Liu Chang (刘长, Lưu Trường; 198–174 BC; Prince Li of Huainan 淮南厉王), was the turbulent, ferocious seventh son of founding Emperor Gaozu Liu Bang, raised in the imperial palace by Empress Lü (Empress Lü).
Possessing titanic physical strength capable of lifting bronze cauldrons with his bare hands, Liu Chang was favored and indulged by his elder brother Emperor Wen (Liu Heng). Harboring bitter fury over his birth mother Consort Zhao’s suicide, Liu Chang assassinated senior minister Shen Yiji (审食其) in broad daylight with a concealed bronze hammer. Increasingly arrogant, he enacted his own laws in Huainan and plotted a massive rebellion with the Minyue tribes against Emperor Wen in 174 BC. Uncovered before the revolt began, Emperor Wen spared his life out of fraternal love, exiling him in a barred carriage to Sichuan. In fierce, unyielding pride, Liu Chang refused all food and starved himself to death on the road at age twenty-four.
Role in History (Shiji)
Records of the Grand Historian (Shiji, vol. 118, House of Huainan): “Liu Chang killed Shen Yiji with an iron hammer in the streets, yet Emperor Wen forgave him. When his rebellion failed, he kicked the barred cage, roaring: ‘A prince does not eat prisoner’s gruel!’ He starved to death, and the people sang a folk lament: ‘One shoe of cloth can be sewn; two brothers cannot share one world.'”
