Science and technology in Africa
Encyclopedia
Science and technology in Africa has a history stretching to the beginning of the human species, stretching back to the first evidence of tool use
by hominid ancestors in the areas of Africa where humans are believed to have evolved.
Forty percent of African scientists live in OECD countries, predominantly western countries. This has been described as an African brain drain
.
Sub-Saharan African countries spent an average of just 0.3% of their GDP on S&T(Science and Technology) in 2007. This represent and increase from US$1.8bn in 2002 to US$2.8bn in 2007. North Africa
n countries spend 0.4% of GDP on S&T, an increase from US$2.6bn in 2002 to US$3.3bn in 2007. This represent an increase of 50% in spending in S&T in Africa. South Africa
is the sole exception. South Africa
spends 0.87% of GDP on S&T.
Although technology parks have a long history, first in the US and later in Europe and the rest of the
world, their presence in Africa is still limited, as Africa continues to lag behind other regions of the
world in terms of technological development and innovation. Only six countries (Morocco
, Egypt
, Senegal
, Madagascar
, Tunisia
and South Africa
) have initiated programmes of technology parks as an integral strategy of their sustainable development.
In recent years more African countries have embraced technology as a driver of development e.g. Kenya
's Vision 2030 and Rwanda
's rapid ICT growth. The growth especially in mobile telephony and ICT across sub-Saharan Africa has improved living standards greatly. Membership in social networking sites such as Facebook
and Tokea! has risen from a few hundreds to over 100,000.
of Africa, the first development of tools is found there as well:
was founded in Egypt. It was considered the largest library in the classical world.
Al-Azhar University
, founded in 970~972 as a madrasa, is the chief centre of Arabic literature and Sunni Islamic learning in the world. The oldest degree-granting university in Egypt after the Cairo University
, its establishment date may be considered 1961 when non-religious subjects were added to its curriculum.
.
By the end of Mansa Musa's reign, the Sankoré University had been converted into a fully staffed University with the largest collections of books in Africa since the Library of Alexandria
. The Sankoré University was capable of housing 25,000 students and had one of the largest libraries in the world with between 400,000 to 700,000 manuscripts.
Timbuktu
was a major center of book copying, with scholars visiting from throughout the Muslim world.
in Fes, Morocco is founded by the princess Fatima al-Fihri. It is recognized by the Guinness Book of World Records as the oldest academic degree-granting university in the world.

/ Big Dipper
which was known to Egyptians as the thigh. It is thought that a vertical alignment between these two stars checked with a plumb bob was used to ascertain where North lay. The deviations from true North using this model reflect the accepted dates of construction.
Egyptians were the first to develop a 365 day, 12 month calendar. It was a stellar calendar,created by observing the stars.
Some have argued that the pyramids were laid out as a map of the three stars in the belt of Orion, although this theory has been criticized by reputable astronomers.
During the 12th century, the astrolabic quadrant is invented in Egypt.
2. They had a helio-centric view of the solar system 3. Diagrams of planets and orbits made use of complex mathematical calculations 4. Developed algorithm that accurately orient Timbuktu to Mecc. 5. They recorded astronomical events, including a meteor shower in August 1583.
a group of megaliths, dated 300 BCE, was used by Cushitic speaking people as an alignment with star systems tuned to a lunar calendar of 354 days. This discovery was made by B.N. Lynch and L. H. Robins of Michigan State University.
Great Zimbabwe
could have been an astronomical observatory contends Richard Wade, of the Nkwe Ridge Observatory, South Africa after 30 years of researching the site. In southern Zimbabwe the shadow of the Moon appears between 0610 and 0620 near the site. Megaliths east of the Great Enclosure align with the Moon, the Sun, and stars during important astronomical events of the year. One Megaliths could be an eclipse predictor. The conical structure aligns with a supernova in the Vela, 700–800 years ago.
Three types of calendars can be found in Africa: 1. Lunar 2. Solar 3. Stellar. Most African calendar are a combination of the three.

