A balanced reading path
Where to start with International order and realism
Nationhood, identity, sovereignty, and belonging.
Part of Nationalism. This path zooms in on international order and realism specifically.
What is international order and realism?
International realism holds that the fundamental structure of the international system is anarchy — there is no sovereign above states — and that this structural fact, not the goodness or badness of leaders, drives conflict and the pursuit of power. Realists disagree about whether this produces an inevitable logic of war (Waltz's structural realism), a pattern of great power competition (Mearsheimer), or merely a sphere of behaviour different from domestic politics (Morgenthau). All of them share a suspicion of idealism and a demand for foreign policy grounded in actual power relations rather than moral aspirations.
Waltz's Theory of International Politics is the canonical structural statement: states behave according to the anarchic structure of the system, not the character of their governments. Renan's What Is a Nation? steps back from international relations to the foundational question: what kind of entity is a state representing? Morgenthau's Politics Among Nations is the classical realist handbook — power, national interest, and the balance of power as the permanent features of international life. Kant's Perpetual Peace stands as the idealist counter: republican states can build a pacific federation and escape the war cycle. Carr's The Twenty Years' Crisis closes with the interwar demolition of liberal internationalism — and the argument that power and interest, not norms and institutions, determine outcomes.
The 5-book path
- 1Start Here— the accessible entry point
Theory of International Politics
Kenneth Waltz · Neorealism / international relations
The book that founded 'neorealism' and reshaped the academic study of international politics. Waltz argued that the behaviour of states is driven less by their internal character than by the structure of the international system itself — an anarchy with no overarching authority — which compels even peaceful states to compete for security. The most rigorous statement of structural realism, and the reference point for every later debate in the field.
To avoid a bubble: Pair with the liberal institutionalism of Robert Keohane (who argues cooperation can persist under anarchy) and the constructivism of Alexander Wendt ('anarchy is what states make of it'), both of which challenge Waltz's claim that structure determines so much.

What Is a Nation?
Ernest Renan · Nationalism
The single most influential short answer to the question the whole subject turns on: what actually makes a nation? Renan rejects race, language, religion, and geography as the basis of nationhood and argues instead that a nation is a spiritual principle — a shared inheritance of memory and a present-day will to live together. It is the founding text of the civic, as opposed to ethnic, conception of the nation, and the obvious place to begin.
To avoid a bubble: Pair with ethnic or romantic theorists of nationhood (Fichte, Herder) for the rival view that a nation is rooted in blood, language, and descent, and with Gellner or Anderson for the modern social-scientific account that treats nations as recent constructions.

Politics Among Nations
Hans Morgenthau · Classical realism / international relations
The foundational text of 20th-century IR realism. Morgenthau's argument that international politics is driven by interest defined as power — not by moral principles or international law — defined the discipline of international relations for decades and remains the primary reference point for both realist practitioners and liberal and constructivist critics.
To avoid a bubble: Pair with Kant's Perpetual Peace for the liberal-idealist counter-claim, and with E. H. Carr's The Twenty Years' Crisis for a more historically situated version of realism. Alexander Wendt's Social Theory of International Politics offers the constructivist response.
- 4Opposing View— the serious counter-argument, to avoid a bubble
Perpetual Peace
Immanuel Kant · Liberal internationalism
A foundational liberal text on peace, republican government, cosmopolitan right, and international order.
To avoid a bubble: Pair with realist critiques of international politics.
- 5Contemporary Lens— a current-day perspective
The Twenty Years' Crisis
E. H. Carr · International relations realism
A foundational realist critique of utopianism in international politics.
To avoid a bubble: Pair with liberal internationalism or democratic peace theory.
