RELAY 3: RIVER
The Agricultural Revolution
Rivers enabled the agricultural revolution. Irrigation systems, flood management, and water storage transformed human civilization from nomadic hunter-gatherers to settled agricultural societies. The great civilizations of Egypt, Mesopotamia, India, and China all developed along rivers.
River infrastructure included irrigation canals, dams, water storage systems, and flood management structures. These systems required sophisticated engineering, centralized planning, and coordinated labor—the foundations of organized civilization.
Control of river systems became the basis of political power. Civilizations that mastered river infrastructure accumulated surplus food, enabling the development of cities, specialized labor, and complex societies.

HISTORICAL SIGNIFICANCE
Timeline: Approximately 10,000 to 5,000 years ago, with the development of major river civilizations.
Impact: Enabled the agricultural surplus that supported cities, writing systems, organized religion, and complex governance. River civilizations became the cradles of human civilization.
Legacy: Water infrastructure remains critical. From hydroelectric power to irrigation to urban water systems, river infrastructure continues to determine civilizational success.