South Africa
has cultivated a burgeoning astronomy community. It hosts the Southern African Large Telescope
, the largest optical telescope in the southern hemisphere. South Africa
is currently building the Karoo Array Telescope as a pathfinder for the $20 billion Square Kilometer Array project. South Africa
is a finalist, with Australia, to be the host of the SKA.
. It dates from 35,000 BCE and consists of 29 distinct notches that were deliberately cut into a baboon
's fibula.
The Ishango bone
is a bone tool
, dated to the Upper Paleolithic
era, about 18,000 to 20,000 BCE. It is a dark brown length of bone, the fibula of a baboon, with a sharp piece of quartz affixed to one end, perhaps for engraving or writing. It was first thought to be a tally stick
, as it has a series of tally marks
carved in three columns running the length of the tool, but some scientists have suggested that the groupings of notches indicate a mathematical understanding that goes beyond counting. These are the function postulated about the Ishango bones:
1. A tool for multiplication, division, and simple mathematical calculation 2. A six month lunar calendar 3. a construct of a woman, keeping track of her menstrual cycle
In the book How Mathematics Happened: The First 50,000 Years, Peter Rudman argues that the development of the concept of prime numbers could only have come about after the concept of division, which he dates to after 10,000 BC, with prime numbers probably not being understood until about 500 BC. He also writes that "no attempt has been made to explain why a tally of something should exhibit multiples of two, prime numbers between 10 and 20, and some numbers that are almost multiples of 10."
period, and show a fully developed numeral system
. The importance of mathematics to an educated Egyptian is suggested by a New Kingdom fictional letter in which the writer proposes a scholarly competition between himself and another scribe regarding everyday calculation tasks such as accounting of land, labor and grain. Texts such as the Rhind Mathematical Papyrus
and the Moscow Mathematical Papyrus
show that the ancient Egyptians could perform the four basic mathematical operations—addition, subtraction, multiplication, and division—use fractions, compute the volumes of boxes and pyramids, and calculate the surface areas of rectangles, triangles, circles and even spheres. They understood basic concepts of algebra
and geometry
, and could solve simple sets of simultaneous equations
.
Mathematical notation
was decimal, and based on hieroglyphic signs for each power of ten up to one million. Each of these could be written as many times as necessary to add up to the desired number; so to write the number eighty or eight hundred, the symbol for ten or one hundred was written eight times respectively. Because their methods of calculation could not handle most fractions with a numerator greater than one, ancient Egyptian fractions had to be written as the sum of several fractions. For example, the fraction two-fifths was resolved into the sum of one-third + one-fifteenth; this was facilitated by standard tables of values. Some common fractions, however, were written with a special glyph; the equivalent of the modern two-thirds is shown on the right.
Ancient Egyptian mathematicians had a grasp of the principles underlying the Pythagorean theorem
, knowing, for example, that a triangle had a right angle opposite the hypotenuse
when its sides were in a 3–4–5 ratio. They were able to estimate the area of a circle by subtracting one-ninth from its diameter and squaring the result:
a reasonable approximation of the formula π
r2.
The golden ratio
seems to be reflected in many Egyptian constructions, including the pyramids
, but its use may have been an unintended consequence of the ancient Egyptian practice of combining the use of knotted ropes with an intuitive sense of proportion and harmony.
Based on engraved plans of Meroitic King Amanikhabali's pyramids, Nubians had a sophisticated understanding of mathematics and an appreciation of the harmonic ratio. The engraved plans is indicative of much to be revealed about Nubian mathematics.
geometry. The knowledge of fractal
geometry can be found in a wide aspect of African life from art, social design structures, architecture, to devination systems. With the discovery of fractal mathematics in widespread use in Africa, Ron Eglash had this to say,
to the Iron Age
. The Iron Age
and Bronze Age
occurred simultaneously. North Africa
and the Nile Valley imported its iron technology from the Near East
and followed Near Eastern course of Bronze Age
and Iron Age
development.
Many Africanist accept an independent development of the use of iron in Sub-Saharan Africa. Among archaeologists, it is a debatable issue. The earliest dating of iron in Sub-Saharan Africa is 2500 BCE at Egaro, west of Termit, making it contemporary to the Middle East
. The Egaro date is debatable with archaeologists, due to the method used to attain it. The Termit date of 1500 BCE is widely accepted. Iron use, in smelting
and forging for tools, appears in West Africa by 1200 BCE, making it one of the first places for the birth of the Iron Age. Before the 19th century, African methods of extracting iron was employed in Brazil
, until more advanced Europe
an methods were instituted.
In Aïr Mountains
region of Niger
, copper smelting was independently developed between 3000–2500 BCE. The undeveloped nature of the process indicates that it was not of foreign origin. Smelting in the region became mature around 1500 BCE.
Around 500 BCE, Nubia, in her Meroitic phase
, became a major manufacturer and exporter of iron. This was after being expelled from Egypt by Assyrians, who used iron weapons.
The Aksumites produced coins
around 270 CE, under the rule of king Endubis. Aksumite coins were issued in gold, silver, and bronze.
routes. They provided 2/3 of the gold in Europe and North Africa. The Almoravid dinar and the Fatimid dinar were printed on gold from the Sahelian empires. The ducat of Genoa and Venice and the florine of Florence were also printed on gold from the Sahelian empires. When gold sources were depleted in the Sahel, the empires turned to trade with the Ashante Kingdom.
The Swahili traders in East Africa, were major suppliers of gold to Asia in the Red Sea and Indian Ocean trade routes. The trading port cities and city-states of the Swahili East African coast were among the first African cities to come into contact with European explorers and sailors during the European Age of Discovery
. Many were documented and praised in the recordings of North African explorer Abu Muhammad ibn Battuta
.
Anthropologist Peter Schmidt discovered through the communication of oral tradition that the Haya have been forging steel
for nearly 2000 years. This discovery was made accidentally while Schmidt was learning about the history of the Haya via their oral tradition. He was led to a tree which was said to rest on the spot of an ancestral furnace used to forge steel. When later tasked with the challenge of recreating the forges, a group of elders who at this time were the only ones to remember the practice, due to the disuse of the practice due in part to the abundance of steel flowing into the country from foreign sources. In spite of their lack of practice, the elders were able to create a furnace
using mud and grass which when burnt provided the carbon needed to transform the iron into steel. Later investigation of the area yielded 13 other furnaces similar in design to the recreation set up by the elders. These furnaces were carbon dated and were found to be as old as 2000 years, whereas steel of this caliber did not appear in Europe
until several centuries later.
Two types of iron furnaces were used in Sub-Saharan Africa: the trench dug below ground and circular clay structures built above ground. Iron ores were crushed and placed in furnaces layered with the right proportion of hardwood. A flux such as lime sometimes from seashells were added to aid in smelting. Bellows on the side would be used to add oxygen. Clay pipes on the sides called tuyéres would be used to control oxygen flow.
remarked that there was a high degree of specialization among Egyptian physicians, with some treating only the head or the stomach, while others were eye-doctors and dentists. Training of physicians took place at the Per Ankh or "House of Life" institution, most notably those headquartered in Per-Bastet
during the New Kingdom and at Abydos
and Saïs
in the Late period. Medical papyri
show empirical knowledge
of anatomy, injuries, and practical treatments. Wounds were treated by bandaging with raw meat, white linen, sutures, nets, pads and swabs soaked with honey to prevent infection, while opium was used to relieve pain. Garlic and onions were used regularly to promote good health and were thought to relieve asthma
symptoms. Ancient Egyptian surgeons stitched wounds, set broken bones
, and amputated diseased limbs, but they recognized that some injuries were so serious that they could only make the patient comfortable until he died.
Around 800, the first psychiatric hospital and insane asylum in Egypt is built by Muslim physicians in Cairo.
Around 1100, the ventilator is invented in Egypt.
In 1285, the largest hospital of the Middle Ages and pre-modern era is built in Cairo, Egypt, by Sultan Qalaun al-Mansur. Treatment was given for free to patients of all backgrounds, regardless of gender, ethnicity or income.
Tetracycline was being used by Nubians, based on bone remains between 350 AD and 550 AD. The antibiotic was in wide commercial use only in the mid 20th century. The theory is earthen jars containing grain used for making beer contained the bacteria streptomycedes, which produced tetracycline. Although Nubians were not aware of tetracycline, they could have notice people fared better by drinking beer. According to Charlie Bamforth, a professor of biochemistry and brewing science at the University of California, Davis, said "They must have consumed it because it was rather tastier than the grain from which it was derived. They would have noticed people fared better by consuming this product than they were just consuming the grain itself."
the mosquito was identified to be the cause of malaria, and the removal of cataracts was a common surgical procedure.
The dangers of tobacco smoking were known to African Muslim scholars, based on Timbuktu manuscripts.
European travelers in the Great Lakes region of Africa
(Uganda
and Rwanda
) during the 19th century observed Caeserean sections being performed on a regular basis. The expectant mother was normally anesthetized with banana wine, and herbal mixtures were used to encourage healing. From the well-developed nature of the procedures employed, European observers concluded that they had been employed for some time.
A South African, Max Theiler
, developed a vaccine against Yellow Fever in 1937.
The first human-to-human heart transplant was performed by South African cardiac surgeon Christiaan Barnard
at Groote Schuur Hospital
in December 1967.
During the 1960s, South African Aaron Klug
developed crystallographic electron microscopy techniques, in which a sequence of two-dimensional images of crystals taken from different angles are combined to produce three-dimensional images of the target.
South African, Allan McLeod Cormack
develop the theoretical underpinnings of CT scanning and co-invented the CT-scanner.
and Bir Kiseiba as far back as 9000 BP, making it the first location of domestication. Scholars are divided as to independent and earliest domestication of cattle.
Between 13,000 and 11,0000 BCE wild grains began to be collected as source of food in the cataract region of the nile, south of Egypt. The collecting of wild grains as source of food spread to Syria, parts of Turkey and Iran by the eleventh millennium BCE. By the tenth and ninth millennia southwest Asians domesticated their wild grains, wheat and barley after the notion of collecting wild grains was spread from the nile.
The donkey
was domesticated in the Red Sea Hill and the Horn of Africa
in 4000 BCE and spread to southwest Asia.
Ethiopians, particularly the Oromo people
, were the first to have discovered and recognized the energizing effect of the coffee
bean plant.
Cotton(Gossypium herbaceum Linnaeus) was domesticated 5000 BCE in eastern Sudan
near the Middle Nile Basin region, and cotton cloth was being produced.Teff
is believed to have originated in Ethiopia between 4000 and 1000 BCE. Genetic evidence points to E. pilosa as the most likely wild ancestor.Noog(Guizotia abyssinica) and ensete
(E. ventricosum) are two other plants domesticated in Ethiopia.
was developed independently from the Middle East
in the Sahel
.
The first instances of domestication of plants for agricultural purposes in Africa occurred in the Sahel
region c. 5000 BCE, when sorghum
and african rice
(Oryza glaberrima) began to be cultivated. Around this time, and in the same region, the small Guineafowl
was domesticated. Other African domesticated plants were oil palm, raffia palm
, black eyed peas, groundnuts, and kola nuts.African method of cultivating rice was used in North Carolina introduced by enslaved African. african rice cultivation was a factor in the prosperity of the North Carolina colony.
Yam
was domesticated 8000 BCE in West Africa. Between 7000 and 5000 BCE, pearl millet
, gourds, watermelons, and beans, and farming and herding practices were spread westward across the southern Sahara.
West Africans were probably the first people to start using the method of fish lines and hook in fishing. The hooks were made of bone , hard wood, or shell between 16,000 to 9000 BCE.
Between 6500 and 3500 BCE knowledge of domesticated sorghum, castor beans, and two species of gourd spread from Africa to Asia, later pearl millet, black eyed peas, watermellon and okra to the rest of the world.
Pottery was first made in the Sahel around 9000 to 8000 BCE, making it one of the earliest region of independent pottery development.
is a ruined settlement on the slopes of Mount Ngorongoro in northern Tanzania.
Seven stone terraced villages along the mountainside comprised the settlement. A complex
structure of stone channel irrigation was used to dike, dam, and level surrounding river
waters. The stone channels run along the mountainside and base. Some of these channels were
several kilometers long channelling and feeding individual plots of land. The irrigation channels fed a total area of 5000 acres (20.2 km²).
from the flax
plant, which were beaten and combed. The priest and pharaohs wore leopard skin. The ancient Egyptians used looms as early as 4000 BCE.
Nubians mainly wore cotton, beaded leather, and linen
. Nubia was also a center of cotton manufacturing. Cotton was domesticated 5000 BCE in eastern Sudan
near the Middle Nile Basin region, and cotton cloth was being produced.
Shemma, shama, and kuta are all cotton base cloth used for making Ethiopian
clothing.
is cotton. It is widely used in making the boubou
(male) and kaftan
(female), a style of West African clothing.
Bògòlanfini

