Wanderlust World Wanderlust World The cradles of civilization arose along four great river systems that provided water, fertile silt, transportation, and ecological richness:
| Civilization | River(s) | Modern Location |
|---|---|---|
| Mesopotamia (Sumer, Akkad, Babylon, Assyria) | Tigris & Euphrates | Iraq, Syria, Turkey |
| Ancient Egypt | Nile | Egypt, Sudan |
| Indus Valley (Harappan) | Indus | Pakistan, NW India |
| Ancient China (Shang, Zhou) | Yellow River (Huang He) | China |
These "river hearths" share: annual flooding depositing nutrient-rich silt, enabling surplus agriculture; centralized irrigation management; and riverine trade networks that fostered cities, writing, and state formation.
