Samarkand, and Hamza Sultan to Gissar. Shaybani Khan himself with a small detachment went to Merv (Mary, present-day Turkmenistan). Death Shah Ismail I was alarmed by Shaybani's success and moved against the Uzbeks. In 1510, Shaybani Khan was in Herat. At this time, Ismail I, having learned about the failures of Shaybani Khan in the battle against the Hazaras, invaded Western Khorasan and began to rapidly advance towards Herat. Shaybani Khan did not have a strong army at his disposal. During the military campaign against the Hazaras, he lost most of his cavalry. The main army was stationed in Mawarannahr, so he, having consulted with his emirs, hastened to hide behind the walls of Merv. Safavid troops captured Astrabad, Mashhad, and Sarakhs. All Shaybani's emirs who were in Khorasan, including Jan Wafa, fled from the Safavid-Qizilbash army and arrived to Merv.

After these words of Mogul Khanum, everyone seemed to be ashamed, and the Khan's troops went into battle, which resulted in their complete defeat and the death of Shaybani Khan. In the Battle of Marv (1510), Muhammad Shaybani was defeated and killed when trying to escape. Shaybani Khan's army was surrounded by Ismail's 17,000-strong army and was defeated after fierce resistance. The remnants of the army ended up dying under enemy arrows. At the time of Shaybani's death, the Uzbeks controlled all of