By the 12th century, so-called Moroccan leather, which actually came from the Hausa
area of northern Nigeria
, was supplied to Mediterranean markets and found their way to the fairs and markets of such places as Normandy and Britain.
, kente cloth
, raffia cloth, barkcloth
, kanga
, kitenge
, and lamba mpanjaka. The Djellaba
was made typically of wool and worn in the Maghreb. Kente used silk from the Anaphe moth and was produced by the Akan people
(Ashante, Fante, Enzema) in the countries of Ghana
and Ivory Coast. Raffia cloth was the innovation of the Kuba
people, present day Democratic Republic of Congo. It used the fibers of the leaves on the raffia palm
tree. Barkcloth
was used by the Baganda
in Uganda
from the Mutuba tree (Ficus natalensis). Kanga
are Swahili
cloth that comes in rectangular shapes, made of pure cotton, and put together to make clothing. It is as long as ones outstretch hand and wide to cover the length of ones neck. Kitenges are similar to kangas and kikoy, but are of a thicker cloth, and have an edging only on a long side. Kenya
, Uganda
, Tanzania
, and Sudan
are some of the African countries where kitenge is worn. In Malawi
, Namibia
and Zambia
, kitenge is known as Chitenge. Lamba Mpanjaka was cloth made of multicolored silk, worn like a toga on the island of Madagascar.
Camel hair
was also used to make cloth in the Sahel
and North Africa
.
In Southern Africa one finds numerous use of animal hide and skins for clothing. The Ndau in central Mozambique and the Shona mixed hide with barkcloth, cotton cloth. Cotton weaving was practiced by the Ndau and Shona. Cotton cloth was referred to as machira. The Venda, Swazi, Basotho, Zulu, Ndebele], and Xhosa also made extensive use of hides. Hides came from cattle, sheep, goat, elephant, and from jangwa( part of the mongoose family). Leopard skins were coveted and was a symbol of kingship in Zulu society. Skins were tanned to form leather, dyed, and embedded with beads.
Three types of loom
s are used in Africa: 1. the double heddle loom for narrow strips of cloth, 2. the single heddle loom for wider spans of cloth 3. the ground or pit loom. The double heddle loom and single heddle loom might be of indigenous origin. The ground or pit loom is used in the Horn of Africa
, Madagascar
, and North Africa
and is of Middle Eastern origins.
by fulani herdsmen, near the Yobe river, in the village of Dufuna. It was dated 8000 years, cut out of African mahogany. Based on "stylistic sophistication", the tradition of canoe building must have gone further back in time, noted one archaeologist.
knew how to assemble planks
of wood into a ship hull as early as 3000 BC. The Archaeological Institute of America
reports that the oldest ships yet unearthed, a group of 14 discovered in Abydos
, were constructed of wooden planks which were "sewn" together. Discovered by Egyptologist David O'Connor of New York University
. woven strap
s were found to have been used to lash the planks together, and reeds
or grass
stuffed between the planks helped to seal the seams. Because the ships are all buried together and near a mortuary belonging to Pharaoh Khasekhemwy
, originally they were all thought to have belonged to him, but one of the 14 ships dates to 3000 BC, and the associated pottery jars buried with the vesse The ship dating to 3000 BC was 75 feet (22.9 m) long and is now thought to perhaps have belonged to an earlier pharaoh. Professor O'Connor, the 5,000-year-old ship may have even belonged to Pharaoh Aha
.
Early Egyptians also knew how to assemble planks of wood with treenail
s to fasten them together, using pitch
for caulking
the seams
. The "Khufu ship
", a 43.6-meter vessel sealed into a pit in the Giza pyramid complex
at the foot of the Great Pyramid of Giza
in the Fourth Dynasty
around 2500 BCE, is a full-size surviving example which may have fulfilled the symbolic function of a solar barque. Early Egyptians also knew how to fasten the planks of this ship together with mortise and tenon
joints.
It is known that ancient Axum
traded with India
, and there is evidence that ships from Northeast Africa may have sailed back and forth between India/Sri Lanka and Nubia trading goods and even to Persia, Himyar and Rome
. Aksum was known by the Greeks
for having seaports for ships from Greece and Yemen
. Elsewhere in Northeast Africa, the Periplus of the Red Sea
reports that Somalis
, through their northern ports such as Zeila
and Berbera
, were trading frankincense
and other items with the inhabitants of the Arabian Peninsula
well before the arrival of Islam
as well as with then Roman
-controlled Egypt
.
of the Mali Empire
is thought to have had a great armada of ships sitting on the coast of West Africa
. This is corroborated by ibn Battuta himself who recalls several hundred Malian ships off the coast. The ships would communicate with each other by drums. This has led to great speculation, that Malian sailors may have reached the coast of Pre-Columbian
America under the rule of Abubakari II, nearly two hundred years before Christopher Columbus.
Numerous sources attest that the inland waterways of West Africa saw extensive use of war-canoes and vessels used for war transport where permitted by the environment. Most West African canoes were of single log construction, carved and dug-out from one massive tree trunk. The primary method of propulsion was by paddle and in shallow water, poles. Sails were also used to a lesser extent, particularly on trading vessels. The silk cotton tree provided many of thesui most table logs for massive canoe building, and launching was via wooden rollers to the water. Boat building specialists were to emerge among certain tribes, particularly in the Niger Delta.
Some canoes were 80 feet (24.4 m) in length, carrying 100 men or more. Documents from 1506 for example, refer to war-canoes on the Sierra Leone river, carrying 120 men. Others refer to Guinea coast peoples using canoes of varying sizes – some 70 feet (21.3 m) in length, 7–8 ft broad, with sharp pointed ends, rowing benches on the side, and quarter decks or focastles build of reeds, and miscellaneous facilities such as cooking hearths, and storage spaces for crew sleeping mats.
's fleet included large numbers of quadriremes and quinqueremes, warships with four and five ranks of rowers. Its ships dominated the Mediterranean. The Romans however were masters at copying and adapting the technology of other peoples. According to Polybius, the Romans seized a shipwrecked Carthaginian warship, and used it as a blueprint for a massive naval build-up, adding their own refinement - the corvus – which allowed an enemy vessel to be "gripped" and boarded for hand-to-hand fighting. This negated initially superior Carthaginian seamanship and ships.
Middle Age Swahili kingdoms
are known to have had trade port islands and trade routes with the Islamic world and Asia and were described by Greek historians are "metropolises". Famous African trade ports such as Mombasa
, Zanzibar
, Mogadishu
and Kilwa
were known to Chinese sailors such as Zheng He
and medieval Islamic historians such as the Berber Islamic voyager Abu Abdullah ibn Battuta
. The dhow
was the ship of trade used by the Swahili. They could be massive. It was a dhow that transported a giraffe to Chinese Emperor Yong Le's court, in 1414. Although the dhow is often associated with Arabs, it is of Indian roots.
The Great Pyramid
was the tallest man-made structure in the world for over 3,800 years.
The earliest style of Nubian architecture
included the speos, structures carved out of solid rock, an A-Group
(3700–3250 BCE) achievement. Egyptians made extensive use of the process at Speos Artemidos
and Abu Simbel
.
Sudan

