Events
By place
Byzantine Empire
May 11 – Emperor Leo VI (the Wise) dies after a 26-year reign in which he has completed the Byzantine code of laws (Basilika). He is succeeded by his brother Alexander III as emperor (basileus) alongside Leo's 6-year-old son Constantine VII. 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.
Orso II Participazio becomes the doge of Venice. He sends his son Pietro to Constantinople in order to re-establish the relationship with Alexander III.
King Ordoño II of Galicia continues his expansion of the Christian polity. He sacks the cities of Mérida and Évora.
