Early Cities, Trade, and State Formation

Chapter Opening

On the floodplain of the middle Niger River, in what is today central Mali, archaeologists have uncovered the remains of a city that flourished more than a thousand years before the rise of the great Sahelian empires of Ghana, Mali, and Songhai. The site, known today as Jenné-Jeno, grew from a small fishing and farming settlement around 250 BCE into a substantial urban center with specialized craftspeople, long-distance trade connections, and a population that may have reached several thousand people by the early centuries of the common era. Jenné-Jeno had no monumental palace, no single ruling dynasty that left behind royal inscriptions, and no obvious central authority of the kind historians might expect to find at the heart of an ancient city. And yet it was unmistakably urban: a place where farmers, fishers, ironworkers, potters, and traders lived together at high density, exchanged goods across great distances, and developed shared ways of organizing collective life.

Jenné-Jeno is only one example of a much broader pattern. Across the African continent, urban life and organized political authority developed independently, repeatedly, and often long before contact with the Mediterranean world, the Islamic world, or Europe. Cities grew along the Nile, the Niger, the Senegal, and the Zambezi rivers. They grew on the savannas of West Africa, in the highlands of Ethiopia, on the coast of East Africa, and in the interior plateaus of southern Africa. Some cities grew up around religious shrines and pilgrimage centers. Others grew around markets at the junction of trade routes, around fortified settlements that controlled access to valuable resources, or around the courts of emerging rulers who needed concentrated populations of craftspeople, soldiers, and administrators to support their power.

This chapter asks a deceptively simple question: how and why did cities and organized states emerge across ancient Africa, and what made some settlements grow into dense urban centers while others remained small villages? The answer is not simple, and it is not the same in every region. In some places, trade was the decisive force, as settlements at the crossroads of valuable exchange routes grew wealthy and attracted migrants, craftspeople, and political ambition. In other places, agricultural surplus came first, allowing populations to grow dense enough to support specialized non-farming professions — metalworkers, potters, priests, soldiers, and administrators — who in turn needed organized systems of exchange and authority to sustain them. In still other places, religious or ceremonial functions drew people together at sacred sites that gradually became permanent settlements.

What changed across this long process was profound. Societies that had once organized themselves primarily around kinship — extended families, lineages, and clans — increasingly developed new forms of social organization based on occupation, residence, and political rank. Trade networks that had once been local and occasional became regional and sustained. Authority that had once rested largely on the consent and respect of kin groups increasingly came to rest on control of trade routes, control of specialized production, and the ability to organize collective labor and defense.

What continued, just as importantly, were many of the underlying social structures that had organized African communities for thousands of years. Kinship remained central to identity and obligation even within growing cities. Religious belief and ritual practice continued to shape political authority, often investing rulers and elites with spiritual as well as political legitimacy. Agricultural and pastoral life remained the foundation of most African economies, even as cities grew increasingly dependent on trade and craft production. The transition to urban and state-organized life was gradual, uneven, and never complete: most Africans throughout this period, and for centuries afterward, continued to live in rural farming and herding communities rather than in cities.

Both ordinary people and emerging elites were affected by these changes, though in different ways. Farmers who produced agricultural surplus made urban life possible, even as they often remained at the social and political margins of the cities their labor sustained. Craftspeople — blacksmiths, potters, weavers, leatherworkers — gained new opportunities for specialized livelihoods but also became dependent on markets and patrons beyond their own kin networks. Traders who controlled valuable goods or strategic routes could accumulate wealth and influence that rivaled or exceeded that of hereditary chiefs. Emerging rulers and elites who could control trade, organize defense, and claim religious legitimacy found new tools for building lasting political authority — the foundation of the states and empires examined in later chapters of this textbook.

Historians and archaeologists reconstruct this story using several different kinds of evidence, each with its own strengths and limits. Archaeological excavation reveals the physical layout of ancient settlements, the scale of population growth, the presence of specialized craft production, and the evidence of long-distance trade goods such as glass beads, copper, and cowrie shells found far from their points of origin. Oral traditions, transmitted across many generations, preserve memories of founding ancestors, migrations, and the origins of political authority, even though such traditions must be read carefully and critically. Written sources from North Africa, the Mediterranean world, and later the Islamic world occasionally mention African trading centers and political structures, offering an outside perspective that complements — and sometimes contradicts — internal African traditions and archaeological evidence.

