For thousands of years, the oil palm – indigenous to West Africa – has had an intimate relationship with humans. An explosive expansion of oil palm groves throughout western and central Africa in the wake ofa dry period around 2,500 years agoenabled human migration and agricultural development; in turn, humans facilitated oil palm propagation through seed dispersal and slash-and-burn agriculture. Archaeological evidence shows that palm fruit and kernels and their oil already formed an integral part of West African diets5,000 years ago.

Oil palms were not only protected as a valuable crop, they also grew well in cleared and burned areas. Abandoned villages and farm camps often became prominent palm oil groves; even today the age and distribution of oil palms can help easily identify old settlements. With the exception of “royal” oil palm plantations, established in the 18th century for palm wine in the Kingdom of Dahomey, all of West Africa’s oil palms grew in such wild and semi-wild groves.

Women and children collected loose fruits from the ground, while young men harvested fruit bunches by climbing up to the top of the palms. The fruit was then processed into palm oil by women, through a time-consuming and labour-intensive process involving repetitively boiling and filtering the fresh fruits with water – similar methods are still largely used throughout West Africa. While pure red palm oil was derived from the palm fruit’s fleshy outer mesocarp, women also, often with the help of children, cracked the palm kernels to make brown, clear palm kernel oil.

Palm oil was, and remains, a key ingredient in West African cuisine, such as that of southern Nigeria: from the simple dish of boiled yam, palm oil andKanwa salt, toBanga soupmade from the mashed fruit left over during palm oil processing and many other “soups” eaten with pounded yam or garri (ground cassava).

Throughout West Africa, palm oil was also used in soap making; today Yoruba black Dudu-Osun soap is a trademark Nigerian brand. In Benin Kingdom, palm oil was used in street lamps and as a building material in the king’s palace walls. It also found hundreds of different ritualistic and medicinal uses, in particular as a skin ointment and a common antidote to poisons. In addition, the sap of oil palms was tapped for palm wine, and palm fronds provided material for roof thatching and brooms.

Early 19th-century boom

Palm oil has been known in Europe since the 15th century, but it was Liverpool and Bristol slave traders who, in the early 19th century, began larger-scale imports. They were familiar with its multiple uses in West Africa and had already been buying it regularly as food for slaves being shipped to the Americas. Through the slave trade the oil palm itself also came to Martinique, where it gained its official botanical record asElais Guineensis Jacq.in the French botanist Nikolaus Joseph von Jacquin’sSelectarum Stirpium Americanarum Historia(1763).

With theabolition of the slave tradeto the Americas in 1807, British West Africa traders turned to European markets and natural resources as commodities, in particular palm oil. At the time, the main sources of fats and oils in northern Europe were animal-based: tallow, lard, whale and fish oils – products for which it could be a challenge to secure regular supplies. There was therefore a ready market for palm oil, which, as the historian Martin Lynn puts it, came to “grease the wheels of the industrial revolution” in the early 19th century.

Palm oil was used as an industrial lubricant, in tin-plate production, street-lighting, and as the fatty semi-solid for candle making and soap production. Breakthroughs in chemistry, in particular Michel Eugène Chevreul’s discovery in 1823 that oils and fats were compounds of fatty acids and glycerine, facilitated a change to large-scale, industrial soap production. After a new technique for bleaching red palm oil (and reducing its distinct smell) was discovered in 1836 and duty on palm oil was abolished by the British government in 1845, it became a particularly attractive ingredient to soap makers, one that moreover was delivered straight into the ports of the main soap-making areas.

Ever larger quantities of palm oil – increasing from 157 metric tonnes per year in the late 1790s to 32,480 tonnes by the early 1850s – were brought to the United Kingdom by small-scale West Africa traders such as John Johnson Hamilton, who came to be known as “palm oil ruffians”. The trade was not for the faint-hearted. Once a year, traders – often younger employees who had to cut their teeth – would spend up to six weeks travelling in small schooners to one of the many trading stations on the West African coast. There were several dozen trading stations in the Oil Rivers area of today’s Niger Delta – the heartland of the West African palm oil trade.

