102 Ancient African Civilizations Ancient African Civilizations, flourished in Africa before the arrival of European colonial powers. The great chiefdoms, states, and empires of Africa were some of the last great civilizations of antiquity to come to the attention of the Western world. Before the 15th century, when the coasts of Africa fell increasingly within the European trading sphere, the states of the African interior were known in Europe only through frail rumors received at one remove from the Arabic world. By the time Europeans finally achieved the interior vastness of the continent in the 19th century, many of its great polities had been reduced by internal dissension or had withered away leaving only their ruins. Oral traditions also remained, but for many years they went unheard or uncredited by the ear of the colonizer. Since the last few decades of the colonial era, much has been reconstructed about the vanished African past, through the use of oral traditions, a few textual sources (mostly in Arabic), historical linguistics, and—most of all—by archaeological research. Virtually every new program of field research provides alterations to the status quo of African prehistory. However, outside of southeastern Africa, interdisciplinary studies incorporating oral histories, linguistics, and comparative ethnography are still very rare. Thus, it must be remembered that any synthesis in this rapidly changing field is imminently liable to augmentation. Despite this, it is possible to highlight the salient features of our current knowledge of the first African states. In their distribution, the ancient complex societies of Africa cluster around the great water bodies of the continent. The Niger and Nile river basins have both figured prominently in the rise of African states, as have the Congo River and the shores of the Red Sea and the Indian Ocean. It will be observed in the earliest state formations of Saharan and Sub-Saharan Africa that two factors played central roles: livestock wealth and interregional trade, with the latter eclipsing the former in importance over time. Although much was made in first postcolonial African histories of the role of external trade in the formation of African states, archaeological research has indicated that extensive internal, rather than external, trade webs formed the principal impetus for the formation of African complex societies. II AFRICA AND EGYPT Much has been written in recent years about the connections of Egypt and the African interior (see Egypt, Ancient Kingdom of). Whether concerning Egypt in Africa or Africa in Egypt, the fountainhead of this new literature was the work of the late Cheikh Anta Diop. Embraced by the public, and uncomfortably ignored by professional scholars, Diop's radical tenets posited that all original early Holocene (c. 10,000-4000 B.C.E.) inhabitants of North Africa were black, and that they alone were responsible for the predynastic culture of Egypt, and for all of the early dynasties. During the Old Kingdom it was thought that small-scale Caucasoid incursions from the Levant lightened the skin tone of the original Egyptians, with subsequent "invasions" from Persia, Greece, and Rome further transforming the physical characteristics of the Egyptians. Needless to say, this in-mixing of foreigners was thought to be linked to the decline of Egypt, with the best of Egyptian ideas being responsible for the grandeur of Greece and subsequent European civilization. This is not the place to enter into a point-by-point debate on Diop's claims, and those of his numerous intellectual descendants. At their best they do much to redress the anti-African bias inherent in early Egyptology; at their worst they recreate in reverse the oblique racism inherent in the hyperdiffusionistic school of Grafton Elliot-Smith in the 1930s. Modern consensus sees Egypt, from its beginnings, as a multiracial civilization, with African cultural aspects particularly coming from Egypt's Nubian corridor to Africa. The great civilization of Egypt developed between Mediterranean and African spheres of influence out of a long tradition of incipient stratified social systems, already boasting well-organized agro-pastoral economies, ceremonial architecture, and sailing craft (the predynastic, 5500-3100 B.C.E). Between 3100 and 331 B.C.E, Egyptian dynasties would profoundly influence socioeconomic developments in northeast Africa and southwest Asia, and forever alter the landscape of Egypt with some of the most impressive monuments known to humanity. Throughout this time Egypt's neighbors in