黑羊王朝
Shahrukh Mirza, fourth ruler of the Timurids, dealt with Kara Koyunlu, who aimed to expand into Iran. But, Jahan Shah (bey of the Kara Koyunlu) drove the Timurids to eastern Iran after 1447 and also briefly occupied Herat in 1458. After the death of Jahan Shah, Uzun Hasan, bey of the Aq Qoyunlu, conquered the holdings of the Kara Qoyunlu in Iran between 1469 and 1471.
