Timur appears not to have had particularly close relations with Shah Rukh, despite the latter never having incurred his displeasure. In 1397, Shah Rukh was appointed governor of Khorasan by his father, with his viceregal capital being Herat. Although this was a significant region, this was also the same post that had been awarded to Shah Rukh's brother Miran Shah when the latter had been thirteen years old. Shah Rukh was never promoted beyond this position during his father's lifetime. Further to this, during Timur's campaign to China, Shah Rukh's young sons took pride of place in the procession while he himself was passed over.
