Unit 4.3 — Unitary and Federal Governance, and Devolution

Having a defined territory and a recognized boundary is only part of what makes a state function. States also have to decide how power is distributed internally — whether decisions get made in one central capital or spread out across regional governments, and how much authority those regional governments are allowed to exercise on their own. This lesson looks at the two dominant models of internal governance, unitary and federal, and at devolution, the process by which a state's central government voluntarily hands power down to regional or local units — sometimes as a release valve for the exact kinds of national and cultural tensions introduced in the first lesson of this unit.

Unitary states: power concentrated at the center

In a unitary state, most political power is concentrated in a single national government, and any regional or local governments that exist derive their authority from — and can have it revoked by — that central government. Regional administrative divisions in a unitary state (departments, prefectures, provinces) generally exist to implement national policy locally rather than to set independent policy of their own. France is the classic unitary example: its ninety-six metropolitan departments, along with its overseas territories, are administrative units of a single national government headquartered in Paris, and while France has experimented with limited regional decentralization since the 1980s, ultimate authority remains centralized. Japan and Egypt are also commonly cited unitary states, each governed by a strong national government with subordinate regional administration.

Unitary systems are common in states with a relatively homogeneous national population — where the "nation" and the "state" line up closely, as discussed in the first lesson of this unit, there is less internal pressure for regional governments to hold independent power, because most citizens already share a national identity centered on the capital. Unitary government is also efficient for coordinated national policy: a single government can enact and enforce a law uniformly across the whole territory without negotiating with semi-autonomous regional governments first.

Federal states: power divided by constitution

In a federal state, political power is constitutionally divided between a national government and a set of regional governments (states, provinces, Länder, or similar units), each of which holds meaningful authority in its own right that the central government cannot simply revoke. The United States is the most familiar example to American students: the Constitution grants specific enumerated powers to the federal government while reserving all other powers to the fifty states under the Tenth Amendment, producing genuine, constitutionally protected variation in law from one state to another — differing drinking ages, differing education standards, differing criminal codes.

Federal systems tend to emerge in states that are large in territory, contain significant regional or ethnic diversity, or were formed by the voluntary union of previously separate political units. Germany's postwar federal constitution divided the country into sixteen Länder partly as a deliberate reaction against the extreme centralization of the Nazi period. Nigeria, home to more than 250 distinct ethnic groups, adopted a federal structure with thirty-six states specifically to give its major regional and ethnic populations — Hausa-Fulani in the north, Yoruba in the southwest, Igbo in the southeast, among many others — a degree of self-governance within a single sovereign country. India's federal system similarly accommodates enormous linguistic and religious diversity across twenty-eight states and eight union territories, several of which were deliberately redrawn along linguistic lines in the 1950s and 1960s specifically to reduce internal tension. Brazil, Canada, Australia, and Mexico are other major federal states.

Devolution: power flowing outward from the center

Devolution is the process by which a central government grants increased political power — legislative authority, budgetary control, or cultural autonomy — to regional or local governments, without those regions becoming fully independent sovereign states. Devolution is best understood as a spectrum rather than a single event: a government can devolve a small amount of administrative authority, or it can devolve so much power that the remaining central government looks almost federal in practice, even in a country that started out constitutionally unitary.

The United Kingdom is the single most-cited devolution case in AP Human Geography. The UK is historically and constitutionally a unitary state — Parliament in Westminster is formally supreme and can, in principle, revoke any devolved power it has granted. But starting in 1997–1999, the UK devolved substantial law-making power to a new Scottish Parliament in Edinburgh, a Welsh Assembly (now the Senedd) in Cardiff, and a Northern Ireland Assembly in Belfast, each with authority over areas like education, health policy, and (for Scotland) some tax-setting power. Devolution in the UK was, in large part, a direct political response to long-standing Scottish and Welsh national identity — recall from the first lesson in this unit that a multinational state contains more than one nation, and devolution is one common strategy such a state uses to manage the tension that arrangement can produce, short of full independence. A 2014 referendum on full Scottish independence from the United Kingdom was defeated, 55% to 45%, but the vote itself demonstrates how devolution can coexist with, rather than eliminate, ongoing pressure for further autonomy or even secession.

Spain offers a comparable case: its 1978 constitution, adopted after the end of Francisco Franco's centralized dictatorship, created seventeen "autonomous communities," several of which — most prominently Catalonia and the Basque Country, each with its own distinct regional language and strong separate national identity — hold significant devolved authority over education, policing, and cultural policy. Canada devolved substantial autonomy to Quebec, whose francophone majority and distinct legal tradition (rooted in French rather than English common law) led to decades of negotiation over Quebec's status within the Canadian federation, including two independence referendums, in 1980 and 1995, both of which failed, the second by a margin of less than one percentage point.

Devolution does not always stop short of full separation. Belgium moved so far along the devolution spectrum — dividing power between Dutch-speaking Flanders, French-speaking Wallonia, and the Brussels-Capital Region through a series of constitutional reforms beginning in 1970 — that it formally became a federal state in 1993, an unusually clear example of a unitary state evolving all the way into a federal one through incremental devolution. And occasionally devolution's logical endpoint is reached: in 1993, Czechoslovakia peacefully split into two fully independent sovereign states, the Czech Republic and Slovakia, in what is often called the "Velvet Divorce" — a negotiated, non-violent dissolution that stands in sharp contrast to many other state breakups in modern history.

Why this matters for the exam

Exam questions on this topic usually ask you to identify whether a described government is unitary or federal, to explain why a specific state adopted one system over the other (look for clues about ethnic/national diversity, territorial size, or historical formation), or to trace a devolution case and explain what underlying national or cultural tension it was designed to manage. The strongest free-response answers connect devolution back to the state/nation vocabulary from earlier in this unit — a devolution movement is almost always a multinational state's institutional response to a nation within its borders pressing for greater self-determination. Keep the UK, Spain, and Canada cases specifically in mind; they appear across both multiple-choice and free-response prompts more often than any other devolution examples.
