Economy, Craft and Trade
Farming, iron, cloth and glass; the market system and the women who ran it; cowrie money; and the routes that tied Yorubaland to the Sahara and the Atlantic.
The Yoruba economy before the twentieth century rested on farming, but what made it distinctive was the density of its towns and the sophistication of the exchange system that fed them. Yorubaland was among the most urbanised regions in precolonial Africa, with large populations living in walled towns and farming outward from them, which requires a functioning system for moving food, craft goods and money at scale. That system was the market network, it ran on a fixed cycle, it used an imported shell currency, and it was operated in very large part by women who held formal titled authority over it.
Two structural facts shape everything else. First, Yorubaland sits between the savanna and the coast, so it is positioned to broker between the trans-Saharan trade system to the north and the Atlantic system to the south, and its commercial history is largely the history of that intermediary position. Second, the currency was imported and the region did not control its supply, which made the whole economy vulnerable to monetary shocks originating thousands of kilometres away. Both facts cut both ways, and both matter for understanding the nineteenth century.
Agriculture
The base was yam, in the forest and forest margin, with maize arriving from the Americas and becoming important, alongside cocoyam, cowpea, plantain, and later cassava, which spread widely in the nineteenth and twentieth centuries. Oil palm grew semi-wild and was managed rather than planted in the early period. Kola, principally Cola nitida and Cola acuminata, was a major export crop because it was in demand across the Muslim savanna and Sahel where it was one of the few permitted stimulants.
Farming was organised through the lineage, with land held by lineages and allocated to members rather than bought and sold, and worked by household labour supplemented in the larger farms by ẹrú, people in various conditions of servitude, and by ọwẹ̀, reciprocal work-party labour where a farmer feeds and entertains a group who work his land and he theirs in turn. The distinction between these is important and often collapsed in colonial-era descriptions.
Farm and town were separate. Yoruba farmers lived in the town and travelled to the farm, often staying at farm hamlets, àbà, during intensive periods. This is the material fact underneath Yoruba urbanism: a town of tens of thousands supported by an agricultural hinterland worked by its own residents.
Iron
Iron smelting and forging in West Africa are old, with evidence associated with the Nok culture as early as the mid first millennium BCE . Yoruboid speakers developed ironworking early, before the wide use of copper alloys . This sequence matters for the popular framing of Ifẹ̀'s bronzes as an isolated marvel: the metallurgical foundation was already deep, and the copper-alloy tradition sat on top of a long-established iron industry.
Iron underwrote agriculture through hoes, cutlasses and axes, and it underwrote war. It also carried religious weight. Ògún, the òrìṣà of iron, is the patron of smiths, hunters, warriors and now of drivers and mechanics, and the oath sworn on iron is still legally recognised in Nigerian courts as an alternative to the Bible or Quran. That continuity from smelting technology to legal practice is a good indication of how central the metal was.
Smelting was a specialised, often lineage-held, craft, and smelting sites were typically sited away from settlements near ore and charcoal wood. Local smelting declined sharply in the nineteenth and early twentieth centuries as imported European bar iron became cheaper, and the smiths survived while the smelters did not.
Cloth
Yoruba weaving runs on two distinct loom traditions distinguished by gender. Men weave on a horizontal narrow-strip loom producing strips roughly 10 to 20 centimetres wide and variable in length, which are then sewn edge to edge into a full cloth; women weave on a vertical broadloom producing wider single pieces . Both are indigenous, and the narrow-strip tradition is the more famous.
Aṣọ òkè, literally top cloth or cloth from up-country, is the prestige narrow-strip fabric, traditionally traced to weaving centres including Iṣẹ́yìn, Ọ̀yọ́ and Ẹdẹ, with origins conventionally placed around the fifteenth century . Three classical prestige cloths dominated into the early twentieth century: etù, a deep indigo so dark it reads as black; sányán, woven from the beige silk of the Anaphe moth and the most valued; and àlàárì, a deep red from imported magenta waste silk unravelled and rewoven . Aṣọ òkè is worked into the agbádá and fìlà for men and the ìró, bùbá and gèlè for women . The àlàárì case is instructive: the prestige cloth of the Yoruba interior depended on an imported fibre, which is a small illustration of how connected this economy was.
Àdìrẹ is the resist-dyed indigo cloth tradition, worked by women, using stitch resist, tied resist and cassava-paste stencil resist. Its major centres were Abẹ́òkúta and Ìbàdàn. Indigo, ẹlú, was locally grown and processed, and dyeing was a women's craft with its own guild organisation.
Glass and beads
Ilé-Ifẹ̀ was a primary glass producer, making glass from raw materials rather than remelting imports, in the early second millennium CE. Excavations at Igbo Olókun recovered over 12,000 glass beads and hundreds of glass-encrusted crucible fragments, and the glass carries a high-lime, high-alumina signature, roughly 10 to 20 percent alumina and 12 to 20 percent lime, unknown in European, Middle Eastern or Asian glass and traceable to local high-alumina pegmatite sand combined with lime from snail shell . Ifẹ̀ beads circulated widely in West Africa. This is the clearest single piece of evidence for Yoruba manufacturing for export, and it is chemical rather than inferential.
The market system
Yoruba markets ran on a fixed cycle, most commonly of four or eight days, with neighbouring towns staggered so that traders could circulate between them. Every town of consequence had a central market, ọjà, typically sited at the palace forecourt, which places commerce physically and symbolically at the centre of political authority. Night markets, ọjà alẹ́, were a normal feature.
The word ọjà carries enough weight in Yoruba thought to appear in the most-quoted proverb about human life.
Ayé lọjà, ọ̀run nilé.
World / is-market, heaven / is-house.
