===Liu Bei's reign===
{{see also|Battle of Xiaoting}}

Liu Bei ruled as emperor for less than three years. In 222, he launched a campaign against [[Sun Quan]] to retake [[Jingzhou (ancient China)|Jing Province]] and avenge [[Guan Yu]], culminating in the [[Battle of Xiaoting]]. However, due to grave tactical mistakes, Liu Bei suffered a crushing defeat at the hands of Sun Quan's general, [[Lu Xun (Three Kingdoms)|Lu Xun]], and lost the bulk of his army. He survived the battle and retreated to [[Baidicheng]], where he died from illness a year later.
