The second Battle of Dorylaeum took place near Dorylaeum in October 1147, during the Second Crusade. It was not a single clash but consisted of a series of encounters over a number of days. The German crusader forces of Conrad III were defeated by the Seljuk Turks led by Sultan Mesud I.


Following escalating friction between the Byzantine Empire and the German crusader army, including armed clashes, the Germans were ferried from the environs of Constantinople to the Asiatic shores of the Bosphorus. With inadequate supplies, the crusaders moved into the interior of Anatolia, intending to take the overland route to the Holy Land.[1]
