Muhammad Shaybani
Muhammad Shaybani Khan (Uzbek: Muhammad Shayboniy, Persian: شیبک خان ) also known as Abul-Fath Shaybani Khan or Shayabak Khan or Shahi Beg Khan (c. 1451 – 2 December 1510), was an Uzbek leader who consolidated various Uzbek tribes and laid the foundations for their ascendance in Transoxiana and the establishment of the Khanate of Bukhara. He was a descendant of Shiban (or Shayban), the fifth son of Jochi, Genghis Khan's eldest son.
Shaybani was initially an Uzbek warrior leading a contingent of 3000 men in the army of the Timurid ruler of Samarkand, Sultan Ahmed Mirza under the Amir, Abdul Ali Tarkhan. However, when Ahmed Mirza went to war against Sultan Mahmud Khan, the Khan of Moghulistan, to reclaim Tashkent from him, Shaybani secretly met the Moghul Khan and agreed to betray and plunder Ahmed's army. This happened in the Battle of the Chirciq River in 1488 C.E., resulting in a decisive victory for Moghulistan. Sultan Mahmud Khan gave Turkistan to Shaybani as a reward. Here, however, Shaybani oppressed the local Kazakhs, resulting in a war between Moghulistan and the Kazakh Khanate. Moghulistan was defeated in this war, but Shaybani gained power among the Uzbeks. He decided to conquer Samarkand and Bukhara from Ahmed Mirza. Sultan Mahmud's subordinate emirs convinced him to aid Shaybani in doing so, and together they marched on Samarkand.
