A VCE Politics Unit 3 answer on the state and sovereignty. Defines statehood and its four characteristics, explains internal and external sovereignty, and assesses how globalisation, intervention and supranational bodies challenge state sovereignty, with current examples such as Russia, China and the European Union.

What this dot point is asking
VCAA wants you to define the state, list the characteristics that make an entity a state, and explain what sovereignty means and why it matters. You also need to judge how secure sovereignty really is, because exam questions often ask you to analyse the extent to which state sovereignty is being eroded or reinforced in contemporary global politics. A strong answer separates the legal idea of sovereignty from the practical capacity of a state to act on it.
The answer
What is a state?
A state is a political and legal entity that governs a defined territory and population. Under the widely cited Montevideo criteria, an entity qualifies as a state when it has four characteristics: a permanent population, a defined territory, a government, and the capacity to enter into relations with other states. States are the primary actors in global politics because only they hold sovereignty.
It is worth distinguishing the state from the nation and the government. A nation is a group bound by shared identity, culture or history; a government is the body that exercises authority on behalf of the state at a given time. The state endures even when governments change.
Internal and external sovereignty
Sovereignty is supreme authority. It has two faces.
- Internal sovereignty. The state holds final authority over everything within its borders, including the sole legitimate use of force, the power to make and enforce law, and control over its population and resources.
- External sovereignty. Other states recognise the state as legally equal and independent, free from outside interference. This is captured in the United Nations Charter principle of the sovereign equality of members.
Sovereignty matters because it is the organising principle of the international system. It underpins non-intervention, territorial integrity and the legal equality of states regardless of size. Without it, there is no agreed basis for borders, treaties or membership of organisations.
Challenges to sovereignty
Although sovereignty remains the foundation of the system, its practical force is contested.
- Globalisation. Cross-border flows of trade, finance, people, information and disease reduce a state's ability to control what happens inside its borders. A government cannot fully insulate its economy from a global financial shock or its population from online information.
- Supranational bodies. When states join organisations they pool some authority. European Union members accept that EU law overrides national law in many areas and that the European Court of Justice can bind them, a voluntary but real constraint on internal sovereignty.
- Intervention and the responsibility to protect. The doctrine that the international community may act when a state fails to protect its population from mass atrocities challenges the older norm of absolute non-intervention.
- Powerful non-state actors. Transnational corporations, armed groups and terrorist organisations can operate across or inside borders in ways that states struggle to control.
Sovereignty reasserted
The erosion thesis can be overstated. States still guard sovereignty fiercely. Russia justified its 2022 invasion of Ukraine partly in the language of security and spheres of influence, while Ukraine has defended its territorial sovereignty with international backing. China insists that Taiwan and the South China Sea are matters of internal sovereignty and rejects outside comment. The COVID-19 pandemic saw states close borders and act unilaterally, showing that in a crisis sovereignty snaps back into focus.
Examples in context
Example 1. Pooled sovereignty in the European Union. Member states accept that EU law overrides national law and that EU institutions can bind them. This is a deliberate surrender of slices of internal sovereignty in exchange for the benefits of the single market, showing sovereignty can be shared by choice.
Example 2. Sovereignty defended by force. Russia's 2022 invasion of Ukraine was a direct assault on Ukrainian external sovereignty and territorial integrity. Ukraine's resistance, backed by Western military and financial support, illustrates how central sovereignty remains and how violently it can be contested.
Try this
Q1. Define sovereignty and distinguish its internal and external dimensions. [4 marks]
- Cue. Supreme authority; internal is final control within borders, external is recognised legal equality and independence.
Q2. Explain two ways state sovereignty is challenged in contemporary global politics. [6 marks]
- Cue. Choose from globalisation, supranational bodies, the responsibility to protect, or powerful non-state actors, each with an example.
Q3. Analyse the extent to which state sovereignty has been eroded. [10 marks]
- Cue. Weigh erosion (EU, globalisation, intervention) against reassertion (Russia, China, COVID border closures) and reach a defensible judgement.
Exam-style practice questions
Practice questions written in the style of VCAA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
2022 VCAA2 marksOutline how a nation differs from a state.Show worked answer →
Two marks, so make two clear distinctions, ideally one defining each term.
A state is a legal and political entity: a defined territory, a permanent population, a government and the capacity to enter relations with other states. Sovereignty is its defining feature.
A nation is a community of people bound by shared identity, such as common culture, language, history or ethnicity. It is a sociological idea, not a legal one, and need not have territory or sovereignty.
The key point for the second mark is that the two can come apart: a state may contain several nations (for example, multi-ethnic Indonesia), and a nation may have no state of its own (for example, the Kurds, spread across several states). Markers reward showing that statehood is about legal sovereignty while nationhood is about shared identity.
2021 VCAA2 marksExplain why maintaining sovereignty is an important aim of states.Show worked answer →
For 2 marks give the meaning of sovereignty and one clear reason it matters.
Sovereignty is supreme authority within a state's borders and legal equality with other states. It means no outside actor may lawfully dictate what happens inside the territory.
It is an important aim because sovereignty is what guarantees a state's independence and survival: it lets the government control its own laws, security and resources free of external command, and underpins the principle of non-intervention that protects weaker states from stronger ones. Without sovereignty a state cannot secure its other national interests, so defending it is foundational.
2020 VCAA4 marksExplain how a specific action by a regional grouping has challenged the sovereignty of a state.Show worked answer →
Four marks: name a specific regional grouping, name a specific action, and explain clearly how that action eroded a state's supreme authority within its borders.
A strong example is the European Union. By joining, member states transfer authority to supranational bodies whose law overrides national law. A concrete action is the European Court of Justice issuing binding rulings, or the EU setting common rules on trade, borders or budgets that a member must obey even against its own preference.
The challenge to sovereignty: the state can no longer make the final decision in these policy areas, because EU law has primacy and is enforced by EU institutions. The Greek debt crisis, where EU and creditor conditions dictated Greek budget policy, shows a member's internal economic sovereignty being constrained from outside.
Markers want a real grouping, a real action, and an explicit link to the loss of final authority. A defensible point is that this is a voluntary, partial surrender of sovereignty, not its abolition.
