Liu Bei (, ; liu2-bei4; 161 – 10 June 223), courtesy name Xuande (玄德), was a Chinese warlord in the late Eastern Han dynasty who later became the founding emperor of Shu Han, one of the Three Kingdoms of China. Although he was a distant relative of the Han imperial family, Liu Bei's father died when he was a child and left his family impoverished. To help his mother, he sold shoes and straw mats. When he reached the age of fifteen, his mother sent him to study under Lu Zhi. In his youth, Liu Bei was known as ambitious and charismatic. He gathered a militia army to fight the Yellow Turbans. Liu Bei fought bravely in many battles and grew famous for his exploits. Later, he participated in the coalition against Dong Zhuo, following this joined his childhood friend Gongsun Zan and fought under him against Yuan Shao.
Later he was sent to help Tao Qian against Cao Cao. Thanks to the support of the influential Mi and Chen families along with Tao Qian's last will, Liu Bei inherited the Xu Province. After his defeat against Cao Cao, Lü Bu joined him. However, Lü Bu took advantage of Liu Bei being away fighting Yuan Shu and seized Xu Province. Later Liu Bei joined Cao Cao and they defeated Lü Bu at the Battle of Xiapi. Although he was treated well by Cao Cao, Liu Bei received a secret edict from the emperor to kill Cao Cao. So, he rebelled against Cao Cao taking back Xu province. After a brief alliance with Yuan Shao, Liu Bei was quickly defeated by Cao Cao and had to join Yuan Shao. He was sent by Yuan Shao to create uprisings behind Cao Cao's main base, and later joined his kinsman Liu Biao. Although, Liu Biao treated him well, he doubted Liu Bei's loyalty, so he sent him to Xinye to serve as a shield against Cao Cao. According to the Wei Shu (魏書) and Records of Heroes. Like Tao Qian, Liu Biao desired to have Liu Bei inherit his province over his sons however Liu Bei refused. After Liu Biao's death, Liu Bei and his supporters joined Liu Qi in Xiakou where they allied with Sun Quan. Together they opposed Cao Cao at the Battle of Red Cliffs.
