When Timur's successor Shah Rukh reconquered the region in 1421, Izz al-Din Shir was among the nobles and dignitaries who visited him in his winter quarters in Qarabagh to offer their fealty. Malik Muhammad did the same soon after when the conqueror visited the Lake Van region. When Qara Yusuf's son Qara Iskander temporarily regained control of the area, Shir refused to recognise his rule, a policy followed by his successors.[14] Izz al-Din Shir died two years later, in 1423.[15]
