What major river flows through the capital cities of both Egypt and Sudan?

The Nile River is the major river that flows through the capital cities of both Egypt, which is Cairo, and Sudan, which is Khartoum. It is the longest river in the world, stretching over 6,650 kilometers (4,130 miles) and flows northward through northeastern Africa, eventually emptying into the Mediterranean Sea.

In the case of Egypt, the Nile has historically been vital for agriculture, settlement, and trade, providing water in an otherwise arid region. Cairo, situated near the Nile delta, has developed around this crucial water source for millennia.

In Sudan, Khartoum is positioned at the confluence of the Blue Nile and White Nile rivers, making it a significant location for the country's culture and commerce as well. The river's role as a lifeblood for both cities showcases its importance in the history, economy, and daily life of the region.

The other rivers listed do not flow through either of these cities or countries. The Amazon River is primarily located in South America, the Yangtze River is in China, and the Ganges is in India, each serving crucial roles in their respective regions but lacking connection to the capitals of Egypt and Sudan.
