- Spring – Mawdud ibn Altuntash, Turkic ruler (atabeg) of Mosul, leads an expedition to capture the territories of the Crusaders (belonging to the County of Edessa) east of the Euphrates River.

- 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.

On December 4, the city capitulates (under notably terms) to Baldwin.
