Bohemond I of Antioch vs Li Chengliang

Bohemond led the capture of Antioch during the First Crusade. He negotiated with a traitor inside the city to open a gate, allowing the crusaders to enter. He then claimed the city for himself, becoming Prince of Antioch.

Bohemond and Baldwin of Edessa were defeated by a combined Seljuk force at the Battle of Harran. Bohemond was captured and held for ransom, weakening the Principality of Antioch.

After his release, Bohemond launched a campaign against the Byzantine Empire, besieging Dyrrhachium. He was forced to surrender in 1108 and sign the Treaty of Devol, which made Antioch a vassal of Byzantium.

Bohemond signed the Treaty of Devol with Byzantine Emperor Alexios I Komnenos. The treaty recognized Bohemond as Prince of Antioch but made him a vassal of the Byzantine Empire, a humiliation that ended his ambitions.

Li Chengliang was appointed as the commander of the Liaodong military region, responsible for defending the Ming frontier against the Jurchen tribes. He held this post for decades, becoming the dominant military figure in the northeast.

Li Chengliang led a series of punitive expeditions against the Jianzhou Jurchens under Wang Gao, destroying their strongholds and killing thousands. These campaigns temporarily subdued the Jurchen threat but also fostered resentment.

Li Chengliang supported the young Jurchen leader Nurhaci, providing him with military backing and resources. This patronage inadvertently helped Nurhaci unify the Jurchen tribes, creating the future threat of the Later Jin dynasty.

Li Chengliang was accused of corruption, including embezzling military funds and accepting bribes from Jurchen leaders. His wealth and power grew unchecked, and he was criticized for prioritizing personal gain over frontier defense.

Li Chengliang retired from military service in his late 80s and died shortly after. His long tenure in Liaodong left a mixed legacy: he stabilized the frontier but also enabled the rise of Nurhaci, who would later overthrow the Ming.
