Tashkent was conquered by Yunus Khan, the Khan of Moghulistan during the Timurid Civil Wars. After he died in 1487 CE, his son Sultan Mahmud Khan became the new Khan. With this change of power in Tashkent, the Timurids of Ferghana ordered by Umar Shaikh Mirza II decided to attack Tashkent and placed a strong army in the Ushtar Fort.[1] However, Sultan Mahmud Khan marched quickly to besiege the fort and took it by assault.