is the oldest surviving archaeological settlements in West Africa
and the oldest all-stone settlement south of the Sahara. It is thought to have been built by Soninke people and is thought to be the precursor of the Ghana empire
.
Adobe, mudbrick
, and earth were the medium of West African and Sahelian architecture. Some notable structures are as follows:
The Great Mosque of Djenné
is the largest mud brick or adobe building in the world and is considered by many architects to be the greatest achievement of the Sudano-Sahelian architectural style, albeit with definite Islamic influences.
The Walls of Benin
City are collectively the world's largest man-made structure and were semi-destroyed by the British in 1897. Fred Pearce wrote in New scientist:
Sungbo's Eredo
is the second largest pre-colonial monument in Africa, larger than the Great Pyramids or Great Zimbabwe
. Built by the Yoruba people
in honour of one of their titled personages, an aristocratic widow known as the Oloye Bilikisu Sungbo, it is made up of sprawling mud walls and the valleys that surrounded the town of Ijebu-Ode in Ogun state, Nigeria.
Around 1000 AD, cob (tabya) first appears in the Maghreb and al-Andalus.
In Southern Africa one finds ancient and widespread traditions of building in stone. Two broad categories of these traditions have been noted: 1. Zimbabwean style 2. Transvaal Free State style. North of the Zambezi one finds very little stone ruins.Great Zimbabwe
, Khami
, Thulamela uses the Zimbabwean style. Tsotho/Tswana architecture represents the Transvaal Free State style. ||Khauxa!nas stone settlement in Namibia represents both traditions. The Kingdom of Mapungubwe (1075–1220) was a pre-colonial Southern African state located at the confluence of the Shashe and Limpopo rivers which marked the center of a pre-Shona kingdom which preceded the culmination of southeast African urban civilization in Great Zimbabwe
.
. Two scripts have been the direct offspring of Egyptian hieroglyphs
, the Proto-Sinaitic script and the Meroitic alphabet. Out of Proto-Sinaitic came the South Arabian alphabet
and Phoenician alphabet
, out of which the Aramaic alphabet
, Greek alphabet
, the Brāhmī script
, Arabic alphabet
were directly or indirectly derived.
Out of the South Arabian alphabet
came the Ge'ez alphabet
which is used to write Blin
(cushitic), Amharic, Tigre
, and Tigrinya in Ethiopia
and Eritrea
.
Out the Phoenician Alphabet
came tifinagh
, the berber alphabet mainly used by the Tuaregs.
The other direct offspring of Egyptian hieroglyphs
was the Meroitic alphabet. It began in the Napatan phase of Nubian history, Kush
(700–300 BCE). It came into full fruition in the 2nd century, under the successor Nubian kingdom of Meroë
. The script can be read but not understood, with the discovery at el-Hassa, Sudan of ram statues bearing meroitic inscriptions might assist in its translation.
in the Sahel
. Arabic writing is widespread in the Sahel
. The Arabic script was also used to write native African languages called Ajami. The Ajami languages include Hausa
, Mandinka
, Fulani, Wolofal
, Tamazight, Nubian
, Yoruba
, Songhai
, and Kanuri
. In East Africa Swahili
and Somali
were also written in Arabic script. So too was the Malagasy language
in Madagascar.

