Hegemony is over. Worldviews collide. To grasp world politics, look beyond power and economics—to the battle of ideas. What truly drives the course of history—power, economics, or something even deeper? In Clash of Worldviews , Haneul Jung reveals the ideological struggle that lies beneath every geopolitical shift—struggles that define not just the actions of nations but the rationale behind them. From the rise and fall of empires to the birth of the modern international order, worldviews have served as the cornerstone of human civilization. Today, as the liberal world order frays and competing visions for global governance emerge, understanding these foundational ideas has never been more crucial. This book delivers a comprehensive examination of the ideological forces that have shaped history’s pivotal transformations, from classical liberalism to 21st-century nationalism, from realist power dynamics to utopian globalism, and from postmodern progressivism to post-liberalism. As the post-Cold War era gives way to new visions competing for dominance, Clash of Worldviews offers a practical lens for understanding the ideological currents shaping the 21st century—revealing that every transformation is, at its core, a contest of worldviews.
