) gives some sense of the scale of the slave trade. Using modern country boundaries, it depicts estimates of the cumulative extent of slavery between 1400 and 1900 as a percent of population
in 1400. Darker colors show more intense slavery. For example, in Angola, Benin, Ghana, and Togo, total cumulative slave exports amounted to more than the entire population of the country in 1400.

The sudden appearance of Europeans all around the coast of Western and Central Africa eager to buy slaves could not but have a transformative impact on African societies. Most slaves who were shipped to the Americas were war captives subsequently transported to the coast. The increase in warfare was fueled by huge imports of guns and ammunition, which the Europeans exchanged for slaves. By 1730 about 180,000 guns were being imported every year just along the West African coast, and between 1750 and the early nineteenth century, the British alone sold between 283,000 and 394,000 guns a year. Between 1750 and 1807, the British sold an extraordinary 22,000 tons of gunpowder, making an average of about 384,000 kilograms annually, along with 91,000 kilograms of lead per year. Farther to the south, the trade was just as vigorous. On the Loango coast, north of the Kingdom of Kongo, Europeans sold about 50,000 guns a year.

All this warfare and conflict not only caused major loss of life and human suffering but also put in motion a particular path of institutional development in Africa. Before the early modern era, African societies were less centralized politically than those of Eurasia. Most polities were small scale, with tribal chiefs and perhaps kings controlling land and resources. Many, as we showed with Somalia, had no structure of hierarchical political authority at all. The slave trade initiated two adverse political processes. First, many polities initially became more absolutist, organized around a single objective: to enslave and sell others to European slavers. Second, as a consequence but, paradoxically, in opposition to the first process, warring and slaving ultimately destroyed whatever order and legitimate state authority existed in sub-Saharan Africa. Apart from warfare, slaves were also kidnapped and captured by small-scale raiding. The law also became a tool of enslavement. No matter what crime you committed, the penalty was slavery. The English merchant Francis Moore observed the consequences of this along the Senegambia coast of West Africa in the 1730s:

Institutions, even religious ones, became perverted by the desire to capture and sell slaves. One example is the famous oracle at Arochukwa,
in eastern Nigeria. The oracle was widely believed to speak for a prominent deity in the region respected by the major local ethnic groups, the Ijaw, the Ibibio, and the Igbo. The oracle was approached to settle disputes and adjudicate on disagreements. Plaintiffs who traveled to Arochukwa to face the oracle had to descend from the town into a gorge of the Cross River, where the oracle was housed in a tall cave, the front of which was lined with human skulls. The priests of the oracle, in league with the Aro slavers and merchants, would dispense the decision of the oracle. Often this involved people being “swallowed” by the oracle, which actually meant that once they had passed through the cave, they were led away down the Cross River and to the waiting ships of the Europeans. This process in which all laws and customs were distorted and broken to capture slaves and more slaves had devastating effects on political centralization, though in some places it did lead to the rise of powerful states whose main raison d’être was raiding and slaving. The Kingdom of Kongo itself was probably the first African state to experience a metamorphosis into a slaving state, until it was destroyed by civil war. Other slaving states arose most prominently in West Africa and included Oyo in Nigeria, Dahomey in Benin, and subsequently Asante in Ghana.

The expansion of the state of Oyo in the middle of the seventeenth century, for example, is directly related to the increase of slave exports on the coast. The state’s power was the result of a military revolution that involved the import of horses from the north and the formation of a powerful cavalry that could decimate opposing armies. As Oyo expanded south toward the coast, it crushed the intervening polities and sold many of their inhabitants for slaves. In the period between 1690 and 1740, Oyo established its monopoly in the interior of what came to be known as the Slave Coast. It is estimated that 80 to 90 percent of the slaves sold on the coast were the result of these conquests. A similar dramatic connection between warfare and slave supply came farther west in the eighteenth century, on the Gold Coast, the area that is now Ghana. After 1700 the state of Asante expanded from the interior, in much the same way as Oyo had previously. During the first half of the eighteenth century, this expansion triggered the so-called Akan Wars, as Asante defeated one independent
state after another. The last, Gyaman, was conquered in 1747. The preponderance of the 375,000 slaves exported from the Gold Coast between 1700 and 1750 were captives taken in these wars.

Probably the most obvious impact of this massive extraction of human beings was demographic. It is difficult to know with any certitude what the population of Africa was before the modern period, but scholars have made various plausible estimates of the impact of the slave trade on the population. The historian Patrick Manning estimates that the population of those areas of West and West-Central Africa that provided slaves for export was around twenty-two to twenty-five million in the early eighteenth century. On the conservative assumption that during the eighteenth and early nineteenth centuries these areas would have experienced a rate of population growth of about half a percent a year without the slave trade, Manning estimated that the population of this region in 1850 ought to have been at least forty-six to fifty-three million. In fact, it was about one-half of this.

This massive difference was not only due to about eight million people being exported as slaves from this region between 1700 and 1850, but the millions likely killed by continual internal warfare aimed at capturing slaves. Slavery and the slave trade in Africa further disrupted family and marriage structures and may also have reduced fertility.

Beginning in the late eighteenth century, a strong movement to abolish the slave trade began to gain momentum in Britain, led by the charismatic figure of William Wilberforce. After repeated failures, in 1807 the abolitionists persuaded the British Parliament to pass a bill making the slave trade illegal. The United States followed with a similar measure the next year. The British government went further, though: it actively sought to implement this measure by stationing naval squadrons in the Atlantic to try to stamp out the slave trade. Though it took some time for these measures to be truly effective, and it was not until 1834 that slavery itself was abolished in the British Empire, the days of the Atlantic slave trade, by far the largest part of the trade, were numbered.

