Traders from the Middle East and the Mediterranean had been doing business in the Sahara, after the introduction of camels, from about 2,000 years ago, notably trading the vast resources of salt there; but it wasn’t until the Arab conquests of the seventh century CE that the scene was set for a push southward. By the ninth century they had crossed the Sahara, and by the eleventh were firmly established as far south as modern-day Nigeria. The Arabs were also coming down the east coast and establishing themselves in places such as Zanzibar and Dar es Salaam in what is now Tanzania.
When the Europeans finally made it down the west coast in the fifteenth century they found few natural harbours for their ships. Unlike Europe or North America, where the jagged coastlines give rise to deep natural harbours, much of the African coastline is smooth. And once they did make land they struggled to penetrate any further inland than about 100 miles due to the difficulty of navigating the rivers, as well as the challenges of the climate and disease.
Both the Arabs and then the Europeans brought with them new technology which they mostly kept to themselves, and took away whatever they found of value, which was mainly natural resources and people.
Slavery existed long before the outside world returned to where it had originated. Traders in the Sahel region used thousands of slaves to transport vast quantities of the region’s then most valuable commodity, salt, but the Arabs began the practice of subcontracting African slave-taking to willing tribal leaders who would deliver them to the coast. By the time of the peak of the Ottoman Empire in the fifteenth and sixteenth centuries hundreds of thousands of Africans (mostly from the Sudan region) had been taken to Istanbul, Cairo, Damascus and across the Arabian world. The Europeans followed suit, outdoing the Arabs and Turks in their appetite for, and mistreatment of, the people brought to the slave ships anchored off the west coast.
Back in the great capital cities of London, Paris, Brussels and Lisbon, the Europeans then took maps of the contours of Africa’s geography and drew lines on them – or, to take a more aggressive approach, lies. In between these lines they wrote words such as Middle Congo or Upper Volta and called them countries. These lines were more about how far which power’s explorers, military forces and businessmen had advanced on the map than what the people living between the lines felt themselves to be, or how they wanted to organise themselves. Many Africans are now partially the prisoners of the political geography the Europeans made, and of the natural barriers to progression with which nature endowed them. From this they are making a modern home and, in some cases, vibrant, connected economies.
