Ancient EgyptPyramids, engineering, a 3,000-year state
Ancient GreeceDemocracy, philosophy, geometry

Each borrowed from and traded with its neighbors.

Why they rise and why they fall

  • Reliable food from farming
  • Strong institutions and laws
  • Trade and new technology

Fall

  • Divided leadership and debt

Remember

Civilizations last when food, institutions and trade stay strong, and fall when several stresses hit at once.
