Abstract
The Crusades are a period of struggle between the East and the West, or between Muslims and Christians, covering nearly two centuries. However, much of the academic research on the Crusades is European-centered and written by experts of the Middle Ages of the West. Changing this viewpoint whose impressions about the Muslim perspective are incomplete and distorted is possible by reconsidering the History of the Crusades from an East / Muslim point of view. In this study, the first reaction of the Muslims against Crusades, the situation of the Seljuk State, the struggles between Frenk and Turks after the seizure of Seljuqan capital İznik by the Crusaders and the collapse of Urfa and Antakya cities will be discussed in the axis of the first Crusade. The sources of the research constitute the chronicles, biographies and geographical studies related to the subject.
