Alvand Mirza was appointed to rule
Mosul during his uncle
Jahan Shah's reign. Mirza rebelled against the latter and was forced to flee to the
Aq Qoyunlu, then under the rule of Jahangir Beg. Jahan Shah demanded that his rebellious nephew be handed over to him, but Jahangir Beg refused. Jahan Shah then invaded
Erzincan and sent his grandnephew, Rustem Beg, to subdue Jahangir Beg. Hopelessly, Jahangir Beg sent his mother
Sara Khatun to
Mamluk Egypt, while Jahan Shah started to support his half-brother Sheikh Hasan. Sheikh Hasan was killed by
Uzun Hasan, brother of Jahangir Beg; Jahan Shah quickly offered peace to Aq Qoyunlu, in return for accepting their submission. Jahangir Beg accepted and also wed his daughter to Jahan Shah's son Mirza Muhammad. == In Timurid service ==
