E.H. Carr's Twenty Years' Crisis is a classic work in International Relations. Published in 1939, on the eve of World War II, it was immediately recognized by friend and foe alike as a defining work in the fledgling discipline. The author was one of the most influential and controversial intellectuals of the twentieth century. The issues and themes he develops in this book continue to have relevance to modern day concerns with power and its distribution in the international system. Michael Cox's critical introduction provides the reader with background information about the author, the context for the book, its main themes and contemporary relevance. Written with the student in mind, it offers a guide to understanding a complex, but crucial text.

The liberal order is decaying. Will it survive, and if not, what will replace it? On the eightieth anniversary of the publication of E.H. Carr's The Twenty Years' Crisis, 1919-1939, Philip Cunliffe revisits this classic text, juxtaposing its claims with contemporary debates on the rise and fall of the liberal international order. The New Twenty Years' Crisis reveals that the liberal international order experienced a twenty-year cycle of decline from 1999 to 2019. In contrast to claims that the order has been undermined by authoritarian challengers, Cunliffe argues that the primary drivers of the crisis are internal. He shows that the heavily ideological international relations theory that has developed since the end of the Cold War is clouded by utopianism, replacing analysis with aspiration and expressing the interests of power rather than explaining its functioning. As a result, a growing tendency to discount political alternatives has made us less able to adapt to political change. In search of a solution, this book argues that breaking through the current impasse will require not only dissolving the new forms of utopianism, but also pushing past the fear that the twenty-first century will repeat the mistakes of the twentieth. Only then can we finally escape the twenty years' crisis. By reflecting on Carr's foundational work, The New Twenty Years' Crisis offers an opportunity to take stock of the current state of international order and international relations theory.

In this book, first published in 1940, Leonard Woolf lays out the necessity for the establishment of a system providing for the rule of international law and cooperation, control of international power and collective defence against international aggression. He lays bare the issues at stake in the Second World War and draws lines on which a lasting peace could be framed.

This cutting-edge textbook provides a comprehensive introduction to international relations theory. Arguing that theory is central to explaining the dynamics of world politics, it includes a wide variety of theoretical positions--from the historically dominant traditions to powerful critical voices since the 1980s. The editors have brought together a team of international contributors, each specializing in a different theory. The contributors explain the theoretical background to their positions before showing how and why their theories matter. The book opens up space for analysis and debate, allowing students to decide which theories they find most useful in explaining and understanding international relations.

Overextension is the common pitfall of empires. Why does it occur? What are the forces that cause the great powers of the industrial era to pursue aggressive foreign policies? Jack Snyder identifies recurrent myths of empire, describes the varieties of overextension to which they lead, and criticizes the traditional explanations offered by historians and political scientists.He tests three competing theories—realism, misperception, and domestic coalition politics—against five detailed case studies: early twentieth-century Germany, Japan in the interwar period, Great Britain in the Victorian era, the Soviet Union after World War II, and the United States during the Cold War. The resulting insights run counter to much that has been written about these apparently familiar instances of empire building.
