Alexander becomes de facto ruler of the Byzantine Empire and expels Empress Zoe Karbonopsina, the mother of Constantine, from the palace and exiles her to a nunnery.

#### Europe

* German dukes Henry the Fowler of Saxony and Arnulf I (the Bad) of Bavaria claim themselves to be sovereign princes, not recognizing the authority of their overlord, King Conrad I of the East Frankish Kingdom, as he is not a Carolingian. Duke Erchanger II of Swabia and Conrad's brother, Duke Eberhard III of Franconia, support the Conradines.
