Кара-Коюнлу
Qara Iskander () ruled the Kara Koyunlu or Black Sheep Turcoman tribe from 1420 to 1436. His struggles with the Timurid ruler Shah Rukh show that he was a brave leader, but he was not able to continue developing what he inherited from his father Qara Yusuf and his reign saw the decline and attenuation of the Kara Koyunlu.
