What structural and historical factors explain the continued primacy of the sovereign state as the principal actor in international relations? Contrast realist, liberal, and constructivist explanations of state primacy in international relations.

Introduction

The continued primacy of the sovereign state as the principal actor in international relations constitutes one of the most enduring structural features of global politics, despite recurrent predictions of its erosion in the face of globalization, transnational networks, supranational governance, and non-state actors. From the Treaty of Westphalia (1648) to the contemporary multipolar order, the sovereign state has retained its institutional centrality as the locus of authority, legitimacy, coercion, and diplomatic representation.

This persistence invites deeper analytical interrogation: What structural and historical forces have sustained state primacy? Why have alternative actors—corporations, international organisations, epistemic communities, or civil society networks—not displaced the state as the core unit of international order? Addressing these questions requires engagement with competing theoretical traditions—Realism, Liberalism, and Constructivism—each of which offers distinct ontological and epistemological explanations for the endurance of the sovereign state.


I. Historical Foundations of State Primacy

1. Westphalian Institutionalisation of Sovereignty

The Peace of Westphalia codified three foundational principles:

  • Territorial sovereignty
  • Non-intervention
  • Juridical equality of states

While historians debate the “myth of Westphalia,” its symbolic and institutional significance lies in the consolidation of territorialised political authority as the organizing principle of international order.

This transformed medieval pluralism—where papacy, empire, and feudal authorities overlapped—into a system of mutually recognised sovereign units.


2. State Formation and War-Making

Charles Tilly’s classic formulation—“war made the state, and the state made war”—highlights coercion as central to state consolidation.

Structural drivers included:

  • Standing armies
  • Fiscal extraction systems
  • Bureaucratic centralisation
  • National identity formation

War thus privileged territorially bounded actors capable of mobilising resources at scale—advantages non-state entities could not replicate.


3. Colonial Expansion and Globalisation of the State Form

European imperialism exported the state model globally.

Decolonisation did not dismantle this structure; instead, newly independent polities adopted:

  • Sovereign territorial borders
  • Diplomatic recognition regimes
  • UN membership

Thus, the state form became universalised rather than regional.


4. Legal–Institutional Entrenchment

Modern international law is structurally state-centric:

  • Treaty-making authority rests with states.
  • Diplomatic recognition is state-mediated.
  • International courts operate via state consent.

Even global governance institutions—UN, WTO, IMF—derive authority from member states.


II. Structural Drivers of Continued State Primacy

Despite globalisation, several structural factors reinforce state centrality:

1. Monopoly over Legitimate Violence

Following Weber, the state retains the exclusive claim to legitimate coercion within territory.

Private military actors, militias, or insurgents lack:

  • Legal legitimacy
  • Diplomatic standing
  • Institutional continuity

Security remains the most “state-dependent” domain.


2. Territorial Governance and Citizenship

States regulate:

  • Borders
  • Migration
  • Citizenship rights
  • Welfare distribution

No alternative actor possesses comparable jurisdictional authority.


3. Resource Mobilisation Capacity

Taxation, monetary policy, and fiscal redistribution remain state prerogatives—even under neoliberal globalisation.


4. Crisis Governance

Pandemics, wars, and financial crises repeatedly demonstrate the state’s irreplaceability in:

  • Emergency legislation
  • Economic bailouts
  • Public health enforcement

COVID-19 reaffirmed the resilience of territorial governance.


III. Realist Explanations of State Primacy

Realism provides the most categorical defence of state centrality.

Ontological Premise

The international system is anarchic—lacking overarching authority. In such a system, survival becomes the primary goal.

Structural Arguments

1. Security Dilemma
States must rely on self-help; non-state actors cannot guarantee security.

2. Power Aggregation
Military capability requires centralised authority and resource extraction.

3. Strategic Rationality
States function as unitary actors pursuing national interest.

Kenneth Waltz’s structural realism posits that the distribution of capabilities among states defines systemic order; thus, only states count structurally.


Historical Evidence

  • Balance-of-power politics
  • Alliance systems
  • Nuclear deterrence

All operate through sovereign state agency.


Critique

Realism underestimates:

  • Institutional constraints
  • Norm diffusion
  • Transnational influence

Yet its explanatory power remains strongest in high politics (security, war).


IV. Liberal Explanations of State Primacy

Liberalism does not deny state centrality but situates it within institutional and interdependence frameworks.

Core Claims

1. States as Primary but Not Exclusive Actors
International organisations and corporations matter but operate through state delegation.

2. Institutional Embeddedness
Institutions reduce transaction costs and facilitate cooperation but depend on state participation.

Robert Keohane’s neoliberal institutionalism argues institutions are state-created governance mechanisms, not sovereign substitutes.


Economic Interdependence

Global markets constrain states but do not eliminate them:

  • Trade agreements are state-negotiated.
  • Sanctions are state-imposed.
  • Currency regimes are state-managed.

Thus, interdependence modifies but does not displace sovereignty.


Democratic Peace Thesis

Liberals maintain that regime type shapes state behaviour, but the state remains the operative unit.


Critique

Liberals may overstate institutional autonomy; power asymmetries among states still shape institutional outcomes.


V. Constructivist Explanations of State Primacy

Constructivism shifts analysis from material structures to ideational and normative foundations.

State as Social Institution

Alexander Wendt famously argued: “Anarchy is what states make of it.”

State primacy persists because:

  • Sovereignty is socially recognised.
  • Diplomatic practices reproduce state legitimacy.
  • International law normalises statehood.

Normative Institutionalisation

Key norms sustaining state centrality include:

  • Territorial integrity
  • Self-determination
  • Non-intervention

Even humanitarian interventions require justificatory engagement with sovereignty norms.


Identity and Recognition

States function as identity-bearing actors:

  • National narratives
  • Civilizational claims
  • Historical memory

Recognition politics reinforces state legitimacy internationally.


Constructivist Insight

The state persists not only because of power but because the international system is cognitively organised around statehood.

VII. Why the State Has Not Been Displaced

Synthesising theoretical insights, state primacy persists due to:

  1. Coercive centralisation (Realism)
  2. Institutional delegation authority (Liberalism)
  3. Normative legitimacy and recognition (Constructivism)

Non-state actors influence outcomes but lack:

  • Territorial jurisdiction
  • War-making authority
  • Diplomatic sovereignty

Thus, they operate within—not above—the state system.


VIII. Emerging Challenges but Persistent Core

Challenges

  • Transnational terrorism
  • Multinational corporations
  • Climate governance
  • Digital sovereignty

Persistence Indicators

  • Border enforcement resurgence
  • Economic nationalism
  • Military modernisation
  • Vaccine nationalism

Even globalization’s crises have reinforced state authority rather than dissolved it.


Conclusion

The continued primacy of the sovereign state in international relations is neither accidental nor merely residual; it is structurally reproduced through coercive capacity, institutional architecture, and normative legitimacy. Historically forged through war-making, colonial expansion, and legal codification, the state form has become universalised as the organising unit of global politics.

Realists explain this persistence through the imperatives of survival and power aggregation under anarchy. Liberals emphasise the state’s role as institutional architect and manager of interdependence. Constructivists, meanwhile, highlight the ideational reproduction of sovereignty norms and recognition practices that sustain state legitimacy.

Together, these perspectives reveal that while globalisation has pluralised actors and diffused power, it has not displaced the sovereign state. Rather, the international system remains a state-centric order embedded within multi-actor complexity—a layered architecture where sovereignty endures as both structural necessity and social institution.
