The river that runs through Egypt is the Nile River. Spanning approximately 6,650 kilometers, it is one of the longest rivers in the world. The Nile has two main tributaries, the White Nile and the Blue Nile, and it flows through several countries before emptying into the Mediterranean Sea. Historically, the Nile has been crucial to the development of ancient Egyptian civilization, providing water, fertile soil, and transportation. The annual flooding of the Nile deposited nutrient-rich silt along its banks, allowing agriculture to flourish and supporting the growth of one of history's most iconic civilizations.