Niger-Congo Languages are tonal in nature. Talking drums exploit the tonal aspect of Niger-Congo languages to convey very complicated messages. Talking drums can send messages 15 to 25 miles (40.2 km). Bulu, a bantu language, can be drummed as well as spoken. In a Bulu village, each individual had a unique drum signature. A message could be sent to an individual by drumming his drum signature. It has been noted that a message can be sent 100 miles (160.9 km) from village to village within two hours or less using a talking drum.
Griots are repositories of African history, especially in African societies with no written language. Griots can recite genealogies going back centuries. They recite epics that reveal historical occurrences and events. Griots can go for hours and even days reciting the histories and genealogies of societies. They have been described as living history books.
Adamorobe Sign Language
is an indigenous sign language developed in the Adamorobe Akan
village in Eastern Ghana
. The village has a high incident of genetic deafness.
In 1260, the first portable hand cannons (midfa) loaded with explosive gunpowder, the first example of a handgun and portable firearm, were used by the Egyptians to repel the Mongols at the Battle of Ain Jalut
. The cannons had an explosive gunpowder composition almost identical to the ideal compositions for modern explosive gunpowder. They were also the first to use dissolved talc for fire protection, and they wore fireproof clothing, to which Gunpowder cartridges were attached.
Aksumite weapons were mainly made of iron: iron spears, iron swords, and iron knives called poniards. Shields were made of buffalo hide. In the latter part of the 19th century, Ethiopia made a concerted effort to modernize her army. She acquired repeating rifles, artillery, and machine guns. This modernization facilitated the Ethiopian victory over the Italians at the Tigray town of Adwa in the 1896
Battle of Adwa. Ethiopia was one of the few African countries to use artillery in colonial wars.
quilted cotton packed with kapok fiber and copper face plate. The stirrups could be used as weapon to disembowel enemy infantry or mounted soldiers at close range. Weapons included the sword, lance, battle-axe, and broad-bladed spear. The infantry were armed with bow and iron tipped arrows. Iron tips were usually laced with poison, from the West African plant Strophantus hispidus. Quivers of 40–50 arrows would be carried into battle. Later, muskets were introduced.
in 1274, according to 14th-century historian Ibn Khaldun
.
Most of tropical Africa
did not have a cavalry. Horses would be wiped out by tse-tse fly. The zebra
was never domesticated. The army of tropical Africa
consisted of mainly infantry. Weapons included bows and arrows with low bow strength that compensated with poison tipped arrows. Throwing knives were made use of in central Africa, spears that could double as thrusting cutting weapons, and swords were also in use. Heavy clubs when thrown could break bones,battle axe, and shields of various sizes were in widespread use. Later guns, muskets such as flintlock, wheelock, and matchlock. Against popular perception guns were in widespread use in Africa. They typically were of poor quality, a policy of European nations to provide poor quality merchandise. One reason the slave trade was so successful was the widespread use of guns in Africa.
Fortification was a major part of defense, integral to warfare. Massive earthworks were built around cities and settlements in West Africa, typically defended by soldiers with bow and poison tipped arrows. The earthworks are some of the largest man made structures in Africa and the world such as the wall of Benin and Sungbo's Eredo
. In Central Africa, the Angola region, one find preference for ditches, which were more successful for defense against wars with Europeans.
African infantry did not just include men. The state of Dahomey included all female units, who were personal body guards of the king. The Queen Mother of Benin had her own personal army,'Queens Own'.

