The Battle of Zava was fought on July 18, 1342 between the armies of the Sarbadars and the Kartids. Since their appearance as a political force in Khorasan, the Sarbadars had fought to expand their influence in north-eastern Iran and defend against the forces of the claiming Ilkhan Togha Temür who sought to regain Khorasan. Mu'izz al-Din Husain, the chief of the Kartids of Herat recognized Togha Temur's overlordship, and when the Sarbadars secured their hold on Khorasan they sought to eliminate the Kartid threat to the east.
