Abu Sa'id Mirza occupied Herat on July 19, 1457. But he had to immediately abandon the city in order to deal with the Balkh revolt by the sons of Abdal-Latif Mirza, one of whom he killed in battle while the other Juki Mirza escaped to the steppes in the north under the protection of Abul-Khayr Khan, the Khan of the Uzbek principality of Tura, a part of the empire of Desht-i Kipchak region that lies to the east of Ural mountains.[1]
