Li Jing

Li Jing (571 – July 2, 649), courtesy name Yaoshi, posthumously known as Duke Jingwu of Wei (also spelled as Duke of Wey), was a Chinese military general, strategist, and writer who lived in the early Tang dynasty and was most active during the reign of Emperor Taizong. In 630, Li Jing defeated the Göktürks, led by Jieli Khan, with just 3,000 cavalry soldiers in a surprise attack, allowing the Tang Empire to subjugate the Göktürks and reduce them to the status of a vassal under the Tang Empire. Li Jing and Li Shiji are considered the two most prominent early Tang generals.
