Overview

The rules binding states together are not the whole story of global order. Something larger is taking shape.

The English School gave international relations one of its most enduring frameworks. But its core concepts were forged when states dominated the landscape almost completely.

Buzan's project is renovation, not demolition. He keeps the tradition's strengths while forcing it to reckon with what it has long underexplored.

Three societies, not one

  • International system: states interacting through power and interest
  • International society: states bound by shared rules and institutions
  • World society: non-state actors, individuals, and humanity as a whole

World society was always the neglected concept.

Globalisation presses world society from the margins to the center. Rethinking the concept is no longer optional for anyone serious about how global order actually works.

What is inside

Rethinking the English School

  1. 01The Classical English School and Its LimitsUse the English School's state-centric categories for interstate dynamics, but actively ask what they leave out before treating any analysis as complete.Below, in full
  2. 02Unpacking the Three Traditions: Hobbes, Grotius, KantWhen analysing any international dispute, name which of the three traditions is driving each actor's reasoning before evaluating the policy options.
  3. 03Revisiting the International Society ConceptMap every global issue across all three layers: interstate, transnational, and interhuman, before drawing conclusions about where norms come from.
  4. 04World Society as the Missing TermTreat world society as a distinct analytical tier, not a residual label for anything non-state.

Rebuilding the Conceptual Architecture

  1. 05Primary and Secondary Institutions of International SocietyWhen assessing any international norm or organisation, first ask whether it constitutes international society or merely regulates conduct within it.
  2. 06Levels of Analysis: Interstate, Transnational, InterhumanMap any global issue across all three layers before diagnosing where the problem or solution actually sits.
  3. 07Normative Structures and the Expansion of SocietyDistinguish compliance from internalization: a norm obeyed for strategic reasons is fragile; one genuinely internalized is durable.

Globalisation and the Future of World Society

  1. 08Globalisation as a Challenge to International Society TheoryAudit causal stories to check whether norms are driven by states or by transnational actors before assigning theoretical weight.
  2. 09Non-State Actors and the Pluralisation of World SocietyMap non-state actor coalitions early to anticipate where global norms are heading before states codify them.
  3. 10From International to World Society: A Revised Research AgendaTreat world society as a structured analytical domain with distinct actor types, not a catch-all for everything that is not a state.

The Classical English School and Its Limits

The English School built international relations theory on shared rules and norms among states, but its classical form left whole layers of global social life unnamed and unexamined.

A Framework With Blind Spots

The classical English School gave IR theory its most durable vocabulary: international system, international society, and the rules that states observe even without a world government enforcing them.

That vocabulary was powerful precisely because it took norms seriously. Where realism saw only power and interest, the English School saw diplomacy, international law, and shared institutions shaping state behaviour.

Why the Gaps Matter Now

Globalisation has filled the world with actors, networks, and loyalties that sit outside the state-to-state frame. When that frame is the only lens, those forces become invisible by definition, and theory loses its grip on reality.

This is not a minor omission. Transnational firms, global civil society, shared human rights norms, and cosmopolitan identities now shape outcomes that states cannot fully control or explain.

The Central Mechanism

The school organised its thinking around a single primary institution: the society of states. Everything else was either derivative of that or outside the frame entirely. The mechanism was elegant but narrow: norms matter, and the relevant norm-carriers are states.

A Concrete Illustration

Consider how the school handled human rights. It could describe treaties among states and the diplomatic norms surrounding them. It struggled to account for transnational advocacy networks pressuring governments from outside, or for individuals claiming rights against their own state. Those actors fit poorly in a state-centric frame.

The Most Important Takeaway

Recognising what a framework excludes is as important as mastering what it includes. The English School's categories are not wrong; they are incomplete. Knowing the boundary prevents the mistake of treating a partial map as a full one.

Deepening the Mechanism

The classical school distinguished three broad concepts: system, society, and community. But in practice, community, which would gesture toward shared values beyond state interest, was undertheorised and rarely operationalised.

International System
States interacting with regular, consequential effects on one another, without necessarily sharing values or rules.
International Society
States that share rules, norms, and institutions and treat each other as bound by them, the core ES concept.
World Society
The broader social space including non-state actors, individuals, and transnational groups, the concept the classical school left underdeveloped.
Primary Institutions
Deep, evolved practices like sovereignty, diplomacy, and the balance of power that define the society of states itself.

The distinction between international society and world society is the fault line Buzan presses on. Classical theorists named world society but did not build analytical tools for it. That gap is precisely where theory needs to grow to meet globalisation.

