Haidar was killed, breaking Uzbek power until the rise of Muhammad Shaibani by the end of the century. Yunus' dealings with the Timurids were far more complex. The Timurid ruler Abu Sa'id had been Yunus Khan's great mentor in life, who had called him from obscurity and exile in Iran and bestowed lands and an army upon him. After Abu Sa'id Mirza was killed by the White Sheep Turkmen in 1468, his realm was split between his sons. The eldest son, Sultan Ahmad Mirza, ruled over Samarkand & Bukhara, the third son, Sultan Mahmud Mirza took Balkh & Badakhshan, and the fourth son, Umar Shaikh Mirza II, became the ruler of Ferghana. All three of these princes were to eventually marry three daughters of Yunus Khan, but his relationship with them began on a discordant note. By the time Abu Sa'id Mirza was killed in 1468, Yunus Khan had been overlord of the Mughals for about six years. During this time, his support among his principal amirs (noblemen) had eroded. The amirs were apparently upset over Yunus Khan's desire to reside in towns and abandon the traditional nomadic way of life. Since Yunus Khan had spent much of his early life in the towns of Yazd and Shiraz as a student, he had developed a taste for settled life in towns and a certain discomfort with the nomadic lifestyle of his community, the Mughals. This was a major issue in that milieu, and the amirs invited Sultan Ahmad's governor of Tashkent, Shaikh Jamal Khan, to displace Yunus Khan and usurp power. This duly happened; the Moghuls submitted to Shaikh Jamal Khan, who took over power and also imprisoned Yunus Khan for a year. However, the amirs soon had cause to regret the choice they had made, for Shaikh Jamal Khan was not a wise and moderate man; he was given to over-reach and excess. He demonstrated these qualities strikingly when he gave Yunus Khan's first wife, Isan Daulat Begum, maternal grandmother of Babur, as a present (or booty of war) to his officer Khoja Kalan. When Khoja Kalan entered Isan Daulat Begum's apartments to claim her for himself, he was trapped inside and killed there by female attendants of Isan Daulat Begum, and thus the lady managed to preserve her honour. Khoja Kalan lost his life, and Shaikh Jamal Khan who lost his honour in the eyes of the amirs
