Liu Zhang
Liu Zhang put down an insurrection caused by Hu Mao, an agent of the Chang'an regime. In 200 Zhang Lu openly defied Liu Zhang, who in retaliation killed Zhang Lu's mother, who had been staying at his court as hostage. Zhang Lu invaded Liu Zhang's territory, occupying northern Ba Commandery. A follower of Liu Zhang also rebelled at this time due to grievances with the Dongzhou Troops, but he was defeated and killed. After Cao Cao's defeat at the Battle of Red Cliffs in 208, Liu Zhang formed an alliance with Liu Bei. When Cao Cao's general Zhong Yao was sent against Zhang Lu in 211, Liu Zhang invited Liu Bei to Guanghan hoping that someone from the same imperial clan would help him. Liu Bei spent the next year complaining about the lack of supplies, then turned on Liu Zhang, killed his officers, and waged war on him. By 214 Liu Bei's forces had advanced to Chengdu, where a siege lasting several weeks occurred before Liu Zhang surrendered. Liu Zhang was exiled to Jing Province where he eventually entered the court of Sun Quan when his general Lü Meng defeated Guan Yu in 219.
