Within the Malawi haplochromines there are two main groups, the haps and the mbuna . The haps (they were formerly included in Haplochromis ) can be further subdivided into three subgroups: The relatively large, often more than 20 cm (8 in) long, and aggressive piscivores that roam various habitats in pursuit of prey,
1464-700: A former Italian colony, gained independence. In 1956, Tunisia and Morocco won their independence from France. Ghana followed suit the next year (March 1957), becoming the first of the sub-Saharan colonies to be granted independence. Over the next decade, waves of decolonization took place across the continent, culminating in the 1960 Year of Africa and the establishment of the Organisation of African Unity in 1963. Portugal's overseas presence in sub-Saharan Africa (most notably in Angola , Cape Verde, Mozambique , Guinea-Bissau , and São Tomé and Príncipe) lasted from

It is probable that Wagadu's dominance on trade allowed for the gradual consolidation of many polities into a confederated state , whose composites stood in varying relations to the core, from fully administered to nominal tribute-paying parity. Based on large tumuli scattered across West Africa dating to this period, it has been stipulated that relative to Wagadu, there were further simultaneous and preceding kingdoms that have unfortunately been lost to time. At
2928-570: A native Libyan tribe, an ancestor of modern Berbers ; see Terence for discussion. The name had usually been connected with the Phoenician word ʿafar meaning "dust", but a 1981 hypothesis has asserted that it stems from the Berber word ifri (plural ifran ) meaning "cave", in reference to cave dwellers. The same word may be found in the name of the Banu Ifran from Algeria and Tripolitania ,
3111-537: A portion of the lake is included in Lake Malawi National Park . Lake Malawi is a meromictic lake , meaning that its water layers do not mix. The permanent stratification of Lake Malawi's water and the oxic- anoxic boundary are maintained by moderately small chemical and thermal gradients . Lake Malawi is between 560 kilometres (350 mi) and 580 kilometres (360 mi) long, and about 75 kilometres (47 mi) wide at its widest point. The lake has
3294-404: A slightly greater average elevation, and marked by some distinct features. It is formed by a widening out of the eastern axis of high ground, which becomes subdivided into a number of zones running north and south and consisting in turn of ranges, tablelands and depressions. The most striking feature is the existence of two great lines of depression, due largely to the subsidence of whole segments of

Another smaller depression in the far north reaches a depth of 528 m (1,732 ft). The southern half of the lake is shallower; less than 400 m (1,300 ft) in the south-central part and less than 200 m (660 ft) in
3660-464: A transition from " informal imperialism " – military influence and economic dominance – to direct rule. Imperial rule by Europeans continued until after the conclusion of World War II , when almost all remaining colonial territories gradually obtained formal independence. Independence movements in Africa gained momentum following World War II, which left the major European powers weakened. In 1951, Libya,

The water is very clear for a lake and the visibility can be up to 20 m (66 ft), but slightly less than half this figure is more common and it is below 3 m (10 ft) in muddy bays. However, during the rainy season months of January to March, the waters are more muddy due to muddy river inflows. The Portuguese trader Candido José da Costa Cardoso

(The rarity of the air and the great radiation during the night cause the temperature in the Sahara to fall occasionally to freezing point.) Farther south, the heat
4575-765: Is lost in a saline depression near the Gulf of Aden. Between the basins of the Atlantic and Indian Oceans, there is an area of inland drainage along the centre of the Ethiopian plateau, directed chiefly into the lakes in the Great Rift Valley . The largest river is the Omo , which, fed by the rains of the Ethiopian highlands, carries down a large body of water into Lake Turkana . The rivers of Africa are generally obstructed either by bars at their mouths, or by cataracts at no great distance upstream. But when these obstacles have been overcome,

Farther south, the Limpopo drains a portion of the interior plateau, but breaks through the bounding highlands on the side of the continent nearest its source. The Rovuma , Rufiji and Tana principally drain the outer slopes of the African Great Lakes highlands. In the Horn region to the north,
4941-787: Is not always to be taken literally. Africa is considered by most paleoanthropologists to be the oldest inhabited territory on Earth, with the Human species originating from the continent. During the mid-20th century, anthropologists discovered many fossils and evidence of human occupation perhaps as early as seven million years ago ( Before present , BP). Fossil remains of several species of early apelike humans thought to have evolved into modern humans, such as Australopithecus afarensis radiometrically dated to approximately 3.9–3.0 million years BP, Paranthropus boisei (c. 2.3–1.4 million years BP) and Homo ergaster (c. 1.9 million–600,000 years BP) have been discovered.