This chapter connects directly to the larger story this textbook tells. The cities, markets, and early states examined here were not isolated curiosities; they were the foundations on which the great African civilizations and empires explored in later chapters — Ghana, Mali, Songhai, the Swahili city-states, Great Zimbabwe, and many others — were built. Understanding how urban life, trade networks, and political authority first developed in Africa is essential to understanding everything that followed.

Guiding Historical Questions

Historical Context

By the time the developments described in this chapter took place, African societies had already undergone the long transition from hunting and gathering to food production described in earlier chapters of this textbook. Agriculture and pastoralism had spread across most of the continent's habitable regions, populations had grown, and village life had become the dominant form of settlement across much of sub-Saharan Africa. Ironworking technology, discussed in Chapter 16, had also spread widely by the middle of the first millennium BCE, providing African farmers with more effective tools and African communities with more effective weapons.

These earlier developments created the preconditions for urbanization. Agricultural surplus — more food than a farming community needed for its own immediate consumption — made it possible for some members of a community to specialize in non-farming activities: making pottery, working metal, weaving cloth, organizing trade, performing religious ceremonies, or governing. Population growth created denser settlements with more complex social needs. Ironworking and other technologies expanded the range of goods that could be produced, traded, and valued.

Geography played a decisive role in determining where these preconditions translated into urban growth. River valleys such as the Nile, the Niger, and the Senegal provided fertile agricultural land, reliable water supplies, and natural transportation corridors that could carry goods and people across long distances with relatively little effort compared to overland travel. Locations at the edge of major ecological zones — where the Sahara desert met the Sahel grasslands, or where forest met savanna — often became important trading points, because they connected communities producing very different goods: desert salt and Mediterranean products on one side, savanna grain and gold on the other, forest kola nuts and other valuable goods further south.

Long-distance trade networks already existed in some form before the rise of the cities examined in this chapter. Evidence of obsidian, marine shells, and other materials moving hundreds of kilometers from their points of origin shows that some form of exchange — whether direct trade, gift exchange, or relay trade through intermediary communities — had connected different regions of Africa for a very long time. What changed during the period covered in this chapter was the scale, intensity, and organization of trade, and the emergence of permanent settlements specifically organized around commercial exchange.

It is also important to understand what urbanization in early Africa was not. It did not mean the disappearance of rural life; the great majority of Africans throughout this period continued to live in farming and herding communities, and cities depended entirely on the agricultural surplus that rural producers supplied. It did not mean the immediate appearance of large centralized states with kings, armies, and written law codes; many early cities, including Jenné-Jeno, appear to have grown and functioned for centuries without clear evidence of centralized political authority in the form familiar from later African empires. And it did not happen everywhere at the same time or in the same way; urbanization in the Nile Valley, the West African Sahel, the East African coast, and the southern African plateau each followed distinct timelines and distinct local logics, even though they shared certain underlying causes.

The Growth of African Cities

A city, in the most basic historical sense, is a permanent settlement with a population dense enough and large enough to support specialized, non-agricultural occupations: craftspeople, traders, religious specialists, administrators, and others who do not produce their own food but instead obtain it through exchange, tribute, or wages. By this definition, cities developed in Africa earlier and more widely than many older historical accounts once recognized. For much of the twentieth century, historians trained in European and American academic traditions tended to assume that urban life in sub-Saharan Africa began only with the arrival of Islamic traders or European colonizers. Archaeological research conducted since the 1970s, particularly along the middle Niger River, has overturned this assumption decisively.

The clearest and most thoroughly studied example is Jenné-Jeno, located near the modern city of Djenné in Mali. Excavations beginning in the 1970s revealed that the settlement grew gradually from a small village around 250 BCE into an urban center covering tens of hectares by the middle of the first millennium CE, with associated satellite settlements forming a larger urban cluster. The population engaged in farming, fishing, and herding to sustain itself, while also developing specialized iron production, pottery manufacture, and participation in long-distance trade networks that brought copper, possibly originating from sources hundreds of kilometers away, into the settlement.

