Tanning , or hide tanning , is the process of treating skins and hides of animals to produce leather . A tannery is the place where the skins are processed.
116-648: Kouroukan Fouga , or Kurukan Fuga , was the constitution of the Mali Empire created after the Battle of Krina (1235) by an assembly of nobles to create a government for the newly established empire, according to the Epic of Sundiata . According to oral tradition of the jelis of Mali and Guinea, the Kouroukan Fouga established the federation of Mandinka clans under one government, outlined how it would operate and established
232-441: A bath solution containing vegetable tannins, such as found in gallnuts , the leaves of sumac , the leaves of certain acacia trees, the outer green shells of walnuts , among other plants. The use of vegetable tanning is a process that takes longer than mineral tanning when converting rawhides into leather. Mineral tanned leather is used principally for shoes, car seats, and upholstery in homes (sofas, etc.). Vegetable tanned leather
348-577: A century later. Arab interest in the Mali Empire declined after the Songhai conquered the northern regions of the empire which formed the primary contact between Mali and the Arab world. For the later period of the Mali Empire, the major written primary sources are Portuguese accounts of the coastal provinces of Mali and neighboring societies. Mali , Mandé , Manden , and Manding are all various pronunciations of
464-493: A city on what is now the border between Guinea and Mali, was the capital for most of the empire's history, and this notion has taken hold in the popular imagination. Djibril Tamsir Niane , a Guinean historian, has been a forceful advocate of this position in recent decades. The identification of Niani as imperial capital is rooted in an (possibly erroneous) interpretation of the Arab traveler al Umari's work, as well as some oral histories. Extensive archaeological digs have shown that

An attempt to "reconstruct" the Kouroukan Fouga from oral tradition was made in 1998, in a regional workshop held in Kankan , Guinea , with the aim of publishing and preserving the oral history related to the area's djeli or griots. Assisted by modern communicators and Guinea linguists under the supervision of Siriman Kouyaté, the workshop transcribed and translated the laws and edicts preserved in different regions from

Collagen's high content of hydroxyproline allows cross-linking by hydrogen bonding within the helical structure. Ionized carboxyl groups (RCO 2 ) are formed by the action of hydroxide. This conversion occurs during the liming process, before introduction of
812-446: A lack of archaeological evidence of significant trade activity, clearly described by Arab visitors, particularly during the 14th century, Mali's golden age. In fact, there is a conspicuous absence of archaeological samples of any kind from Niani dated to the late 13th through early 15th centuries, suggesting that Niani may have been uninhabited during the heyday of the Mali Empire. Various sources cite several other cities as capitals of
928-464: A lack of definitive archaeological evidence, and the diversity of oral traditions all contribute to this uncertainty. A particular challenge lies in interpreting early Arabic manuscripts, in which, without vowel markings and diacritics, foreign names can be read in numerous different ways (e.g. Biti, Buti, Yiti, Tati). Ibn Battuta and Leo Africanus both call the capital "Mali." Early European writers such as Maurice Delafosse believed that Niani ,
1044-480: A large factor in how hazardous wastewater results in contaminating the environment. This is especially prominent in small and medium-sized tanneries in developing countries. The UN Leather Working Group (LWG) "provides an environmental audit protocol, designed to assess the facilities of leather manufacturers," for "traceability, energy conservation, [and] responsible management of waste products." Untanned hides can be dried and made pliable by rubbing and stretching
1160-430: A salt solution. After the hair was loosened, the tanners scraped it off with a knife. Once the hair was removed, the tanners would " bate " (soften) the material by pounding dung into the skin, or soaking the skin in a solution of animal brains. Bating was a fermentative process that relied on enzymes produced by bacteria found in the dung. Among the kinds of dung commonly used were those of dogs or pigeons. Historically
1276-661: A series of short reigns, often ending in palace coups. While maintaining a firm grip in the south and west, and even expanding in some areas, imperial control of their northernmost provinces was slipping, as attested by the Mossi raids on Macina. In 1433–1434, the Empire lost control of Timbuktu to the Tuareg, led by Akil Ag-Amalwal. Three years later, Oualata also fell into their hands. The rising Songhai Empire conquered Mema , one of Mali's oldest possessions, in 1465. It then seized Timbuktu from