Pelagic zooplanktonic species include two cladocerans ( Diaphanosoma excisum and Bosmina longirostris ), three copepods ( Tropodiaptomus cunningtoni , Thermocyclops neglectus and Mesocyclops aequatorialis ), and several ostracods (including both described and undescribed species ). Lake Malawi is famous for the huge swarms of tiny, harmless lake flies, Chaoborus edulis . These swarms, typically appearing far out over water, can be mistaken for plumes of smoke and were also noticed by David Livingstone when he visited

Fossorochromis rostratus is an "aberrant" hap that often sifts mouthfuls of sand to extract small food organisms. 6. Like many mbuna , Pseudotropheus saulosi is a small cichlid where both male (blue and black) and female (yellow) are colorful. Lake Malawi is noted for being the site of evolutionary radiations among several groups of animals, most notably cichlid fish. There are at least 700 cichlid species in Lake Malawi, with some estimating that

Others, however, are shallow, and hardly reach the steep sides of the valleys in the dry season. Such are Lake Rukwa , in a subsidiary depression north of Nyasa, and Eiassi and Manyara in the system of the Great Rift Valley. Lakes of the broad type are of moderate depth, the deepest sounding in Lake Victoria being under 90 m (300 ft). Besides

The gradual decline of slave-trading, prompted by a lack of demand for slaves in the New World , increasing anti-slavery legislation in Europe and America, and the British Royal Navy's increasing presence off the West African coast, obliged African states to adopt new economies. Between 1808 and 1860,
13176-579: The 16th century to 1975, after the Estado Novo regime was overthrown in a military coup in Lisbon . Rhodesia unilaterally declared independence from the United Kingdom in 1965, under the white minority government of Ian Smith , but was not internationally recognized as an independent state (as Zimbabwe ) until 1980, when black nationalists gained power after a bitter guerrilla war . Although South Africa
13359-590: The 1st and 4th cataracts of the Nile . The 4th dynasty oversaw the height of the Old Kingdom , and constructed many great pyramids . Under the 6th dynasty power gradually decentralised to the nomarchs, culminating in the disintegration of the kingdom, exacerbated by drought and famine, thus commencing the First Intermediate Period in 2200 BC. This shattered state would last until 2055 BC when
13542-567: The 2nd century BC Mauretania fought alongside Numidia's Jugurtha in the Jugurthine War against the Romans after he had usurped the Numidian throne from a Roman ally. Together they inflicted heavy casualties that quaked the Roman Senate , with the war only ending inconclusively when Mauretania's Bocchus I sold out Jugurtha to the Romans. At the turn of the millennium, they both would face
13725-663: The 4th millennium BC the Congo Basin was inhabited by the Bambenga , Bayaka , Bakoya , and Babongo in the west, the Bambuti in the east , and the Batwa who were widely scattered and also present in the Great Lakes region ; together they are grouped as Pygmies . On the later-named Swahili coast there were Cushitic -speaking peoples, and the Khoisan (a neologism for the Khoekhoe and San ) in
13908-416: The 4th millennium BC, which had crucially developed iron metallurgy by 1200 BC, in both smelting and forging for tools and weapons. Extensive east-west belts of deserts , grasslands , and forests from north to south were crucial for the moulding of their respective societies and meant that prior to the accession of trans-Saharan trade routes , symbiotic trade relations developed in response to
14091-439: The African Great Lakes, especially Tanganyika , which some geologists have considered to represent an old arm of the sea, dating from a time when the whole central Congo basin was under water; others holding that the lake water has accumulated in a depression caused by subsidence. The former view is based on the existence in the lake of organisms of a decidedly marine type. They include jellyfish, molluscs, prawns, crabs, etc. With
14274-420: The African Great Lakes, the principal lakes on the continent are: Lake Chad , in the northern inland watershed; Bangweulu and Mweru , traversed by the head-stream of the Congo; and Lake Mai-Ndombe and Ntomba (Mantumba), within the great bend of that river. All, except possibly Mweru, are more or less shallow, and Lake Chad appears to be drying up. Divergent opinions have been held as to the mode of origin of
14457-513: The African continent. Algeria is Africa's largest country by area, and Nigeria is its largest by population. African nations cooperate through the establishment of the African Union , which is headquartered in Addis Ababa . Africa straddles the equator and the prime meridian . It is the only continent to stretch from the northern temperate to the southern temperate zones. The majority of
14640-678: The Assyrians in 663 BC in reprisal for their expansion towards the Assyrian Empire . The Assyrians installed a puppet dynasty that later gained independence and once more unified Egypt , until they were conquered by the Achaemenid Empire in 525 BC. Egypt regained independence under the 28th dynasty in 404 BC but they were reconquered by the Achaemenids in 343 BC. The conquest of Achaemenid Egypt by Alexander
14823-499: The Atlas chain, the elevated rim of the continent is almost wanting. Much of Africa is made up of plains of the pediplain and etchplain type often occurring as steps. The etchplains are commonly associated with laterite soil and inselbergs . Inselberg -dotted plains are common in Africa including Tanzania , the Anti-Atlas of Morocco , Namibia , and the interior of Angola . One of
15006-399: The Atlas mountains. Of the rivers flowing to the Indian Ocean , the only one draining any large part of the interior plateaus is the Zambezi , whose western branches rise in the western coastal highlands. The main stream has its rise in 11°21′3″ S 24°22′ E, at an elevation of 1,500 m (4,900 ft). It flows to the west and south for a considerable distance before turning eastward. All
15189-553: The British West Africa Squadron seized approximately 1,600 slave ships and freed 150,000 Africans who were aboard. Action was also taken against African leaders who refused to agree to British treaties to outlaw the trade, for example against "the usurping King of Lagos ", deposed in 1851. Anti-slavery treaties were signed with over 50 African rulers. The largest powers of West Africa (the Asante Confederacy ,
15372-512: The Earth's crust, the lowest parts of which are occupied by vast lakes. Towards the south the two lines converge and give place to one great valley (occupied by Lake Nyasa ), the southern part of which is less distinctly due to rifting and subsidence than the rest of the system. Farther north the western hollow, known as the Albertine Rift , is occupied for more than half its length by water, forming
15555-635: The Great in 332 BC marked the beginning of Hellenistic rule and the installation of the Macedonian Ptolemaic dynasty in Egypt. The Ptolemaics lost their holdings outside of Africa to the Seleucids in the Syrian Wars , expanded into Cyrenaica and subjugated Kush in the 3rd century BC. In the 1st century BC, Ptolemaic Egypt became entangled in a Roman civil war , leading to its conquest by