Nubia possessed their own unique cultural institutions and political structures. These southern polities sometimes cooperated and sometimes contested the power of their northern neighbor. Kerma, potentially the first Nubian state, prospered between the third and fourth cataracts of the Nile from roughly 2500 to 1500 B.C.E. During Kerma's earliest development, its cultural influences were undoubtedly from the African Sahel, manifested in round dwellings and ceremonial structures, as well as distinctive burial practices and circular tumuli featuring livestock sacrifices. Over time, however, the cultural proximity of Egypt becomes increasingly visible in linear-walled, fired mud-brick architecture; more elaborate burial practices; and prestige goods imported from the lower Nile (Middle to Final Kerma, c. 2050-1500 B.C.E). Kerma's economy appears to have been based upon external trade in ivory, diorite, and gold to the north, with its subsistence base founded upon pastoralism and an as yet unverified grain component. From 1550 B.C.E onward, Egypt began a period of violent conflict with Kerma, which culminated in the fall and burning of Kerma sometime around 1500 B.C.E After the collapse of Kerma, following a period of Egyptian domination, other Nubian states would arise in the same region. The most notable of these were Napata (c. 860-270 B.C.E) and Meroe (c. 270 B.C.E-350 c.e.). Napata formed around a reemergent upper Nubian elite, with a heartland situated south of Kerma, during a time of dissension in Egypt. Its first rulers were buried in a monumental cemetery at Kurru, with later rulers being inhumed near Napata. With Egypt fragmented into approximately 11 competing polities in the early 1st millennium B.C.E, Napata was able to push its influence northward, ruling Egypt as a pharaonic dynasty from 750 to 660 B.C.E Egypt then reunited under an indigenous dynasty, and Napata's sphere of influence contracted to its original center. From the declining Napatan state, Meroe arose and endured for more than 500 years (c. 270 B.C.E-350c.e.). Its center was the royal court at Meroe, although it was eventually to stretch as a mercantile empire into lower Nubia and the frontiers of Ptolemaic Egypt. William Adams, the first great synthesist of Nubian archaeology, wrote that both Ptolemaic Egypt and Meroe were "provincial expressions of a world civilization." In other words, they were both cultural outposts of Hellenistic Greece. Even the most fervent Africanists would be hard-pressed to argue against this sentiment. From Classic Kerma onward there is a progressive cultural trend in Nubia of looking away from Africa, and toward the Mediterranean world. However, Meroe did retain some of its own gods—most notably the lion-headed Apedemack. Meroe also developed its own hieroglyphic-derived script, which unfortunately is as yet untranslatable. Meroe is also famed for its massive iron production, the first large-scale industry of its kind in the Nile Valley. But the technology of this industry is essentially Roman, rather than Sub-Saharan. Indeed, although Sub-Saharan animals, both as living circus animals or as animal products, continued to flow through Nubia, the region had by this time become more of a cul- de-sac and less of a corridor, seeking its luxuries and ideals from the Greco-Roman world. III CATTLE AS CAPITAL: EARLY SOCIETIES OF THE SAHARA AND SAHEL COMPLEX By the 3rd millennium B.C.E, a broad swath of cultures economically dominated by pastoralism stretched across the African Sahel, from modern Sudan to Mauritania. At that time the Sahara was much moister than it is today, being carpeted with grasslands and crisscrossed by seasonally filled waterways and ponds. Its vast expanse was also populated with linguistically and culturally diverse groups that had both pastoral and hunter-gatherer ways of life. The small stone and earthen tumuli and monuments left in the wake of the early pastoral cultures attest to a degree of social ranking in the former—probably based around the accumulation of livestock and widely traded polished stone objects (beads, arm rings, axes, etc.). The origins of these mobile complex societies extend almost to the beginnings of cattle-keeping in Africa, whose origins may be as early as 7000 B.C.E in the northeastern corner of the continent. From a relatively early date, they were constructing small stone monuments of a communal nature, including a circle of standing stones (built between 5000 and 4000 B.C.E, near Nabta Playa, Egypt), and small tumuli for cattle "sacrifices" or lineage bulls (c. 5000 B.C.E, Niger