The Battle of Krasos was a battle in the Arab–Byzantine Wars that took place in August 804, between the Byzantines under Emperor Nikephoros I and an Abbasid army under Ibrahim ibn Jibril. Nikephoros' accession in 802 resulted in a resumption of warfare between Byzantium and the Abbasid Caliphate. In late summer 804, the Abbasids had invaded Byzantine Asia Minor for one of their customary raids, and Nikephoros set out to meet them. He was surprised, however, at Krasos and heavily defeated, barely escaping with his own life. A truce and prisoner exchange were afterwards arranged. Despite his defeat, and a massive Abbasid invasion the next year, Nikephoros persevered until troubles in the eastern provinces of the Caliphate forced the Abbasids to conclude a peace.
The 806 invasion of Asia Minor was the largest of a long series of military operations launched by the Abbasid Caliphate against the Byzantine Empire. The expedition took place in southeastern and central Asia Minor, where the two states shared a long land border.
