Burundi in the context of "Nile river"

The Nile (also known as the Nile River or River Nile) is an important river in Africa that flows northwards into the Mediterranean Sea. At roughly 6,650 km (4,130 mi) long, it is among the longest rivers in the world. Its drainage basin covers eleven countries: the Democratic Republic of the Congo, Tanzania, Burundi, Rwanda, Uganda, Kenya, Ethiopia, Eritrea, South Sudan, Sudan, and Egypt. It plays an important economic role in the economy of these nations, and it is the primary water source for South Sudan, Sudan and Egypt.

The Nile has two major tributaries: the White Nile and the Blue Nile. The White Nile, being the longer, is traditionally considered to be the headwaters, while the Blue Nile actually contributes 80% of the water and silt below the confluence of the two. The White Nile begins at Lake Victoria and flows through Uganda and South Sudan, while the Blue Nile begins at Lake Tana in Ethiopia and flows into Sudan from the southeast. The two rivers meet at the Sudanese capital of Khartoum.

Lake Tanganyika (/ˌtæŋɡənˈjiːkə, -ɡæn-/ TANG-gən-YEE-kə, -⁠gan-; Kirundi: Ikiyaga ca Tanganyika) is an African Great Lake. It is the world's second-largest freshwater lake by volume and the second deepest, in both cases after Lake Baikal in Siberia. It is the world's longest freshwater lake. It is also the 6th largest lake by area. The lake is shared among four countries—Tanzania, the Democratic Republic of the Congo (the DRC), Burundi, and Zambia—with Tanzania (46%) and the DRC (40%) possessing the majority of the lake. It drains via the Lukuga River into the Congo River system, which ultimately discharges at Banana, Democratic Republic of the Congo into the Atlantic Ocean.

The East African Community (EAC) is an intergovernmental organisation in East Africa. The EAC's membership consists of eight states: Democratic Republic of the Congo, the Federal Republic of Somalia, the Republics of Burundi, Kenya, Rwanda, South Sudan, Uganda, and Tanzania. William Ruto, the president of Kenya, is the current EAC chairman. The organisation was founded in 1967, collapsed in 1977, and was revived on 7 July 2000. The main objective of the EAC is to foster regional economic integration.

In 2008, after negotiations with the Southern African Development Community (SADC) and the Common Market for Eastern and Southern Africa (COMESA), the EAC agreed to an expanded free trade area including the member states of all three organisations. The EAC is an integral part of the African Economic Community.

The Common Market for Eastern and Southern Africa (COMESA) is a regional economic community in Africa with twenty-one member states stretching from Tunisia to Eswatini. COMESA was formed in December 1994, replacing a Preferential Trade Area which had existed since 1981. Nine of the member states formed a free trade area in 2000 (Djibouti, Egypt, Kenya, Madagascar, Malawi, Mauritius, Sudan, Zambia and Zimbabwe), with Rwanda and Burundi joining the FTA in 2004, the Comoros and Libya in 2006, Seychelles in 2009, Uganda in 2012 and Tunisia in 2018.

COMESA is one of the pillars of the African Economic Community.

The African Pygmies (or Congo Pygmies, variously also Central African foragers, African rainforest hunter-gatherers (RHG) or Forest People of Central Africa) are a group of ethnicities native to Central Africa, mostly the Congo Basin, traditionally subsisting on a forager and hunter-gatherer lifestyle. They are divided into three roughly geographic groups:

• The western Bambenga, or Mbenga (Cameroon, Gabon, Republic of the Congo, Central African Republic),
• the eastern Bambuti, or Mbuti, of the Congo basin (DRC)
• the central and southern Batwa, or Twa (Rwanda, Burundi, DRC, Tanzania, Uganda, Zambia, Angola and Namibia). The more widely scattered (and more variable in physiology and lifestyle) Southern Twa are also grouped under the term Pygmoid.

They are notable for, and named for, their short stature (described as "pygmyism" in anthropological literature). They are assumed to be descended from the original Middle Stone Age expansion of anatomically modern humans to Central Africa, albeit substantially affected by later migrations from West Africa, from their first appearance in the historical record in the 19th century limited to a comparatively small area within Central Africa, greatly decimated by the prehistoric Bantu expansion, and to the present time widely affected by enslavement at the hands of neighboring Bantu, Ubangian and Central Sudanic groups.

