence. Uzun Hasan caught his army by surprise and totally defeated them in a sudden attack. Mirza Yusuf and Mirza Muhammad was captured on 30 October or 11 November 1467 at the Battle of Chapakchur. Jahan Shah was killed in battle while fleeing. and with his death the great era of Kara Koyunlu history came to an end. He was succeeded by his son Hasan Ali. Jahan Shah had been buried in southern part of Blue Mosque, Tabriz.