and Chad). Soon, however, monuments of a more individualistic nature would appear across the central Sahara. Stone tumuli, alignments, and burial complexes, singling out the elites of these societies for special treatment, are well documented from 4000 B.C.E until the virtual abandonment of the gradually desiccating region during the 1st millennium B.C.E . In two places, environmental and external social factors crystallized these mobile societies into more sedentary and complex polities, such as those known from Kerma (see the section on Africa and Egypt) and Dhar Tichitt. Around 1500 B.C.E, far in the west of the continent, the first substantial masonry structures in Africa outside the Nile Valley were being built. Along the escarpments of Dhar Tichitt and Dhar Oualata, in modern Mauritania, a pristine chiefdom developed in a deteriorating environment where arable land and pasturage were at a premium. Remote sensing has revealed a four-tier settlement hierarchy, with the largest regional centers exceeding 90 hectares (220 acres) in area. The evolution of Tichitt-Oualata society remains unclear, with competing hypotheses of long-term local development, rapid evolution, or immigration from elsewhere being obscured by thin stratigraphy at deflated settlement sites. By the mid—2nd millennium B.C.E, however, it is clear that pastoral peoples living in this zone had started to become more sedentary, building dry-stone masonry structures and cultivating millet. From this time onward, the presence of large stone-walled corral areas and numerous granary foundations points to the importance of mixed farming, with definite evidence present for domestic millet, cattle, sheep, and goats. Inorganic wealth resided in the same objects valued by contemporary Sahelian pastoral cultures: carnelian and amazonite beads, polished stone bracelets, and a plethora of ax types, from large functional varieties to miniature tokens. Unfortunately, none of this region's many tumuli have yet been excavated. It would appear that the collapse of Tichitt-Oualata between 800 and 500 B.C.E was brought about both by continually shrinking local ponds and grasslands, as well as increasing harassment from Berber interlopers from farther north. IV THE EMPIRES OF GHANA AND MALI During the 1st millennium B.C.E the advent of metallurgy added further impetus to the growth of complex societies south of the Sahara. Indeed, gold would play a key role in international trade between West Africa and the Mediterranean world throughout the late first and early second millennia c.e. At a more regional level, iron and copper figured as crucial sources for both practical and prestige objects. Coupled with ivory and the slave trade , the control of metallurgical commodities supplanted mere subsistence as the power basis of African elites from the beginning of the 1st millennium c.e. By the time Arab geographers began to write of West Africa in the 8th century c.e., the empire of Ghana—described as a "land of gold"—was already in existence. The origins of Ghana, and even its precise extent, remain unclear. But we do know that it was situated within the modern states of Mauritania and Mali. It should be noted that he modern state of Ghana was named after the empire because of possible historical connections, even though geographically there is no relation. It was not until the 10th and 11th centuries C.E. that travelers and compilers of travelers' tales began to assemble a more complete written record of Ghana—an empire reaching the end of its existence by that time. Most notable among them were Ibn Hawkal, a late-10th-century traveler; and the great geographical synthesist al-Bakri, whose masterwork was completed in 1068 C.E. Only eight years after this, the Almoravid Berbers completed their invasion of Ghana and captured its current capital (Koumbi Saleh). It would appear that this act laid waste to the power structure of the state and marked its effective dissolution. In their writings, Ibn Hawkal and al-Bakri paint a picture of a powerful and wealthy state able to "put 200,000 warriors in the field, more than 40,000 of them being armed with bow and arrow." The king, it was said, controlled the traffic of all gold out of his kingdom to the north, and the flow of salt from the Sahara to the south. The ruins of Ghana's last capital, Kumbi Saleh, lie in southeastern Mauritania; yet the most substantive settlement clusters known from the 1st millennium C.E. rest within the bounds of the middle Niger in the neighboring Republic of Mali. Earlier scholarly thought placed Ghana as a puppet