Introduction to Political Geography
Syllabus
Source: College Board AP Course and Exam Description
Political geography 政治地理学 studies how humans divide and control space. Its key units:
- A state 国家 (country) is an area with defined borders, a permanent population, a government, and sovereignty 主权 — full control over its own affairs.
- A nation 民族 is a group of people with a shared culture and identity; a nation-state 民族国家 is a state whose borders match one nation (Japan is close).
- A multinational state 多民族国家 contains several nations; a stateless nation 无国家民族 (like the Kurds) has no state of its own.
Worked example (a real AP exam question). "Define the concept of an independent state." (2025) A full-mark answer: "A sovereign country that governs itself and its own territory, is not controlled by any outside power, and is recognised by other states." The command word Define wants a short, precise meaning — one clear sentence is enough. You do not need examples or explanation here; save those for the "Describe" and "Explain" parts.

Territoriality 领域性 is the attempt by a person or group to control people and things by controlling an area. Power is expressed geographically through control of land, people, and resources.
- Colonialism and imperialism built empires by taking control of distant territory; neocolonialism 新殖民主义 is continued economic control after formal independence.
- Choke points 咽喉要道 (narrow straits like Suez or Malacca) and shatterbelts 破碎地带 (regions caught between competing powers) show how geography shapes political power.

A boundary 边界 is a line that marks the limit of a state's territory. Types by origin:
States take different shapes; each shape affects how easily the state can be governed
- Antecedent 先成边界 (drawn before dense settlement), subsequent 后成边界 (drawn as cultures develop), superimposed 叠加边界 (forced on by an outside power, ignoring local culture), and relic 残余边界 (no longer a border but still visible, like the Berlin Wall).
- Definition, delimitation, and demarcation are the steps of setting a boundary: agreeing wording, drawing it on a map, then marking it on the ground.
- At sea, the UN Convention on the Law of the Sea (UNCLOS) 联合国海洋法公约 sets each coastal state's territorial sea and an exclusive economic zone (EEZ) 专属经济区, defining rights to fishing and seabed resources.
- The shape of a state matters: compact states are easy to govern; elongated, fragmented, perforated, and prorupted shapes create governing challenges.

States organise power between the centre and the regions in two main ways:
A unitary state keeps power central; a federal state shares power with regional governments
- A unitary state 单一制国家 keeps most power in the central government (France). It works best in small or culturally uniform countries.
- A federal state 联邦制国家 shares power between the centre and regional governments (USA, India). It suits large or diverse countries.
- Gerrymandering 选区划分不公 is redrawing voting district boundaries to favour one group — a political use of geography.

Devolution 权力下放 is the transfer of power from a central government down to regional governments. It is driven by devolutionary factors: ethnic or religious differences, physical geography (islands, mountains), and economic inequality.
- Strong differences can lead to autonomy 自治 for a region, or even a movement for full independence.
- Sovereignty is also challenged from outside by supranational organisations 超国家组织 (the EU, UN), by globalisation, and by the internet, which crosses borders freely.

Two opposing forces act on every state:
- Centrifugal forces 离心力 pull a state apart — ethnic conflict, uneven development, and weak identity can lead to failed states 失败国家 and separatist movements.
- Centripetal forces 向心力 hold a state together — a shared language, national symbols, fair infrastructure, and a strong national identity (ethnonationalism 族裔民族主义 when tied to one ethnic group).
Governments strengthen centripetal forces (national holidays, a common language) to keep the state unified. Balancing these forces is the central task of political geography.
Centrifugal or centripetal force?
A centrifugal force pulls a state apart; a centripetal force holds it together.

Exam tips
- Keep state (territory + sovereignty), nation (a people), and nation-state clearly separate.
- Classify a boundary by history (antecedent / subsequent / superimposed / relict) and by stage (defined to administered).
- Name the boundary-dispute type: definitional, locational, operational, or allocational.
- Compare unitary and federal governance, and link the choice to managing diversity.
- Explain instability through centrifugal and centripetal forces and devolution; use neutral examples.