The kankoro-sigui held increasing influence as a power behind the throne. During this period the Jolof Empire was founded, and soon dominated all of northern Senegambia . In the 1370s a war between Mali imperial forces and Berber Tuareg forces from Takedda devastated
1624-442: A tanning agent. They are then soaked, stretched, dried, and sometimes smoked. Preparing hides begins by curing them with salt to prevent putrefaction of the collagen from bacterial growth during the time lag from procuring the hide to when it is processed. Curing removes water from the hides and skins using a difference in osmotic pressure. The moisture content of hides and skins is greatly reduced, and osmotic pressure increased, to

In contrast to negative formulations (e.g., “Thou shalt not” in the Hebrew Bible), Nesbitt indicates that the basis for
1972-474: Is also known through the account of Shihab al-'Umari , written in about 1340 by a geographer-administrator in Mamluk Egypt . His information about the empire came from visiting Malians taking the hajj , or pilgrim's voyage to Mecca . He had first-hand information from several sources, and from a second-hand source he learned of the visit of Mansa Musa . The traveller Ibn Battuta , who visited Mali in 1352 left
2088-419: Is considered one of the most effective tanning compounds. Chromium-tanned leather can contain between 4 and 5% of chromium. This efficiency is characterized by its increased hydrothermal stability of the skin, and its resistance to shrinkage in heated water. Vegetable tanning uses tannins (a class of polyphenol astringent chemicals), which occur naturally in the bark and leaves of many plants. Tannins bind to
2204-403: Is consistent with cross-linking by polychromium species, of the sort arising from olation and oxolation. Before the introduction of the basic chromium species in tanning, several steps are required to produce a tannable hide. The pH must be very acidic when the chromium is introduced to ensure that the chromium complexes are small enough to fit between the fibers and residues of the collagen. Once
2320-416: Is excellent for use in handbags and garments. After application of the chromium agent, the bath is treated with sodium bicarbonate in the basification process to increase the pH to 3.8–4.0, inducing cross-linking between the chromium and the collagen. The pH increase is normally accompanied by a gradual temperature increase up to 40 °C. Chromium's ability to form such stable bridged bonds explains why it

Wet white is a term used for leathers produced using alternative tanning methods that produce an off-white colored leather. Like wet blue, wet white is also a semifinished stage. Wet white can be produced using aldehydes , aluminum, zirconium, titanium, or iron salts, or a combination thereof. Concerns with
2668-428: Is preferred. Once bating is complete, the hides and skins are treated by first soaking them in a bath containing common salt (sodium chloride), usually 1 quart of salt to 1 gallon of hot water. When the water cools, one fluid ounce of sulfuric acid is added. Small skins are left in this liquor for 2 days, while larger skins between 1 week and as much as 2 months. In vegetable tanning, the hides are made to soak in
2784-421: Is tawed by soaking in a warm potash alum and salts solution, between 20 and 30 °C (68 and 86 °F). The process increases the hide's pliability, stretchability, softness, and quality. Then, the hide is air dried (crusted) for several weeks, which allows it to stabilize. The use of alum alone for tanning rawhides is not recommended, as it shrinks the surface area of the skin, making it thicker and hard to
2900-420: Is the characteristic of the keratin class of proteins that gives strength to hair and wools (keratin typically makes up 90% of the dry weight of hair). The hydrogen atoms supplied by the sharpening agent weaken the cystine molecular link whereby the covalent disulfide bond links are ultimately ruptured, weakening the keratin. To some extent, sharpening also contributes to unhairing, as it tends to break down
3016-445: Is the name of a town or a region. Ibn Battuta who visited the capital city from 1352 to 1353, called it Mali. The 1375 Catalan Atlas portrayed a "city of Melly" ( Catalan : ciutat de Melly ) in West Africa. Leo Africanus said that the capital city was called Melli. However, Ibn Fadlallah al-Umari gives Mali as the name of the capital province and Ibn Khaldun refers to Mali as a people, with each giving different names for

