AP Human Geography Notes

Unitary vs. Federal States

  • Unitary State:
    • A single, identifiable nation of people spread over multiple states with a unitarian government.
    • Power is centralized at one level, typically the national level.
    • Examples: China, France.
  • Federal State:
    • Power is divided among different levels: national, state/territory, county, local, city.
    • Example: The United States, where power is distributed to prevent the national government from becoming too powerful.

Centrifugal and Centripetal Forces

  • Centrifugal Forces:
    • Forces that pull or force people apart.
    • Examples: political party affiliation, language, religion, ethnic identity, history.
    • These forces can cause conflict and division.
  • Centripetal Forces:
    • Forces that pull people together.
    • These can include the same traits that sometimes act as centrifugal forces (e.g., political party for those within it).

Balkanization and Devolution

  • Balkanization:
    • The process where an area breaks apart into independent states, often due to ethnic or cultural differences.
    • Named after the Balkans in Eastern Europe, where Yugoslavia broke apart into countries like Slovenia, Croatia, Bosnia and Herzegovina, Serbia, and Montenegro.
  • Devolution:
    • The transfer of power from a central national government to different levels in a hierarchy.
    • When a country devolves, the national government loses power, which is then shared throughout the country.
    • Devolution can sometimes lead to balkanization.

Choke Points and Shatter Belts

  • Choke Points:
    • Narrow strips of water connecting larger bodies of water that act like funnels for military, shipping, and trade traffic.
    • Examples: Panama Canal, Suez Canal, Strait of Hormuz, Sea of Azov.
    • The country controlling a choke point has significant power over military and trade movements.
  • Shatter Belts:
    • Countries located between two or more larger, competing powers, causing fragmentation and stress.
    • Example: Ukraine, caught between Russia and NATO/EU, with internal divisions between pro-Russian and pro-Ukrainian factions.
    • Shatter belts can experience conflict or balkanization due to external pressures.

Irredentism and Territoriality

  • Irredentism:
    • A country's belief that it should control a territory or area because it historically belonged to them.
    • Example: China's claim to the South China Sea based on historical control.
  • Territoriality:
    • A country's aggressive assertion and defense of its perceived space or territory.
    • Territoriality can be caused by irredentism.
    • Example: China building islands and sending military ships to the South China Sea to assert its claim and scare away other countries' boats.