A Contrasting Case

Where the state-centric frame works well: great-power management of nuclear risks. States are the relevant actors, diplomacy is the medium, and shared norms about non-use are doing real work. The English School describes this excellently.

Where it fails: the governance of the internet. Technical standards bodies, private corporations, user communities, and states all shape outcomes. No single state-to-state norm structure governs the space. The classical frame has almost nothing useful to say.

DomainClassical ES StrengthClassical ES Weakness
Nuclear arms normsHigh: state actors, formal treaties, diplomatic practiceLow: little non-state pressure shapes core outcomes
Human rightsMedium: treaty law among states is coveredHigh: transnational advocacy, individual claims are outside the frame
Internet governanceLow: multi-stakeholder reality defies state-centric logicHigh: private and civil-society actors are primary drivers
Global tradeMedium: WTO as interstate institution fits the frameMedium: multinational firm power and consumer activism are undertheorised

Conditions That Stress the Framework

  • When non-state actors gain norm-setting power independent of states
  • When identities and loyalties form across borders outside state mediation
  • When enforcement of shared rules depends on civil society rather than interstate sanction
  • When the relevant community is humanity rather than a club of recognised states

These conditions are not rare edge cases. They describe large portions of contemporary global life. That is why updating the framework is urgent rather than merely academic.

Putting It Into Practice

  1. Map the actors: Before applying ES categories, list who is actually shaping the issue: states only, or also firms, NGOs, and individuals?
  2. Test the frame: Ask whether interstate norms are the primary mechanism at work, or whether other social logics are doing more of the explanatory labour.
  3. Name the gap: If non-state dynamics dominate, flag this as world-society terrain and look for complementary frameworks rather than forcing the state-centric model.
  4. Hold both layers: Use international-society analysis for the state layer and world-society concepts for the rest, keeping them in dialogue rather than collapsing one into the other.

Deeper Structure and Objections

At the deepest level, the classical school's limits are epistemological as well as empirical. Its foundational move was to treat the society of states as the relevant social whole. Once that move is made, other social formations appear only as inputs to or outputs from state behaviour.

Buzan's project is partly ontological: insisting that non-state actors, transnational networks, and individuals constitute genuine social structures in global politics, not just background noise around the main state-centric story.

Ontological Priority
The choice of which entities a theory treats as fundamental. The classical ES gave ontological priority to states.
Normative Cosmopolitanism
The view that moral obligations run to individuals and humanity, not only to co-members of a state, a view world-society concepts help capture.
Structural Pluralism
Recognition that global social life has multiple distinct layers, each with its own logic, none fully reducible to the others.

Edge Cases and Exceptions

The classical frame performs better than expected in situations where states remain the dominant mediators of transnational pressures. When a state successfully channels NGO activism into treaty negotiation, for example, the state-centric logic reasserts itself. The framework's weakness is not total; it is domain-specific.

Conversely, even within the state-centric frame, the classical school struggled with non-Western states and colonial history. Its primary institutions, sovereignty foremost, were historically defined by a club of European powers. Extending them universally introduced tensions the classical theorists did not fully resolve.

ObjectionReply
The ES already handles non-state actors through the concept of solidarismSolidarism adjusts the moral commitments of states; it does not give non-state actors independent analytical standing in the framework
World society is too vague to be useful analyticallyVagueness is a reason to develop the concept, not to abandon it; Buzan's project is precisely to give it analytical structure
Expanding the frame risks losing the ES's distinctive contributionThe goal is a layered framework that preserves interstate-society analysis while adding complementary tools, not replacement
Non-state actors ultimately depend on state permission to operateEmpirically contested: many transnational networks set norms that states then adopt, reversing the direction of causation

Second-Order Implications

  • If world society is analytically real, then international society is one layer of a larger whole, not the whole itself, which reframes the entire ES research programme.
  • Legitimacy in global governance increasingly requires world-society consent, not just interstate agreement, which changes how we evaluate international institutions.
  • The tension between state-centric and world-society logics is itself a political force: actors exploit the gap strategically, claiming state authority when convenient and transnational legitimacy when not.
  • Theories that ignore world society will systematically misread who is setting the agenda in global politics, producing blind spots with real policy consequences.

The classical English School remains indispensable for understanding the architecture of interstate order. Its limits are not a reason to discard it but a spur to build on it. The most productive stance is neither wholesale adoption nor rejection, but disciplined extension.

Partial maps are dangerous only when mistaken for complete ones.
