Learning Objectives
By the end of this lesson, students will be able to (per CED LO PSO-4.B):
- Identify the three CED-named foundational concepts that shape contemporary political geography: sovereignty, nation-states, and self-determination (per EK PSO-4.B.1).
- Identify the four CED-named historical processes that influenced contemporary political boundaries: colonialism, imperialism, independence movements, and devolution along national lines (per EK PSO-4.B.2).
- Distinguish colonialism (settlement and direct administration) from imperialism (broader political-economic domination, sometimes without settlement).
- Identify a contemporary case where self-determination claims conflict with state sovereignty and explain the tension.
- Apply Skill 3.E: explain what a world political map implies about colonial-era boundary creation.
Key Concepts
Per CED EK PSO-4.B.1, "the concepts of sovereignty, nation-states, and self-determination shape the contemporary world." Per CED EK PSO-4.B.2, "colonialism, imperialism, independence movements, and devolution along national lines have influenced contemporary political boundaries." This is two EKs covering seven distinct political-process terms — one of the densest content blocks in Unit 4.
The Westphalian state system
Modern sovereignty is the organizing principle of the international system. The Peace of Westphalia (1648) ended the Thirty Years' War in Europe and established the principle that states have supreme authority within their own territory and are equal as legal entities, regardless of size. The roughly 195 sovereign states of today's world political map are the heirs of this Westphalian system.
Sovereignty, nation-states, self-determination
The three foundational concepts of EK PSO-4.B.1 work together. Sovereignty is the state's right to govern itself. Nation-states (covered in Topic 4.1) are the ideal alignment of one nation and one sovereign state. Self-determination, codified in the UN Charter (1945), is the right of nations to choose their own political status. The tension is built in: self-determination claims (Catalonia, Kurdistan, Quebec, Tibet) often conflict with the existing sovereignty of established states.
Four historical forces (EK PSO-4.B.2)
EK PSO-4.B.2 names four specific forces that shaped today's borders. Colonialism involved settlement and direct administration of conquered territory; the colonial era (~1500-1960) reshaped almost all of Africa, Asia, and the Americas. Imperialism is broader political-economic domination, sometimes without large-scale settlement (British in India). Independence movements rolled back colonial control after WWII (the rapid decolonization of Africa and Asia in the 1950s-60s). Devolution along national lines further reshaped borders after the Cold War (Yugoslavia, Soviet Union breakup, Czech-Slovak split).
The Six CED-Named Processes
Per CED EKs PSO-4.B.1 and B.2. Memorize all six and at least one example of each.
Sovereignty
A state's right to govern its own territory and population without external interference. Foundational principle of the modern international system.
Nation-States
Sovereign states whose boundaries match those of one nation. Built around shared identity, language, religion, history.
Self-Determination
The principle that nations have the right to choose their own political status. Often in tension with existing state sovereignty.
Colonialism
Settlement and direct administration of conquered territory by an external power. Often imposed boundaries without regard to existing ethnic patterns.
Imperialism
Political and economic domination of one society by another, with or without settlement. Broader than colonialism.
Independence Movements
Organized movements by colonized peoples to gain sovereignty. Reshaped Asia and Africa across two decades after WWII.
Devolution Along National Lines
Transfer of power from central to subnational units organized around national identity. Sometimes leads to full state breakup.
Country Case Studies
Four cases that show the political processes producing today's map.

Nigeria · Colonial Boundaries Today
Nigeria's borders were drawn by Britain in the late 19th and early 20th centuries, with no regard for existing ethnic, linguistic, or religious patterns. The colonial-era boundary lumped together the Hausa-Fulani Muslim north, the Yoruba west, and the Igbo east, plus ~250 other ethnic groups. Internal political tensions trace directly to this colonial geography.

India · Independence and Partition
Indian independence from British imperialism (1947) is the textbook decolonization case. The partition into Hindu-majority India and Muslim-majority Pakistan followed self-determination logic but produced one of the largest forced migrations in history (~15M displaced) and ongoing border conflict in Kashmir. Decolonization rarely produces clean political geography.

Yugoslavia · Devolution Along National Lines
The breakup of socialist Yugoslavia (1991-2008) is the textbook devolution-along-national-lines case. Slovenia, Croatia, Bosnia, Macedonia, Montenegro, Kosovo, and Serbia emerged as separate states, mostly along ethnic and religious lines. The wars that accompanied the breakup show how violent devolution can be.
Country page →
United Kingdom · Asymmetric Devolution
Since the late 1990s, the UK has devolved powers to Scotland (full parliament), Wales (assembly with growing powers), and Northern Ireland (power-sharing assembly). The 2014 Scottish independence referendum (~55% No) and ongoing pressure show that devolution is not necessarily a one-time settlement — it can be a continuing process.
Country page →Discussion Questions
- Sovereignty has been the organizing principle of the international system since 1648. Identify two contemporary developments (climate change, the internet, supranational organizations) that challenge sovereignty as a principle. Is the Westphalian system breaking down or evolving?
- Self-determination and state sovereignty often conflict (Catalonia within Spain, Kurdistan within Turkey/Iraq, Tibet within China, Quebec within Canada). How do international law and geography weigh these competing claims? Is there a consistent rule, or do outcomes depend on power?
- Per EK PSO-4.B.2, colonialism shaped contemporary political boundaries. Most African and Middle Eastern borders were drawn by Europeans without regard to existing ethnic patterns. What political consequences are still visible today? What does this say about the durability of imposed boundaries?
- Distinguish colonialism from imperialism. The British Empire in India was heavily imperial but had relatively few British settlers. The British Empire in Australia was both colonial and imperial. Why does the distinction matter for understanding contemporary political geography?
- Devolution along national lines can be peaceful (Czech-Slovak split, 1993; Scottish referendum, 2014) or violent (Yugoslavia, 1991-2008). What conditions tend to produce peaceful devolution? What conditions produce violent breakup?
Classroom Activities
Decolonization Timeline
Pairs build a timeline showing the major waves of decolonization: 1947 (India, Pakistan), 1957 (Ghana — first Sub-Saharan African colony to independence), 1960 (the "Year of Africa," 17 new states), 1990 (Namibia), and 2002 (Timor-Leste). For each, they note the colonial power, the year, and one major boundary issue that resulted.
Sovereignty vs Self-Determination Debate
Class is divided into two sides: one defends established state sovereignty as inviolable; the other defends national self-determination. Each side picks two real cases (Catalonia, Kurdistan, Kosovo, Crimea) and presents 5-minute arguments. Cross-examination follows. Goal: understand the tension built into modern political geography.

AP Practice Questions
- (A) Colonialism, imperialism, and trade.
- (B) Federalism, devolution, and supranationalism.
- (C) Sovereignty, nation-states, and self-determination.
- (D) Boundaries, territories, and capitals.
- (E) Democracy, autocracy, and theocracy.
Correct: (C). EK PSO-4.B.1 names exactly these three. (A) is from EK PSO-4.B.2 (colonialism + imperialism are in there but trade is not).
Scoring: 2 points for sovereignty + self-determination definitions with explanation of conflict; 1 point for naming all four CED processes (colonialism, imperialism, independence movements, devolution); 2 points for one country case with specific historical example (Nigeria's colonial boundaries; India's 1947 partition; Yugoslavia's 1990s breakup); 2 points for one self-determination/sovereignty conflict case with explanation (Catalonia 2017 referendum vs Spanish constitutional sovereignty; Kurdish nation across 4 states vs each state's sovereignty).
