Events
By place
Europe
Sicilian Berbers in Agrigento revolt and depose the independent Emir Ahmed ibn Khorob. They offer Sicily to the Fatimid Caliphate in Ifriqiya (modern Tunisia). Caliph Abdullah al-Mahdi Billah welcomes this turn of events, but refuses to grant the Berber rulers their autonomy. He sends a Fatimid expeditionary force under Abu Said Musa which lands in Sicily and, with some difficulty, takes control of the island. Abdullah al-Mahdi Billah appoints Salam ibn Rashid as the emir of Sicily. Ahmed ibn Khorob is dispatched to Raqqada and executed.
Britain
Lady Æthelflæd, daughter of the late King Alfred the Great and the widow of Earl Æthelred of Mercia, sends an army into Brycheiniog to avenge the murder of the Mercian abbot Ecbryht and his companions. They seize and burn the royal fort of King Tewdr of Brycheiniog at Llangorse Lake (Wales), and take the queen and thirty-three others captive.
