This research examines the Chunqiu Era, also known as the Spring and Autumn Period, which occurred in ancient China from 770 to 476 BCE. The objective is to analyse this historical period within the framework of contemporary international relations (IR) theory. The primary objective of this research is two-fold: firstly, to examine the application of International Relations (IR) theories, specifically Power Transition Theory and Hegemonic Dynamics, within the context of ancient history; and secondly, to promote an interdisciplinary methodology that integrates archaeological, geographical, and philosophical perspectives in the analysis of this particular time period. The present study utilises an interdisciplinary approach, incorporating historical analysis, archaeological evidence, geographical data, and philosophical perspectives. This study examines the historical records and archaeological discoveries of the Chunqiu Era, employing Geographic Information System (GIS) technology to analyse various geographical aspects. Through the analysis of concurrent occurrences in adjacent civilizations and the integration of perspectives from other academic fields, this study aims to develop a holistic comprehension of the international relations during the Chunqiu Era. The study reveals the continuing significance of modern International Relations theories when applied to the Chunqiu Era, exposing recurring patterns of power shifts, challenges to hegemony, and diplomatic strategies. This statement underscores the significance of taking into account cultural, geographical, and temporal intricacies while modifying international relations theories to suit ancient circumstances. Furthermore, the research highlights the importance of incorporating multidisciplinary and cross-cultural studies to enhance the understanding of historical events. The research findings have far-reaching ramifications for both the academic community and society as a whole. This highlights the versatility of IR theories in accommodating various historical contexts, hence promoting their wider utilisation. Interdisciplinary techniques can offer valuable contributions to future research endeavours by augmenting historical study and fostering a deeper comprehension of interconnection. The present study contributes to the advancement of knowledge in the field of ancient Chinese history and underscores the need of incorporating multiple cultural viewpoints in the pursuit of historical research.
