In 1108, Tancred refused to honour the Treaty of Devol, in which Bohemond swore an oath of fealty to Alexius, and for decades afterwards Antioch remained independent of the Byzantine Empire. In 1110, he brought Krak des Chevaliers under his control, which would later become an important castle in the County of Tripoli. Tancred remained regent in Antioch in the name of Bohemond II until his death in 1112 during a typhoid epidemic. He had married Cecile of France, but died childless.
