1122

By place

Byzantine Empire

• Battle of Beroia: Emperor John II Komnenos transfers the Byzantine field army from Asia Minor (where it has been engaged against the Seljuk Turks) to the Balkans. The Pechenegs who have set up their camp (defended by a circular formation of wagons) near Beroia (modern Bulgaria) are defeated. John orders the Varangian Guard (some 480 men), the elite Palace Guard to hack their way through the Pecheneg circle of wagons, causing a general rout in their camp. Pecheneg survivors are taken captive and enlisted into the Byzantine army.

Belek offers Joscelin liberty in return for the cession of Edessa. He refuses to accept these terms; Joscelin and Waleran and 60 other Crusaders are taken to the castle at Kharput.

Europe

• August 8 – A Venetian fleet under Doge Domenico Michiel with well over a hundred ships sets sail from Venice, carrying an army of around 15,000 men and siege-material on the Venetian Crusade. The fleet departs for Palestine – but the Venetians pause to attack Corfu (this in retaliation for the refusal of John II to renew exclusive trading privileges). For six months, throughout the winter of 1122–23, the Venetians lay siege to the Byzantine island.
• King Alfonso the Battler of Aragon creates the lay community of knights known as the Confraternity of Belchite. It is the first local attempt to imitate the Order of the Knights Templar created in Palestine.
