Nikephoros I's accession to the Byzantine throne in 802 ended a prior period of peace and renewed hostilities between Byzantium and the Abbasid Caliphate. In late summer 804, an Abbasid army under Ibrahim ibn Jibril launched one of its customary raiding campaigns into Byzantine Asia Minor, prompting Nikephoros to personally lead a force to intercept it.
The Byzantine army under Nikephoros I was caught off guard at Krasos in August 804. The Abbasids inflicted a heavy defeat on the Byzantines, with the emperor barely escaping with his life. The battle demonstrated the effectiveness of Abbasid raiding strategy against Byzantine defensive responses in Asia Minor.
Following the defeat, a truce and prisoner exchange were negotiated between the two powers. Despite this setback and a major Abbasid invasion the following year, Nikephoros continued resistance. Internal troubles in the eastern provinces of the Caliphate eventually compelled the Abbasids to conclude a peace with Byzantium.
