The Nile River travels through 10 countries in Africa, including Eritrea, Kenya, Burundi, Uganda, Congo, Tanzania, Ethiopia, Sudan, Egypt and Rwanda. In total, the river spans approximately 4,132 miles.
As the world's longest river, the Nile River served as an important place in Ancient Egypt. Major cities like Cairo and Luxor were located along the river. In addition, the famous Rosetta stone was found along the Nile River in 1787 in the city of Rosetta. This stone was important to helping historians understand the hieroglyphics that were used in Ancient Egypt.
The Nile River continues to have significance in the 21st century. It is believed that 40 million people live in the region of the Nile Delta.
