Social Theory of International Politics

Alexander Wendt

Constructivism / international relations

The founding theoretical statement of constructivism, the major alternative to realism and liberalism in international relations. Wendt's famous claim — 'anarchy is what states make of it' — holds that the international system's effects are not fixed by material structure but constituted by shared ideas, identities, and norms. The same anarchy can produce a war of all against all or a peaceful community, depending on how states understand themselves and each other. Essential for any complete picture of how world politics works.

About the author

American political scientist (b. 1958), professor at Ohio State University and the foremost theorist of constructivism in international relations. His 1992 article 'Anarchy Is What States Make of It' and the 1999 Social Theory of International Politics established constructivism as the major alternative to realism and liberalism in the field.

Synopsis

Wendt argues that the structures of international politics are social, not merely material: states' identities and interests are constructed through interaction, shared ideas, and norms rather than given by anarchy. He distinguishes Hobbesian, Lockean, and Kantian 'cultures of anarchy' — enmity, rivalry, and friendship — and argues that the system can and does shift among them. International politics, in short, is what states collectively make it.

Core passage idea

Paraphrase · Modern copyrighted work

Wendt argues that 'anarchy is what states make of it' — the international system has no fixed logic of conflict, because states' identities and interests are constituted by shared ideas and can change, turning anarchy toward enmity, rivalry, or friendship.

By making the meaning of anarchy depend on shared ideas rather than material structure, Wendt opened space for change and agency that realism denies: the same world of sovereign states can become more peaceful or more violent depending on how they understand one another. It is the theoretical heart of constructivism.

To avoid a bubble

Pair with the realism of Waltz and Mearsheimer (which Wendt argues against) and with critics who contend that constructivism explains how interests are formed but underrates the brute material constraints — power, geography, weapons — that realists emphasize.

Reading note

Theoretically dense; the argument about cultures of anarchy and the social construction of interests is the core. Read it as the major constructivist alternative to Waltz and Mearsheimer, completing the realist–liberal–constructivist trio.

Best paired with

Kenneth Waltz, Theory of International Politics; Robert Keohane, After Hegemony.
