The Qara Qoyunlus become a great empire during the rule of Gara Yusif.  In a battle against the Timurids and Jalairis, Qara Yusif created a large state from Azerbaijan. This united Eastern Georgia, Arab Iraq and Ajam Iraq. Qara Iskander, the son of Qara Yusif, restored the rule of Kara Koyunlu in 1421.
