The Nile River flows through Egypt and has supported civilizations there for over 5,000 years by providing fertile land and resources. The annual flooding of the Nile deposited rich silt that allowed for highly productive agriculture. This dependence on the Nile led the Greek historian Herodotus to call Egypt "the Gift of the Nile." Modern Egypt continues to rely on the Nile through the Aswan High Dam, which generates electricity and provides irrigation.