What makes Jenné-Jeno especially significant to historians is what archaeologists did not find: no royal palace, no monumental architecture clearly associated with a single ruling family, and no clear evidence of a centralized political hierarchy controlling the settlement from a single point. This has led many archaeologists to describe early Jenné-Jeno as an example of what is sometimes called a "heterarchical" urban community — one in which power and authority were distributed across multiple institutions, lineage groups, craft associations, and ritual specialists, rather than concentrated in a single ruling office. This pattern challenges assumptions, drawn largely from the history of ancient Mesopotamia, Egypt, and other early urban civilizations, that cities necessarily require centralized monarchies to organize and sustain them.

Cities also grew in the Nile Valley, where Egyptian and Nubian urban centers developed in close connection with centralized monarchies, as discussed in Chapters 7 and 8. Along the East African coast, settlements that would later become the great Swahili trading towns began as smaller fishing and farming communities that grew increasingly urban as their participation in Indian Ocean trade expanded, a process examined more fully in Chapter 32. In the Horn of Africa, the kingdom of Aksum developed urban centers connected to its control of Red Sea trade routes, as discussed in Chapter 10. In southern Africa, the rise of Mapungubwe, examined in Chapter 38, shows yet another regional pattern of urban growth tied to cattle wealth, trade in ivory and gold, and the development of social hierarchy.

What unites these diverse regional stories is not a single cause but a shared set of underlying conditions: agricultural or pastoral surplus sufficient to support non-farming specialists, access to valuable trade goods or strategic trade routes, and social mechanisms — whether centralized monarchy, distributed lineage authority, or some combination — capable of organizing collective life at a larger and more complex scale than village society required. Understanding African urbanization, in other words, requires attention to multiple regional pathways rather than a single universal model.

Trade as a Force of Change

Trade was one of the most powerful forces reshaping African societies during this period, and its effects extended far beyond the simple exchange of goods. Trade reorganized settlement patterns, as communities positioned at advantageous points along trade routes grew disproportionately compared to those without such access. Trade reorganized social structure, as successful traders accumulated wealth and influence that could rival or exceed that of hereditary leaders. And trade reorganized political authority, as the ability to control, tax, or facilitate trade became an increasingly important source of power.

Several distinct types of trade operated across ancient Africa, often simultaneously. Local exchange connected nearby communities producing different but complementary goods — grain for fish, pottery for iron tools, salt for foodstuffs. Regional exchange connected communities across larger distances within a shared ecological or cultural zone, such as the trade linking different settlements along the Niger River floodplain. Long-distance trade connected communities across major ecological boundaries — the Sahara desert, the East African coast and the Indian Ocean, the southern African interior and its coastal outlets — often through networks of intermediary traders who each handled only one segment of a much longer route.

This last form, sometimes called relay trade, deserves particular attention because it shows how goods could travel enormous distances without any single trader or community controlling the entire route. Gold mined in the forests of West Africa might pass through the hands of several different groups of traders before reaching North African markets; cowrie shells originating in the Indian Ocean might pass through multiple intermediary communities before reaching West Africa, sometimes traveling thousands of kilometers from their point of origin. No single community needed to know the full extent of the network in which it participated for that network to function and to transform societies along its length.

Trade goods themselves reveal a great deal about the scale and reach of these networks. Archaeologists working at Jenné-Jeno found evidence of copper that likely originated from sources in the southern Sahara or beyond, suggesting trade connections extending well over a thousand kilometers even before the classic era of trans-Saharan caravan trade examined in Chapter 20. Glass beads, often originating from distant manufacturing centers in Egypt, the Mediterranean world, or later from Islamic and even Asian sources, appear at archaeological sites across the continent, demonstrating connections that crossed major ecological and cultural boundaries.

Trade did not simply move goods; it also moved ideas, technologies, religious practices, and people. Traders carried not only merchandise but also news, political information, religious beliefs, and cultural practices from one community to another. The spread of Islam along trans-Saharan and Indian Ocean trade routes, examined in Chapter 27, is one of the clearest examples of how commercial networks became channels for much broader processes of cultural and religious change.

