Ethnic cleavages are divisions within a society based on ethnic identity that shape voting behavior, party systems, and political stability. In AP Comparative Government, key examples include China's Han majority versus Uighur and Tibetan minorities and Nigeria's regionally concentrated ethnic groups.
An ethnic cleavage is a line that divides a society based on ethnic identity. Think of a cleavage as a crack running through a country's population. When that crack follows ethnicity, people on each side may speak different languages, follow different traditions, and, most importantly for this course, vote differently, join different parties, and trust the government differently.
The CED (LEG-2.A.1) defines cleavages as internal divisions that structure societies, based on class, ethnicity, religion, or territory. The flagship ethnic example is China, where the majority Han ethnic group sits alongside at least 55 recognized ethnic minorities, including the Uighurs in the northwest and the Tibetans in the southwest. Nigeria is the other heavyweight example, with hundreds of ethnic groups (Hausa-Fulani, Yoruba, Igbo being the largest) concentrated in different regions. Russia's Chechens and Mexico's Amerindian populations also show up in this conversation. The key move is recognizing that an ethnic cleavage is a structural feature of a society, not automatically a war. What matters is how the state responds to it.
Ethnic cleavages live in Topic 3.8 (Political and Social Cleavages) in Unit 3: Political Culture and Participation, supporting two learning objectives. AP Comp Gov 3.8.A asks you to describe politically relevant social cleavages, and AP Comp Gov 3.8.B asks you to explain how those cleavages affect citizen relationships and political stability. That second LO is where the points are. Per LEG-2.B.1, cleavages shape voting behavior, party systems, and informal political networks, and per LEG-2.B.2, states respond to them in very different ways, ranging from brute repression to recognizing minorities, creating autonomous regions, or guaranteeing minority representation in government. Ethnic cleavages are also one of the best comparison tools in the whole course, because every one of the six course countries handles its divisions differently. That makes this term a go-to for comparative analysis questions.

Coinciding Cleavages (Unit 3)
Ethnic cleavages get dangerous when they stack on top of other divisions. In Nigeria, ethnicity, religion, and region all line up (a largely Muslim Hausa-Fulani north, a more Christian Igbo southeast), which reinforces the divide instead of cutting across it. Coinciding cleavages explain why some divided societies stay tense while others stay stable.
Separatist Movements (Units 1 and 3)
When an ethnic group is concentrated in one territory, an ethnic cleavage can become a sovereignty problem. Chechens in Russia are the classic case of a territorially concentrated ethnic minority producing a separatist challenge, which links cleavages back to Unit 1's challenges to state sovereignty.
Minority Rights (Unit 3)
State responses to ethnic cleavages sit on a spectrum the CED spells out, from repression to recognition. China created autonomous regions for groups like Tibetans and Uighurs on paper while tightly controlling them in practice. Whether a state protects or suppresses minority rights tells you a lot about its regime type.
Nationalism (Unit 3)
Governments often push a unifying national identity to paper over ethnic cleavages. China promotes a single Chinese national identity over its 55-plus minority identities. Nationalism can either glue a divided society together or, when it belongs to the majority group alone, deepen the cleavage.
Ethnic cleavages show up most often in comparative multiple-choice stems that make you contrast how the same kind of division plays out in different course countries. Practice questions ask things like why ethnic cleavages in Nigeria affect the party system differently than religious cleavages in Iran, how ethnic cleavages in Mexico affect stability differently than in Nigeria, and how China's government manages ethnic cleavages to maintain stability. Notice the pattern. You are never just defining the cleavage; you are explaining its consequence (voting behavior, party formation, instability) or the state's response (repression, autonomous regions, federalism). No released FRQ has used this exact phrase verbatim, but the Comparative Analysis FRQ is built for it, since cleavage management is one of the cleanest similarity-and-difference setups across the six course countries. Always pair the cleavage with a specific country example and a specific government response.
Both are social cleavages under Topic 3.8, but they divide along different lines. An ethnic cleavage is about identity and ancestry (Han vs. Uighur in China), while a religious cleavage is about faith (the Shi'a majority vs. Christians, Jews, and Zoroastrians in Iran). The exam loves this distinction because the two have different political effects. Nigeria's ethnic divisions are regionally concentrated and historically shaped its parties along ethnic lines, while Iran's religious cleavage defines who holds power in a theocracy. The trap is Nigeria itself, where ethnic and religious cleavages coincide, so be precise about which division you are describing.
An ethnic cleavage is a division in society based on ethnic identity, and the CED treats it as one of four main cleavage types alongside class, religion, and territory.
China's core ethnic cleavage is between the Han majority and at least 55 recognized minorities, including the Uighurs in the northwest and the Tibetans in the southwest.
Cleavages matter politically because they shape voting behavior, party systems, and informal networks, which is the heart of learning objective AP Comp Gov 3.8.B.
State responses to ethnic cleavages range from brute repression to recognizing minorities, creating autonomous regions, or guaranteeing minority representation in government.
Ethnic cleavages are most destabilizing when they coincide with religious or regional divisions, as in Nigeria, and less destabilizing when divisions cut across each other.
On the exam, never stop at naming the cleavage; explain its political consequence or the government's response to earn the point.
Ethnic cleavages are divisions within a society based on ethnic identity that affect politics, like voting patterns, party systems, and stability. They are covered in Topic 3.8 of Unit 3, with China's Han-versus-minority divide and Nigeria's ethnic regions as the main examples.
No. A cleavage is just a division, and its effect depends on whether it coincides with other cleavages and how the state responds. Governments can manage ethnic cleavages through recognition, autonomous regions, or minority representation, or inflame them through repression.
Ethnic cleavages divide people by identity and ancestry, while religious cleavages divide them by faith. The CED's go-to contrast is China's Han-versus-Uighur ethnic divide versus Iran's split between the Shi'a Muslim majority and Christians, Jews, and Zoroastrians. Nigeria has both, and they overlap.
Nigeria (Hausa-Fulani, Yoruba, and Igbo among hundreds of groups), China (Han majority versus at least 55 recognized minorities like Uighurs and Tibetans), Russia (Chechens and other minorities), and Mexico (Amerindian populations) are the strongest examples. The UK's divisions are more national and regional, like Scotland.
China combines formal recognition with tight control. It officially recognizes at least 55 ethnic minorities and has designated autonomous regions for groups like Tibetans and Uighurs, but in practice it restricts minority political activity to maintain stability. This makes China a classic exam example of the repression end of the state-response spectrum.
