Blue Nile, also known as Abbay is a river originating at Lake Tana in Ethiopia. It is the major tributary of the Nile Basin Watershed and is also referred to as the “Blue Nile” once it is in the territory of Sudan. With the White Nile, it is one of the two major tributaries of the Nile.
Cairo, Egypt’s sprawling capital, is set on the Nile River. At its heart is Tahrir Square and the vast Egyptian Museum, a trove of antiquities including royal mummies and gilded King Tutankhamun artifacts.
Egypt, a country linking northeast Africa with the Middle East, dates to the time of the pharaohs. Millennia-old monuments sit along the fertile Nile River Valley, including Giza’s colossal Pyramids and Great Sphinx as well as Luxor’s hieroglyph-lined Karnak Temple and Valley of the Kings tombs.
The capital, Cairo, is home to Ottoman landmarks like Muhammad Ali Mosque and the Egyptian Museum, a trove of antiquities.
Ethiopia, in the Horn of Africa, is a rugged, landlocked country split by the Great Rift Valley. With archaeological finds dating back more than 3 million years, it’s a place of ancient culture. Among its important sites are Lalibela with its rock-cut Christian churches from the 12th–13th centuries. Aksum is the ruins of an ancient city with obelisks, tombs, castles and Our Lady Mary of Zion church.
Khartoum or Khartum is the capital of Sudan. With a population of 5,274,321, its metropolitan area is the largest in Sudan. Khartoum is located at the confluence of the White Nile, flowing north from Lake Victoria, and the Blue Nile, flowing west from Lake Tana in Ethiopia.
The Nile is a major north-flowing river in northeastern Africa, and is the longest river in Africa. The Nile is about 6,650 km (4,130 mi) long and its drainage basin covers eleven countries: Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Republic of the Sudan, and Egypt. In particular, the Nile is the primary water source of Egypt and Sudan.
The Nile has two major tributaries – the White Nile and the Blue Nile. The White Nile is considered to be the headwaters and primary stream of the Nile itself. The Blue Nile, however, is the source of most of the water, containing 80% of the water and silt. The White Nile is longer and rises in the Great Lakes region of central Africa, with the most distant source still undetermined but located in either Rwanda or Burundi. It flows north through Tanzania, Lake Victoria, Uganda and South Sudan. The Blue Nile begins at Lake Tana in Ethiopia and flows into Sudan from the southeast. The two rivers meet just north of the Sudanese capital of Khartoum.
The northern section of the river flows north almost entirely through the Sudanese desert to Egypt, then ends in a large delta and flows into the Mediterranean Sea. Egyptian civilization and Sudanese kingdoms have 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 river banks.