Some oral traditions agree with Ibn Khaldun in indicating that a son of Sunjata, named Yerelinkon in oral tradition and Wali in Arabic, took power as Sunjata's successor. Two more of Sundiata's sons would reign, as well as a grandson, before a former slave Sakura , seized power. He

Formaldehyde and arsenic, which are used for leather finishing, cause health problems in the eyes, lungs, liver, kidneys, skin, and lymphatic system and are also considered carcinogens. The waste from leather tanneries is detrimental to the environment and the people who live in it. The use of old technologies plays
3364-461: Is used in leather crafting and in making small leather items, such as wallets, handbags and clothes. Chromium(III) sulfate ( [Cr(H 2 O) 6 ] 2 (SO 4 ) 3 ) has long been regarded as the most efficient and effective tanning agent. Chromium(III) compounds of the sort used in tanning are significantly less toxic than hexavalent chromium , although the latter arises in inadequate waste treatment. Chromium(III) sulfate dissolves to give
3480-497: The Sumerians began using leather, affixed by copper studs , on chariot wheels . The process of tanning was also used for boats and fishing vessels: ropes, nets, and sails were tanned using tree bark. Formerly, tanning was considered a noxious or "odoriferous trade" and relegated to the outskirts of town, among the poor. Tanning by ancient methods is so foul-smelling that tanneries are still isolated from those towns today where
3596-621: The Wolof Empire allowed Mali to reassert authority over some of its former subjects on the north bank of the Gambia, such as Wuli , by 1576. The swan song of the Mali Empire came in 1599, under the reign of Mansa Mahmud IV . The Songhai Empire had fallen to the Saadi Sultanate of Morocco eight years earlier, and Mahmud sought to take advantage of their defeat by trying to capture Jenne . Mahmud sought support from several other rulers, including

Such impermanent capitals are a historically widespread phenomenon, having occurred in other parts of Africa such as Ethiopia , as well as outside Africa, such as in the Holy Roman Empire . The Mansas of Mali used several symbols to demonstrate their power and influence. A red banner struck with a golden disc, referred to as
3828-506: The 'Mali djondjon' or the 'Sun Banner' of Sundiata, appears in oral histories of his coronation. Written sources have Mansa Musa using a similar banner, 'with yellow symbols ( shi’ār ) on a red background', during his visit to Cairo, as well as a parasol. Ibn Battuta records the Mansa using golden and silver lances as imperial regalia. Other royal items included a ruler's cap, slippers, arrows, and bow. The material of which they were made indicated
3944-528: The 1800s, is chrome tanning, where chromium salts are used instead of natural tannins. Tanning hide into leather involves a process which permanently alters the protein structure of skin, making it more durable and less susceptible to decomposition and coloring. The place where hides are processed is known as a tannery . The English word for tanning is from medieval Latin tannāre , derivative of tannum ( oak bark ), from French tan (tanbark), from old-Cornish tann (oak). These terms are related to
4060-582: The Abubakrids, the lineage of Mansa Musa. Al-Umari, who wrote down a description of Mali based on information given to him by Abu Sa’id 'Otman ed Dukkali (who had lived 35 years in the capital), reported the realm as being square and an eight-month journey from its coast at Tura (at the mouth of the Senegal River) to Muli. Umari also describes the empire as being south of Marrakesh and almost entirely inhabited except for few places. Mali's domain also extended into
4176-543: The Mali Empire before the 13th century is unclear, as there are conflicting and imprecise accounts by both Arab chroniclers and oral traditionalists . The first ruler for which there is accurate written information is Sundiata Keita, a warrior-prince of the Keita dynasty who was called upon to free the local people from the rule of the king of the Sosso Empire , Soumaoro Kanté . The conquest of Sosso in c. 1235 marked

A city called Dieriba or Dioliba is sometimes mentioned as the capital or main urban center of the province of Mande in the years before Sundiata, that was later abandoned. Many oral histories point to a town called Dakajalan as the original home of the Keita clan and Sundiata's childhood home and base of operations during

