In AP Comparative Government, a cleavage is an internal division that structures a society, based on class, ethnicity, religion, or territory, and shapes voting behavior, party systems, and political stability in the six course countries (LEG-2.A.1).
A cleavage is a deep, durable division inside a society that sorts people into groups with different identities and conflicting political interests. The CED names four bases for cleavages: class, ethnicity, religion, and territory (LEG-2.A.1). The word "durable" matters. A cleavage isn't a one-time disagreement over a policy; it's a fault line that keeps producing political conflict election after election.
Every course country has signature cleavages you should be able to name. China has ethnic and regional divisions, including the Han majority versus minorities like the Uighurs and Tibetans, plus the gap between fast-developing coastal provinces and the poorer interior. Iran has a religious cleavage between the Shi'a Muslim majority and minorities like Christians, Jews, and Zoroastrians. Nigeria layers ethnic, religious, AND regional cleavages on top of each other (north vs. south, Muslim vs. Christian, Hausa-Fulani vs. Yoruba vs. Igbo). The exam wants country-specific examples, not just the abstract definition.
Cleavage is the core concept of Topic 3.8 (Political and Social Cleavages) in Unit 3: Political Culture and Participation. It supports 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 they affect citizen-state relationships and political stability. The essential knowledge (LEG-2.B.1, LEG-2.B.2) connects cleavages to voting behavior, party systems, and state responses ranging from brute repression to autonomy arrangements and minority representation. That makes cleavage one of the highest-leverage terms in the course, because it links Unit 3's participation content to sovereignty challenges, party systems, and regime stability everywhere else.

Coinciding Cleavages (Unit 3)
Cleavages get dangerous when they stack. If religion, region, and ethnicity all divide the same two groups (like Nigeria's Muslim north and Christian south), the divisions reinforce each other and conflict escalates. Cross-cutting cleavages, where the lines slice through each other, tend to dilute conflict instead.
Voting Behavior (Unit 3)
Cleavages are the why behind voting patterns. LEG-2.B.1 says cleavages shape voting behavior and party systems, which is why Nigerian parties historically formed around ethnic and regional lines while Iran's religious cleavage plays out through vetting by the Guardian Council rather than competing parties.
Separatist Movements (Unit 1)
When a territorial or ethnic cleavage hardens, it can produce groups that challenge state sovereignty itself, like demands for autonomy in Tibet and Xinjiang or Chechen separatism in Russia. This is the bridge from Unit 3 divisions to Unit 1 sovereignty challenges.
State Repression (Unit 3)
LEG-2.B.2 lays out the menu of state responses to cleavages, from brute repression (China's surveillance and detention of Uighurs) to accommodation (recognized minority seats, autonomous regions). Being able to compare a repressive response and an accommodating response across two course countries is classic FRQ material.
Cleavage shows up across question types, and it's appeared verbatim on released exams. The 2018 SAQ stated that "social and economic cleavages often divide society and can have both positive and negative political consequences" and asked you to work with that idea. The 2023 argument essay listed cleavages as one of the course concepts you could use to argue whether populism increases or decreases stability. A 2017 country-context question tied oil and gas wealth to internal economic and political divisions. Multiple-choice stems test country specifics, like which cleavage emerged in Russia after the Soviet collapse, how China's coastal-interior development gap creates regional cleavages, or why Nigeria's ethnic cleavages shape its party system differently than Iran's religious ones. The move you have to make every time is the same. Name the cleavage, identify its basis (class, ethnicity, religion, or territory), and explain its political consequence for voting, parties, or stability. Naming a division without the consequence only gets you halfway.
A cleavage is any single deep division (one fault line). Coinciding (or reinforcing) cleavages describe how multiple fault lines line up on top of each other, so the same groups face off on ethnicity AND religion AND region. Nigeria is the go-to example of coinciding cleavages. The distinction matters because coinciding cleavages predict instability, while cross-cutting cleavages can actually moderate conflict.
A cleavage is an internal division that structures a society, and the CED limits the bases to class, ethnicity, religion, and territory (LEG-2.A.1).
Cleavages matter politically because they shape voting behavior, party systems, and informal political networks (LEG-2.B.1).
Know one signature cleavage per course country, like Han versus Uighur/Tibetan and coastal versus interior in China, Shi'a majority versus religious minorities in Iran, and overlapping ethnic-religious-regional divides in Nigeria.
State responses to cleavages range from brute repression to recognition of minorities, autonomous regions, and guaranteed government representation (LEG-2.B.2).
Coinciding cleavages reinforce each other and raise the risk of instability, while cross-cutting cleavages tend to soften conflict.
On FRQs, a strong cleavage answer always pairs the division with its political consequence, never the division alone.
A cleavage is a deep, durable division within a society based on class, ethnicity, religion, or territory that separates groups with conflicting interests (LEG-2.A.1). Examples include China's Han-Uighur ethnic divide and Iran's Shi'a majority versus religious minorities.
No. The 2018 SAQ explicitly framed cleavages as having both positive and negative consequences. Cross-cutting cleavages can moderate conflict, and accommodation (like minority representation or autonomous regions) can channel divisions peacefully. Coinciding cleavages are the destabilizing kind.
A cleavage is the underlying division; ethnic conflict is one possible outcome when an ethnic cleavage turns violent or politically explosive. A cleavage can exist for decades without open conflict if the state manages it through representation or autonomy.
The CED identifies class, ethnicity, religion, and territory as the bases for politically relevant cleavages (LEG-2.A.1). Many course countries have cleavages on multiple bases at once, like Nigeria's ethnic, religious, and regional divides.
Yes, multiple times. The 2018 SAQ asked directly about cleavages' positive and negative political consequences, and the 2023 argument essay listed cleavages as a course concept for arguing about populism and political stability.
