This article critically examines Samuel Huntington's controversial theory of the "Clash of Civilizations" and its contemporary relevance in understanding global conflicts and tensions. Huntington's premise, introduced in 1993, proposed that the post-Cold War era would be characterized by conflicts arising from cultural and religious differences between civilizations, rather than ideological divisions. Through a comprehensive analysis of Huntington's seminal work, this paper explores the core arguments, assumptions, and implications of his theory. It investigates Huntington's assertion that the West's dominance is waning, and the rise of non-Western civilizations, particularly the Islamic world, will lead to inevitable clashes and competition for power and resources. The article delves into the ongoing debates surrounding Huntington's ideas, examining both the support and criticism it has garnered from scholars and political analysts. It critically assesses the theory's explanatory power in the context of contemporary global events, such as the rise of religious extremism, the Israeli-Palestinian conflict, and the tensions between the West and the Islamic world. By synthesizing diverse perspectives and drawing upon historical evidence and empirical data, the paper aims to provide a nuanced understanding of the strengths and limitations of Huntington's theory. It evaluates the extent to which the "Clash of Civilizations" framework remains relevant in the 21st century and offers insights into alternative approaches to addressing cultural conflicts and promoting dialogue and understanding between civilizations. Overall, this article contributes to the ongoing scholarly discourse on Huntington's influential work, offering a critical analysis of its contemporary applicability and implications for global security, international relations, and intercultural harmony