15738-482: The Guinea coast the harmattan . This wind is not invariably hot; its great dryness causes so much evaporation that cold is not infrequently the result. Similar dry winds blow from the Kalahari Desert in the south. On the eastern coast the monsoons of the Indian Ocean are regularly felt, and on the southeast hurricanes are occasionally experienced. The climate of Africa lends itself to certain environmental diseases,
15921-564: The Iberian peninsula during the eleventh century. The Banu Hilal and Banu Ma'qil were a collection of Arab Bedouin tribes from the Arabian Peninsula who migrated westwards via Egypt between the eleventh and thirteenth centuries. Their migration resulted in the fusion of the Arabs and Berbers, where the locals were Arabized , and Arab culture absorbed elements of the local culture, under
16104-589: The Malawi system, which also includes nearby smaller Lake Malombe and the upper Shire River. Many of these have become popular among aquarium owners due to their bright colors. Recreating a Lake Malawi biotope to host cichlids became quite popular in the aquarium hobby. Most Malawi cichlids are found in relatively shallow coastal waters, but Diplotaxodon has been recorded down to depths of 200–220 m (660–720 ft) and several (especially Diplotaxodon , Rhamphochromis and Copadichromis quadrimaculatus ) are known from pelagic waters. The cichlids of
16287-522: The Niger, which flows half of its length through the arid areas. The largest lakes are the following: Lake Victoria (Lake Ukerewe), Lake Chad, in the centre of the continent, Lake Tanganyika, lying between the Democratic Republic of Congo, Burundi, Tanzania and Zambia. There is also the considerably large Lake Malawi stretching along the eastern border of Malawi. There are also numerous water dams throughout
16470-550: The Persian prophet Mani to consider Aksum as one of the four great powers of the 3rd century AD alongside Persia , Rome , and China . In the 4th century AD Aksum's king converted to Christianity and Aksum's population, who had followed syncretic mixes of local beliefs , slowly followed. The end of the 5th century saw Aksum allied with the Byzantine Empire , who viewed themselves as defenders of Christendom , balanced against
16653-504: The Red Sea. Though generally of slight elevation, it contains mountain ranges with peaks rising to 2,400 m (7,900 ft) Bordered N.W. by the Atlas range, to the northeast a rocky plateau separates it from the Mediterranean ; this plateau gives place at the extreme east to the delta of the Nile. That river (see below) pierces the desert without modifying its character. The Atlas range ,
16836-558: The Romans in the Second Punic War, Mauretania , a Mauri tribal kingdom and home of the legendary King Atlas , and various tribes such as Garamantes , Musulamii , and Bavares . The Third Punic War would result in Carthage's total defeat in 146 BC and the Romans established the province of Africa , with Numidia assuming control of many of Carthage's African ports. Towards the end of
17019-756: The Sahara region was becoming increasingly dry and hostile. Around 3500 BC, due to a tilt in the Earth's orbit , the Sahara experienced a period of rapid desertification. The population trekked out of the Sahara region towards the Nile Valley below the Second Cataract where they made permanent or semi-permanent settlements. A major climatic recession occurred, lessening the heavy and persistent rains in Central and Eastern Africa . Since this time, dry conditions have prevailed in Eastern Africa and, increasingly during
17202-517: The Saharan climate started to become drier at an exceedingly fast pace. This climate change caused lakes and rivers to shrink significantly and caused increasing desertification . This, in turn, decreased the amount of land conducive to settlements and encouraged migrations of farming communities to the more tropical climate of West Africa. During the first millennium BC, a reduction in wild grain populations related to changing climate conditions facilitated
17385-453: The Shire River are vital for the economy as the water resources support hydropower, irrigation and downstream biodiversity. Concerns have been raised over the future climate change impacts of Lake Malawi due to the recent decline in lake levels and the overall drying trend. The climate in the lake region is already experiencing changes, with the temperatures predicted to increase throughout
17568-416: The actual figure is as high as 1,000 species. The actual number is labelled with some uncertainty because of the many undescribed species and the extreme variation among some species, making the task of delimiting them very complex. Except for four species ( Astatotilapia calliptera , Coptodon rendalli , Oreochromis shiranus and Serranochromis robustus ), all cichlids in the lake are endemic to
17751-520: The adults die. The larvae are an important food source for fish, and the adult flies are important both to birds and local people, who collect them to make kungu cakes/burgers, a local delicacy with a very high protein content. In January 2015, a sediment control tank collapsed at the Paladin Energy -owned uranium mine in Northern Malawi after a high intensity rain storm hit the area. It
17934-570: The area of land over 3,000 m (9,800 ft) is also quite insignificant, being represented almost entirely by individual peaks and mountain ranges. Moderately elevated tablelands are thus the characteristic feature of the continent, though the surface of these is broken by higher peaks and ridges. (So prevalent are these isolated peaks and ridges that a specialised term— Inselberg-Landschaft , island mountain landscape—has been adopted in Germany to describe this kind of country, thought to be in great part
18117-432: The bilharzia parasite. Unlike Lake Tanganyika with its many endemic freshwater crabs and shrimp, there are few such species in Lake Malawi. The Malawi blue crab, Potamonautes lirrangensis ( syn. P. orbitospinus ), is the only crab in the lake and it is not endemic. The atyid shrimp Caridina malawensis is endemic to the lake, but it is poorly known and has historically been confused with C. nilotica , which
18300-511: The border. The wrangle in this dispute occurred when the British colonial government, just after they had captured Tanganyika from Germany, placed all of the waters of the lake under a single jurisdiction, that of the territory of Nyasaland , without a separate administration for the Tanganyikan portion of the surface. Later in colonial times, two jurisdictions were established. The dispute came to
18483-532: The continent and its countries are in the Northern Hemisphere , with a substantial portion and a number of countries in the Southern Hemisphere . Most of the continent lies in the tropics, except for a large part of Western Sahara , Algeria , Libya and Egypt , the northern tip of Mauritania , and the entire territories of Morocco , Ceuta , Melilla , and Tunisia , which in turn are located above
