1.2 Defining Political Organizations
State, nation, regime and government sound alike but mean different things, and the exam tests the difference constantly. A government changes often; a regime changes rarely; a state can last centuries; a nation is about identity, not borders.
Key terms
- state
- nation
- regime
- government
- sovereignty
- nation-state
Four terms, four meanings
- State: a political unit with a permanent population, defined territory, a government and sovereignty. The UK, Mexico, Russia, Iran, China and Nigeria are all states.
- Sovereignty: the final authority to make and enforce rules inside a territory, without outside control. Internal sovereignty is control at home; external sovereignty is recognition by other states.
- Nation: a group of people who see themselves as sharing an identity, such as language, history, religion or culture, and often want to govern themselves. A nation is about how people feel, not where borders are drawn.
- Regime: the basic rules of the game for how power is gained and used, often written in a constitution. Examples: a liberal democracy, a theocracy, a one-party state.
- Government: the specific people and party running the state right now, such as the current prime minister and cabinet.
Nation-states and multinational states
A nation-state is a state whose people mostly share one national identity. Few states fit this perfectly. A multinational state contains several nations. The UK is made up of England, Scotland, Wales and Northern Ireland, and many Scots see themselves as a separate nation. Nigeria has more than 250 ethnic groups, Russia has more than 20 ethnically based republics, and China officially recognizes 55 minority groups alongside the Han majority.
A nation can also exist without its own state. The Kurds, for example, live across Iran, Iraq, Turkey and Syria.
Government change vs. regime change
This is the distinction the exam loves. When the UK's Conservative government lost the 2024 general election and Labour took over, the government changed but the regime (parliamentary democracy under an uncodified constitution) stayed the same.
A regime change rewrites the rules themselves. Iran in 1979 moved from a monarchy under the Shah to an Islamic Republic. Russia moved from the Soviet one-party system to a new constitution in 1993. Nigeria moved from military rule to an elected civilian government under the 1999 constitution. In each case the state (the country, its territory and its sovereignty) carried on.
| Change | What changed | Level |
|---|---|---|
| UK, 2024 election | Labour replaced the Conservatives in government | Government |
| Iran, 1979 revolution | Monarchy replaced by an Islamic Republic | Regime |
| Nigeria, 1999 | Military rule replaced by elected civilian rule | Regime |
| Mexico, 2000 election | The PAN replaced the PRI after 71 years | Government, and a step in a longer regime change toward democracy |

- Example 1
Classifying a change
A country's military removes the elected president, suspends the constitution and rules by decree through a council of officers. Identify whether this is a change of government, regime or state, and explain.
Show the solutionHide the solution
- Step 1: Ask what changed: only the people in charge, the rules for gaining and using power, or the country's borders and sovereignty?
- Step 2: Here the constitution is suspended and power now comes from the military, not elections. The rules of the game changed.
- Step 3: The territory and sovereignty stay the same, so the state hasn't changed.
Answer: A regime change, because the basic rules for holding power changed from elections under a constitution to military decree, while the state itself continues.
Common mistakes
- Using “nation” and “state” as if they mean the same thing. A state is a legal and political unit; a nation is a shared identity.
- Calling every election that changes the ruling party a regime change. That's a change of government.
- Forgetting that a state needs sovereignty. A region with its own government but no final authority, like Scotland, is not a state.
On the exam
- Expect multiple-choice questions that describe a scenario and ask which term fits. Look for whether the rules, the people or the territory changed.
- The conceptual analysis free-response question often starts by asking you to define a term like regime or sovereignty. Give a precise one-sentence definition before you explain.
