Bohemond I of Antioch

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.
