Biography & Historical Record

Sun Ba (孙霸, Tôn Bá) (died 250 AD), courtesy name Ziwei (子威, Tử Uy), fourth son of Sun Quan (孙权, Tôn Quyền) and Lady Wang, was created Prince of Lu in 242. Sun Quan’s equal treatment of Ba and crown prince Sun He (孙和, Tôn Hòa) ignited the Two Palaces Contention. Ba’s clique included Grand Commander Quan Cong (全琮, Toàn Tông), Grand Chancellor Bu Zhi (步骘, Bộ Chất), strategist Yang Zhu (杨笁, Dương Trúc), and powerful half-sister Sun Luban (孙鲁班, Tôn Lỗ Ban). Their attacks on the heir’s party persecuted Lu Xun (陆逊, Lục Tốn) and other loyalists until the aging emperor, seeing the realm wrecked, executed chief conspirators and ordered Sun Ba to commit suicide in 250.

Historically Ba is the ambitious younger prince whose faction nearly tore Wu apart; the novel compresses the same moral—imperial favoritism breeding civil war inside one house. His death closed one half of the dual-palace wound but did not restore Sun He; Sun Quan instead elevated child Sun Liang (孙亮, Tôn Lượng).

Role in Romance of the Three Kingdoms

Romance of the Three Kingdoms stages Sun Ba as the rival prince whose palace challenges Sun He’s legitimacy. Court ministers divide; slander and privilege escalate; Sun Quan’s late crackdown kills Ba’s partisans and Ba himself. The episode is the novel’s chief illustration of Wu’s self-destructive succession politics after Sun Deng (孙登, Tôn Đăng) dies.