18666-463: The continent as a whole has trended towards more democratic governance. Upon independence an overwhelming majority of Africans lived in extreme poverty . The continent suffered from the lack of infrastructural or industrial development under colonial rule, along with political instability. With limited financial resources or access to global markets, relatively stable countries such as Kenya still experienced only very slow economic development. Only
18849-424: The continent most vulnerable to climate change . The history of Africa is long, complex, and varied, and has often been under-appreciated by the global historical community . In African societies the oral word is revered, and they have generally recorded their history via oral tradition , which has led anthropologists to term them oral civilisations, contrasted with literate civilisations which pride
19032-478: The continent show both the east-to-west direction characteristic, at least in the eastern hemisphere, of the more northern parts of the world, and the north-to-south direction seen in the southern peninsulas. Africa is thus mainly composed of two segments at right angles, the northern running from east to west, and the southern from north to south. The average elevation of the continent approximates closely to 600 m (2,000 ft) above sea level, roughly near to
19215-457: The continent's south. The Bantu expansion constituted a major series of migrations of Bantu peoples from central Africa to eastern and southern Africa and was substantial in the settling of the continent. Commencing in the 2nd millennium BC, the Bantu began to migrate from Cameroon to central, eastern, and southern Africa, laying the foundations for future states such as the Kingdom of Kongo in
19398-565: The continent, while the Kunene, Kwanza, Ogowe and Sanaga drain the west coastal highlands of the southern limb; the Volta , Komoe, Bandama, Gambia and Senegal the highlands of the western limb. North of the Senegal, for over 1,500 km (930 mi) of coast, the arid region reaches to the Atlantic. Farther north are the streams, with comparatively short courses, reaching the Atlantic and Mediterranean from
19581-473: The continent. Africa, particularly Eastern Africa , is widely accepted to be the place of origin of humans and the Hominidae clade , also known as the great apes . The earliest hominids and their ancestors have been dated to around 7 million years ago, and Homo sapiens (modern human) are believed to have originated in Africa 350,000 to 260,000 years ago. Africa is also considered by anthropologists to be
19764-606: The continent: Kariba on the river of Zambezi, Asuan in Egypt on the river of Nile, and Akosombo, the continent's biggest dam on the Volta River in Ghana (Fobil 2003). The high lake plateau of the African Great Lakes region contains the headwaters of both the Nile and the Congo . The break-up of Gondwana in Late Cretaceous and Cenozoic times led to a major reorganization of the river courses of various large African rivers including
19947-509: The corresponding area is 1,000,000 km (390,000 sq mi). West of Lake Chad is the basin of the Niger , the third major river of Africa. With its principal source in the far west, it reverses the direction of flow exhibited by the Nile and Congo, and ultimately flows into the Atlantic ;— a fact that eluded European geographers for many centuries. An important branch, however —
20130-470: The country. The lake is about 350 kilometres (220 mi) southeast of Lake Tanganyika , another of the great lakes of the East African Rift. The Lake Malawi National Park is located at the southern end of the lake. Malawi is one of the major Rift Valley lakes and an ancient lake . The lake lies in a valley formed by the opening of the East African Rift , where the African tectonic plate
20313-504: The direction of the tropics, where the sun is overhead but once. Snow falls on all the higher mountain ranges, and on the highest the climate is thoroughly Alpine. The countries bordering the Sahara are much exposed to a very dry wind, full of fine particles of sand, blowing from the desert towards the sea. Known in Egypt as the khamsin , on the Mediterranean as the sirocco , it is called on
20496-428: The earliest instances of agriculture in human history. Its cultivation would gradually spread across Africa, before spreading to India around 2000 BC. People around modern-day Mauritania started making pottery and built stone settlements (e.g., Tichitt , Oualata ). Fishing, using bone-tipped harpoons , became a major activity in the numerous streams and lakes formed from the increased rains. In West Africa,
20679-524: The east and west of the continent the bordering highlands are continued as strips of plateau parallel to the coast, the Ethiopian mountains being continued northwards along the Red Sea coast by a series of ridges reaching in places a height of 2,000 m (6,600 ft). In the west the zone of high land is broader but somewhat lower. The most mountainous districts lie inland from the head of the Gulf of Guinea (Adamawa, etc.), where heights of 1,800 to 2,400 m (5,900 to 7,900 ft) are reached. Exactly at
20862-535: The end of the Ice ages , estimated to have been around 10,500 BC, the Sahara had again become a green fertile valley, and its African populations returned from the interior and coastal highlands in sub-Saharan Africa , with rock art paintings depicting a fertile Sahara and large populations discovered in Tassili n'Ajjer dating back perhaps 10 millennia. However, the warming and drying climate meant that by 5,000 BC,
21045-625: The evolution of Homo sapiens approximately 350,000 to 260,000 years BP in Africa, the continent was mainly populated by groups of hunter-gatherers . These first modern humans left Africa and populated the rest of the globe during the Out of Africa II migration dated to approximately 50,000 years BP, exiting the continent either across Bab-el-Mandeb over the Red Sea , the Strait of Gibraltar in Morocco, or
21228-477: The exception of Madagascar , the African islands are small. Madagascar, with an area of 587,041 km (226,658 sq mi), is, after Greenland , New Guinea and Borneo , the fourth largest island on the Earth. It lies in the Indian Ocean , off the southeast coast of the continent, from which it is separated by the deep Mozambique Channel , 400 km (250 mi) wide at its narrowest point. Madagascar in its general structure, as in flora and fauna, forms
21411-647: The expansion of farming communities and the rapid adoption of rice cultivation around the Niger River. By the first millennium BC, ironworking had been introduced in Northern Africa. Around that time it also became established in parts of sub-Saharan Africa, either through independent invention there or diffusion from the north and vanished under unknown circumstances around 500 AD, having lasted approximately 2,000 years, and by 500 BC, metalworking began to become commonplace in West Africa. Ironworking