state founded by Arab traders, but recent research has emphasized the indigenous development of regional trade webs by the Soninke people, long before the Arab conquest of North Africa (c. 750 C.E.). There is thus an unknown Ghana, the Ghana that existed before the first written accounts. There is a tantalizing reference in the Tarikh as-Sudan, a compilation of oral traditions written in Timbuctu about 1650 C.E. It states that there were 21 kings of Ghana before the beginning of the Muslim era (622 C.E.) and 21 kings after that. If we accept this as anything more than an exercise in symmetry, then it would seem to place the origins of Ghana sometime before 300 C.E. Archaeologically, if we move the center of gravity southward toward the inland Niger Delta, much evidence exists to support this claim. The substantial settlements that have been excavated along the middle Niger were all in existence by this time. At some sites, such as Tongo Maaré Diabal, permanent mud architecture is present from 250 C.E. Certainly the high point of middle Niger civilization in terms of maximum settlement growth would date to the period between 400 and 800 C.E., well before the textually recorded Ghana. Was this the early Ghana eluded to in the Tarikh as-Sudan? On current evidence, it would appear likely. It is expected that future work will confirm the view that the heart of the empire of Ghana, like that of the Mandinka empire of Mali, lay not in its trade entrepôts in the Sahara, but closer to the resource centers of the middle Niger. The inland Niger Delta's best-excavated sequence is that of Djenné-Djeno (250 B.C.E to 1400 C.E.), a 33-hectare (82acre) mud-brick settlement mound. From its foundation, the inhabitants of the site fished, cultivated rice and sorghum, and had domestic livestock. Trade with adjoining regions brought in commodities such as copper, iron, and sandstone. By 450 C.E., local craft specialization, the building of a monumental city wall, and a regional site hierarchy centered on Djenné-Djeno point to an urban status for the site. It must be stressed, however, that Djenné-Djeno is only one of more than a dozen settlements of comparable size now known from the middle Niger, and—if one were to consider smaller settlement mounds— only one of thousands. The occupation of such sites continued through the time of Ghana's Islamic successor states, the empire of Mali (1250-1600 C.E.) and the empire of Songhai (1375-1600 C.E.). With the conquest of Ghana by the Islamic Almoravid movement, and the subsequent rapid disintegration of this movement, there came a brief period of small feudal states in this region of West Africa. These successor kingdoms included those of Soso, in the north of ancient Ghana; and Kangaba, located in the modern Mali/Guinea frontier zone. Kangaba had developed out of a grouping of local Mandinka chiefdoms and stateless societies, probably as a response to slave raiding during the time of the late empire of Ghana. In the early 13th century, animistic Soso, under the rule of Sumanguru Kante, began to expand. It raided the territories of the Mandinka and blocked their way to commerce in the north. Around 1240 C.E., Sundiata Keita, or Mari-Diata, the young ruler of Kangaba, defeated the army of Sumanguru, conquered the north, and gained total control of the West African gold trade routes. With this conquest, Keita founded the empire later known as Mali. Mali was to become the first great Muslim empire of West Africa, eventually controlling much of modern Senegal, Mauritania, Guinea, and Mali. By 1312, Mali's greatest ruler, Mansa Musa, took the throne. He ruled for 25 years, making an elaborate pilgrimage to Mecca in 1324 C.E., during which the gold he lavished on Cairo was to have the effect of ruining the local gold standard. During his reign several monumental mosques were constructed within the territory of modern Mali. However, Mali did not last as long as Ghana, enduring as an empire for less than 200 years. Its short life may have been due to the instability created by its rapid expansion through conquest and its consequent ethnic diversity and potential for internal dissension. Unfortunately, archaeologically we know very little about Mali. Excavations at its putative capital of Niani (in modern Guinea) showed substantial occupations dating to before and after the time of Mali, but very little during its epoch. It is likely that Mali had many capitals, with the capital moving with each new successor to the throne. Much archaeology remains to be done in the Mali/Guinea border region, both to understand