The Nile is the longest river in the world with a total length of 6,650 km. But there is a debate also on this. The historic consensus of geographic authorities has been to regard the Amazon as the second longest river in the world, with the Nile being the longest. However, the Amazon has been measured by different geographers and they said that amazon is the Longest one with 6,800 kilometres. But since we prefer Nile as the Longest river so Let take more information of it only.

The Nile runs through the eleven countries of Sudan, South Sudan, Burundi, Rwanda, Democratic Republic of the Congo, Tanzania, Kenya, Ethiopia, Eritrea, Uganda and Egypt. Cairo, Thebes/Luxor, Khartoum, Gondokoro, Aswan, and Karnak are several major cities that are located along the edge of the Nile. Before stopped by dams the Nile would overflow every year leaving deposits of rich soil along the banks. The Nile ends in a large delta that empties into the Mediterranean Sea. The Nile is also known as the White Nile. It is a term also used in a limited sense to describe the section between Lake No and Khartoum. The White Nile starts in equatorial East Africa while the Blue Nile begins in Ethiopia. Both branches are on the western flanks of the East African Rift. The drainage basin of the Nile covers 3,254,555 square kilometers. This is about 10% of the area of Africa. Many factors including weather, diversions, evaporation and evapotranspiration, and groundwater flow affect the discharge at any given point along the mainstem as the Nile basin is complex. Lake Victoria is considered to be the source of the Nile sometimes but the lake has feeder rivers of considerable size. The Kagera River, which flows into Lake Victoria near the Tanzanian town of Bukoba, is the longest feeder.

The Latin Nilus and the Ancient Greek ?e???? is considered to be the source of The English name Nile and the Arabic names en-Nîl and an-Nîl. A Semitic Nahal is also a possible etymology meaning "river". The Ancient Egyptians called the river Ar or Aur which means "black" because the annual flood left black sediment along the river banks. Numerous animals Nile crocodiles, Nile monitors, frogs, mongooses, turtles, tortoises, hippopotamus, wildebeest, baboons, and over three hundred species of birds live in and around the river. The Aswan High Dam, Roseires Dam, Owen Falls Dam, and Sennar Dam are the major dams built on the nile river. The Egyptians used to thank Hapi for bringing fertility for the land when a flood came because according to them honoring a god was crucial and very important.