Markets and Specialization

As trade intensified, African communities developed increasingly organized institutions for conducting exchange. Periodic markets, held on a regular schedule — weekly, biweekly, or according to other local calendars — became central institutions of economic and social life across much of the continent. Markets brought together farmers selling agricultural surplus, craftspeople selling manufactured goods, herders selling livestock and animal products, and long-distance traders selling goods obtained from distant regions. They also served important social functions beyond commerce: markets were places to exchange news, arrange marriages, resolve disputes, and maintain social ties across communities that might otherwise have little regular contact.

Craft specialization developed alongside market institutions, as growing population density and trade opportunity made it possible for some individuals to dedicate themselves primarily or entirely to specialized production rather than farming. Ironworkers occupied a particularly significant position in many African societies. Iron production required specialized technical knowledge, access to ore and fuel resources, and often ritual knowledge believed necessary to successfully transform raw ore into usable metal. In many West African societies, blacksmiths formed endogamous social groups — meaning they generally married within their own occupational community — and were often viewed with a combination of respect and wariness, seen as possessing powerful and somewhat dangerous knowledge.

Potters, too, developed specialized traditions, often producing distinctive styles that allow archaeologists today to trace trade connections and cultural influence across different regions and time periods by comparing pottery styles found at different sites. Textile production, leatherworking, woodworking, and the production of beads and ornaments from shell, stone, and metal all developed as specialized crafts in various regions, each requiring particular technical skills passed down through specific families, lineages, or apprenticeship traditions.

This growing occupational diversity had significant social consequences. In societies that had previously organized status primarily through kinship and age, occupation became an increasingly important additional axis of social identity and sometimes social hierarchy. Specialized craftspeople, traders, and religious specialists formed social groups whose status depended not on lineage alone but on skill, wealth, ritual knowledge, or control of valuable resources and connections. This did not eliminate kinship as an organizing principle of African social life — kinship remained centrally important — but it added new and increasingly significant dimensions of social differentiation.

Political Authority and Urban Life

One of the most important lessons of early African urban history is that cities did not require centralized monarchical authority in order to function, grow, and persist for centuries. As discussed in Section 11.1, Jenné-Jeno appears to have sustained urban life for well over a thousand years without clear evidence of a single dominant ruling institution. This does not mean that Jenné-Jeno had no political organization at all; rather, it suggests that authority may have been distributed across multiple institutions — lineage heads, craft associations, ritual specialists, and perhaps councils of elders or notable families — that cooperated, negotiated, and sometimes competed with one another to manage the collective affairs of the urban community.

This pattern, sometimes described by archaeologists as heterarchy, stands in contrast to the more familiar pattern of centralized, hierarchical political authority that characterized ancient Egypt, examined in Chapter 7, and that would later characterize large African states such as Ghana, Mali, and Songhai, examined in Chapters 20 through 23. Both patterns appear across African history, sometimes within the same region at different periods, and sometimes within the same period in neighboring regions. Understanding this diversity is essential to avoiding the assumption that all complex societies must follow a single model of political organization.

Where centralized authority did develop, several factors appear to have been particularly important. Control of trade — the ability to tax caravans, regulate market access, or monopolize particularly valuable goods such as gold or salt — provided rulers with revenue and leverage that could be converted into political power. Control of specialized production, particularly of iron tools and weapons, gave some rulers military and economic advantages over rivals. Religious legitimacy, examined further in Section 11.6, provided rulers with spiritual authority that complemented and reinforced their political and economic power. And the ability to organize defense against rival communities or external threats gave rulers practical justification for concentrating authority and resources.

The relationship between urbanization and centralized state formation was neither automatic nor uniform. Some cities, like early Jenné-Jeno, sustained themselves for centuries without developing strong centralized rulership. Others, like the early urban centers that would eventually form the core of the Ghana Empire examined in Chapter 20, developed increasingly centralized political authority over time, often in response to the opportunities and pressures created by long-distance trade. Still others combined urban growth with the consolidation of monarchical power from a very early stage, as in ancient Egypt. This variation is itself an important historical lesson: state formation in Africa, as elsewhere, followed multiple distinct pathways shaped by local geography, economy, and social structure.