At the local level (village, town and city), kun-tiguis (heads of family) elected a dougou-tigui (village-master) from a bloodline descended from that locality's founder. The county level administrators called kafo-tigui were appointed by the governor of the province. Only at the state or province level was there any real interference from
4640-577: The Songhai Empire, sacked the capital of Mali and purportedly used the royal palace as a latrine. However, the Songhai did not maintain their hold on the Malian capital. Mali's fortunes seem to have improved in the second half of the 16th century. Around 1550, Mali attacked Bighu in an effort to regain access to its gold. Songhai authority over Bendugu and Kala declined by 1571, and Mali may have been able to reassert some authority over them. The breakup of

The Manden city-state of Ka-ba (present-day Kangaba ) served as the capital and name of the province. From at least the beginning of the 11th century, Mandinka kings ruled Manden from Ka-ba in the name of the Ghanas. The ruler was elected from among

The mansa's second in command was a general, thought to have been chief of the armed forces. The santigui was the chief of the treasury and managed the royal granaries and valuable goods such as gold and gems. The griot played a very important role in the royal court. He was the tutor of princes and master of ceremonies, and served as an advisor to

Niani's reputation as an imperial capital may derive from its importance in the late imperial period, when the Songhai Empire to the northeast pushed Mali back to the Manding heartland. Several 21st century historians have firmly rejected Niani as a capital candidate based on

The Malian government soon began promoting the historicity and importance of this oath, an entirely different document from the Kouroukan Fouga charter, and submitted it to UNESCO for inclusion on its list of Intangible Cultural Heritage of Humanity . In 2009 UNESCO duly listed the "Manden Charter, proclaimed in Kurukan Fuga", but the description of the charter clearly referred to
5568-541: The capital city itself. Whether Mali originated as the name of a town or region, the name was subsequently applied to the entire empire ruled from Mali. Another hypothesis suggests that the name Mali is derived from Mandé mali " hippopotamus ", an animal that had special significance to the Keitas, and that Mandé means "little manatee". A legend claims that Sunjata transformed into a hippopotamus. However, these hypotheses have been rejected by locals and are inconsistent with
5684-545: The capital in 1670. The Mali Empire rapidly disintegrated, being replaced by independent chiefdoms. The Keitas retreated to the town of Kangaba , where they became provincial chiefs. Much of the recorded information about the Mali Empire comes from 14th century Tunisian historian Ibn Khaldun , 14th century Moroccan traveller Ibn Battuta and 16th century Andalusian traveller Leo Africanus . The other major source of information comes from Mandinka oral tradition , as recorded by storytellers known as griots . Imperial Mali