better the origins of the Sundiata's power base, and to locate the later centers of Malian rule. V THE IGBO-UKWU, IFE, AND BENIN: GRANDEUR IN WEST AFRICAN FOREST The first complex societies of the West African forest probably took root sometime in the 1st millennium C.E. Limited excavations have only begun to hint at the political organization of these societies during the late 1st millennium C.E., but their richness and artistic expertise have been well demonstrated at the site of Igbo-Ukwu (Nigeria), dated to about 900 C.E. From this site, a regal burial and a storehouse of regalia have been excavated, both holding superb brass castings made by the "lost wax" method, and thousands of glass trade beads. The presence of such wealth hints at a well-organized system of trade, craft specialists, and a wealthy elite; but we know little of settlements in the region until the emergence of the state of Ife around 1100 C.E. The tropical West African state of Ife does not benefit from the weight of textual records available for its contemporaries in the savanna and Sahel. However a good deal of effort has been put into its archaeology, which is a compensating factor. Initial archaeological inquiries at Ife began as long ago as 1910, when the German anthropologist Leo Frobenius visited a shrine at the living holy city of Ife, and there acquired a series of naturalistic bronze and terracotta busts for £6 and some alcohol. He was later apprehended by the colonial authorities and the bronzes returned, but seven terracottas found their way into European museums. As a result there was much speculation as to who could have created this magnificent lifelike sculpture. Frobenius, on stylistic grounds, asserted that ancient Ife was a lost Greek colony founded around 1300 B.C.E and abandoned by 800 B.C.E We now know that this is not even remotely true. The ancient art of Ife was entirely African in its origin, and dated instead to the earlier part of the 2nd millennium C.E. The Yoruba city of Ife is itself an object of wonder. It is surrounded by high earthworks arranged in rings around the town, with the outer ring being 11.6 km (7.2 mi) in circumference. The date of these earthworks is not yet precisely known, but it is assumed that at least some of them correspond with the apogee of Ife as a political center. Archaeological work at Ife and other sites in its vicinity has been driven primarily by accidental discoveries during building activities, as much of its ancient expanse remains covered with habitations, businesses, and public buildings. Excavations have generated a series of radiocarbon dates that allow the reconstruction of a rudimentary cultural sequence. Finds from between 500 and 950 C.E. are mainly of poor grave pits concentrated near the center of the town. However, for the period dating from 950 to 1300 C.E., there are rich graves, numerous ritual structures, and a distribution of finds throughout, and even beyond, the vast area enclosed by the earthworks. Most of the terracotta portrait busts have been thermoluminescence dated to c. 1200-1300 C.E. In some sculptures, personages are depicted richly adorned in ceremonial regalia. Shrines featuring such depictions may point to a form of divine kingship that is known to have existed historically in the region. Perched at the edge of Nigeria's tropical forest, Ife is thought to have come to prominence by the control of local products (ivory, gold, pepper, cola nuts, and slaves) in the external trade to Niger River civilizations. By 1300 C.E. its walled capital was at the peak of its wealth, with many shrines featuring elaborate potsherd pavements and sculptures scattered throughout the city. To support this large elite and artisanal population, Ife's subsistence base appears to have been yams, oil-palm products, and small livestock. Surrounding Ife there was likely to have been a continuous hinterland of farmsteads. Around 1500 C.E., the city of Ife declined, and the region's center of power shifted to Benin, without any appreciable break in cultural tradition, despite the fact that Benin City was founded by a different ethnic group (Edo instead of Yoruba). The rise of Benin and its eclipse of Ife (15th century C.E.) corresponds to the beginning of contacts with the Portuguese and a shift to coastal rather than riverine trade. The first of the great kings of Benin was Oba Euware (1440 C.E.). He is said in oral traditions to have captured 201 towns and made them render regular tribute to him. He is also said to have been the builder of the walls and ditches of Benin, as well as external