Treaty of Devol
The Treaty of Devol was signed in 1108 between Bohemond I of Antioch and the Byzantine Emperor Alexios I Komnenos. It was intended to make the Principality of Antioch a vassal state of the Byzantine Empire. Antioch came temporarily under Byzantine sway in 1137, but it was not until 1158 that it truly became a ByzantineVassal.
