Peter I, emperor (tsar) of the Bulgarian Empire, suffers a stroke and abdicates the throne in favour of his eldest son Boris II. He arrives (after being an honorary hostage at Constantinople) in Preslav and is proclaimed as the new ruler. Boris regains lost territory from the Kievan Rus' and recaptures Pereyaslavets, an important trade city at the mouth of the Danube.[2]
Summer – Grand Prince Sviatoslav I invades Bulgaria at the head of a Kievan army, which includes Pecheneg and Hungarian auxiliary forces. He defeats the Bulgarians in a major battle and retakes Pereyaslavets. Boris II capitulates and impales 300 Bulgarian boyars for disloyalty. Sviatoslav assigns garrisons to the conquered fortresses in Northern Bulgaria.[3]
Pandulf Ironhead, duke of Benevento and Capua, leads the siege of Bovino. He is captured by the Byzantines and taken in chains to Bari, and jailed in Constantinople. Neapolitan forces under Marinus II, duke of Naples, invade Benevento-Capua, capture the city of Avellino and then lay siege to Capua.[4]
Otto I 'the Great', Holy Roman Emperor, assembles a large expeditionary force at Pavia, joined by Spoletan troops. He counter-attacks, relieves the siege of Capua and devastates the area around Naples. Otto enters Benevento, where he is received as 'liberator' by Landulf IV and in the cities of Apulia (Southern Italy).