The world is a marketplace, the otherworld is home.
Translator: rendered here from the transcribed Yoruba; this is a very widely circulated proverb and appears in many published collections. The rendering is my own and should be treated as medium confidence rather than as a specific scholar's translation.
The force of the proverb depends on knowing what a Yoruba market is: a place you go to, transact in, and leave, crowded and temporary, not a place of residence. Ilé is the compound, the lineage house, the permanent seat and the place of the ancestors. So the line is saying that earthly life is a trading trip and ọ̀run is where you actually live. English can carry that with a gloss but not in five words. Note also what the proverb assumes about its audience: that the market is the most immediately understandable image of transient, purposeful, crowded activity available to anyone. That is a statement about how central markets were.
Women and the authority over trade
Yoruba women dominated market trading, and their control was formalised in title. The Ìyálọ́jà, mother of the market, held authority over a market and its traders. The Ìyálóde, a title whose literal sense is mother in charge of external or public affairs and which is sometimes glossed as king of the women, was a chieftaincy held by a woman with oversight of women's trade guilds and marketplaces, and with a seat in the town's council . The Ìyálóde was elected on merit and standing rather than inherited .
This was not honorific. The Ìyálóde coordinated the economic activity that formed the basis of local and long-distance commerce, adjudicated disputes among traders, set market rules, and represented women's interests to the ọba and chiefs . Efúnṣetán Aníwúrà, the second Ìyálóde of Ìbàdàn, built one of the largest fortunes in nineteenth-century Yorubaland through long-distance trade in agricultural produce, tobacco and enslaved people, and commanded a substantial armed following of her own . Her career is a corrective in two directions at once: it shows the scale of authority a woman could hold, and it shows that women of standing participated in the slave trade as principals.
The dual-sex character of the system is real and should be stated precisely: Yoruba political organisation had parallel male and female title hierarchies with women holding genuine institutional authority, particularly over commerce. It is also true that this authority was concentrated in specific offices rather than distributed generally, and that colonial administration systematically dismantled the women's side of it by dealing only with male chiefs. Oyèrónkẹ́ Oyěwùmí's argument that gender itself was not the primary organising category of precolonial Yoruba social relations is a further and more contested position; it is treated in the social section of this corpus rather than here.
Cowries
The currency was the cowrie shell, Monetaria moneta, and it is central to understanding this economy. Cowries were in use in the Yoruba and Benin regions early enough that seventeenth-century European merchants remarked on shell money as the established currency . Cowries have properties that make them good money in this setting: they are durable, roughly uniform, impossible to counterfeit, and divisible down to very small values, which suits an economy of many tiny market transactions.
They also have one fatal property. They do not occur in West Africa. They came from the Maldives, carried first through the Indian Ocean and trans-Saharan networks and later in bulk by European shipping directly to the coast. The money supply of the Yoruba economy was therefore controlled entirely outside it .
The consequence arrived in the nineteenth century. European traders shipped cowries in enormous and increasing quantities, and from the mid nineteenth century the introduction of the cheaper East African Monetaria annulus alongside steam shipping collapsed the cost of delivery. The result was severe and sustained inflation, with cowries losing most of their value against goods over a few decades. This monetary shock coincided with the wars, with the abolition of the Atlantic slave trade and with the transition to palm oil exports, and it is a badly under-recognised part of nineteenth-century Yoruba economic distress. Ogundiran's archaeological work in the Ìlàrè district and elsewhere uses beads and cowries as material evidence of exactly these Atlantic-era transformations in ordinary Yoruba domestic life .
Cowries were counted in strings and bags with standard denominations, and the arithmetic of large cowrie sums was itself a specialised skill. The Yoruba numeral system, which is subtractive and vigesimal, is closely tied to this counting practice.
The trade routes
Northward. Yorubaland exported kola, cloth and slaves north, and imported horses, salt, natron, leather, copper and brass, and North African and European goods that had crossed the Sahara. Ọ̀yọ́'s dependence on the northern horse supply, since horses could not be bred in the tsetse zone, made this route strategically essential to the empire . Ifẹ̀'s copper came south along the same system, with Takedda in the region of present Niger and Mali named as a source . The northern connection ran through Nupe, Borgu and Hausaland and linked into the trans-Saharan routes to North Africa.
Southward. The lagoon system running from Lagos east and west provided a protected inland waterway connecting the coastal ports to the interior via the rivers and portages. Ijẹ̀bú controlled the key corridor and enforced a monopoly requiring that all trade through its territory be handled by Ijẹ̀bú merchants . Exports south were, before abolition, principally people, and after abolition principally palm oil and palm kernels; imports were cowries, textiles, spirits, tobacco and firearms.
Internally. The market cycle moved goods between towns, and specialised long-distance traders, including women trading on a large scale, moved cloth, kola, salt, dried fish and craft products across the region.
The nineteenth-century transition
Three shocks landed in the same century. The Atlantic slave trade was suppressed by British naval action from 1808 onward, removing the largest single export earner from a region that had by then been shaped around it. The palm oil trade replaced it, and the typical Yoruba processing installation was the ẹkú, a large circular container built on an open rock surface . Palm oil was more labour-intensive and more widely distributed in its benefits than the slave trade, which changed who earned from export and gave women, who dominated oil processing and local trading, a larger role. And the cowrie inflation eroded the value of accumulated savings across the whole society.
The palm oil economy also increased internal slavery rather than reducing it, because oil production and the head-porterage that moved it to the coast were labour-hungry. This is the general West African pattern in the period, and Yorubaland fits it. Abolition of the external trade did not abolish slavery internally, and the nineteenth-century wars kept supplying captives to internal markets long after the Atlantic outlet was closing.