21594-668: The far south. The lake has shorelines on western Mozambique , eastern Malawi , and southern Tanzania . The largest river flowing into it is the Ruhuhu River , and there is an outlet at its southern end, the Shire River , a tributary that flows into the Zambezi River in Mozambique. Evaporation accounts for more than 80% of the water loss from the lake, considerably more than the outflowing Shire River. The outflows from Lake Malawi into
21777-450: The flood-water), it separates the great desert with its fertile watershed, and enters the Mediterranean at a vast delta. The most remote head-stream of the Congo is the Chambezi , which flows southwest into the marshy Lake Bangweulu . From this lake issues the Congo, known in its upper course by various names. Flowing first south, it afterwards turns north through Lake Mweru and descends to
21960-542: The forest-clad basin of west equatorial Africa. Traversing this in a majestic northward curve, and receiving vast supplies of water from many great tributaries, it finally turns southwest and cuts a way to the Atlantic Ocean through the western highlands. The area of the Congo basin is greater than that of any other river except the Amazon, while the African inland drainage area is greater than that of any continent but Asia, where
22143-502: The growth and expansion of Aksum in the 1st century BC. Along the Horn's coast there were many ancient Somali city-states that thrived off of the wider Red Sea trade and transported their cargo via beden , exporting myrrh , frankincense , spices , gum , incense , and ivory , with freedom from Roman interference causing Indians to give the cities a lucrative monopoly on cinnamon from ancient India . The Kingdom of Aksum grew from
22326-570: The head of the gulf the great peak of the Cameroon, on a line of volcanic action continued by the islands to the south-west, has a height of 4,075 m (13,369 ft), while Clarence Peak, in Fernando Po , the first of the line of islands, rises to over 2,700 m (8,900 ft). Towards the extreme west the Futa Jallon highlands form an important diverging point of rivers, but beyond this, as far as
22509-443: The historical process is largely a communal one, with eyewitness accounts, hearsay , reminiscences, and occasionally visions , dreams, and hallucinations, crafted into oral traditions . Time is sometimes mythical and social, and truth generally viewed as relativist . Oral tradition can be exoteric or esoteric . It speaks to people according to their understanding, unveiling itself in accordance with their aptitudes, and
22692-526: The idea of "high Africa" and "low Africa" to help distinguish the difference in Geography; "high Africa" extending from Ethiopia down south to South Africa and the Cape of Good Hope while "low Africa" representing the plains of the rest of the continent. The following table gives the details of the chief mountains and ranges of the continent: From the outer margin of the African plateaus, a large number of streams run to
22875-509: The kingdoms of Lower Egypt and Upper Egypt in northeast Africa . Around 3100 BC Upper Egypt conquered Lower Egypt to unify Egypt under the 1st dynasty , with the process of consolidation and assimilation completed by the time of the 3rd dynasty who formed the Old Kingdom of Egypt in 2686 BC. The Kingdom of Kerma emerged around this time to become the dominant force in Nubia , controlling territory as large as Egypt between
23058-499: The lake are divided into two groups and the vast majority of the species are haplochromines . The sister species to the Malawi haplochromines is Astatotilapia sp. Ruaha (a currently undescribed species from Great Ruaha River ), and these two separated between 2.13 and 6.76 million years ago (mya). The earliest divergence within the Malawi haplochromines occurred between 1.20 and 4.06 mya, but most radiations in this group are far younger; in extreme cases species may have diverged only
23241-493: The lake dried out almost completely, leaving only one or two relatively small, highly alkaline and saline lakes in what currently are Malawi's deepest parts. A water chemistry resembling the current conditions only appeared about 60,000 years ago. Major low-water periods are estimated to have occurred about 1.6 to 1.0–0.57 million years ago (where it might have dried out completely), 420,000 to 250,000–110,000 years ago, about 25,000 years ago and 18,000–10,700 years ago. During
23424-469: The lake's surface area between Malawi and Tanzania is under dispute. Tanzania claims that the international border runs through the middle of the lake. On the other hand, Malawi claims the whole of the surface of this lake that is not in Mozambique, including the waters that are next to the shoreline of Tanzania. Both sides cite the Heligoland Treaty of 1890 between Great Britain and Germany concerning
23607-491: The lake, and two non-endemic species ( B. globosus and B. forskalli ) in lagoons separated from it. The latter species are known intermediate hosts of bilharzia, and larvae of the parasite were detected in water containing these, but in experiments C. Wright of the British Museum of Natural History was unable to infect the two species endemic to the lake with the parasites. The field workers, who spent many hours on and in
23790-401: The lake, did not find either B. globosus or B. forskalli in the lake itself. More recently, the disease has become a problem in the lake itself as the endemic B. nyassanus has become an intermediate host. This change, first noticed in the mid-1980s, is possibly related to a decline in snail-eating cichlids (for example, Trematocranus placodon ) due to overfishing and/or a new strain of
23973-811: The lake, the Hermann von Wissmann , commanded by Captain Berndt. Rhoades's crew found the Hermann von Wissmann in a bay near Sphinxhaven , in German East African territorial waters. Gwendolen disabled the German boat with a single cannon shot from a range of about 1,800 metres (2,000 yd). This brief conflict was hailed by The Times in England as the British Empire's first naval victory of World War I. The partition of
24156-411: The lake. The aquatic larvae feed on zooplankton, spending the day at the bottom and the night in the upper water levels. When they pupate they float to the surface and transform into adult flies. The adults are very short-lived and the swarms, which can be several hundred metres tall and often have a spiraling shape, are part of their mating behaviour. They lay their eggs at the water's surface and
24339-453: The largest number of megafauna species, as it was least affected by the extinction of the Pleistocene megafauna . However, Africa also is heavily affected by a wide range of environmental issues , including desertification, deforestation, water scarcity , and pollution . These entrenched environmental concerns are expected to worsen as climate change impacts Africa . The UN Intergovernmental Panel on Climate Change has identified Africa as
24522-399: The largest tributaries, including the Shire, the outflow of Lake Nyasa , flow down the southern slopes of the band of high ground stretching across the continent from 10° to 12° S. In the southwest, the Zambezi system interlaces with that of the Taukhe (or Tioghe), from which it at times receives surplus water. The rest of the water of the Taukhe, known in its middle course as the Okavango ,
