Devolution is the transfer of power from a central government to regional or local governments within a unitary state, like the UK granting Scotland, Wales, and Northern Ireland their own parliaments after 1997 referenda. The central government keeps sovereignty and can legally take that power back.
Devolution is what happens when a central government hands decision-making power down to regional or local governments. The classic AP example is the United Kingdom, a unitary state that devolved power to Scotland, Wales, and Northern Ireland after the 1997 referenda. Scotland got its own parliament with authority over things like education and health, and Wales got a national assembly. Here's the catch that makes devolution different from federalism. In a devolved system, the central government still holds all the legal sovereignty. Westminster gave Scotland its parliament, and Westminster could (in theory) take it away. The regions govern at the pleasure of the center.
Why would a central government voluntarily give up power? Usually to manage territorial and ethnic cleavages. When Scots feel governed by a distant London government that doesn't represent them, devolution is a pressure-release valve. It gives regional populations a stake in the system without breaking up the country. The CED frames this directly in Topic 1.9. Devolution and delegation of power to regional governments is one of the ways states try to sustain legitimacy. It can also backfire, though. Giving Scotland a parliament gave Scottish nationalism an institutional home, which fed the 2014 independence referendum.
Devolution sits at the crossroads of three units. In Unit 1, it's central to Topic 1.7 (AP Comp Gov 1.7.A), where you compare federal and unitary systems. The CED notes that the degree of centralization can change over time in both system types, and devolution is exactly how a unitary state like the UK decentralizes without becoming federal. It also supports Topic 1.9 (AP Comp Gov 1.9.A), because devolving power to regions is one of the listed strategies governments use to maintain legitimacy. Then in Unit 3, devolution reappears in Topic 3.8 (AP Comp Gov 3.8.A and 3.8.B) as a state response to territorial and ethnic cleavages. The CED says state responses range from brute repression to creating autonomous regions, and devolution is the textbook example of the second option. If you can explain devolution well, you can answer questions across all three units.

Federal and Unitary Systems (Unit 1)
Devolution is the move that blurs the federal-unitary line. The UK is still officially unitary because Westminster retains sovereignty, but devolution makes it behave more like a federal state in practice. Compare that with China and Iran, unitary states that have kept power tightly centralized.
Sustaining Legitimacy (Unit 1)
The CED lists devolution as a tool for maintaining legitimacy. The logic is simple. When regional groups feel the system responds to them, they're more likely to accept the central government's authority instead of demanding independence.
Political and Social Cleavages (Unit 3)
Devolution is a state response to territorial cleavages. The Scottish-English divide in the UK is the prime example. Devolution channeled Scottish nationalism into a parliament instead of letting it fester, though it also gave the independence movement a platform.
Federalism (Unit 1)
Federalism is the concept students confuse with devolution most. In federal systems like Nigeria, Mexico, and Russia, regional power is constitutionally guaranteed. Devolved power is a gift from the center that can legally be revoked. Same decentralizing effect, very different legal foundation.
Devolution shows up most often in multiple-choice questions about the UK, usually testing whether you know why a unitary state would decentralize and what effect it has on legitimacy. Practice questions ask things like why UK devolution to Scotland, Wales, and Northern Ireland has generally enhanced central government legitimacy, and how the 1997 referenda functioned as direct democracy. Comparative stems also pair countries, like asking how devolution affects legitimacy differently in Russia versus Mexico (remember Russia has recentralized power away from regions, the opposite trend). On FRQs, devolution is a strong example for cleavage prompts. The 2018 SAQ asked about the political consequences of social and economic cleavages, and UK devolution is a ready-made example of a state responding to a territorial cleavage. Your job on the exam is to do three things with this term: define it precisely, attach it to a specific country example (UK is safest), and explain the causal link to legitimacy or cleavage management.
Both spread power across levels of government, but the source of regional power is different. In a federal system (Mexico, Nigeria, Russia), the constitution itself guarantees regional governments their powers, so the center can't unilaterally take them away. Devolution happens within a unitary system. The central government chooses to hand power down, and it legally keeps the right to claw it back. So the UK after devolution is still a unitary state, just a decentralized one. Quick test for the exam: ask where the regional power comes from. Constitution means federal. Grant from the center means devolution.
Devolution is the transfer of power from a central government to regional governments, and the AP's go-to example is the UK devolving power to Scotland, Wales, and Northern Ireland after the 1997 referenda.
Devolution is not federalism. In federalism regional power is constitutionally protected, while devolved power is granted by the center and can legally be revoked.
The UK remains a unitary state even after devolution because Westminster retains ultimate sovereignty.
The CED lists devolution as a way governments sustain legitimacy, because giving regions autonomy makes them more likely to accept the central government's authority.
Devolution is also a state response to territorial and ethnic cleavages, sitting on the accommodating end of a spectrum that runs from repression to autonomous regions.
Devolution can cut both ways. The Scottish Parliament boosted UK legitimacy but also gave Scottish nationalism the institutional base that produced the 2014 independence referendum.
Devolution is the transfer of power from a central government to regional or local governments within a country, most famously the UK granting Scotland, Wales, and Northern Ireland their own legislatures after 1997 referenda. The center keeps sovereignty, so the state stays unitary.
No. The UK is still a unitary state because Westminster retains ultimate sovereignty and could legally revoke the powers it devolved. Devolution decentralized the UK in practice, but federal status requires constitutional guarantees of regional power, which the UK doesn't have.
In federal systems like Mexico, Nigeria, and Russia, the constitution guarantees regional governments their powers. Devolution is a grant from the central government in a unitary state, and the center can take it back. The test is where regional power comes from, not how much power regions have.
To manage territorial cleavages and shore up legitimacy. Many Scots and Welsh felt unrepresented by the London government, so the 1997 referenda created regional legislatures that gave those populations a stake in the system instead of fueling separatism.
Not always. The CED frames devolution as a legitimacy-building tool, and in the UK it has generally worked. But it can also empower regional nationalism, as when the Scottish Parliament became the base for the 2014 independence referendum. Comparative MCQs may ask you to contrast outcomes, like Russia's recentralization versus other countries' decentralization.
