Though initially defiant, the ruler of the kingdom, Yusuf Sufi, eventually submitted and offered his niece Khanzada Begum in marriage to Jahangir. Khanzada was the daughter of Yusuf's brother Aq Sufi by Shakar Beg, a daughter of Jani Beg, Khan of the Golden Horde. The following year, Khanzada was sent to Timur's capital of Samarqand with a large procession carrying gifts, including gems, precious metals, silks and tapestries. She was escorted by a retinue of handmaidens and mounted soldiers, while she herself rode veiled on a white camel. Jahangir had a son and a daughter by this marriage, Muhammad Sultan Mirza and Yadigar Sultan. Jahangir died of illness only two years after his marriage in 1376. Timur was reportedly inconsolable by his son's death, which caused a hiatus in his otherwise continuous military campaigns. Yazdi states that "Everything then became melancholy and disagreeable to him and his cheeks were almost always bathed in tears; he clothed himself with mourning, and his life became uneasy to him. The whole kingdom, which used to be overjoyed at the arrival of this great emperor, was turned into a place of sorrow and weeping." He was buried in a tall edifice termed the "Tomb of Jahangir", part of the Dorussaodat mausoleum complex in modern-day Shahrisabz. Presently, the tomb is the best surviving part of the structure. Jahangir had six children by three wives:  By Khanzada Begum, daughter of Aq Sufi Qongirat By Ruqayya Khanike, daughter of Amir Kai-Khusrau Apardi By Bakht Malik Agha, daughter of Ilyas Khwaja Tatar Yasauri
