Jahan Shah
Towards the end of 1467, Abu Sa'id received word of the death of Jahan Shah at the hands of Uzun Hasan, the ruler of the Aq Qoyunlu, a kingdom which had previously been the traditional allies of the Timurids. Abu Sa'id, in spite of his warm relations with Jahan Shah, had never truly abandoned hopes of recapturing the western territories which had previously been conquered by the Qara Qoyunlu. Seeing these lands now being absorbed by the Aq Qoyunlu, Abu Sa'id was aware that any chance of reclaiming them was unlikely if Uzun Hasan's rise was not checked. Therefore, under the pretext of responding to Jahan Shah's son Hasan Ali's appeal for aid, Abu Sa'id launched a campaign against the Aq Qoyunlu in February 1468.
