Spring – Emperor Alexios I Komnenos sends a Byzantine expeditionary force under General Tatikios to Nicaea, in an attempt to re-capture the city from the Seljuk Turks. However, the arrival of Barkiyaruq's army en route stops the Byzantines. Alexios sends reinforcements; short of supplies, the Seljuk Turks retreat. Abu'l-Qasim, Seljuk governor of Nicaea, is defeated and forced to conclude a truce with Alexios.[1]
October – Seljuk sultan Mahmud I dies after a 2-year reign. He is succeeded by his brother Barkiyaruq (one of the Seljuk princes who claim the throne) as ruler of the Seljuk Empire.
