Liang Shidu (梁師都) (died June 3, 628) was an agrarian leader who rebelled against the rule of the Chinese dynasty Sui Dynasty near the end of the reign of Emperor Yang of Sui. He, claiming the title of Emperor of Liang with the aid from Eastern Tujue, retained the modern northern Shaanxi and western Inner Mongolia region for over a decade, but was gradually weakened by attacks from Tang Dynasty, whose founding emperor Emperor Gaozu and successor Emperor Taizong had eliminated the rival contenders for power one by one, leaving Liang isolated. In 628, with Eastern Tujue in internal turmoil and unable to come to his aid, Emperor Taizong launched another attack on Liang. Liang's cousin Liang Luoren (梁洛仁) assassinated him and surrendered, completing Tang's drive to reunite China after Sui's collapse.
