Events

By place

Byzantine Empire

• April 1 – Emperor Nikephoros III is forced to abdicate the throne, and retires to the Peribleptos monastery. He is succeeded by Alexios I Komnenos, who is crowned on April 5, as ruler of the Byzantine Empire. His brother-in-law Nikephoros Melissenos supports Alexios as new emperor, in exchange for the title of Caesar (co-emperor), and is appointed as commander of the Byzantine armies in the West.
• May – A Norman fleet of 150 ships (including 60 horse transports), led by Duke Robert Guiscard, sets off towards the Dalmatian coast. An army of 15,000 men (including about 1,300 Norman knights) sails to the city of Avalona (modern Albania); they are joined by several ships from Ragusa, a republic in the Balkans who are enemies of the Byzantines.
• October 18 – Battle of Dyrrhachium: After taking the island of Corfu, Robert Guiscard advances to Dyrrhachium (modern-day Durrës), and lays siege to the city. Alexios I Komnenos attempts to defend Illyria from the Normans (the first recorded mention of Albania), but is defeated by Guiscard, outside Dyrrhachium, the Byzantine capital city of Illyria.