From the 1960s to the 1980s, South Africa
pursued research into weapons of mass destruction
, including nuclear
, biological, and chemical weapons. Six nuclear weapons were assembled. With the anticipated changeover to a majority-elected government in the 1990s, the South African government dismantled all of its nuclear weapons, the first nation in the world which voluntarily gave up nuclear arms it had developed itself.
imported ivory, gold, incense, hardwood, and ostrich feather.
Nubia
exported gold, cotton/cotton cloth, ostrich feathers, leopard skins, ivory, ebony, and iron/iron weapons.
Aksum exported ivory, glass crystal, brass, copper, myrrh, and frinkincense. She imported silver, gold, olive oil, and wine.
The Aksumites produced coins around 270 CE, under the rule of king Endubis. Aksumite coins were issued in gold, silver, and bronze.
, Mali Empire
, and Songhay Empire were major exporters of gold, iron, tin, slaves, spears, javelin, arrows, bows, whips of hippo hide. They imported salt, horses, wheat, raisins, cowries, dates, copper, henna, olives, tanned hides, silk, cloth, brocade, Venetian pearls, mirrors, and tobacco.
Some of the currencies used in the Sahel are as follows:
1. Paper debt or IOU's were used for long distance trade.
2. Gold coins were also in use.
3. The mitkal(gold dust) currency was in use. It was gold dust that weighed 4.6 grams equivalent to 500 or 3,000 cowries.
4. Square cloth, four spans on each side, called chigguiya was used around the Senegal River.
In Kanem
cloth was the major currency. A cloth currency called dandi was in widespread use.
imported gold, copper, ivory, and slaves from tropical Africa. Carthage exported salt, cloth, metal goods.
Before camels were used in the trans-saharan trade pack animals, ox, donkeys, mules, and horses were utilized. Extensive use of camels began in the 1st century CE. Carthage minted gold, silver, bronze, and electrum
(mix gold and silver) coins mainly for fighting wars with Greeks and Romans. Most of their fighting force were mercenaries, who had to be paid.
Islamic North Africa made use of the Almoravid dinar
and Fatimid
dinar
, gold coins. The Almoravid dinar and the Fatimid
dinar were printed on gold from the Sahelian empires. The ducat
of Genoa and Venice and the florine of Florence were also printed on gold from the Sahelian empires.
The Swahilis served as middlemen. They connected African goods to Asian markets and Asian goods to African markets. Their most in demand export was Ivory. They exported ambergis, gold, leopard skins, slave, and tortoise shell. They imported from Asia oriental pottery and glassware. They also manufactured items such as cotton, glass and shell beads. Imports and locally manufactured goods were used as trade to acquire African goods. Trade links included the Arabian Peninsula, Persia, India, and China. The Swahili also
minted silver and copper coins.
Numerous metal objects and other items were used as currency in Africa. They are as follows: cowrie shells, salt, gold(dust or solid), copper, ingots, iron chains, tips of iron spears, iron knives, cloth in various shapes(square, rolled)etc. Copper
was as valuable as gold in Africa. Copper was not as widespread and more difficult to acquire, except in Central Africa, than gold. Other valuable metals included lead and tin. Salt
was also as valuable as gold. Because of its scarcity, it was used as currency.
The use of cowries as currency in West Africa has been since the 11 century when it was first recorded near Old Ghana. Its use has been much older. Sijilmasa
in present day Morocco seems to be a major source of cowries in the trans-saharan trade. In western Africa, shell money was usual tender up until the middle of the 19th century. Before the abolition of the slave trade there were large shipments of cowry shells to some of the English ports for reshipment to the slave coast. It was also common in West Central Africa as the currency of the Kingdom of Kongo called locally nzimbu. As the value of the cowry was much greater in West Africa than in the regions from which the supply was obtained, the trade was extremely lucrative. In some cases the gains are said to have been 500%. The use of the cowry currency gradually spread inland in Africa. By about 1850 Heinrich Barth found it fairly widespread in Kano, Kuka, Gando, and even Timbuktu. Barth relates that in Muniyoma, one of the ancient divisions of Bornu, the king's revenue was estimated at 30,000,000 shells, with every adult male being required to pay annually 1000 shells for himself, 1000 for every pack-ox, and 2000 for every slave in his possession. In the countries on the coast, the shells were fastened together in strings of 40 or 100 each, so that fifty or twenty strings represented a dollar; but in the interior they were laboriously counted one by one, or, if the trader were expert, five by five. The districts mentioned above received their supply of kurdi, as they were called, from the west coast; but the regions to the north of Unyamwezi, where they were in use under the name of simbi, were dependent on Muslem traders from Zanzibar. The shells were used in the remoter parts of Africa until the early 20th century, but gave way to modern currencies. The shell of the land snail, Achatina monetaria, cut into circles with an open center was also used as coin in Benguella, Portuguese West Africa.
In 953, the earliest historical record of a reservoir pen dates back to 953, when Ma'ad al-Mu'izz, the caliph of Egypt, demanded a pen which would not stain his hands or clothes, and was provided with a pen which held ink in a reservoir and delivered it to the nib, as recorded by Qadi al-Nu'man al-Tamimi (d. 974) in his Kitdb al-Majalis wa'l-musayardt.