Craft Production and Wealth

Craft production was not only a matter of meeting practical needs for tools, containers, and clothing; it was also a major engine of wealth accumulation and social differentiation in early African cities. Iron tools dramatically improved agricultural productivity, allowing farmers to clear land, till soil, and harvest crops more efficiently than with earlier stone or wood implements. Iron weapons provided significant military advantages to communities that possessed them over those that did not. Control of iron production and trade, therefore, could translate directly into economic and political power.

Gold, although primarily associated in many historical accounts with the later Sahelian empires examined in Chapters 20 through 23, was already being mined and traded in West Africa during the period covered in this chapter, moving through regional and long-distance networks well before the classic age of trans-Saharan gold trade. Textile production, particularly the weaving of cotton in regions where it could be cultivated, created valuable manufactured goods that could be traded across considerable distances. Salt, essential for human and animal health and often scarce in regions far from the sea or from inland salt deposits, became one of the most consistently valuable trade goods across the continent, exchanged in some regions for quantities of gold approaching its own weight.

The accumulation of wealth through craft production and trade had significant social consequences. Successful traders and craftspeople could acquire wealth that allowed them to support larger households, sponsor religious ceremonies, contribute to community defense, and in some cases challenge or supplement the authority of hereditary leaders. This created new forms of social mobility — opportunities for individuals and families to improve their social position through trade and craft success rather than through birth alone — even as it also created new forms of inequality between successful traders and craftspeople and those who remained primarily engaged in subsistence agriculture.

Ritual Centers and Sacred Space

Religion and ritual practice played a central role in the growth of many early African settlements. In numerous regions, permanent settlements first developed not primarily as economic or defensive centers but as sites of religious significance — locations associated with powerful ancestral spirits, important burial grounds, or sites believed to possess particular spiritual potency. Pilgrims, worshippers, and those seeking ritual services at these sites created demand for food, lodging, and craft goods that could, over time, support the growth of permanent resident populations of farmers, craftspeople, and religious specialists.

Religious authority and political authority were often closely intertwined in these emerging urban centers. Religious specialists — priests, diviners, ritual leaders — frequently played important roles in organizing communal labor, resolving disputes, and legitimizing the authority of political leaders. In some societies, political rulers were themselves understood to possess sacred or semi-divine status, a pattern examined in greater depth in Chapter 26's discussion of sacred kingship. In others, religious and political authority remained more clearly distinguished, with religious specialists serving an advisory or legitimizing function alongside, rather than merged with, political leadership.

Sacred sites also served important functions in organizing space within growing urban centers. Shrines, burial grounds, and ceremonial spaces often occupied prominent locations within or near settlements, serving as focal points for community identity and collective ritual practice. The maintenance of these sacred spaces required organized labor and resources, providing yet another mechanism through which growing urban communities developed institutions for coordinating collective action beyond the scale of individual households or lineages.

Regional Networks and Exchange

Early African cities did not develop in isolation from one another. Across river valleys, savanna regions, and coastal zones, networks of interconnected settlements developed, linked by trade, shared culture, and sometimes political alliance or rivalry. Along the middle Niger River, Jenné-Jeno was part of a larger cluster of settlements, some specializing in particular crafts or agricultural products, others serving primarily as trade and transit points, together forming an integrated regional economy.

These regional networks often displayed a kind of settlement hierarchy, with larger urban centers serving as hubs for trade, craft production, and political or religious authority, surrounded by smaller towns and villages that supplied agricultural goods, raw materials, and labor while also drawing on the larger centers for access to specialized goods, markets, and services unavailable locally. This hierarchical pattern of settlement, in which different communities played complementary economic and social roles within a larger regional system, appears across multiple regions of ancient Africa, from the Niger River valley to the Nile Valley to the East African coast.

Regional networks also connected different ecological and cultural zones to one another, creating economic interdependence across considerable distances. The trade connecting the Sahara desert's salt-producing regions with the Sahel's grain-producing regions and the forest zone's gold- and kola-producing regions, examined further in Chapter 17, exemplifies this pattern: each zone produced goods the others lacked, creating powerful economic incentives for sustained exchange and, eventually, for the development of more formal political and commercial institutions to manage that exchange.

