The Nile is a major north-flowing river in northeastern Africa. It flows into the Mediterranean Sea. The Nile is the longest river in Africa. It has historically been considered the longest river in the world, though this has been contested by research suggesting that the Amazon River is slightly longer. Of the world's major rivers, the Nile is one of the smallest, as measured by annual flow in cubic metres of water. About 6,650 km (4,130 mi) long, its drainage basin covers eleven countries: the Democratic Republic of the Congo, Tanzania, Burundi, Rwanda, Uganda, Kenya, Ethiopia, Eritrea, South Sudan, Sudan, and Egypt. In particular, the Nile is the primary water source of Egypt, Sudan and South Sudan. The Nile is an important economic driver supporting agriculture and fishing.
Sudan, officially the Republic of the Sudan, is a country in Northeast Africa. It borders the Central African Republic to the southwest, Chad to the west, Libya to the northwest, Egypt to the north, the Red Sea to the east, Eritrea and Ethiopia to the southeast, and South Sudan to the south. Sudan has a population of 50 million people as of 2024 and occupies 1,886,068 square kilometres, making it Africa's third-largest country by area and the third-largest by area in the Arab League. It was the largest country by area in Africa and the Arab League until the secession of South Sudan in 2011; since then both titles have been held by Algeria. Sudan's capital and most populous city is Khartoum.
The history of Sudan refers to the territory that today makes up Republic of the Sudan and the state of South Sudan, which became independent in 2011. The territory of Sudan is geographically part of a larger African region, also known by the term "Sudan". The term is derived from Arabic: بلاد السودان bilād as-sūdān, or "land of the black people", and has sometimes been used more widely referring to the Sahel belt of West and Central Africa.
Sudan is located in Northeast Africa. It is bordered by Egypt to the north, the Red Sea to the northeast, Eritrea and Ethiopia to the east, South Sudan to the south, the Central African Republic to the southwest, Chad to the west and Libya to the northwest. Sudan is the third largest country in Africa, after Algeria and the Democratic Republic of the Congo. It was the largest country on the continent until South Sudan split off from it in 2011.
The Blue Nile is a river originating at Lake Tana in Ethiopia. It travels for approximately 1,450 km (900 mi) through Ethiopia and Sudan. Along with the White Nile, it is one of the two major tributaries of the Nile and supplies about 85.6% of the water to the Nile during the rainy season.
Equatoria is the southernmost region of South Sudan, along the upper reaches of the White Nile and the border between South Sudan and Uganda. Juba, the national capital and the largest city in South Sudan, is located in Equatoria. Originally a province of Anglo-Egyptian Sudan, it also contained most of northern parts of present-day Uganda, including Lake Albert and West Nile. It was an idealistic effort to create a model state in the interior of Africa that never consisted of more than a handful of adventurers and soldiers in isolated outposts.
Dongola, also known as Urdu or New Dongola, is the capital of Northern State in Sudan, on the banks of the Nile. It should not be confused with Old Dongola, a now deserted medieval city located 80 km upstream on the opposite bank.
The Funj Sultanate, also known as Funjistan, Sultanate of Sennar or Blue Sultanate, was a monarchy in what is now Sudan, northwestern Eritrea and western Ethiopia. Founded in 1504 by the Funj people, it quickly converted to Islam, although this conversion was only nominal. Until a more orthodox form of Islam took hold in the 18th century, the state remained an "African empire with a Muslim façade". It reached its peak in the late 17th century, but declined and eventually fell apart in the 18th and 19th centuries. In 1821, the last sultan, greatly reduced in power, surrendered to the Ottoman Egyptian invasion without a fight.
Anglo-Egyptian Sudan was a condominium of the United Kingdom and Egypt between 1899 and 1956, corresponding mostly to the territory of present-day South Sudan and Sudan. Legally, sovereignty and administration were shared between both Egypt and the United Kingdom, but in practice the structure of the condominium ensured effective British control over Sudan, with Egypt having limited local power and influence. In the meantime, Egypt itself fell under increasing British influence. Following the Egyptian Revolution of 1952, Egypt pushed for an end to the condominium, and the independence of Sudan. By agreement between Egypt and the United Kingdom in 1953, Sudan was granted independence as the Republic of the Sudan on 1 January 1956. In 2011, the south of Sudan itself became independent as the Republic of South Sudan.
Benishangul-Gumuz is a regional state in northwestern Ethiopia bordering Sudan. It was previously known as Region 6. The region's capital is Assosa. Following the adoption of the 1995 constitution, the region was created from the westernmost portion of the Gojjam province, and the northwestern portion of the Welega Province. The name of the region comes from two peoples – Berta and Gumuz.
Alodia, also known as Alwa, was a medieval kingdom in what is now central and southern Sudan. Its capital was the city of Soba, located near modern-day Khartoum at the confluence of the Blue and White Nile rivers.
