February–May – The Crusaders under Baldwin I besiege Beirut. The Genoese and Pisan ships blockade the harbour, Fatimid ships from Tyre and Sidon try in vain to break the blockade. The Fatimid governor flees by night through the Italian fleet to Cyprus. On May 13, Baldwin captures the city by assault. The Italians conduct an massacre among the inhabitants.
October–December – The Crusaders under Balwin I (supported by King Sigurd I) besiege Sidon. Norwegian ships blockade the harbour – but are nearly dispersed by a powerful Fatimid flotilla from Tyre. They are saved by the arrival of a Venetian squadron under Doge Ordelafo Faliero. On December 4, the city capitulates (under notably terms) to Baldwin.
King Henry V invades Italy with a large army and concludes an agreement with Pope Paschal II at Sutri. Henry renounces the right of investiture (a dispute with the former Henry IV) in return that Paschal promises to crown him emperor and to restore to the Holy Roman Empire all the lands given to the German church (since the time of Charlemagne).
