Jahan Shah
From around 1447 Jahan Shah was involved in a struggle against the Ak Koyunlu who had always been sworn enemies of the Kara Koyunlu. 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.
