What this topic is asking
Topic 4.7 is about how power is organized inside a state. The College Board wants you to explain the difference between a unitary state and a federal state, and to analyze how each organizes power between the central government and the regions, and what that means for governing diversity, representation, and stability. The connecting idea is devolution (Topic 4.2): moving power outward from the center. The skill is to link the form of governance to how well a state handles its internal differences.
Unitary states
The first form concentrates power.
The risk of a unitary state is that a diverse population may feel unrepresented, since distant regions and minority nations have little control over their own affairs, which can fuel separatism.
Federal states
The second form shares power.
Federalism is a common tool for governing diversity: by giving nations within a multinational state (Topic 4.1) some autonomy, a federal arrangement can hold a varied country together.
Devolution and the spectrum of power
The two forms are ends of a spectrum, linked by devolution.
- Devolution is the transfer of power from a central government to regional or local authorities. A unitary state that devolves substantial power (for example, creating regional parliaments) moves toward a more federal arrangement.
- The choice and balance of governance affects stability: too much central control can alienate regions (a centrifugal force, Topic 4.9), while too much regional autonomy can weaken the state or, taken to the extreme, lead toward fragmentation.
These ideas connect directly to Topic 4.9 (centrifugal and centripetal forces) and Topic 4.8 (challenges to sovereignty), where the consequences of the power balance play out.
Why this matters for the exam
Forms of governance connect the political units of Topic 4.1 to the internal boundaries of Topic 4.6 and the cohesion forces of Topic 4.9. FRQs ask you to define a federal state, give an advantage of federalism for a diverse country, or link devolution to the unitary-federal spectrum, so practice matching a form of governance to how well it manages a country's diversity and stability.
Try this
Q1. Identify whether a state with a strong central government and weak regional units is unitary or federal. [Recall]
- Cue. Unitary; power is concentrated in the central government, unlike a federal state, which divides power with strong, often constitutionally protected regional units.
Q2. Explain one advantage of a federal system for governing a large, diverse country. [Short explanation]
- Cue. Regional governments can tailor policy to local needs and distinct ethnic or cultural groups gain a degree of self-rule, which helps govern diversity and can reduce separatist pressure.
Exam-style practice questions
Practice questions written in the style of College Board exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
AP 2018 (style)1 marksA state in which most political power is concentrated in a strong central government, with little authority given to regional units, is best described as: (A) a federal state. (B) a unitary state. (C) a confederation. (D) a multinational state.Show worked answer →
A stimulus-style multiple choice item. The correct answer is (B).
A unitary state concentrates power in a central government, with little authority delegated to regions. A federal state (A) divides power between a central government and regional units that hold significant authority; a confederation (C) is a loose union of largely independent units; a multinational state (D) is defined by containing several nations, not by how power is distributed.
The exam reward is matching strong central control with weak regions to the unitary form.
AP 2021 (style)3 marksStates organize power differently. (A) Define a federal state. (B) Explain ONE advantage of a federal system for governing a large or diverse country. (C) Explain how devolution relates to the unitary-federal distinction.Show worked answer →
A 3-point define-explain FRQ.
(A) Define (1 point): a federal state divides political power between a central government and regional units (states or provinces) that hold significant, often constitutionally protected, authority.
(B) Explain (1 point): federalism lets regional governments tailor policy to local needs and gives distinct ethnic or cultural groups a degree of self-rule, which helps govern large or diverse countries and can reduce separatist pressure.
(C) Explain (1 point): devolution is the transfer of power from a central (often unitary) government to regional authorities, moving a state in a more federal direction without necessarily becoming fully federal.
Markers reward an accurate definition, a real advantage of federalism, and a correct link between devolution and the unitary-federal spectrum.