24705-440: The last 200 years, in Ethiopia . The domestication of cattle in Africa preceded agriculture and seems to have existed alongside hunter-gatherer cultures. It is speculated that by 6,000 BC, cattle were domesticated in North Africa. In the Sahara-Nile complex, people domesticated many animals, including the donkey and a small screw-horned goat that was common from Algeria to Nubia . Between 10,000 and 9,000 BC, pottery
24888-428: The latter of these, the effluents of the other two lakes add their waters. Issuing from there, the Nile flows northward, and between the latitudes of 7 and 10 degrees north it traverses a vast marshy level, where its course is liable to being blocked by floating vegetation. After receiving the Bahr-el-Ghazal from the west and the Sobat , Blue Nile and Atbara from the Ethiopian Highlands (the chief gathering ground of
25071-469: The mbuna, a name used both locally and popularly, which means "rockfish" in Tonga . They are found at rocky outcrops, territorially aggressive (although commonly found in high densities) and often specialised aufwuchs feeders. The mbuna species tend to be relatively small, mostly less than 13 cm (5 in) long, and often both sexes are brightly colored with males having egg-shaped yellow spots on their anal fin (a feature particularly prevalent in
25254-401: The mbuna, but not exclusive to this group). The second group, the tilapia , comprises only six species in two genera in Lake Malawi: The redbreast tilapia ( Coptodon rendalli ), a widespread African species, is the only substrate-spawning cichlid in the lake. This large cichlid mainly feeds on macrophytes . The remaining are five mouthbrooding species of Oreochromis ; four chambo in
25437-423: The mean elevation of both North and South America , but considerably less than that of Asia , 950 m (3,120 ft). In contrast with other continents, it is marked by the comparatively small area of either very high or very low ground, lands under 180 m (590 ft) occupying an unusually small part of the surface; while not only are the highest elevations inferior to those of Asia or South America, but
25620-444: The middle of the lake their boundary with the exception of Chizumulu Island and Likoma Island , which were kept by the British and are now part of Malawi. MV Chauncy Maples began service on the lake in 1901 as the SS Chauncy Maples : a floating clinic and church for the Universities' Mission to Central Africa . She later served as a ferry and is currently being renovated into a mobile clinic at Monkey Bay . The renovation
25803-488: The most genetically diverse continent as a result of being the longest inhabited. In the 4th and 3rd millennia BC Ancient Egypt , Kerma , Punt , and the Tichitt Tradition emerged in North , East and West Africa , while from 4000 BC until 1000 AD the Bantu expansion was substantial in laying the foundations for societies and states in Central , East , and Southern Africa . Some African empires include Wagadu , Mali , Songhai , Sokoto , Ife , Benin , Asante ,
25986-399: The most lucrative trading locations in the Gulf of Tunis . Phoenician settlements subsequently grew into Ancient Carthage after gaining independence from Phoenicia in the 6th century BC, and they would build an extensive empire and a strict mercantile network, all secured by one of the largest and most powerful navies in the ancient Mediterranean . Carthage would meet its demise in
26169-444: The most popular are the four species of chambo, consisting of any one of four species in the subgenus Nyasalapia ( Oreochromis karongae , O. lidole , O. saka and O. squamipinnis ), as well as the closely related O. shiranus . Other species that support important fisheries include the Lake Malawi sardine ( Engraulicypris sardella ) and the large kampango catfish ( Bagrus meridionalis ). Most fishing provides food for
26352-445: The most serious of which are: malaria , sleeping sickness and yellow fever . Malaria is the most deadly environmental disease in Africa. It is transmitted by a genus of mosquito ( anopheles mosquito ) native to Africa, and can be contracted over and over again. There is not yet a vaccine for malaria, which makes it difficult to prevent the disease from spreading in Africa. Recently, the dissemination of mosquito netting has helped lower
26535-402: The most southerly point, Cape Agulhas in South Africa , 34°51′15″ S, is a distance approximately of 8,000 km (5,000 mi); from Cap-Vert , 17°31′13″W, the westernmost point, to Ras Hafun in the Somali Puntland region, in the Horn of Africa , 51°27′52″ E, the most easterly projection, is a distance (also approximately) of 7,400 km (4,600 mi). The main structural lines of
26718-402: The most wideaspread plain is the African Surface , a composite etchplain occurring across much of the continent. The area between the east and west coast highlands, which north of 17° N is mainly desert, is divided into separate basins by other bands of high ground, one of which runs nearly centrally through North Africa in a line corresponding roughly with the curved axis of the continent as
26901-467: The north-west coast are the Canary and Cape Verde archipelagoes. which, like some small islands in the Gulf of Guinea, are of volcanic origin. The South Atlantic Islands of Saint Helena and Ascension are classed as Africa but are situated on the Mid-Atlantic Ridge halfway to South America . Lying almost entirely within the tropics, and equally to north and south of the equator, Africa does not show excessive variations of temperature. Great heat
27084-415: The north-westerly part of the continent, between its seaward and landward heights encloses elevated steppes in places 160 km (99 mi) broad. From the inner slopes of the plateau numerous wadis take a direction towards the Sahara. The greater part of that now desert region is, indeed, furrowed by old water-channels. The mountains are an exception to Africa's general landscape. Geographers came up with
27267-439: The official religion, built mosques, and brought to Gao Muslim scholars, including al-Maghili (d.1504), the founder of an important tradition of Sudanic African Muslim scholarship. By the eleventh century, some Hausa states – such as Kano , Jigawa , Katsina , and Gobir – had developed into walled towns engaging in trade, servicing caravans , and the manufacture of goods. Until the fifteenth century, these small states were on
27450-463: The only one comparable to those of the western trough being Lake Turkana or Basso Norok. A short distance east of this rift valley is Mount Kilimanjaro – with its two peaks Kibo and Mawenzi, the latter being 5,889 m (19,321 ft), and the culminating point of the whole continent – and Mount Kenya , which is 5,184 m (17,008 ft). Hardly less important is the Ruwenzori Range , over 5,060 m (16,600 ft), which lies east of
27633-509: The open-water (although often not far from sand or rocks) utaka that feed in schools on zooplankton and typically are of medium size, and finally a subgroup of "aberrant" species that essentially are defined by them not fitting clearly into the other subgroups. Adult male haps generally display bright colors, while juveniles of both sexes and adult females typically show a silvery or grey coloration with sometimes irregular black bars or other markings. The second main haplochromine group are
