States, Sovereignty & Legitimacy

You’ll be able to

State, nation, regime, government

Comparative politics rests on four distinct terms. A state is a territory with a permanent population and a government that holds sovereignty — supreme authority within its borders. A nation is a group united by shared identity (language, culture, history), which may or may not match state borders. A regime is the enduring set of rules and institutions that organize power — it outlasts any single leader. A government is the particular set of officials in power at a given moment. Nigeria, for example, is one state containing many nations; its regime is a federal presidential democracy, while its government changes with each election.

Sovereignty: unitary vs. federal

How a state distributes sovereignty internally varies. In a unitary state, power is concentrated in the central government, which may delegate authority but can also reclaim it — the United Kingdom, China, and Iran are unitary. In a federal state, sovereignty is constitutionally divided between the national government and regional units — Russia, Mexico, and Nigeria are federal, with states or regions holding their own powers. Devolution (as in the UK’s transfer of powers to Scotland and Wales) grants regional autonomy without turning a unitary state into a truly federal one, because the center can, in principle, take the powers back.

Three sources of legitimacy

Max Weber identified three bases of legitimacy — the right to rule that citizens accept. Traditional legitimacy rests on custom and long-standing practice (the UK monarchy; Iran’s clerical authority draws on religious tradition). Charismatic legitimacy rests on the personal appeal of a leader (a revolutionary founder like Iran’s Ayatollah Khomeini). Rational-legal legitimacy rests on established laws and procedures — citizens obey the office, not the person (the UK’s parliamentary rule of law; Mexico’s constitutional elections). Regimes often blend all three, and a loss of legitimacy is a warning sign of instability.

Worked example

Iran’s Supreme Leader claims authority both as heir to a revolution led by a charismatic founder and as the embodiment of religious tradition, while also operating within a written constitution. Classify the sources of legitimacy at work and explain why a regime might rely on more than one.

  1. 1.Identify the religious/customary basis: authority rooted in Shia Islamic tradition and clerical rule reflects traditional legitimacy.
  2. 2.Identify the founder’s appeal: the regime traces itself to Ayatollah Khomeini, whose personal, revolutionary authority reflects charismatic legitimacy.
  3. 3.Identify the procedural basis: operating through a written constitution, elected bodies, and formal offices reflects rational-legal legitimacy.
  4. 4.Explain the blend: relying on several sources makes rule more durable — if one basis weakens (charisma fades after a founder dies), the others can sustain the regime.
Answer: Iran blends all three Weberian sources: traditional (clerical/religious authority), charismatic (the revolutionary founder Khomeini), and rational-legal (a written constitution and formal offices). Regimes combine sources because it makes legitimacy more resilient — charismatic authority in particular fades when a founder dies, so it must be "routinized" into traditional and legal forms.
Checkpoint

A country divides sovereignty constitutionally between a national government and regional governments that hold their own guaranteed powers. This describes which type of state, and which core country is an example?

On the exam

Keep the four core terms sharp: state (sovereign territory), nation (shared identity), regime (enduring rules/institutions), government (current officeholders). AP prompts frequently test whether you can tell a change of government (an election) from a change of regime (a revolution).

Checkpoint

Citizens obey the authority of an office because it was established through recognized laws and constitutional procedures, not because of the personality of the officeholder. Which type of legitimacy is this?

Tip

Map the core six by structure to memorize them: unitary = UK, China, Iran; federal = Russia, Mexico, Nigeria. Pairing each country with its structure early makes later institutional comparisons much faster.
