What were the key driving forces behind the establishment of International Relations as an academic discipline? Provide an analysis of the major historical events and intellectual developments that contributed to its evolution and formal recognition.

Introduction

Diplomacy, war and treaties are as old as states, and thinkers from Kautilya and Thucydides to Machiavelli and Hobbes wrote about them. Yet International Relations (IR) became a separate academic discipline only in the twentieth century, in response to a specific historical shock and a desire to make the study of world politics systematic.

Driving force: the First World War

The First World War (1914–18) killed millions and destroyed empires. Many believed it was caused by secret diplomacy, alliances, arms races and the balance of power. Scholars and statesmen concluded that war must be studied scientifically so that it could be prevented. This normative purpose — preventing war — was the main driving force behind the new discipline.

Formal birth

In 1919 the Woodrow Wilson Chair of International Politics was established at the University College of Wales, Aberystwyth, funded by David Davies — widely regarded as the founding of IR as an academic discipline. Institutions followed: the Royal Institute of International Affairs (Chatham House) in London (1920), the Council on Foreign Relations in New York (1921) and new departments in the US and Europe.

The idealist phase

Early IR was dominated by liberal idealism, inspired by Woodrow Wilson's Fourteen Points. Idealists believed that international law, democracy, free trade, disarmament and collective security through the League of Nations could abolish war. Norman Angell's argument that war is economically irrational was influential.

The First Great Debate

The League's failure to stop aggression in Manchuria, Ethiopia and Europe, and the outbreak of the Second World War, discredited idealism. *E. H. Carr's The Twenty Years' Crisis* (1939) criticised "utopianism" and emphasised power. After 1945, Hans Morgenthau's Politics Among Nations (1948) established realism** as the dominant paradigm, focusing on national interest defined as power.

Cold War and the Second Debate

The Cold War and nuclear weapons made IR a major field, especially in the United States, with strategic studies, deterrence theory and foreign-policy analysis. In the 1950s–60s, the behavioural revolution sought to make IR more scientific through quantitative methods, opposed by traditionalists such as Hedley Bull who defended historical and philosophical approaches.

Later debates

In the 1970s–80s, neorealism (Kenneth Waltz, 1979) and neoliberal institutionalism (Keohane) dominated the "neo-neo" debate, while interdependence theory and Marxist dependency approaches highlighted economics. The Third Debate (late 1980s) challenged positivism through critical theory, postmodernism and feminism.

Post-Cold War expansion

The unexpected end of the Cold War encouraged constructivism (Alexander Wendt), which stresses ideas, identities and norms. IR expanded to globalisation, human security, environment and terrorism. Recently, scholars have called for non-Western and Global IR, drawing on Chinese, Indian and Islamic traditions, to correct the discipline's Eurocentric origins.

Conclusion

IR was born from the trauma of the First World War and a hope of preventing war, formally recognised with the Aberystwyth chair in 1919. Its evolution through great debates — idealism and realism, traditionalism and behaviouralism, positivism and post-positivism — mirrors the major events of the twentieth century. Today it is a pluralistic discipline seeking to understand an increasingly complex world.
