The dominance of the Western International order and institutionalization of Western civilization within it caused the ancient Eastern civilizations to have common and similar experiences of marginalization and to be portrayed as "inferiors" and "uncivilized" nations. The reproduction of similar strategic culture's elements of these civilizations has led to a common demand to regain their former role and status in the International System. In this context, the main question is what factors have led to the re-orientation of the revisionist Eastern civilizations towards each other and the international system, which revived the civilizational discourse? The overall result of the research shows that the long-standing civilizational war, as well as a similar strategic culture between Iranian, Chinese and Russian civilizations, led to the formation of an Eastern historical-civilizational bloc that seeks to create two Eastern and Western "bounded orders" against Western international order. The method adopted in this research is descriptive-analytical and its theoretical framework is based on Samuel Huntington's Clash of Civilizations theory and Robert Cox's Critical Theory.
