Jahan Shah
Jahan Shah set out from Tabriz with a great army on May 16, 1466, and came to the basin of Lake Van. While there, he was furious to learn that Uzun Hassan was raiding his lands with 12,000 cavalry. Meanwhile, Uzun Hassan, worried 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 mutiny, he decided to withdraw to a winter residence. Uzun Hassan caught his army by surprise and totally defeated them in a sudden attack on October 30 (or November 11), 1467. Jahan Shah was killed while trying to flee, and with his death the great era of Kara Koyunlu history came to an end.
