The river that was the ancient cradle of civilization for the Egyptians is the Nile River. This river, one of the longest in the world, flows through northeastern Africa and has been crucial for human settlement in the region. Its annual floods deposited nutrient-rich silt on the surrounding land, enabling agriculture to thrive and supporting the development of one of history's most significant civilizations. The Nile was also essential for transportation and trade, further contributing to the prosperity of ancient Egypt and its cultural achievements.