Kouyaté structured The Charter, without falsifying the essential point, talking here about the modern juridical texts with a view to make it readable for contemporaries". Niang lists ten "traditional communicators" on whose authority
8468-406: The hexaaquachromium(III) cation, [Cr(H 2 O) 6 ] , which at higher pH undergoes processes called olation to give polychromium(III) compounds that are active in tanning, being the cross-linking of the collagen subunits. The chemistry of [Cr(H 2 O) 6 ] is more complex in the tanning bath rather than in water due to the presence of a variety of ligands. Some ligands include the sulfate anion,
8584-406: The hides are soaked in clean water to remove the salt left over from curing and increase the moisture so that the hide or skin can be further treated. To prevent damage of the skin by bacterial growth during the soaking period, biocides , typically dithiocarbamates , may be used. Fungicides such as TCMTB may also be added later in the process, to protect wet leathers from mold growth. After 1980,
8700-454: The humane treatment of slaves , which states: Paragraph 20 states: "Do not ill treat the slaves. You should allow them to rest one day per week and to end their working day at a reasonable time. You are the master of the slaves but not of the bag they carry." Prompted by the publication of the Kouroukan Fouga, in 2003 Malian historian Youssouf Tata Cisse published the "Hunter's Oath", supposedly sworn by Sundiata's troops upon his coronation in
8816-512: The hypothetical Proto-Indo-European * dʰonu meaning ' fir tree'. (The same word is source for Old High German tanna meaning 'fir', related to modern German Tannenbaum ). Ancient civilizations used leather for waterskins , bags, harnesses and tack, boats, armour , quivers , scabbards , boots , and sandals . Tanning was being carried out by the inhabitants of Mehrgarh in Pakistan between 7000 and 3300 BCE. Around 2500 BCE ,
8932-439: The king. The mansa often liked to play the role "father of his people", dispensing justice himself in solemn sessions, and he listened personally to a subject's grievances against a farin . The post of farin was very prestigious, and his descendants could inherit it with the mansa' s approval. The mansa could also replace a farin swiftly. Most of the empire consisted of autonomous kingdoms of communities who recognized
9048-404: The latter may have begun as a suburb of the former. According to Jules Vidal and Levtzion, citing oral histories from Kangaba and Keyla, another onetime capital was Manikoro or Mali-Kura, founded after the destruction of Niani. Parallel to this debate, many scholars have argued that the Mali Empire may not have had a permanent "capital" in the sense that the word is used today, and historically
9164-433: The laws by which the people would live. The name Kurukan Fuga is a toponym , translating to "clearing on granite/lateritic rock", referring to the plain near where the narrative has Sundiata Keita present the charter. This is often claimed to have been near the town of Ka-ba (present day Kangaba ), following the interpretation of Djibril Tamsir Niane , but other scholars have argued that oral histories more commonly place
9280-504: The legacy of the Mali Empire. The resulting text, not coincidentally, emphasizes the importance of the Kouyate family, who organized the meeting. Jan Jansen takes this one step further, labeling both the Kouroukan Fouga and the Hunters' Oath acts of historical "bricolage" (essentially ' DIY ') rather than credible documents. Simonis and Jansen also see the widespread acceptance and historicization of
9396-475: The maltreatment of prisoners and slaves, installing documents between clans which clearly stated who could say what about whom. Also, Sundiata divided the lands amongst the people assuring everyone had a place in the empire and fixed exchange rates for common products. The final incarnation of the Gbara, according to the surviving traditions of northern Guinea , held 32 positions occupied by 28 clans. It functioned as
9512-447: The mansa's djeli called the belen-tigui (master of ceremonies), or may have been reserved for a female monitor since the constitution states women are to be represented at all levels of government (edict 16). Article 7 institutes the sanankuya (a type of cousinage or joking relationship that is a longstanding West African social tradition) as a civic duty. Kouyaté in his commentary draws attention to paragraph 20, dealing with
9628-455: The modern-day countries of Senegal, southern Mauritania , Mali, northern Burkina Faso , western Niger , the Gambia , Guinea-Bissau , Guinea, the Ivory Coast and northern Ghana. By 1350, the empire covered approximately 478,819 square miles (1,240,140 km ). Al-ʿUmari reported that Mali had fourteen provinces. His list does not necessarily accurately reflect the actual organization of
