The Battle of Sebastopolis was fought at Sebastopolis (mostly identified with Sebaste in Cilicia, but also with modern Sulusaray) in 692 between the Byzantine Empire and Umayyads under the caliphate of Abd al-Malik ibn Marwan. The Battle ended the peace that had existed between the two powers since 680. The Umayyad army was led by Muhammad ibn Marwan. The Byzantines were led by Leontios and included a "special army" of 30,000 Slavs under their leader Neboulos.
