Where Are the World's Primary Cultural Hearths?

Cultural hearths are regions where civilization first emerged and from which cultural traits diffused. The three foundational Old World hearths:

1. Mesopotamia (Modern Iraq)

Tigris-Euphrates valley. Sumer, Akkad, Babylon. Innovations: cuneiform writing, wheel, irrigation, law codes (Hammurabi), urbanism.

2. Ancient Egypt (Nile Valley)

Nile floodplain. Hieroglyphs, monumental architecture (pyramids, temples), advanced medicine/math, centralized state.

3. Indus Valley (Pakistan / NW India)

Indus River. Harappa, Mohenjo-daro. Grid-planned cities, standardized weights, sophisticated drainage, undeciphered script.

Additional hearths: Yellow River (China), Mesoamerica (Olmec/Maya/Aztec), Andes (Chavín/Inca). Each independently generated agriculture, cities, writing, and statehood.