9744-478: The modernity found in the Mande Charter, as a universal human rights charter that is also deductive and systematic , is its positive formulation , which expresses intent to establish an ideal realm rooted in fraternity , equality , freedom , and justice . Nesbitt indicates that its principles of universal human rights are drawn from a foundational concept of human dignity . Amid an enslavement system that
9860-442: The monarch were governed by strict protocol. Conquered areas were ruled directly by the state through a farin (also called farin-ba or farba ), essentially a military governor, chosen by the Mansa. Duties of the farin included managing the garrison, collecting taxes and customs duties, and controlling the local administration of justice. He could also take power away from the native administration if required and raise an army in
9976-401: The monopoly on certain trades, which included but was not limited to smelting , woodworking , and tanners . Lastly, there were 4 clans of djeli (masters of speech) who recorded the history of the empire through song. Combined these would make up the 29 seat Gbara at the plain of Kouroukan Fougan (named after the event where Sundiata "divided the world"). The 30th seat was likely occupied by
10092-590: The new empire into ruling clans (lineages) that were represented at a great assembly called the Gbara . There were 16 clans known as the Djon-Tan-Nor-Woro (quiver carriers) responsible for leading and defending the empire. There were also 4 clans known as the Mori-Kanda-Lolou (guardians of the faith) who guided the ruling clans in matters of Islamic law . There were 4 nyamakala clans (people of caste ) who had
10208-447: The old methods are used. Skins typically arrived at the tannery dried stiff and dirty with soil and gore. First, the ancient tanners would soak the skins in water to clean and soften them. Then they would pound and scour the skin to remove any remaining flesh and fat . Hair was removed by soaking the skin in urine , painting it with an alkaline lime mixture, or simply allowing the skin to putrefy for several months then dipping it in
10324-611: The point that bacteria are unable to grow. In wet-salting, the hides are heavily salted, then pressed into packs for about 30 days. In brine -curing, the hides are agitated in a saltwater bath for about 16 hours. Curing can also be accomplished by preserving the hides and skins at very low temperatures. The steps in the production of leather between curing and tanning are collectively referred to as beamhouse operations. They include, in order, soaking, liming , removal of extraneous tissues (unhairing, scudding and fleshing), deliming , bating or puering, drenching, and pickling. In soaking,
10440-508: The process. Chemicals used in tanned leather production increase the levels of chemical oxygen demand and total dissolved solids in water when not disposed of responsibly. These processes also use large quantities of water and produce large amounts of pollutants. Boiling and sun drying can oxidize and convert the various chromium(III) compounds used in tanning into carcinogenic hexavalent chromium , or chromium(VI). This hexavalent chromium runoff and scraps are then consumed by animals, in
10556-458: The province or administer it outright. Conquered territories that had proven quiescent could receive this level of autonomy rather than remain under direct rule, but territories that were crucial to trade or subject to revolt could and did lose this privilege as well and have a farin installed to rule over them. Mali was densely populated with the Tarikh al-Sudan stating: "The territory of Jenne
10672-413: The rank of the holder: gold was the highest, and reserved for the Mansa, followed in descending order by silver, brass, iron, and wood. The rulers of Kaabu held a silver lance, for example, while the king of Guinala , one of their subordinates, held a bow and arrows of iron. The majority of the population were farmers, with this being the base of the economy, and food was abundant. Whilst cattle-rearing
10788-482: The reign of Mamluk Sultan An-Nasir Muhammad (r. 1298–1308), but died on his voyage home. Mansa Musa took the throne in c. 1312 . He made a famous pilgrimage to Mecca from 1324 to 1326, where his generous gifts and his expenditure of gold caused significant inflation in Egypt. Maghan I succeeded him as mansa in 1337, but was deposed by his uncle Suleyman in 1341. It was during Suleyman's 19-year reign that Ibn Battuta visited Mali. Suleyman's death marked
10904-545: The rise of Kaniaga, was the son of Niani's faama , Nare Fa (also known as Maghan Kon Fatta, meaning the handsome prince). Upon his father's death, he was forced into exile along with his mother and two sisters. After many years in exile, Sundiata led the combined armies of Mema , Wagadou and the Mandinka city-states in a revolt against the Kaniaga Kingdom around 1234. The combined forces of northern and southern Manden defeated
