June 8 – General Isaac Komnenos proclaims himself emperor in Paphlagonia (modern Turkey), and starts a civil war against Emperor Michael VI. He advances with a Byzantine expeditionary force towards Constantinople. At the same time, Michael sends an army against the rebels – western regiments and eastern ones (those from the Anatolic Theme and Charsianon) – to stop him.[1]
August 20 – Battle of Hades: Rebel forces under Isaac Komnenos defeat the Byzantines on the plains of Hades (near Nicaea). General Katakalon Kekaumenos routs the imperial right flank, and reaches the enemy's camp. He destroys the tents and supplies, which leaves the way open to Constantinople.
September 1 – A riot in favor of Isaac Komnenos breaks out in Constantinople. Patriarch Michael I convinces Michael VI to abdicate the throne, and Isaac is crowned as emperor of the Byzantine Empire.
