The IR Reading List
Fifteen books every international relations student should know — from the foundational texts of IR theory to accessible reads that make geopolitics come alive. Every recommendation is genuine. Every book earns its place.

How these books were chosen
This is not a list of every important IR book ever written — it is a list of books that I think are genuinely worth your time at different stages of studying international relations. The theory texts are the ones you will encounter in every serious IR programme. The accessible reads are the ones I recommend to anyone who wants to understand the world without wading through academic jargon. Five of these I have read personally and marked accordingly.
📚 IR Theory — The Canon
6 books
Politics Among Nations
The foundational text of classical realism. Morgenthau’s argument that international politics is governed by the pursuit of national interest defined in terms of power remains the starting point for every IR theory course. He argues that statesmen who forget this — who pursue idealistic goals without regard for power — consistently fail. Even if you disagree with realism, you must understand Morgenthau before you can argue against him.
Why it matters Every IR theory course begins here. Morgenthau defines the terms — power, national interest, balance of power, statecraft — that all subsequent IR theory engages with. Non-negotiable reading.
Theory of International Politics
The most influential IR theory book of the twentieth century. Waltz’s structural realism — the argument that the distribution of power in the international system explains state behaviour better than human nature or domestic politics — is the baseline theory that every subsequent theorist has had to engage with. Dense but essential. Read it slowly.
Why it matters Waltz invented a way of thinking about international politics that changed the discipline permanently. Defensive realism, offensive realism, neoclassical realism — all of them begin with Waltz, either building on him or arguing against him.
After Hegemony: Cooperation and Discord in the World Political Economy
The foundational text of neoliberal institutionalism. Keohane asks: if realists are right that states are self-interested, why do international institutions exist and why do states follow their rules? His answer — that institutions reduce transaction costs and enable mutually beneficial cooperation even without a hegemon — is the liberal response to realist scepticism about international organisations.
Why it matters Essential for understanding the WTO, IMF, UN, and every multilateral institution. When realists say institutions are irrelevant and liberals say they matter, Keohane is what liberals are defending.
Social Theory of International Politics
The foundational text of constructivism. Wendt’s argument that “anarchy is what states make of it” — that the competitive, self-help character of the international system is a social construction rather than an objective structural fact — transformed IR theory. States’ identities and interests are not fixed but shaped by interaction, norms, and shared understandings. Dense but worth the effort.
Why it matters Constructivism is now one of the three dominant IR theories alongside realism and liberalism. Wendt is the scholar who made it theoretically rigorous enough to be taken seriously by positivist IR scholars.
