wife of Sultan Ahmed Mirza, eldest son of Yunus Khan's mentor Abu Sa'id. Qutlugh Nigar Khanum (b. 1459), wife of Umar Shaikh Mirza II, fourth son of Abu Sa'id and younger brother of Sultan Ahmed. Their only son, Babur, would become the founder of the Mughal empire. Khub Nigar Khanim (b. 1463). After her father died, her half-brother (see below) gave her in marriage to Muhammad Hussain Mirza Kurkan. She became the mother of Mirza Muhammad Haidar Dughlat, famous historian and future ruler of Kashmir. Despite his success in making allies, Yunus did not succeed in his project of displacing Esen Buqa, perhaps because he had no experience of war. When Yunus moved to take the town of Kashgar, he was faced by the joined armies of Amir Sayyid Ali of Kashgar and Esen Buqa, and in the ensuing battle, he was defeated. Soon afterwards, he retreated from Moghulistan and returned to the court of Abu Sa'id, who gave him territory around Lake Issyk-Kul as a fiefdom (in appanage). After a while, Yunus Khan again entered Moghulistan and again gained the support of the amirs, but was again unable to make any substantial gains in the country against Esen Buqa. In 1457, dughlat Amir Sayyid Ali of Kashgar (Esen Buqa's ally the previous year) died and his son Saniz Mirza sought Yunus Khan's assistance to gain power in Kashgar. Yunus Khan came into Kashgar after receiving this invitation. Shortly afterwards, he sent one of the most respectable Sayyids of Kashgar, Amir Zia-ud-Din, to Badakhshan to meet Shah Sultan Muhammad Badakhshi and seek one of his six daughters in marriage. Shah Sultan Muhammad Badakhshi (also known as "Prince Lali") was believed to be a direct descendant of Iskandar Zulkarnain (Alexander the Great), son of Filikus Rumi (Philip II of Macedon), who according to (dubious) legend left one of his sons in the isolated mountain country out of reach of rivals in hope that his progeny would continue his dynasty in the East. Prince Lali agreed to give a daughter to Yunus Khan in marriage. He entrusted his fourth daughter, Shah Begum, to Sayyid Zia-ud-Din, who brought her back with him to Kashgar and delivered her over to Yunus Khan, and the wedding was celebrated with due ceremony. Note that Yunus Khan entered into his second marriage just around one year after his first marriage, and he was already around 40 years