11020-399: The ruler's cabinet, with different dignitaries given different portfolios (war, justice, economy, foreign relations, religion, etc.), and all major social groups of Mande society were represented. The Mali Empire covered a larger area for a longer period of time than any other West African state before or since. What made this possible was the decentralised nature of administration throughout
11136-509: The same word across different languages and dialects. The version recorded by medieval Arab geographers is Mali ( Arabic : مالي , romanized : Mālī ). Mali is the Fula form of the word. In the Manding languages , the modern descendants of the language spoken at the core of the Mali Empire, Manden or Manding is the name of the region corresponding to the heartland of the Mali Empire. Medieval sources are divided over whether Mali
11252-571: The state. According to Burkinabé writer Joseph Ki-Zerbo , the farther a person travelled from the capital, the more decentralised the mansa 's power became. Nevertheless, the mansa managed to keep tax money and nominal control over the area without agitating his subjects into revolt. The Malian state balanced centralization and decentralization by dividing the empire into a series of provinces and vassal states that had been either conquered or annexed, respectively. These were administered in different ways. The Mali Empire reached its largest area under
11368-403: The tanning agent (chromium salts). Later during pickling, collagen carboxyl groups are temporarily protonated for ready transport of chromium ions. During basification step of tanning, the carboxyl groups are ionized and coordinate as ligands to the chromium(III) centers of the oxo-hydroxide clusters. Tanning increases the spacing between protein chains in collagen from 10 to 17 Å. The difference
11484-551: The territorial domains of Mali showed that it was still a kingdom of considerable size. However, from 1507 onwards neighboring states such as Diarra , Great Fulo , Yatenga , and the Songhai Empire chipped away at Mali's borders. In 1542, the Songhai invaded the capital but were unsuccessful in conquering the empire. During the 17th century, the Mali Empire faced incursions from the Bamana Empire , who ultimately sacked and burned
11600-618: The text was reconstructed. Siriman Kouyaté, the author of the reconstruction, is listed as one of the ten authorities. Niang adds that "the original text in Malinke is available on the digital data bank ARTO". The ten sources are listed as follows: The reconstructed Kouroukan Fouga, as published by Kouyaté, contains 44 edicts. They are divided into four sections concerned with Social Organization (edicts 1-30), Property Rights (edicts 31-36), Environmental Protection (edicts 37-39) and Personal Responsibilities (edicts 40-44). The Kouroukan Fouga divided
11716-585: The threat of Tenguella , but this came to nothing. Songhai forces under the command of Askia Muhammad I defeated the Mali general Fati Quali Keita in 1502 and seized the province of Diafunu. In 1514, the Denianke dynasty was established in Tekrour and it was not long before the new kingdom of Great Fulo was warring against Mali's remaining provinces. In 1544 or 1545, a Songhai force led by kanfari Dawud , who later succeeded his brother Askia Ishaq as ruler of
11832-407: The touch. If alum is applied to the fur, it makes the fur dull and harsh. Depending on the finish desired, the leather may be waxed, rolled, lubricated, injected with oil, split, shaved, or dyed. The tanning process involves chemical and organic compounds that can have a detrimental effect on the environment. Agents such as chromium, vegetable tannins, and aldehydes are used in the tanning step of
11948-492: The toxicity and environmental impact of any chromium (VI) that may form during the tanning process have led to increased research into more efficient wet white methods. The conditions present in bogs, including highly acidic water, low temperature, and a lack of oxygen, combine to preserve but severely tan the skin of bog bodies . Tawing is a method that uses alum and other aluminium salts , generally in conjunction with binders such as egg yolk, flour, or other salts. The hide
12064-452: The twelve kings relinquished their kingdom to the Keita dynasty. In return for their submission, they became "farbas", a combination of the Mandinka words "farin" and "ba" (great farin). Farin was a general term for northern commander at the time. These farbas would rule their old kingdoms in the name of the mansa with most of the authority they held prior to joining the empire. The Mansa held ultimate, unquestioned authority. Audiences with
12180-675: The universal human rights charters of European modernity (e.g., Spinoza , Kant , French Revolution , Age of Enlightenment , Declaration of the Rights of the Man and of the Citizen of 1793 ) by hundreds of years. In comparison to the Magna Carta , Capitulatio de partibus Saxoniae , and Code Noir , Nesbitt indicates that the Mande Charter is an axiom, without grounding , universalist , vitalist (e.g., soul, spirit), and egalitarian , which states: “Every life
