Events

Spring – The Normans under Duke Robert Guiscard take Dyrrhachium (modern-day Durrës) in Illyria and advance inland, capturing most of Macedonia and Thessaly. Robert is forced to leave Greece to deal with an uprising in Italy. He leaves his son Bohemond in charge of the army, who lays siege to the city of Larissa. Emperor Alexios I Komnenos mobilizes a new army, and with the support of 7,000 Seljuk Turks he clears Thessaly from the Normans.^[1]
Byzantine–Venetian treaty: Alexios I signs a trade and defence pact with Venice, in the form of an imperial Golden Bull. He grants the Venetians a commercial colony in Constantinople, as well as free trading and exemption from taxes, throughout the Byzantine Empire in return for their defense of the Adriatic Sea against the Normans.^[2]

May 12 – Battle of Mailberg: Duke Vratislaus II of Bohemia invades Austria with an army of 8,000 men (supported by mercenaries from Moravia and Bavaria). He defeats the forces under Margrave Leopold II ("the Fair") near Mailberg. The northern region of Lower Austria is devastated from pillage and famine.
