Treaty of Devol

September 1, 1108

Bohemond of Antioch, defeated and humiliated, swore vassalage to Emperor Alexios I for Antioch and promised to return territories to the empire. The treaty was never fully implemented; Bohemond died before he could do so and his nephew Tancred simply ignored it. The document nonetheless established a Byzantine legal claim to Antioch that Constantinople would invoke for decades whenever relations with the Franks soured.
