The Clash of Civilizations and the Remaking of World Order is a renowned book by Samuel P. Huntington that explores the role of civilizations in shaping global politics. Huntington argues that in the post-Cold War era, conflicts will primarily occur between different civilizations rather than nation-states. He examines the cultural, religious, and historical factors that contribute to these clashes and provides insights into the challenges faced by international relations in a world divided along civilizational lines.
