The Battle of the Chirciq River was fought between Sultan Mahmud Khan of Moghulistan and Sultan Ahmed Mirza, the Timurid ruler of Samarkand & Bukhara in 1488 CE over the city of Tashkent. The Moghuls decisively defeated the Timurids as a result of the defection of 3,000 Uzbeks under the command of Muhammad Shaybani Khan.[1]
