Following Emperor Manuel Komnenos's defeat at the Battle of Myriokephalon (1176) the Byzantines failed to implement all the conditions, particularly the destruction of border fortresses, demanded by the Seljuq sultan Kilij Arslan II as a prerequisite for a cessation of hostilities.[3] A substantial Seljuq cavalry army, including Turcoman nomad auxiliaries, was dispatched into Byzantine territory, in the Meander Valley in western Anatolia, on a retaliatory raid.