Turco-Egyptian Sudan, also known as Turkish Sudan or Turkiyya, describes the rule of the Eyalet and later Khedivate of Egypt over what is now Sudan and South Sudan. It lasted from 1820, when Muhammad Ali Pasha started his conquest of Sudan, to the fall of Khartoum in 1885 to Muhammad Ahmad, the self-proclaimed Mahdi.
The Mahdist State, also known as Mahdist Sudan or the Sudanese Mahdiyya, was a state based on a religious and political movement launched in 1881 by Muhammad Ahmad bin Abdullah against the Khedivate of Egypt, which had ruled Sudan since 1821. After four years of struggle, the Mahdist rebels overthrew the Ottoman-Egyptian administration and established their own "Islamic and national" government with its capital in Omdurman. Thus, from 1885 the Mahdist government maintained sovereignty and control over the Sudanese territories until its existence was terminated by the Anglo-Egyptian forces in 1898.
The Mahdist War was a war between the Mahdist Sudanese, led by Muhammad Ahmad bin Abdullah, who had proclaimed himself the "Mahdi" of Islam, and the forces of the Khedivate of Egypt, initially, and later the forces of Britain. Eighteen years of war resulted in the creation of Anglo-Egyptian Sudan (1899–1956), a de jure condominium of the British Empire, and the Kingdom of Egypt, in which Britain had de facto control over Sudan. The Sudanese launched several unsuccessful invasions of their neighbours, expanding the scale of the conflict to include not only Britain and Egypt but also the Italian Empire, the Congo Free State and the Ethiopian Empire.
Nubia is the term commonly used by scholars to refer to the land located south of Ancient Egypt, from the city of Elephantine down to modern-day Khartoum. Nubia has been one of the earliest humanly inhabited lands in the world. Its history is tied to that of Egypt, from which it became independent in the 10th century BC. The rich gold deposits in Nubia made the latter the target of Ancient Egyptians, Greeks, Romans and later Arabs. Research on Nubia has allowed scholars to find several of its references.
The Khedivate of Egypt was an autonomous tributary state of the Ottoman Empire, established and ruled by the Muhammad Ali Dynasty following the defeat and expulsion of Napoleon Bonaparte's forces which brought an end to the short-lived French occupation of Lower Egypt. The Khedivate of Egypt had also expanded to control present-day Sudan, South Sudan, Eritrea, Djibouti, northwestern Somalia, northeastern Ethiopia, Lebanon, Jordan, Palestine, Syria, Greece, Cyprus, southern and central Turkey, in addition to parts from Libya, Chad, Central African Republic, Democratic Republic of Congo, and Uganda, as well as northwestern Saudi Arabia, parts of Yemen and the Kingdom of Hejaz.
The Hamaj Regency was a political order in modern-day central Sudan from 1762 to 1821. During this period the ruling family of the Funj Sultanate of Sennar continued to reign, while actual power was exercised by the regents.
The Turco-Egyptian conquest of Sudan was a major military and technical feat. Fewer than 10,000 men set off from Egypt, but, with some local assistance, they were able to penetrate 1,500 km up the Nile River to the frontiers of Ethiopia, giving Egypt an empire as large as Western Europe.
The Kingdom of Fazughli was a precolonial state in what is now southeastern Sudan and western Ethiopia. Oral traditions assert its establishment to refugees from the Nubian Kingdom of Alodia, after its capital Soba had fallen to Arabs or the Funj in c. 1500. Centered around the mountainous region of Fazughli on the Blue Nile and serving as a buffer between the Funj sultanate and the Ethiopian empire, the kingdom lasted until its incorporation into the Funj sultanate in 1685.
Equatoria was a Mudiriyah of the Khedivate of Egypt in the late 19th century. It was located in modern-day South Sudan, the Democratic Republic of the Congo, and Uganda. Equatoria, as an Egyptian province, was created on the 26th of May, 1871, following the formal annexation of Gondokoro by Egypt, which was organized by Samuel Baker. Throughout its early existence, the provincial administration in Gondokoro was plagued by instability, as conflict with slave traders and the native Bari tribes meant that the governor only controlled the areas around the capital and the forts. However, during its later existence, Equatoria experienced a “golden period”, where the province was self-sufficient, prosperous, and the Egyptians under Emin Pasha maintained positive relations with both the interlacustrine kingdoms, and the surrounding tribes. Ultimately however, the outbreak of the Mahdist War in the Sudan which severed communications with Khartoum and Cairo, led to the fall of Equatoria, as Mahdist offensives led by Karam Allāh Muḥammad Kurkusāwī surrounded the Egyptian forts, which forced Emin to withdraw south to Wadelai, until he finally abandoned the province in early 1889, following an expedition sent to relieve his forces.
