Mirza Aba Bakr's reign was brought to an end in 1514 when Sultan Said Khan invaded Kashgaria. Judging his army to be incapable of putting up an effective resistance, he handed over Yarkand to Jahangir Mirza and promptly headed south for Khotan. Jahangir Mirza, however, having been suddenly thrust into his position with little experience to aid him, decided that maintaining his position in the face of Sultan Said Khan's army would be impossible. Five days after the departure of his father, he destroyed his treasures and allowed the citizens of Yarkand to pillage what they pleased so that it wouldn't fall into the hands of the khan. He then retreated to Sanju in what is modern day Pishan County.
