The siege of Nicaea was the first major battle of the First Crusade, taking place from 14 May to 19 June 1097. The city was under the control of the Seljuk Turks who opted to surrender to the Byzantines in fear of the Crusaders breaking into the city. The siege was followed by the Battle of Dorylaeum and the Siege of Antioch, all taking place in modern Turkey.