road networks. From the time of Oba Euware on, there were further innovations in bronze (or more properly brass) casting, with the advent of brass plaques showing the exploits of kings, and with brass pendant plaques being worn by local rulers and functionaries as badges of rank. The walls of Benin are even more spectacular than those of Ife, earning a spot in the Guinness Book of World Records as the world's largest earthwork. Benin City continued to flourish until the advent of the colonial era, when a British punitive expedition sacked the capital in 1897. VI PRE-AKSUMITE AND AKSUMITE CIVILIZATION IN ETHIOPIA Like Meroe, which was more linked to Egypt than Africa, we find in Aksum another outwardly looking state, wedded to the trading sphere of the Red Sea and southern Arabia rather than the African interior. Although there has been some debate concerning the cultural origins of Aksum, it is most likely that there was in fact an undifferentiated Ethiopian/South Arabian cultural sphere from the late 1st millennium B.C.E into the 1st millennium C.E. Unfortunately the epoch most likely to shed important light on this matter, the pre-Aksumite period (500 B.C.E-100 C.E.), has barely been studied. Indeed, little has been well documented save several religious and funerary shrines bearing South Arabian inscriptions. The best preserved of these are known from the site of Yeha, where there is a pre-Aksumite temple dedicated to the South Arabian moon god Alouqah. In addition, it can be noted that the distribution of pre-Aksumite material culture more or less equates to that of later Aksum: the northern Ethiopian/Eritrean highlands. Thus, Aksum has been viewed as the successor to this earlier complex society. The last few centuries of the pre-Aksumite period are sometimes referred to as the Intermediate Period. During this time inscriptions in South Arabian script decline, being replaced by a local script based upon the Ge'ez language. Classic Aksumite civilization prospered between 100 and 600 C.E. The first textual mentions of Aksum may be found in the Periplus of the Erythraean Sea, an Alexandrian Greek trading guide published in the late 1st century C.E. The guide makes reference to a metropolis called "Axomite." There is also a mention in Ptolemy's Geography that would lead us to expect a city and a king's palace at Aksum in the mid-2nd century C.E. Archaeologically, during this early Aksumite period, the first stellae are known to have been installed in the funerary park of the city of Aksum. Textual records from South Arabian temples indicate that by the 3rd century C.E., Aksumite armies were fighting with success in southern Arabia, allied with local rulers, and being led in person by the Aksumite king Gadarat. By 270 C.E. Aksum was minting its own coinage, marked with a distinctive disk and crescent symbol and the head of the ruler (in the first case, King Endybis). Between 200 and 330 C.E., Aksum's greatest monuments were erected. These include the underground chambered tombs of Nefas Mawcha and the Tomb of the Brick Arches, as well as the great stellae of Aksum (the largest being 30 m, or 98 ft, in height, and weighing 517 tons). These stellae were carved from single blocks of stone, with low-relief sculpture on their surfaces representing multistoried structures with doors, windows, and beams. By this time we know that Aksum was supplying African luxury goods (particularly ivory and animal skins) to the Red Sea trade, receiving in return precious metals, glass, cloth, wine, and spices. Aksum's most celebrated king, Ezana, came to power around 330 C.E. During his reign Aksum was sovereign over Ethiopia as well as parts of Yemen and Sudan. Ezana converted to Christianity in 333 C.E. There followed a trend toward simpler burial traditions, and the replacement of the disk and crescent with the cross on Aksumite coinage. From C.E. 600 onward, Aksum began to decline. Aksum ceased to be the state's capital in 619 C.E. At this time the kingdom also lost its one seaport of Adulis, as a result of internal dissension. One of the world's first Christian states, Aksum's successors were to retain their religion in the wake of the Islamic expansion of the late 1st millennium C.E. VII THE SWAHILI COAST AND THE EAST AFRICAN INTERIOR Along the East African littoral, during the 1st millennium C.E., coastal trade was to play an important role in the elaboration of local social hierarchies, just as trans-Saharan trade was doing in the west. Likewise, for many years the Swahili civilization—a chain of semiautonomous city-states dotting the East