The Battle of Dorylaion or Dorylaeum took place during the First Crusade on 1 July 1097 between the crusader forces and the Seljuk Turks, near the city of Dorylaion in Anatolia. Though the Turkish forces of Kilij Arslan nearly wiped out the Crusader contingent of Bohemond of Taranto, other Crusaders arrived just in time to reverse the course of the battle.
