Byzantine emperor Manuel I Comnenus fortified Dorylaeum in 1175, but according to some authorities the Turks recaptured it in 1176 after the Battle of Myriokephalon.[1] However, the contemporary Byzantine historian Niketas Choniates relates that Manuel did not destroy the fortifications of Dorylaeum, as he had agreed to do as part of the treaty he negotiated with the Seljuk Turkish sultan Kilij Arslan II immediately after Myriokephalon.
