The Nile is the major north-flowing river in Africa. The River Nile flows through various countries in the northeastern part of Africa, finally opening up into the Mediterranean Sea. This river has been the lifeline for civilizations since the Stone Age.
Why it is special: 6,853 km long, the Nile is considered to be the longest river in the world. The Nile has two main tributaries, namely the White Nile (which is said to be the headwaters and the primary stream) and the Blue Nile (which is the source of the water and silt). This river has been the foundation for the growth of many civilizations, specifically in Egypt, so much so that historians through the ages have said that Egypt is the gift of the Nile.