Urbanization and State Power

The relationship between cities and states is one of the central analytical questions of this chapter. Urbanization — the growth of dense, permanent settlements with specialized, non-agricultural populations — and state formation — the development of centralized political institutions capable of exercising authority over a defined territory and population — are related but distinct historical processes. Cities can exist without strong centralized states, as the example of early Jenné-Jeno demonstrates. States can exercise authority over largely rural populations without necessarily possessing large urban capitals, particularly in early stages of state formation.

Over time, however, cities and states tended to become increasingly intertwined across most regions of Africa. Cities provided concentrated populations of craftspeople, traders, and resources that ambitious political leaders could draw upon to build military and administrative capacity. States, in turn, often provided the security, infrastructure, and economic regulation that allowed cities to grow larger and trade more extensively than they could under conditions of political fragmentation or insecurity. The growth of organized states along the Niger River, in the Lake Chad basin, along the East African coast, and in southern Africa, examined in later chapters of this textbook, built directly on the patterns of urbanization, trade, and craft specialization described in this chapter.

This relationship was not simply one-directional, with cities producing states. In some cases, the establishment of centralized political authority preceded and actively promoted urban growth, as ambitious rulers established new capitals, encouraged the settlement of craftspeople and traders, and used military or diplomatic power to secure and expand access to valuable trade routes. The interaction between urban economic growth and state political consolidation was, in most regions, a mutually reinforcing process rather than a simple one-way sequence.

Early African Cities in Comparison

Placing early African urbanization in comparative perspective helps clarify both its distinctive features and its connections to broader patterns of human history. Cities first developed in human history in Mesopotamia, beginning around 3500 BCE, in close association with intensive irrigation agriculture, written record-keeping, and centralized temple- and palace-based political authority. The Indus Valley civilization, flourishing from roughly 2600 to 1900 BCE, developed remarkably large and well-planned cities with sophisticated water and sanitation systems, though with less obvious evidence of centralized monarchy than Mesopotamia. Early Chinese urban centers along the Yellow River developed in association with both agricultural surplus and centralized dynastic authority.

Ancient Egypt, examined in Chapter 7, developed urban centers in close connection with one of history's most thoroughly centralized monarchies, fitting more closely the Mesopotamian pattern of city and centralized state developing together. Jenné-Jeno and other early West African urban centers, by contrast, more closely resemble the Indus Valley pattern: substantial, long-lasting urban populations without clear evidence of strong centralized monarchical control, suggesting that complex urban society and centralized political hierarchy, while often associated with one another, are not the same thing and do not necessarily require one another.

This comparison matters historically for a specific reason: for much of the twentieth century, many historians working from primarily European and Middle Eastern evidence assumed that "civilization," urbanization, and centralized statehood were essentially the same package, arriving together or not at all. The archaeological evidence from West Africa, alongside comparable evidence from other world regions, demonstrates that this assumption is mistaken. Complex urban life could and did develop through multiple distinct institutional pathways, and sub-Saharan Africa's early urban history deserves recognition as an independent and significant chapter in the global history of cities, not as a delayed or incomplete imitation of patterns established elsewhere.

Chapter Review and Urban Origins Checkpoint

This chapter has examined how cities, markets, and organized states first developed across ancient Africa, emphasizing the diversity of regional pathways and the importance of trade, craft specialization, and religious life in shaping early urban communities. Before moving to the chapters that follow, students should be able to demonstrate understanding of these foundational concepts.

The central insights of this chapter are: cities developed independently across multiple regions of ancient Africa, often centuries before substantial outside contact. Trade was a powerful force reshaping settlement patterns, social structure, and political authority. Craft specialization, particularly in ironworking, created new forms of wealth, status, and occupational identity. Political authority in early cities took multiple forms, including centralized monarchy and distributed, heterarchical authority shared among multiple institutions. Religious and ritual life often played a foundational role in the growth of permanent settlements. Regional trade networks connected cities to one another and to distant ecological zones. Urbanization and state formation were related but distinct processes that interacted differently in different regions. And the history of early African cities deserves recognition as an independent and historically significant chapter in the global history of urban civilization.
