The Western-based understanding of history is periodized as the Ancient Age (slavery), the Middle Ages (feudalism), the New Age (capitalism) and the Modern Age (industrialism). However, these periods are periodic distinctions that the West produces from within itself and are the result of its own conditions, in other words, the West-centered universal historical and social understanding. By centering its own understanding of history and adding other societies to this understanding of history with a hegemonic approach, the West actually hides its own colonialism and aggression and positions itself at the center of civilization. According to Sezer, world history consists of the history of East-West conflict. The reason for the conflict is that the West, in an aggressive manner, wants to take the wealth of the East by force, just like in the American continent. In Baykan Sezer's theory, it is stated that the East first became civilized with its own efforts and solutions, and later the West also became civilized as a result of its conflict-based relations with the East. In this context, the study re-evaluates the periods of the Ancient Age, the Middle Ages, the New Age and the Modern Age, which express slavery, feudalism, capitalism and industrialism on the basis of agricultural activities. Thus, the self-made despotic historical society imposed by the West will be criticized, and it will be tried to demonstrate that, contrary to the idea that the West developed within itself, it developed on the basis of its conflictual relations with the East. Baykan Sezer’s articles and books with his notes were examined with a qualitative approach and document analysis method. The importance of the study is that it offers a different perspective to better analyze the past and evaluate the future more accurately.
