Qara Yusuf died during the first of the campaigns in November 1420, which ended in the Timurid capture of Azerbaijan and Armenia. However, less than a year later Shah Rukh was forced to face off a rebellion by the late Turkoman prince's sons. One of these sons, Qara Iskander, continued his attempts to reassert Turkoman authority over the following years, necessitating the second campaign in 1429. This too resulted in a Timurid victory and the installation of a Qara Qoyunlu prince, Abu Said, as a puppet ruler. However, Qara Iskander reoccupied the city of Tabriz two years later and had Abu Said executed.