The Democratic Republic of the Congo (DRC), also known as the DR Congo, Congo-Kinshasa, or simply the Congo, or more infrequently Zaire (its official name from 1971 to 1997), is a country in Central Africa. By land area, it is the second-largest country in Africa and the 11th-largest in the world. With a population of around 112 million, the DR Congo is the fourth-most populous in Africa and the most populous nominally Francophone country in the world. French is the official and most widely spoken language, though there are over 200 indigenous languages. The national capital and largest city is Kinshasa, which is also the economic center. The country is bordered by the Republic of the Congo, the Cabinda exclave of Angola, and the South Atlantic Ocean to the west; the Central African Republic and South Sudan to the north; Uganda, Rwanda, Burundi, and Tanzania (across Lake Tanganyika) to the east; and Zambia and Angola to the south. Centered on the Congo Basin, most of the country's terrain is covered by dense rainforests and is crossed by many rivers, while the east and southeast are mountainous.

The territory of the Congo was first inhabited by Central African foragers around 90,000 years ago and was settled in the Bantu expansion about 2,000 to 3,000 years ago. In the west, the Kingdom of Kongo ruled around the mouth of the Congo River from the 14th to the 19th century. In the center and east, the empires of Mwene Muji, Luba, and Lunda ruled between the 15th and 19th centuries. These kingdoms were broken up by Europeans during the colonization of the Congo Basin. King Leopold II of Belgium acquired rights to the Congo territory in 1885 and called it the Congo Free State. In 1908, Leopold ceded the territory after international pressure in response to widespread atrocities, and it became a Belgian colony. Congo achieved independence from Belgium in 1960 and was immediately confronted by a series of secessionist movements, the assassination of Prime Minister Patrice Lumumba, and the seizure of power by Mobutu Sese Seko in 1965. Mobutu renamed the country Zaire in 1971 and imposed a personalist dictatorship.

Tanzania, officially the United Republic of Tanzania, is a country in East Africa within the African Great Lakes region. It is bordered by Uganda to the northwest; Kenya to the northeast; the Indian Ocean to the east; Mozambique and Malawi to the south; Zambia to the southwest; and Rwanda, Burundi, and the Democratic Republic of the Congo to the west. According to a 2024 estimate, Tanzania has a population of around 67.5 million, making it the most populous country located entirely south of the equator.

Many important hominid fossils have been found in Tanzania. In the Stone and Bronze Age, prehistoric migrations into Tanzania included Southern Cushitic speakers similar to modern day Iraqw people, who moved south from present-day Ethiopia; Eastern Cushitic people who moved into Tanzania from north of Lake Turkana about 2,000 and 4,000 years ago; and the Southern Nilotes, including the Datoog, who originated from the present-day South Sudan–Ethiopia border region between 2,900 and 2,400 years ago. These movements took place at about the same time as the settlement of the Mashariki Bantu from West Africa in the Lake Victoria and Lake Tanganyika areas. In the late 19th century, the mainland came under German rule as German East Africa. This was followed by British rule after World War I when it was governed as Tanganyika, with the Zanzibar Archipelago remaining a separate colonial jurisdiction. Following their gaining respective independence in 1961 and 1963, the two entities merged in 1964 to form the United Republic of Tanzania.

Rwanda, officially the Republic of Rwanda, is a landlocked country in East Africa. Known as the "Land of a Thousand Hills" for its high elevation and rolling terrain, its geography is dominated by mountains in the west and savanna in the southeast. The largest and most notable lakes are mainly in the western and northern regions of the country, and several volcanoes that form part of the Virunga volcanic chain are primarily in the northwest. The climate is considered tropical highland, with two rainy seasons and two dry seasons each year. Its capital and largest city is Kigali, located at the centre of the country, at 1,567 metres above sea level.

Rwanda lies a few degrees south of the Equator in the Great Rift Valley of East Africa, where the African Great Lakes and Southeast Africa converge. Going clockwise Rwanda is bordered by Uganda to the north, Tanzania to the east, Burundi to the south, and the Democratic Republic of the Congo to the west.
