This is the first book in international relations theory entirely devoted to the political thought of Reinhold Niebuhr. Focusing on the existential theology which lies at the basis of Reinhold Niebuhr’s theory of international politics, it highlights the ways in which Niebuhrian realism was not only profoundly theological, but also constituted a powerful existentialist reconfiguration of the Realist tradition going back to Saint Augustine. Guilherme Marques Pedro offers an innovative account of Reinhold Niebuhr’s eclectic thought, branching out into politics, ethics, history, society and religion and laying out a conceptual framework through which his work, as much as the realist tradition of international political thought as a whole, can be read. The book calls for the need to revisit classic thinkers within IR theory with an eye to their interdisciplinary background and as a way to remind ourselves of the issues that were at stake within the field as it was growing in autonomy and diversity – issues which remain, regardless of its disciplinary development, at the core of IR’s concerns. This book offers an important contribution to IR scholarship, revealing the great historical wealth, intellectual originality but also the limitations and paradoxes of one of the greatest American political thinkers of the twentieth century.

Reinhold Niebuhr rose to prominenece in the 1930s and 1940s for his vociferous opposition both to Nazism and to isolationism as an American response to that threat. He rejected both pacifism and the legalism of the just war tradition. His pragmatic and realist approach to the ethics of force eschews absolute rules or restrictions. The work examines Niebuhr's consequentialist approach to ethics and war from the perspective of political theory.

The 1954 Conference on Theory, sponsored by the Rockefeller Foundation, featured a 'who's who' of scholars and practitioners debating what would become the foundations of international relations theory. Assembling his own team of experts, the editor revisits a seminal event in the discipline.

"Reinhold Niebuhr (1892-1971) may have been the most influential and insightful American thinker of the twentieth century. In dealing with the intricacies of human nature, society, politics, ethics, theology, racism and international relations, Niebuhr the teacher, preacher, philosopher, social critic and ethicist, was highly influential and difficult to ignore during the Second World War and Cold War eras because of his intellectual heft and the novel manner in which he addressed the economic, spiritual, social and political problems of his time. This book distils Niebuhr's disparate and now difficult to access work into one volume, making it more easily accessible than ever before, at the same time bringing his work into the twenty first century. It argues that if he were alive today Niebuhr would be a champion of the U.N, a supporter of globalization, a fierce opponent of America's 2003 Iraq War (for all the reasons he opposed the Vietnam War), an advocate of the Responsibility to Protect, and a pragmatic hawk on China as it rises today. It also highlights his many contributions to international relations theory, from Realism to Liberalism to existentialism to the English School to constructivism. This is the first book that focuses exclusively on the international relations thought of Reinhold Niebuhr, one of Classical Realism's most important figures, one whom diplomat and Realist George Kennan called, "the father of us all.""--
