History of Technology, Industry, and Trade in West Africa

The Impact of the Iron Revolution and Mineral Wealth in West Africa

The advent of the iron revolution brought about a significant transformation in the nature of warfare and social structure within West African societies. New fighting weapons, including short and long spears and iron rods, replaced earlier implements made of stone and bronze, such as clubs and sticks. These iron weapons were drastically superior in efficacy, allowing the first societies that obtained them to conquer and dominate those without similar technology. Through this process of conquest, political authority was established over neighboring groups, which simultaneously facilitated the transfer of iron-working technology to the conquered peoples. Furthermore, the burgeoning knowledge regarding the mining and utilization of metals spurred the expansion of the gold and ivory trade. These metals were highly sought after not only by people within West Africa but also by traders from North Africa and Europe.

Arts, Crafts, and Industrial Organization

From time immemorial, the primary occupations of West African peoples were centered on subsistence activities such as farming, hunting, and fishing, which provided essential food, shelter, and clothing. Over time, agricultural productivity increased, resulting in a surplus of food that could be exchanged for non-indigenous goods. This surplus allowed individuals the freedom to pursue specialized local industries. These industries encompassed a wide variety of crafts, including salt refinery, fish-making, soap-making, cloth weaving, leather works, and the crafting of gold, ivory, copper, iron, and earth works. These industries were typically organized on a small scale, where the unit of production consisted of a master craftsman and his apprentice.

Spatial organization within towns and marketplaces was defined by trade, as those practicing the same craft stayed in close proximity to one another. Consequently, metal workers would cluster in one specific area, while weavers would occupy another. Each specific trade was overseen by an appointed head who supervised the craftsmen. In many instances, this head served a dual role as the works' chief priest; for example, iron workers might be led by the Ogun Chief priest.

The Evolution of Internal Trade and Market Systems

Internal trade in West Africa originated at the village level following the neolithic revolution, where inhabitants began exchanging goods among themselves. As social contacts expanded, humans began to exchange goods with neighboring villages, a process aided by the establishment of fixed marketplaces and specific market days. Certain villages grew into significant commercial centers if they possessed a strategic geographic site, an abundant supply of a desirable product, or a powerful army. During these early stages, the primary mode of exchange was the barter system.

Trade Dynamics in the Forest Zone

Trade within the forest zone occurred between villages located in both the forest and Savannah regions. However, this trade was characterized by a smaller volume and limited geographic scope compared to other regions. These limitations were primarily imposed by the physical difficulties of traveling through the forest. Because animals of burden could not survive in the forest environment, goods had to be transported via human porterage, which strictly limited the quantity of goods that could be moved at any one time.

Local Trade and Commodity Specialization

Local trade within the forest zone was conducted between neighboring villages that specialized in specific commodities. This specialization allowed villages to exchange their unique products for those they lacked. For instance, communities situated along major rivers would provide fish and salt to inland villages in exchange for agricultural staples like yams or beans. This level of trade was uncomplicated and did not involve professional traders; it relied entirely on the barter of agricultural products or iron tools and weapons, such as knives, cutlasses, axes, hoes, and spears. Marketplaces and scheduled market days were developed in every locality to facilitate these exchanges.

Export Trade and Professionalization

Export trade in the forest zone was far more extensive than local trade, involving the movement of goods over distances of 100100s of miles between different tribes and villages. Salt, a rare and essential commodity produced by coastal communities, was a major export to the hinterland. Conversely, those living in the northern reaches of the forest zone exported kola nuts to Sudanese states. In exchange for coastal salt and fish, hinterland communities exported palm-oil, soap manufactured from palm-oil, iron wares, yams, plantains, and slaves.

The organization of export trade was considerably more complex than local trade due to the long distances involved. Traders utilized specific bushpaths or river routes, traveling for several days on foot or in canoes. This demanding logistical requirement led to the emergence of a specialized class of people who dedicated themselves entirely to the import and export trade, marking a shift from casual exchange to professional commerce.