In the book How Mathematics Happened: The First 50,000 Years, Peter Rudman argues that the development of the concept of prime numbers could only have come about after the concept of division, which he dates to after 10,000 BC, with prime numbers probably not being understood until about 500 BC. He also writes that "no attempt has been made to explain why a tally of something should exhibit multiples of two, prime numbers between 10 and 20, and some numbers that are almost multiples of 10."

was decimal, and based on hieroglyphic signs for each power of ten up to one million. Each of these could be written as many times as necessary to add up to the desired number; so to write the number eighty or eight hundred, the symbol for ten or one hundred was written eight times respectively. Because their methods of calculation could not handle most fractions with a numerator greater than one, ancient Egyptian fractions had to be written as the sum of several fractions. For example, the fraction two-fifths was resolved into the sum of one-third + one-fifteenth; this was facilitated by standard tables of values. Some common fractions, however, were written with a special glyph; the equivalent of the modern two-thirds is shown on the right.

geometry can be found in a wide aspect of African life from art, social design structures, architecture, to devination systems. With the discovery of fractal mathematics in widespread use in Africa, Ron Eglash had this to say,
-
- "We used to think of mathematics as a kind of ladder that you climb, and we would think of counting systems – one plus one equals two – as the first step and simple shapes as the second step. Recent mathematical developments like fractal geometry represented the top of the ladder in most Western thinking. But it's much more useful to think about the development of mathematics as a kind of branching structure and that what blossomed very late on European branches might have bloomed much earlier on the limbs of others. When Europeans first came to Africa, they considered the architecture very disorganized and thus primitive. It never occurred to them that the Africans might have been using a form of mathematics that they hadn't even discovered yet."

for nearly 2000 years. This discovery was made accidentally while Schmidt was learning about the history of the Haya via their oral tradition. He was led to a tree which was said to rest on the spot of an ancestral furnace used to forge steel. When later tasked with the challenge of recreating the forges, a group of elders who at this time were the only ones to remember the practice, due to the disuse of the practice due in part to the abundance of steel flowing into the country from foreign sources. In spite of their lack of practice, the elders were able to create a furnace

using mud and grass which when burnt provided the carbon needed to transform the iron into steel. Later investigation of the area yielded 13 other furnaces similar in design to the recreation set up by the elders.

Two types of iron furnaces were used in Sub-Saharan Africa: the trench dug below ground and circular clay structures built above ground. Iron ores were crushed and placed in furnaces layered with the right proportion of hardwood. A flux such as lime sometimes from seashells were added to aid in smelting. Bellows on the side would be used to add oxygen. Clay pipes on the sides called tuyéres would be used to control oxygen flow.

Tetracycline was being used by Nubians, based on bone remains between 350 AD and 550 AD. The antibiotic was in wide commercial use only in the mid 20th century. The theory is earthen jars containing grain used for making beer contained the bacteria streptomycedes, which produced tetracycline. Although Nubians were not aware of tetracycline, they could have notice people fared better by drinking beer. According to Charlie Bamforth, a professor of biochemistry and brewing science at the University of California, Davis, said "They must have consumed it because it was rather tastier than the grain from which it was derived. They would have noticed people fared better by consuming this product than they were just consuming the grain itself."

