Events
By place
Byzantine Empire
Summer – The Byzantines re-occupy the Cilician cities of Tarsus, Adana and Mamistra. A naval squadron, under Admiral Cantacuzenus, pursues in Cypriot waters a Genoese raiding fleet, and sails on to Latakia, where they capture the harbour and the lower city. Bohemond I reinforces the garrison in the citadel.
Levant
Spring – The Crusaders, led by Bohemond I, re-invade the territory of Aleppo, and try to capture the town of Kafar Latha. The attack fails, owing to the resistance of the local Banu tribe. Meanwhile, Joscelin of Courtenay cuts the communications between Aleppo and the Euphrates.
May 7 – Battle of Harran: The Crusaders under Baldwin II are defeated by the Seljuk Turks. Baldwin and Joscelin of Courtenay are taken prisoner. Tancred (nephew of Bohemond I) becomes regent of Edessa. The defeat at Harran marks a key turning point of Crusader expansion.
May 26 – King Baldwin I captures Acre, the port is besieged from April, and blockaded by the Genoese and Pisan fleet. Baldwin promises a free passage to those who want to move to Ascalon, but the Italian sailors plunder the wealthy Muslim emigrants and kill many of them.
Autumn – Bohemond I departs to Italy for reinforcements. He takes with him gold and silver, and precious stuff to raise an army against Emperor Alexios I (Komnenos). Tancred becomes co-ruler over Antioch – and appoints his brother-in-law, Richard of Salerno, as his deputy.
Toghtekin, Seljuk ruler (atabeg) of Damascus, founds a short-lived principality in Syria (the first example of a series of Seljuk ruled dynasties).
