Byzantine Empire

• May - September - Rus'–Byzantine War: The Rus' and their allies, the Pechenegs, under the Varangian prince Igor I of Kiev, cross the Black Sea with an invasion fleet of 1,000 ships and disembark on the northern coast of Asia Minor. While the Byzantine fleet is engaged against the Arabs in the Mediterranean, the Rus' forces reach the gates of Constantinople. Emperor Romanos I organizes the defense of the capital and assembles 15 old ships under the chamberlain Theophanes. The Byzantines repel the Rus' fleet but can not prevent the invaders from pillaging the hinterland of Constantinople, venturing as far south as Nicomedia. In September, John Kourkouas and Bardas Phokas, two leading generals, destroy the Rus' forces in Thrace. Igor manages, with only a handful of boats, to escape to the Caspian Sea.