Though the end of the slave trade after 1807 did reduce the external
demand for slaves from Africa, this did not mean that slavery’s impact on African societies and institutions would magically melt away. Many African states had become organized around slaving, and the British putting an end to the trade did not change this reality. Moreover, slavery had become much more prevalent within Africa itself. These factors would ultimately shape the path of development in Africa not only before but also after 1807.

In the place of slavery came “legitimate commerce,” a phrase coined for the export from Africa of new commodities not tied to the slave trade. These goods included palm oil and kernels, peanuts, ivory, rubber, and gum arabic. As European and North American incomes expanded with the spread of the Industrial Revolution, demand for many of these tropical products rose sharply. Just as African societies took aggressive advantage of the economic opportunities presented by the slave trade, they did the same with legitimate commerce. But they did so in a peculiar context, one in which slavery was a way of life but the external demand for slaves had suddenly dried up. What were all these slaves to do now that they could not be sold to Europeans? The answer was simple: they could be profitably put to work, under coercion, in Africa, producing the new items of legitimate commerce.

One of the best documented examples was in Asante, in modern Ghana. Prior to 1807, the Asante Empire had been heavily involved in the capturing and export of slaves, bringing them down to the coast to be sold at the great slaving castles of Cape Coast and Elmina. After 1807, with this option closed off, the Asante political elite reorganized their economy. However, slaving and slavery did not end. Rather, slaves were settled on large plantations, initially around the capital city of Kumase, but later spread throughout the empire (corresponding to most of the interior of Ghana). They were employed in the production of gold and kola nuts for export, but also grew large quantities of food and were intensively used as porters, since Asante did not use wheeled transportation. Farther east, similar adaptations took place. In Dahomey, for example, the king had large palm oil plantations near the coastal ports of Whydah and Porto Novo, all based on slave labor.

So the abolition of the slave trade, rather than making slavery in Africa wither away, simply led to a redeployment of the slaves, who were now used within Africa rather than in the Americas. Moreover, many of the political institutions the slave trade had wrought in the previous two centuries were unaltered and patterns of behavior persisted. For example, in Nigeria in the 1820s and ’30s the once-great Oyo Kingdom collapsed. It was undermined by civil wars and the rise of the Yoruba city-states, such as Illorin and Ibadan, that were directly involved in the slave trade, to its south. In the 1830s, the capital of Oyo was sacked, and after that the Yoruba cities contested power with Dahomey for regional dominance. They fought an almost continuous series of wars in the first half of the century, which generated a massive supply of slaves. Along with this went the normal rounds of kidnapping and condemnation by oracles and smaller-scale raiding. Kidnapping was such a problem in some parts of Nigeria that parents would not let their children play outside for fear they would be taken and sold into slavery.

As a result slavery, rather than contracting, appears to have expanded in Africa throughout the nineteenth century. Though accurate figures are hard to come by, a number of existing accounts written by travelers and merchants during this time suggest that in the West African kingdoms of Asante and Dahomey and in the Yoruba city-states well over half of the population were slaves. More accurate data exist from early French colonial records for the western Sudan, a large swath of western Africa, stretching from Senegal, via Mali and Burkina Faso, to Niger and Chad. In this region 30 percent of the population was enslaved in 1900.

Just as with the emergence of legitimate commerce, the advent of formal colonization after the Scramble for Africa failed to destroy slavery in Africa. Though much of European penetration into Africa was justified on the grounds that slavery had to be combated and abolished, the reality was different. In most parts of colonial Africa, slavery continued well into the twentieth century. In Sierra Leone, for example, it was only in 1928 that slavery was finally abolished, even though the capital city of Freetown was originally established in the late eighteenth century as a haven for slaves repatriated from the
Americas. It then became an important base for the British antislavery squadron and a new home for freed slaves rescued from slave ships captured by the British navy. Even with this symbolism slavery lingered in Sierra Leone for 130 years. Liberia, just south of Sierra Leone, was likewise founded for freed American slaves in the 1840s. Yet there, too, slavery lingered into the twentieth century; as late as the 1960s, it was estimated that one-quarter of the labor force were coerced, living and working in conditions close to slavery. Given the extractive economic and political institutions based on the slave trade, industrialization did not spread to sub-Saharan Africa, which stagnated or even experienced economic retardation as other parts of the world were transforming their economies.

The “dual economy” paradigm, originally proposed in 1955 by Sir Arthur Lewis, still shapes the way that most social scientists think about the economic problems of less-developed countries. According to Lewis, many less-developed or underdeveloped economies have a dual structure and are divided into a modern sector and a traditional sector. The modern sector, which corresponds to the more developed part of the economy, is associated with urban life, modern industry, and the use of advanced technologies. The traditional sector is associated with rural life, agriculture, and “backward” institutions and technologies. Backward agricultural institutions include the communal ownership of land, which implies the absence of private property rights on land. Labor was used so inefficiently in the traditional sector, according to Lewis, that it could be reallocated to the modern sector without reducing the amount the rural sector could produce. For generations of development economists building on Lewis’s insights, the “problem of development” has come to mean moving people and resources out of the traditional sector, agriculture and the countryside, and into the modern sector, industry and cities. In 1979 Lewis received the Nobel Prize for his work on economic development.
