Devolution in AP Human Geography

Devolution is the transfer of power from a state's central government to regional or subnational governments. It can stay mild, with regions like Catalonia or Scotland gaining their own legislatures, or it can go all the way to a state breaking apart, as the Soviet Union did in 1991.

This definition is part of Fiveable's AP Human Geography review, which also has guided practice questions.

Six forces that can push a state toward devolution

Devolution is the core of Topic 4.8, Defining Devolutionary Factors, in Unit 4: Political Geography. That topic asks you to define the forces that cause it, and the unit's bigger question is how a state's sovereignty gets pressured from inside its own borders. The course frames each factor as something that can lead to devolution, so treat them as possible causes.

  • Division of groups by physical geography: distance or barriers make one central government hard to sustain. East and West Pakistan were separated by Indian territory, and East Pakistan became Bangladesh in 1971.
  • Ethnic separatism: an ethnic group wants self-rule or its own state, like many Catalans in Spain or Québécois in Canada.
  • Ethnic cleansing: the forced removal of an ethnic group from an area, often through threats or violence, including killing. This happened as Yugoslavia broke apart in the 1990s.
  • Terrorism: violence aimed at political goals, like the Basque group ETA's campaign for Basque independence from Spain.
  • Economic and social problems: uneven wealth, religious divides, or unequal services. Wealthy Catalonia resents sending tax money to poorer regions, and Nigeria has a mostly Muslim north and a largely Christian south.
  • Irredentism: a state claims territory in another state where people share its ethnicity, like Russia's annexation of Crimea from Ukraine in 2014.

A strong answer names the specific factor doing the work instead of just saying a region "wants independence."

From regional parliaments to a state falling apart

Topic 4.9, Challenges to Sovereignty, treats devolution as a range of outcomes. At one end, a state hands powers to subnational units and stays intact. Spain's autonomous communities, Belgium's split between Dutch-speaking Flanders and French-speaking Wallonia, Canada's Quebec, and Nigeria's states all fit here.

At the other end, the state disintegrates. The Soviet Union broke into 15 independent states in 1991, and Sudan split when South Sudan became independent in 2011.

Governments often devolve power on purpose, betting that some autonomy will calm separatist demands before they turn into secession. Topic 4.9 also points out that better communication technology has made devolution easier, since regional movements can organize and spread their message faster.

Why the UK is still unitary with a Scottish Parliament

Topic 4.7 says unitary states tend to be centralized and top-down, while federal states spread power across more local centers. The UK is the standard example where devolution blurs that line. It's formally unitary, yet Scotland, Wales, and Northern Ireland have their own governments controlling things like education and health care.

The UK stays unitary because Parliament in London granted those powers and keeps final authority over them. In a federal state like the U.S., state powers come from the constitution itself. Spatially, devolution means services such as schooling and health policy can differ by region inside one unitary country, which a fully centralized system wouldn't produce.

Writing devolution into Question 1's lettered parts

Question 1, the No-stimulus question, covers political devolution, centrifugal and centripetal forces, and state organization, with no map or data to lean on. You'll need your own examples ready. Expect parts that ask you to define a devolutionary factor, explain how it weakens a state, or describe how a government might respond.

A top answer connects the pieces. Devolutionary factors are centrifugal forces (they pull a state apart). Granting autonomy can work as a centripetal move if it keeps a region inside the state. Name a real place and a specific factor, then explain the effect on sovereignty or spatial organization.

In multiple choice, devolution may appear in a scenario or map involving a multinational state and an ethnic region, where you'd identify the cause or predict the outcome. Devolution can also show up in Questions 2 and 3 when a map or data set involves regional identity or separatism.

Devolution versus secession: the map test

Scotland gaining a parliament in 1999 often gets mislabeled as Scotland becoming independent, which treats every devolution case as secession. Ask whether a new sovereign state appeared on the map. Scotland's case is devolution, since Scotland is still part of the UK. South Sudan in 2011 is secession, the far end of the range, where the old state lost territory to a new one.

A second mix-up is assuming devolution makes a country federal. Devolved powers can exist inside a unitary state, as the UK shows.