African coast—was thought to be the direct result of Arabian colonization. Its cities were viewed as the very edge of the Islamic world—wealthy trading posts perched on the edge of a foreboding interior from which trade goods would "appear" in exchange for cloth and beads. However, the past few decades of research have exposed the indigenous African roots of the Swahili culture and their eventual synergy with incoming Arabian/Islamic culture. Although the guide written in the late 1st century C.E., Periplus of the Erythraean Sea (see the section on the Aksumite civilization), cites the presence of a trading city (Rhapta) along the coast of Kenya or Tanzania, little substantial archaeological evidence exists for East African trading societies until the 9th century. However, there is some encouraging recent evidence from the site of Unjuja Ukuu (situated at the southern tip of the island of Zanzibar, Tanzania). There, local ceramics have been found in stratigraphy with fragments of Egypto-Roman pottery, with the whole assemblage radiocarbon dated to 400-550 C.E. This at least attests to coastal trade with Roman Egypt by that time, and hints that Rhapta may not be a myth. By 800 C.E., Swahili trading cities dotted the East African coast, fusing Islamic religion and architecture with indigenous sociopolitical organization and commercial acumen. Trading settlements, of which 170 are known, eventually extended from southern Somalia to Mozambique. From these towns the Indian Ocean acted as a trade corridor to the Far East, with lateen and squarerigged dhows stocking the menageries of Chinese emperors, and carrying silks and porcelain to Swahili merchants and their sultans. At an incipient level, it is now apparent that Swahili civilization arose out of coastal agropastoral societies, whose gradual mastery of the sea lanes made them ideal intermediaries with foreign mariners. At the well-studied site of Shanga (Tanzania), mud and thatch indigenous architecture in the 8th and 9th centuries gives way to a local mutation of Islamic mortar and stone buildings in the 10th century; with evidence for longdistance trade being present throughout the site's sequence. At its apex, however, the Swahili coast packed a lavish Islamic veneer, with impressive palaces and mosques distributed among sites such as Kilwa and Gedi. Indeed, by 1331 C.E., the great traveler Ibn Battutah would write "Kilwa is one of the most beautiful and wellconstructed towns in the world." The eventual downfall of the Swahili trading network and its days of glory was brought about by the arrival of Portuguese mariners in the first years of the 16th century. They sacked Kilwa in 1505 and rapidly constructed a chain of stone and wood forts along the eastern seaboard, and the east coast trade soon lost its efficiency. The Portuguese, unlike the Arab traders, did not integrate well into the existing trading community. During the time of the Swahili civilization, numerous complex societies and states grew in the interior, often as trade-item consolidators for the coastal trade. Farthest from the coast were the wealthy societies of the Democratic Republic of the Congo's Upemba Depression, the neighboring Kisalian and Katotian polities (c. 700-1300 C.E.). Both are known for their sumptuous graves, with those of the Kisalian suggesting wealth deriving from an intra-African trade (copper, iron, and ivory), and those from the Katotian suggesting firmer links with Indian ocean commerce (cowries, conus shells, glass beads). The successor to the Kisalian polity was the historic kingdom of Luba. VIII GREAT MAPUNGUBWE) ZIMBABWE (AND ITS PREDECESSOR Farther to the south, trading states developed where Bantu agro-pastoralists had already established transient chiefdoms based upon the manipulation of livestock wealth. The first of these states, Mapungubwe (c. 1000-1200 C.E.), grew up in the South Africa Limpopo River basin. Here, an intermediary role in the coastal trade fossilized existing, and otherwise transient, social hierarchies based upon cattle wealth. Glass trade beads, cowries, and copper ingots came in from the coast to the Mapungubwe hill settlement in exchange for ivory, animal skins, and locally mined gold. From 1075 C.E. it is apparent that artisanal specialists existed at the site, including metal, ivory, and bone workers, as well as spinners of cotton thread. These items would have been of use in both local and external trade. A further elaboration of such hierarchies, but over a greater zone of influence, can be seen in the state of Great Zimbabwe (c. 1100-1450 C.E.). Famed