Ulugh Beg
Meanwhile, circumstances in Samarkand became serious while Ulugh Beg was away. The leader of the Uzbeks, Abul-Khayr Khan, had invaded Transoxiana and raided the suburbs of Samarkand. Ulugh Beg was at that time chasing after Ala al-Dawla Mirza and had reached Bistam and Pul-e-Ibrahim. With this invasion Ulugh Beg had no time to consolidate his control over Khurasan and he left for his beloved city of Samarkand with the body of Shahrukh Mirza leaving Abdal-Latif Mirza in charge of Herat.