27816-410: The opportunities afforded by north–south diversity in ecosystems. Various civilisations prospered in this period. From 4000 BC, the Tichitt culture in modern-day Mauritania and Mali was the oldest known complexly organised society in West Africa, with a four tiered hierarchical social structure. Other civilisations include the Kintampo culture from 2500 BC in modern-day Ghana ,
27999-401: The outer highlands, and becoming constantly drier owing to the heating effects of the burning soil of the interior; while the scarcity of mountain ranges in the more central parts likewise tends to prevent condensation. In the inter-tropical zone of summer precipitation, the rainfall is greatest when the sun is vertical or soon after. It is therefore greatest of all near the equator, where the sun
28182-434: The peak of the low-water period between 1390 and 1860 AD , it may have been 120–150 m (390–490 ft) below current water levels. The lake's water is alkaline ( pH 7.7–8.6) and warm with a typical surface temperature between 24 and 29 °C (75–84 °F), while deep sections typically are about 22 °C (72 °F). The thermocline is located at a depth of 40–100 m (130–330 ft). The oxygen limit
28365-421: The periphery of the major Sudanic empires of the era, paying tribute to Songhai to the west and Kanem-Borno to the east. Slavery had long been practiced in Africa. Between the 15th and the 19th centuries, the Atlantic slave trade took an estimated 7–12 million slaves to the New World. In addition, more than 1 million Europeans were captured by Barbary pirates and sold as slaves in North Africa between
28548-474: The predecessor to the African Union. The nascent countries decided to keep their colonial borders, with traditional power structures used in governance to varying degrees. Afri was a Latin name used to refer to the inhabitants of what was then known as northern Africa , located west of the Nile river, and in its widest sense referring to all lands south of the Mediterranean , also known as Ancient Libya . This name seems to have originally referred to
28731-440: The rainiest regions of the world. The rainiest district in all Africa is a strip of coastland west of Mount Cameroon , where there is a mean annual rainfall of about 10,000 mm (394 in) as compared with a mean of 11,600 mm (457 in) at Cherrapunji , in Meghalaya , India . The two distinct rainy seasons of the equatorial zone, where the sun is vertical at half-yearly intervals, become gradually merged into one in
28914-411: The rate of malaria. Yellow fever is a disease also transmitted by mosquitoes native to Africa. Unlike malaria, it cannot be contracted more than once. Like chicken pox, it is a disease that tends to be severe the later in life a person contracts the disease. Sleeping sickness, or African trypanosomiasis, is a disease that usually affects animals, but has been known to be fatal to some humans as well. It
29097-432: The result of wind action.) As a general rule, the higher tablelands lie to the east and south, while a progressive diminution in altitude towards the west and north is observable. Apart from the lowlands and the Atlas Mountains , the continent may be divided into two regions of higher and lower plateaus, the dividing line (somewhat concave to the northwest) running from the middle of the Red Sea to about 6 degrees south on
29280-444: The rivers and lakes afford a vast network of navigable waters. North of the Congo basin, and separated from it by a broad undulation of the surface, is the basin of Lake Chad — a flat-shored, shallow lake filled principally by the Chari coming from the southeast. The principal lakes of Africa are situated in the African Great Lakes plateau. The lakes found within the Great Rift Valley have steep sides and are very deep. This
29463-426: The same fate as Carthage and be conquered by the Romans who established Mauretania and Numidia as provinces of their empire, while Musulamii , led by Tacfarinas , and Garamantes were eventually defeated in war in the 1st century AD however weren't conquered. In the 5th century AD the Vandals conquered north Africa precipitating the fall of Rome . Swathes of indigenous peoples would regain self-governance in
29646-406: The sea with comparatively short courses, while the larger rivers flow for long distances on the interior highlands, before breaking through the outer ranges. The main drainage of the continent is to the north and west, or towards the basin of the Atlantic Ocean . To the main African rivers belong: Nile (the longest river of Africa), Congo (river with the highest water discharge on the continent) and
29829-446: The south of the continent being narrower than the north, the influence of the surrounding ocean is more felt. The most important climatic differences are due to variations in the amount of rainfall. The wide heated plains of the Sahara, and in a lesser degree the corresponding zone of the Kalahari in the south, have an exceedingly scanty rainfall, the winds which blow over them from the ocean losing part of their moisture as they pass over
30012-524: The subgenus Nyasalapia ( O. karongae , O. lidole , O. saka and O. squamipinnis ) that are endemic to the Lake Malawi system, as well as the closely related O. shiranus , which also is found in Lake Chilwa . The Malawi Oreochromis mainly feed on phytoplankton , reach lengths up to 26–42 cm (10–17 in) depending on the exact species, and are mostly black or silvery-gray with relatively indistinct dark bars. Male chambo have unique genital tassels when breeding, which aid in egg fertilisation in
30195-425: The two continents by the geographer Ptolemy (85–165 CE), indicating Alexandria along the Prime Meridian and making the isthmus of Suez and the Red Sea the boundary between Asia and Africa. As Europeans came to understand the real extent of the continent, the idea of "Africa" expanded with their knowledge. Other etymological hypotheses have been postulated for the ancient name "Africa": In African societies,
30378-433: The unifying framework of Islam. Following the breakup of Mali, a local leader named Sonni Ali (1464–1492) founded the Songhai Empire in the region of middle Niger and the western Sudan and took control of the trans-Saharan trade. Sonni Ali seized Timbuktu in 1468 and Jenne in 1473, building his regime on trade revenues and the cooperation of Muslim merchants. His successor Askia Mohammad I (1493–1528) made Islam
30561-410: The unpredictable and extremely violent gales that sweep through the area, he also referred to it as the Lake of Storms. On 16 August 1914, Lake Malawi was the scene of a brief naval battle during World War I . The British gunboat SS Gwendolen , commanded by a Captain Rhoades, received orders from the British Empire's high command to "sink, burn, or destroy" the German Empire's only gunboat on
30744-438: The west coast. Africa can be divided into a number of geographic zones: There are many plateaus in Africa. The high southern and eastern plateaus, rarely falling below 600 m (2,000 ft), have a mean elevation of about 1,000 m (3,300 ft). The South African plateau , as far as about 12° S, is bounded east, west and south by bands of high ground which fall steeply to the coasts. On this account South Africa has
