CSS/PMS Political Science | Anarchy (IR): Absence of a Central World Government
Anarchy defines the global system as lacking a central world government to enforce rules among sovereign states; consequently, in CSS and PMS Political Science, it is the foundational framework for analyzing state survival, security dilemmas, and power balances.

Introduction
In the study of international relations, anarchy serves as the foundational ordering principle that defines the structural environment in which states operate. Unlike domestic political systems, where a central government holds a monopoly on the legitimate use of force and enforces laws, the international system is characterized by the absence of a superior authority. This structural condition creates a horizontal order where sovereign states are the primary actors, each responsible for its own survival and security. Understanding anarchy is essential for analyzing global politics, as it explains the underlying logic behind state competition, alliance building, and the persistent challenge of achieving lasting peace.
Definition
Anarchy is formally defined as the lack of a central governing body or a formal hierarchy within the international system. In this context, the term does not imply chaos, disorder, or a total lack of rules, but rather the absence of a world government that can dictate the behavior of sovereign nations.
According to Prominent theorist, Kenneth Waltz:
“Anarchy is a decentralized system where states are co-equal units in a legal sense, though they differ in material power.”
Essentially, anarchy is the structural reality that exists when there is no supreme power to act as a judge or a provider of security for independent nations.
Likewise, Robert Jervis, in his writings “Anarchy under the Security Dilemma (1978)” says:
“Anarchy is the characteristic of international politics that there is no government over governments.”
Meaning
The meaning of anarchy revolves around the concept of a self-help system, where states must prioritize their own national interests because they cannot rely on any higher authority for protection. This creates an environment of perpetual uncertainty, leading to what is known as the security dilemma. When one nation increases its military capabilities for purely defensive purposes, neighboring states often perceive this as a potential threat and respond by increasing their own military strength, as described by Morgenthau in his theory of the Balance of Power. He argued in Politics among Nations that skillful diplomacy drawing on these principles could lead to stability via the balance of power. Consequently, anarchy forces states to focus on the balance of power, as the lack of a global enforcer makes every nation ultimately responsible for its own preservation in an unpredictable world.
Characteristics
The anarchic international system is characterized by four main features: the absence of Central Authority, Self-Help System, Sovereignty, and Rational Actors, each of which is discussed in detail in the following paragraphs.
Absence of Central Authority
The most significant characteristic of anarchy is the total lack of a world government or a global sovereign that sits above individual states. This ensures that no entity has the legal or practical power to mandate laws or enforce compliance on a global scale. Without a central ruler, the international system remains a collection of independent units that interact based on their own goals rather than according to the dictates of a superior.
The Self-Help Principle
Because there is no global provider of security, states must operate on a principle of self-help to ensure their survival. This means that every nation is responsible for its own defense, economic stability, and diplomatic standing. In an anarchic system, states view self-reliance as a necessity, leading them to build up military forces and seek strategic resources to avoid becoming vulnerable to the ambitions of others.
Sovereignty of States
Sovereignty acts as a defining feature of the anarchic order, as it recognizes each state as the final authority within its own borders. This recognition prevents any external actor from legally intervening in the domestic affairs of a nation without its consent. By reinforcing the idea that no state is subordinate to another, sovereignty perpetuates the horizontal and anarchic nature of the international system.
Rational Actor Behavior
Under the pressure of anarchy, states are assumed to act as rational entities that calculate risks and benefits to ensure their longevity. Their primary goal is the pursuit of national interest, which usually begins with the maintenance of security and territorial integrity. This rational focus on survival drives much of the behavior seen in global politics, from the formation of military alliances to the pursuit of economic dominance.
Historical facts
The history of international anarchy is often traced back to the Peace of Westphalia in 1648, which officially established the modern state system by ending the era of imperial and religious over-lordship. This period marked the transition from a hierarchical European order to one composed of independent and co-equal sovereign states. Meanwhile, the eventual failure of the League of Nations in the early 20th century reflected the lack of a common power. Its real manifestation is the Cold War era, when the United States and the Soviet Union engaged in a massive arms race because neither side could rely on an international body to guarantee their safety. This has further reinforced the Realist view that international organizations often struggle to overcome the structural reality of anarchy when great powers pursue their own survival.

Contemporary Relevance
Anarchy remains highly relevant in the modern era as is manifested below.
Ukraine-Russia War (The Failure of Collective Security)
Anarchy acts as the “permissive cause” of war because there is no world police to physically stop an aggressor.
- The Conflict: Despite the International Court of Justice ordering Russia to halt its invasion and the UN General Assembly condemning it, the war continues.
- The Anarchic Reality: Because Russia holds a veto on the UN Security Council, the central organ for global peace is paralyzed. Ukraine must rely entirely on a “self-help” strategy, utilizing its own military and Western alliances to survive.
Middle East Escalation (The Security Dilemma)
In an anarchic system, one state’s defensive actions are viewed as an existential threat by its neighbors, triggering a spiral of violence.
- The Conflict: The direct military strikes between Israel and Iran, alongside conflicts involving Hezbollah and the Houthis, have bypassed international mediation.
- The Anarchic Reality: International law and UN resolutions have failed to deter escalation. Lacking a global authority to guarantee their security, both state and non-state actors prioritize unilateral, survival-driven military power over diplomatic treaties.
The South China Sea Disputes (Power Trumps International Law)
Without a centralized authority to enforce judicial rulings, powerful states can ignore international legal structures with impunity.
- The Conflict: China claims vast maritime territory in the South China Sea, directly overlapping with the exclusive economic zones of smaller nations like the Philippines and Vietnam.
- The Anarchic Reality: An international tribunal ruled against China’s claims in favor of the Philippines. However, because there is no global enforcement mechanism, China ignored the ruling and expanded its military presence, forcing smaller nations to seek counter-balancing naval alliances with the United States.

Conclusion
In conclusion, anarchy is the structural foundation of international relations that dictates how states perceive and respond to the world around them. While it does not make conflict inevitable, it creates a self-help environment that prioritizes security and survival above all else. Liberal scholars argue that international institutions can help mitigate the effects of anarchy through cooperation, while Realists maintain that the lack of a central authority will always lead to power struggles. Ultimately, anarchy is the defining characteristic of our global system, ensuring that the quest for national interest remains the driving force behind the actions of every sovereign state.
Key Takeaways
- Structural Concept: Anarchy refers to the lack of a central world government, not social chaos.
- Security Dilemma: The absence of a global enforcer leads states to arm themselves, often causing mutual suspicion.
- Self-Help System: Nations must rely on their own resources and alliances to ensure their survival.
- Ordering Principle: Anarchy is the fundamental condition that distinguishes international politics from domestic politics.