Numerous sources attest that the inland waterways of West Africa saw extensive use of war-canoes and vessels used for war transport where permitted by the environment. Most West African canoes were of single log construction, carved and dug-out from one massive tree trunk. The primary method of propulsion was by paddle and in shallow water, poles. Sails were also used to a lesser extent, particularly on trading vessels. The silk cotton tree provided many of thesui most table logs for massive canoe building, and launching was via wooden rollers to the water. Boat building specialists were to emerge among certain tribes, particularly in the Niger Delta.
Some canoes were 80 feet (24.4 m) in length, carrying 100 men or more. Documents from 1506 for example, refer to war-canoes on the Sierra Leone river, carrying 120 men. Others refer to Guinea coast peoples using canoes of varying sizes – some 70 feet (21.3 m) in length, 7–8 ft broad, with sharp pointed ends, rowing benches on the side, and quarter decks or focastles build of reeds, and miscellaneous facilities such as cooking hearths, and storage spaces for crew sleeping mats.

's fleet included large numbers of quadriremes and quinqueremes, warships with four and five ranks of rowers. Its ships dominated the Mediterranean. The Romans however were masters at copying and adapting the technology of other peoples. According to Polybius, the Romans seized a shipwrecked Carthaginian warship, and used it as a blueprint for a massive naval build-up, adding their own refinement - the corvus – which allowed an enemy vessel to be "gripped" and boarded for hand-to-hand fighting. This negated initially superior Carthaginian seamanship and ships.

Other African traditions
One common theme in much traditional African architecture is the use of fractal scaling: small parts of the structure tend to look similar to larger parts, such as a circular village made of circular houses.Around 1000 AD, cob (tabya) first appears in the Maghreb and al-Andalus.

Ancient Egyptian weaponry include bows and arrow, maces, clubs, swords, scimitars, battle axe, spears, shields, and scabbard. Body armor was made of bands of leathers and sometimes laid with scales and sleeves. Horse drawn chariots were used to deliver archers into the battle field. Weapons would be made initially with stone, wood, and copper, later bronze, and later iron.In 1260, the first portable hand cannons (midfa) loaded with explosive gunpowder, the first example of a handgun and portable firearm, were used by the Egyptians to repel the Mongols at the Battle of Ain Jalut

. The cannons had an explosive gunpowder composition almost identical to the ideal compositions for modern explosive gunpowder. They were also the first to use dissolved talc for fire protection, and they wore fireproof clothing, to which Gunpowder cartridges were attached.
Aksumite weapons were mainly made of iron: iron spears, iron swords, and iron knives called poniards. Shields were made of buffalo hide. In the latter part of the 19th century, Ethiopia made a concerted effort to modernize her army. She acquired repeating rifles, artillery, and machine guns. This modernization facilitated the Ethiopian victory over the Italians at the Tigray town of Adwa in the 1896
Battle of Adwa. Ethiopia was one of the few African countries to use artillery in colonial wars.
Sahelian
The Sahelian military consisted of cavalry and infantry. Cavalry consisted of shielded, mounted soldiers. Body armor was chain mail or heavy quilted cotton. Helmets were made of leather, elephant, or hippo hide. Imported horses were shielded. Horse armor consisted ofquilted cotton packed with kapok fiber and copper face plate. The stirrups could be used as weapon to disembowel enemy infantry or mounted soldiers at close range. Weapons included the sword, lance, battle-axe, and broad-bladed spear. The infantry were armed with bow and iron tipped arrows. Iron tips were usually laced with poison, from the West African plant Strophantus hispidus. Quivers of 40–50 arrows would be carried into battle. Later, muskets were introduced.

consisted of mainly infantry. Weapons included bows and arrows with low bow strength that compensated with poison tipped arrows. Throwing knives were made use of in central Africa, spears that could double as thrusting cutting weapons, and swords were also in use. Heavy clubs when thrown could break bones,battle axe, and shields of various sizes were in widespread use. Later guns, muskets such as flintlock, wheelock, and matchlock. Against popular perception guns were in widespread use in Africa. They typically were of poor quality, a policy of European nations to provide poor quality merchandise. One reason the slave trade was so successful was the widespread use of guns in Africa.
Fortification was a major part of defense, integral to warfare. Massive earthworks were built around cities and settlements in West Africa, typically defended by soldiers with bow and poison tipped arrows. The earthworks are some of the largest man made structures in Africa and the world such as the wall of Benin and Sungbo's Eredo

in present day Morocco seems to be a major source of cowries in the trans-saharan trade. In western Africa, shell money was usual tender up until the middle of the 19th century. Before the abolition of the slave trade there were large shipments of cowry shells to some of the English ports for reshipment to the slave coast. It was also common in West Central Africa as the currency of the Kingdom of Kongo called locally nzimbu. As the value of the cowry was much greater in West Africa than in the regions from which the supply was obtained, the trade was extremely lucrative. In some cases the gains are said to have been 500%. The use of the cowry currency gradually spread inland in Africa. By about 1850 Heinrich Barth found it fairly widespread in Kano, Kuka, Gando, and even Timbuktu. Barth relates that in Muniyoma, one of the ancient divisions of Bornu, the king's revenue was estimated at 30,000,000 shells, with every adult male being required to pay annually 1000 shells for himself, 1000 for every pack-ox, and 2000 for every slave in his possession. In the countries on the coast, the shells were fastened together in strings of 40 or 100 each, so that fifty or twenty strings represented a dollar; but in the interior they were laboriously counted one by one, or, if the trader were expert, five by five. The districts mentioned above received their supply of kurdi, as they were called, from the west coast; but the regions to the north of Unyamwezi, where they were in use under the name of simbi, were dependent on Muslem traders from Zanzibar. The shells were used in the remoter parts of Africa until the early 20th century, but gave way to modern currencies.
