Summer –Constantine Doukas, a Byzantine general (magister militum), tries, unsuccessfully, with the support of several aristocrats to usurp the throne from the young Constantine VII. He is killed in a clash by the soldiers of the Hetaireia guard, assembled by John Eladas. His head is cut off and presented to Constantine.
Caliph Abdullah al-Mahdi Billah of the Fatimid Caliphate replaces the unpopular governor Ibn Abi Khinzir with Ali ibn Umar al-Balawi. But the Sicilian lords find this unacceptable and decide to declare independence of Sicily. They acknowledge allegiance to the Abbasid caliph Al-Muqtadir and acclaim an Aghlabid prince, Ahmed ibn Khorob, as emir of Sicily. The Sicilians re-launch their conquest of Byzantine Calabria, while Ahmed ibn Khorob in Sicily leads a successful assault against the North African cities of Sfax and Tripoli.
