Western Dominance and Geography

Sep 22, 2025

Overview

This lecture explores why the West has historically dominated global power, analyzes long-term trends between East and West, and emphasizes geography as the key driver shaping human history, social development, and the future.

Competing Theories of Western Dominance

  • Two main theories: long-term lock-in (West's dominance set by ancient Greece) vs. short-term accident (Europe pulled ahead only recently).
  • Recent economic booms in East Asia challenge the lock-in theory.
  • Debates often lack clear definitions and quantitative measures.

Social Development and Measurement

  • "Social development" defined as a society’s ability to get things done: technology, organization, war-making, and information control.
  • Developed a Social Development Index using: energy capture, largest city size (organization), war-making capacity, and information technology.
  • Compared East and West from the end of the last Ice Age (ca. 14,000 B.C.) to present.

Patterns in Social Development

  • Western social development led most of the time, except A.D. 550–1750, when the East was ahead.
  • Major rises, stagnations, and collapses occurred, not a smooth upward trend.
  • Both regions’ developments shaped by changes in geography and technology.

Geography as the Main Driver

  • Geography determines where agriculture and complex societies begin (“lucky latitudes”).
  • Social development can change what geography "means" (e.g., rivers, seas, steppe routes).
  • Innovations in ships and guns enabled Western Europe to colonize the New World due to geographic proximity.

Key Historical Turning Points

  • Mediterranean and Atlantic trade transformed Western economies.
  • Scientific Revolution and Enlightenment in Europe were driven by geography-induced questions.
  • Industrial Revolution began in Britain due to geography and economic pressures.

Future Trends and Predictions

  • Social Development Index projects Eastern development surpassing the West by 2103 if trends continue.
  • Next century could see more change than all previous history combined.
  • Two possible futures: human transformation or large-scale disaster.

Risks and Optimism

  • Historical collapses tied to five “horsemen”: mass migration, epidemics, state collapse, famine, climate change.
  • Modern era faces the same risks, now with nuclear weapons.
  • Despite risks, humanity has greatly reduced violence and learned to manage large-scale conflict.

Key Terms & Definitions

  • Long-term lock-in theory — claims Western dominance started in ancient times and is permanent.
  • Short-term accident theory — claims Western dominance is a recent, temporary development.
  • Social Development Index — a quantitative measure of a society's technological, organizational, military, and informational capacity.
  • Lucky latitudes — regions suited for early agriculture due to geography.
  • Horsemen of the Apocalypse — symbolic for migration, epidemics, state collapse, famine, and climate change as causes of societal collapse.

Action Items / Next Steps

  • Read “Why the West Rules—For Now” for detailed methodology and further analysis.
  • Reflect on how geography shapes social and technological possibilities.
  • Consider implications of shifting global power and rapid technological change.
