The Nile (Arabic: النيل‎, an-nīl, Ancient Egyptian iteru or Ḥ'pī, Coptic piaro or phiaro) is a major north-flowing river in North Africa, generally regarded as the longest river in the world. The northern section of the river flows almost entirely through desert, from Sudan into Egypt, a country whose civilization has depended on the river since ancient times. Most of the population and cities of Egypt lie along those parts of the Nile valley north of Aswan, and nearly all the cultural and historical sites of Ancient Egypt are found along riverbanks. The Nile ends in a large delta that empties into the Mediterranean Sea.
