The purpose of this paper is to apply Ibn-Khaldun’s dialectic of Asabiyya to explain the nature of relationship between war and the world order in the modern era via ‘macro structural change’. It is argued here that these changes in the world order in the modern times have a dialectical relationship with war. Here, Ibn-Khaldun’s approach to historical change is applied for the explication of this relationship. Ibn-Khaldun’s well-known historiogarphic enterprise does provide us with an analytical framework of how wars have been interrelated with the distribution of power and change in that distribution. This paper attempts to show the historical significance of war for the formation and the disintegration of world order since the 16th century.
