Conflict with Jahangir From around 1447 Jahan Shah was involved in a struggle against the
Ak Koyunlu who had always been sworn enemies of the Qara Qoyunlu. First of these battles happened when Alvand Mirza rebelled and fled to
Jahangir, chief of Ak Koyunlu. Jahan Shah demanded his rebellious nephew, but Jahangir refused to hand him over. Jahan Shah invaded
Erzincan and sent his commander – Rustem beg to subdue Jahangir. Hopeless Jahangir sent his mother
Sara Khatun to Mamluk Egypt while Jahan Shah started to support his half-brother Sheikh Hasan. While Sheikh Hasan was killed by
Uzun Hasan, brother of Jahangir; Jahan Shah hasted to offer peace to
Ak Koyunlu, in return to accept their submission. Jahangir accepted and also wed his daughter to
Mirza Muhammad.
Conflict with Uzun Hasan Uzun Hasan did not acknowledge his elder brother's submission and rebelled against him, capturing
Amid in 1457. Jahangir fled to Jahan Shah. Uzun Hasan was also supported by
Safavids, their leader
Shaykh Junayd being brother-in-law to Uzun Hasan. He was replaced by
Shaykh Jafar – his uncle. 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 Qara Qoyunlu 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. ==Legacy==