30927-418: The western trough. Other volcanic peaks rise from the floor of the valleys, some of the Kirunga (Mfumbiro) group, north of Lake Kivu, being still partially active. This could cause most of the cities and states to be flooded with lava and ash. The third division of the higher region of Africa is formed by the Ethiopian Highlands , a rugged mass of mountains forming the largest continuous area of its altitude in
31110-462: The wet phase ushered in an expanding rainforest and wooded savanna from Senegal to Cameroon . Between 9,000 and 5,000 BC, Niger–Congo speakers domesticated the oil palm and raffia palm . Black-eyed peas and voandzeia (African groundnuts), were domesticated, followed by okra and kola nuts . Since most of the plants grew in the forest, the Niger–Congo speakers invented polished stone axes for clearing forest. Around 4,000 BC,
31293-414: The whole continent, little of its surface falling below 1,500 m (4,900 ft), while the summits reach heights of 4400 m to 4550 m. This block of country lies just west of the line of the great East African Trough, the northern continuation of which passes along its eastern escarpment as it runs up to join the Red Sea. There is, however, in the centre a circular basin occupied by Lake Tsana . Both in
31476-413: The world's second-largest and second-most populous continent after Asia . At about 30.3 million km (11.7 million square miles) including adjacent islands, it covers 20% of Earth 's land area and 6% of its total surface area. With nearly 1.4 billion people as of 2021, it accounts for about 18% of the world's human population . Africa's population is the youngest among all the continents;
31659-418: Was rapidly conquered and colonised by European nations , save for Ethiopia and Liberia . European rule had significant impacts on Africa's societies , and colonies were maintained for the purpose of economic exploitation and extraction of natural resources. Most present states emerged from a process of decolonisation following World War II , and established the Organisation of African Unity in 1963,
31842-504: Was carrying 100,000 passengers each year., but as of 2014 she was out of service. She normally serves the southern part of the lake but if Ilala was out of service she operated the route to Karonga. The Tanzanian ferry MV Songea was built in 1988. Her operator was the Tanzania Railway Corporation Marine Division until 1997, when it became the Marine Services Company Limited . Songea plies weekly between Liuli and Nkhata Bay via Itungi and Mbamba Bay . The worst Lake disaster

The Kingdom of Ife , historically the first of these Yoruba city-states or kingdoms, established government under a priestly oba ('king' or 'ruler' in the Yoruba language ), called the Ooni of Ife . Ife
32208-468: Was expected to be complete during the first half of 2014, but was halted in 2017. MV Mpasa entered service in 1935. The ferry MV Ilala entered service in 1951. In recent years she has often been out of service, but when operational she runs between Monkey Bay at the southern end of the lake to Karonga on the northern end, and occasionally to the Iringa Region of Tanzania. The ferry MV Mtendere entered service in 1980. By 1982 she
32391-450: Was fully established by roughly 500 BC in many areas of East and West Africa, although other regions did not begin ironworking until the early centuries AD. Copper objects from Egypt , North Africa, Nubia, and Ethiopia dating from around 500 BC have been excavated in West Africa, suggesting that Trans-Saharan trade networks had been established by this date. From 3500 BC, nomes (ruled by nomarchs ) coalesced to form
32574-474: Was independently invented in the region of Mali in the savannah of West Africa. In the steppes and savannahs of the Sahara and Sahel in Northern West Africa, people possibly ancestral to modern Nilo-Saharan and Mandé cultures started to collect wild millet , around 8,000 to 6,000 BC. Later, gourds , watermelons , castor beans , and cotton were also collected. Sorghum was first domesticated in Eastern Sudan around 4,000 BC, in one of
32757-444: Was noted as a major religious and cultural centre in West Africa and for its unique naturalistic tradition of bronze sculpture. The Ife model of government was adapted by the Oyo Empire , whose obas, called the Alaafins of Oyo , controlled many other Yoruba and non-Yoruba city-states and kingdoms including the Fon Kingdom of Dahomey . The Almoravids were a Berber dynasty from the Sahara that spread over northwestern Africa and
32940-514: Was one of the first African countries to gain independence, the state remained under the control of the country's white minority, initially through qualified voting rights and from 1956 by a system of racial segregation known as apartheid , until 1994. Today, Africa contains 54 sovereign countries. Since independence, African states have frequently been hampered by instability, corruption, violence, and authoritarianism. The vast majority of African states are republics that operate under some form of
33123-1169: Was revealed that approximately 50 litres of non radioactive material leaked into a local creek. Despite reports in local media of radioactive contamination the government conducted independent scientific tests on the local river system and found that there was no effect on the environment. The 25 km solo swim across Lake Malawi between Cape Ngomba and Senga Bay has been accomplished on 5 occasions by 16 swimmers 1992: Lewis Pugh 9hrs 52 minutes (UK/South Africa) and Otto Thanning (South Africa) 10hrs 5 minutes 2010: Abigail Brown (UK) 9hrs 45 minutes 2013: Milko van Gool (Netherlands) 8hrs 46 minutes and Kaitlin Harthoorn (US) 9hrs 17 minutes 2016: (current record) Jean Craven (South Africa), Robert Dunford (Kenya), Michiel Le Roux (South Africa), Samantha Whelpton (South Africa), Greig Bannatyne (South Africa), Haydn Von Maltitz (South Africa), Douglas Livingstone-Blevins (South Africa) 7hrs 53 mins 2019: Chris Stapley ( Eswatini ) and Jay Azran (South Africa) 8hrs 40 minutes, Andrew Stevens ( Australia ) 10hrs 50 minutes, and Ruth Azran (South Africa) 11hrs 8 minutes. That same year, Martin Hobbs (South Africa), became
33306-410: Was the first European to visit the lake in 1846. David Livingstone reached the lake in 1859, and named it Lake Nyasa. He also referred to it by a pair of nicknames: Lake of Stars and Lake of Storms. The Lake of Stars nickname came after Livingstone observed lights from the lanterns of the fishermen in Malawi on their boats, that resemble, from a distance, stars in the sky. Later, after experiencing
33489-411: Was the sinking of the MV Vipya in 1946, which resulted in 145 deaths. Wildlife found in and around Lake Malawi or Nyasa includes Nile crocodiles , hippopotamus , monkeys , and a significant population of African fish eagles that feed off fish from the lake. Lake Malawi has for millennia provided a major food source to the residents of its shores since its waters are rich in fish. Among