European traders lived and traded entirely on hulks – former, abandoned sailing ships. This was partly to try and avoid deadly diseases such as malaria and yellow fever, but also because local authorities did not permit them to build on land. Inland trade was controlled tightly by local brokers and village chiefs. European traders gave these brokers European goods such as cooking utensils, salt and cloth “on trust” so they would buy palm oil from inland areas of production. Then the traders waited on board their ships for them to return, sometimes for months at a time. Many of the African brokers were themselves former slave traders – the slave trade in the Niger Delta did not immediately stop with abolition but continued alongside the palm tradeuntil the 1840s. Palm brokers continued to use the same network and brokerage system developed for the slave trade, and European traders had to follow suite.

Whilst waiting, the European traders’ coopers would assemble large casks (bought en route in pieces from French wine-barrel makers) to hold palm oil, and there was some small-scale buying of palm oil from local people. Otherwise there was little to do, and in the tedium of the long season in West Africa, drinking, gambling and violence were all too common, occasionally resulting in casualties.

Unlike the large industrial concessions that were later established in Southeast Asia, it was largely West Africa’s existing wild and semi-wild groves that furnished European demand. In the hinterland of the Oil Rivers and many other areas, there was an abundance of wild oil palm that could be harvested. Some planting did take place; the Krobo in southeastern Ghana, where fewer oil palms were growing naturally, began systematic cultivation in response to European demand.

In Dahomey, too, more plantations were set up, and generally oil palms became increasingly prioritised under community land management strategies. Some parts of southeastern Nigeria focused so much on the production of palm oil that they became completely reliant on yam imports from further north. However, there was no large-scale, radical transformation in land management, ownership or ecology.

The rise in oil palm brokers

West African producers successfully responded to growing European palm oil demand through the gradual modification and expansion of existing small-scale production methods. This brought more income to female producers, especially in the first few decades. But because palm oil continued becoming ever more important as an export (and source of income), its production and trade involved more and more men.

Young men did the dangerous work of harvesting fresh fruit bunches, with increasing specialisation. In the Benin Kingdom, Urhobo men were hired due to their long history of palm oil production and trade. In palm oil processing itself, a second, far less labour-intensive method developed, where fresh fruit were left to ferment and then stamped on in large pits dug in the ground, or sometimes in old canoes. The resulting oil was much dirtier, harder (due to its much higher free fatty acids content) and inedible. It also fetched lower prices, but the new technique enabled much larger-scale production than before. This stamping was often done by young men, hired labourers or even slaves.

There was plenty of work in transporting palm oil, carrying calabashes filled with oil along forest paths to the nearest river and working on canoes. This brought some cash income for young men, but it was generally older, already wealthier men, and in particular chiefs, who were able to profit most from “red gold”, through the labour of their wives and slaves and from control of trade. It was through brokerage that most wealth and power could be gained, and local power structures were deeply enmeshed with trade in palm oil.

A particularly powerful broker at this time was William Dappa Pepple, the amanyanabo (king) of Bonny (in today’s southeastern Nigeria) from 1837 to 1854, who used the “canoe house” system to expand his oil palm trading networks with inland regions. Originally buildings containing large war canoes, canoe houses had become the basis for political allegiances in Bonny during the slave trade. The system also enabled the absorption of slaves into the lineage, and some themselves became powerful and rich brokers, such as King Jaja of Opobo.

Colonial takeover

In the late 19th century, chemists discovered that hydrogenation could be used to process vegetable oils (liquid unsaturated fats) into margarine (solid saturated fats), and margarine played an increasingly important role in supplying fats for the diet of Europe’s growing urban working class. While the volume of imports of West African palm oil into the UK levelled off between the 1850s and 1890s, large-scale production of this new edible product stimulated renewed demand for palm oil and especially kernels in the early 20th century; in the 1930s, British West Africa exported around 500,000 tonnes of palm produce annually. Palm produce continued to play a significant role in West African rural economies, but local control of the trade eroded under colonial administration; the opportunities for wealth and power palm oil had offered local people (as well as palm oil ruffians) were no longer available. Moreover, as the colonial powers continued expanding their reach elsewhere in the tropics, a game-changing development was slowly beginning: the rise of the oil palm plantation. Within a few short decades, expanses of Southeast Asian forest had been cleared, creating a fast track to industrial-scale monoculture plantations, thus ending West Africa’s position as the global hub of palm oil production.