for the towering, dry-stone masonry architecture of its impressive central settlement, the Great Zimbabwe tradition like Mapungubwe consolidated the gold and animal product wealth of its hinterland as a powerful bargaining chip in the competitive coastal trade. It is interesting to note that Great Zimbabwe, like Ife, was once perceived by colonialists as an outpost of peoples foreign to the African continent. Great Zimbabwe first became known to Europeans through Portuguese contacts. By 1506 C.E. there were rumors of a "King Mwene Motapa," who ruled a series of lands ranging from the Kalahari Desert to the Indian Ocean. However, in the 17th century, Portuguese missionaries and historians, who by now had seen the abandoned ruins of the interior, began to cast doubt upon their African origins—interpreting them instead as the remains of the vanished Christian kingdom of Prester John, or King Solomon's mines. The first archaeological investigations at the site in the late 19th century set out merely to determine the nature of Great Zimbabwe's external origins. Such work was supported by Cecil Rhodes, who saw in Great Zimbabwe an ancient Phoenician trading settlement, mirroring the then current British marine hegemony. At this time, much of the site was mined for its valuables by treasure hunters. As the 20th century dawned, a series of professional archaeologists, including Keith Robinson and Gertrude Caton-Thompson, demonstrated through excavations that there was no evidence for a foreign presence at the site, with local (protoShona-) pottery, art, and architectural styles present throughout. Despite this, wrangles over the site's origins would continue until a comparatively recent period, with the site figuring as an important propaganda tool in the Zimbabwean struggle for independence. The site of Great Zimbabwe is only one of over 50 other masonry settlements of its type scattered throughout Zimbabwe and northern Botswana, although it is without doubt the most grandiose. It is now known that Great Zimbabwe was founded in the 11th century C.E. as a relatively small-scale trading and herding center, consisting only of Daga (mud) dwellings dotting the local hills and valleys. But from 1085 C.E. on, profound changes began to take place. First the labyrinthine Hill Ruin was constructed. This high-walled multiroom structure, is accessed only by a precipitous stone stairway winding along the side of the hill. It has been interpreted as royal residence and a spiritual/ritual center. Later, the Valley Ruin, with its muchphotographed cyclopean Elliptical Building, was constructed. With its narrow, three-story-tall entrance passageway, and central court featuring two circular stone towers, it has been interpreted by some as a later king's residence and by others as women's area, perhaps a dwelling for the king's wives or a noblewomen's initiation center. From 1085 to 1450 C.E., Daga huts continued to dot the plains around the stone complexes, taking in almost 100 hectares (250 acres) in area. At its height in the 13th century, Great Zimbabwe's capital was home to as many as 18,000 people. Subsistence to support such population concentrations remained crucial, and it is likely that cattle and agricultural surplus continued to play a highly visible role in the maintenance of power. Contemporary with Great Zimbabwe there is evidence for regional centers subordinate to the central site. The best documented of these is Ingombe Ilede on the Zambezi River. There, the 15th-century graves of local rulers have been excavated. They were adorned with necklaces of local gold and imported glass beads, and wrapped in fine cloth burial shrouds of which traces remain. As was the case elsewhere in Africa, these local nodes of power served to consolidate goods for the external trading center of Great Zimbabwe (for example, ivory, rhinoceros horn, animal skins, gold, and slaves). Undoubtedly Great Zimbabwe owed much of its wealth to international trade, but it was also part of a long-term internal development, with its power based as much upon cattle wealth and military power as foreign riches. The collapse of the Great Zimbabwe occupation is dated to the mid- to late 15th century, when most of the site was abandoned. Reasons posited for Great Zimbabwe's collapse have included the possible exhaustion of local gold, arable land, or water resources, and the disruption of the Indian Ocean trading sphere by the Portuguese. Majestic successor states such as Khami, located farther in the interior, soon sprang up, but none ever achieved the power of Great Zimbabwe.
