Since the nineteenth century, many historians have focused on the absolute cause of historical phenomenon within a single scale of time and space according to the specialization of academic fields. Historical studies of some nations in Western Europe and Asia have offered a base to develop modern nations by emphasizing national identity or the importance of a unified nation to define people as the single community. In this process, discourses in which the superiority of Western Europe was overemphasized or hegemony appeared, and these are recognized today as Eurocentric. As a result, some nations of Western Europe have justified their historical experiences as the universal history of all human beings. 1 In this historical discourse, many other regions except Western Europe were excluded, and Europe was identified as the center of world history.
