The Nile is the longest river in Africa and, according to the most frequently quoted data, is 6,650 kilometers long. Its outlet to the Mediterranean Sea in the form of a wide delta is located in Egypt (which it is called “the pearl”). On the other hand, some people consider the huge lake of Victoria as its source, which is nevertheless fed by large rivers such as the Kagera – sometimes they are included in the Nile basin. For this reason, the length of the Nile is measured differently depending on which point is considered its source. The reported data ranges from 5,499 to 7,088 km. Depending on which number we take, the Nile should be considered the longest river in the world or the second longest – it is fighting for this title with the Amazon in South America, the sources of which are also quite difficult to establish unequivocally.
