The Battle of Bagrevand puts an end to an Armenian rebellion against the Abbasid Caliphate. Muslim control over Transcaucasia is solidified and its Islamization begins, while several major Armenian nakharar families lose power and their remnants flee to the Byzantine Empire.
The Battle of Bagrevand was fought on 25 April 775, in the plains of Bagrevand, between the forces of the Armenian princes who had rebelled against the Abbasid Caliphate and the caliphal army. The battle resulted in a crushing Abbasid victory, with the death of the main Armenian leaders. The Mamikonian family's power in particular was almost extinguished. The battle signalled the beginning of large-scale Armenian migration into the Byzantine Empire.
