River Valley Civilizations: Egypt, Mesopotamia, Indus, China, and Mesoamerica

Major ancient civilizations arose along rivers:

• Egypt – Nile River: Predictable floods created fertile soil; enabled irrigation, transport, fishing.
• Mesopotamia (Iraq) – Tigris & Euphrates: Irrigation supported Sumerians, Babylonians, Assyrians; trade and communication hub.
• India – Indus River: Indus Valley Civilization; advanced irrigation, wheat/barley cultivation, trade links.
• China – Yellow River (Huang He): Fertile loess soil from floods; agriculture, transport, cultural exchange.
• Mesoamerica – Usumacinta, Motagua, San Juan Rivers: Maya and Aztec civilizations; water for drinking, irrigation, trade, rituals.