12296-418: The use of pentachlorophenol and mercury -based biocides and their derivatives was forbidden. After soaking, the hides are treated with milk of lime (a basic agent) typically supplemented by "sharpening agents" (disulfide reducing agents) such as sodium sulfide , cyanides , amines , etc. This: The weakening of hair is dependent on the breakdown of the disulfide link of the amino acid cystine , which
12412-477: The vicinity of Mema, Ghana, and Diafunu. The identity of the capital city of the Mali Empire is a matter of dispute among historians. Scholars have located the capital in Niani, or somewhere on the Niger, or proposed that it changed several times, that there was no true capital, or even that it lay as far afield as the upper Gambia River in modern-day Senegal . Seemingly contradictory reports written by Arab visitors,
12528-619: The war against the Soso. It may have been located close to modern Kangaba . Mande bards in the region speak of the Dakajalan site, containing Sundiata's grave, as sacrosanct. Kangaba became the last refuge of the Keita royal family after the collapse of the Mali Empire, and so has for centuries been associated with Sundiata in the cultural imagination of Mande peoples. If Dakajalan was, in fact, situated near Kangaba, this may also have contributed to their conflation, beginning with Delafosse's speculation that
12644-552: The words and the message arrives almost immediately at its destination and the man in question goes to the meeting place" The Gbara or Great Assembly would serve as the Mandinka deliberative body and council of state until the collapse of the empire in 1645. Its first meeting, at the famous Kouroukan Fouga (Division of the World), had 29 clan delegates presided over by a belen-tigui (master of ceremony). The Kouroukan Fouga put in place social and economic reforms including prohibitions on
12760-448: Was a speciality of the Fulani , peoples of the Niger were raising sheep, goats, and cattle by the 14th century. The Bozo , Somono , and Sorko people specialised in fishing. Tanning (leather) Historically, vegetable based tanning used tannin , an acidic chemical compound derived from the bark of certain trees, in the production of leather. An alternative method, developed in
12876-650: Was able to stabilize the political situation in Mali. Under his leadership, Mali conquered new territories and trade with North Africa increased. After Sakura's death, power returned to the line of Sunjata, with Qu taking the throne. He was succeeded by his son Muhammad , who launched two voyages to explore the Atlantic Ocean . After the loss of the first expedition, Muhammad led the second expedition himself. He left his cousin Kanku Musa in charge during his absence. Eventually, due to Muhammad's failure to return, Musa
12992-487: Was adopted by tanners. The tanning process begins with obtaining an animal skin. When an animal skin is to be tanned, the animal is killed and skinned before the body heat leaves the tissues. This can be done by the tanner, or by obtaining a skin at a slaughterhouse, farm, or local fur trader. Before tanning, the skins are often dehaired, then have fat, meat and connective tissue removed. They are then washed and soaked in water with various compounds, and prepared to receive
13108-497: Was introduced along with Islam, and predating the declarations of 1776 and 1789 , Nesbitt indicates that the Mande Charter was the earliest declaration to seek abolition of enslavement , beyond moral assertion, through the establishment of an emancipatory government. Historian Francis Simonis has observed that the Kankan workshop did not invite any Malian griots, perhaps due to a perceived rivalry between Mali and Guinea over claims to
13224-529: Was recognized as mansa in approximately 1312. The reign of Kankan Musa, better known as Mansa Musa , is considered the golden age of Mali. A devout and well-educated Muslim, he took an interest in the scholarly city of Timbuktu , which he peaceably annexed in 1324, and transformed Sankore from an informal madrasah into an Islamic university. Mansa Musa Keita's crowning achievement was his famous 1324 pilgrimage to Mecca . Accounts of how many people and how much gold he spent vary. All of them agree that he took
13340-480: Was the largest empire in West Africa, widely influencing the culture of the region through the spread of its language , laws, and customs. The empire began as a small Mandinka kingdom at the upper reaches of the Niger River , centered around the Manding region . It began to develop during the 11th and 12th centuries as the Ghana Empire , or Wagadu, declined and trade epicentres shifted southward. The history of
13456-486: Was used in the Mediterranean world. Rather, authority would rest with the mansa and his court, wherever he went. Therefore, Arabic visitors may have assigned the "capital" label merely to whatever major city the mansa was based out of at the time of their visit. It has been suggested that the name given in the Arabic sources for the capital of Mali is derived the Manding word "bambi", meaning " dais ", and as such refers to
