In the summer of 1324, a procession of some sixty thousand people, including twelve thousand servants in Persian silk, moved slowly into Cairo from the western desert. At its head rode Mansa Musa, the ninth emperor of Mali, on his way to Mecca, a man the Egyptians had been told to expect for months. According to the chroniclers, he brought with him a hundred camels, each loaded with roughly three hundred pounds of gold. He gave the gold away to courtiers, merchants, beggars, and to the sultan of Egypt, whose hospitality he accepted only on the condition that he not be made to kneel. When he left, three months later, the price of gold in Cairo had collapsed. It would, by some accounts, take a decade for the market to recover. The Arab historian al-‘Umari, writing afterward, recorded the figure with something between awe and irritation. A single African king, he noted, had walked into the richest city in the Mediterranean world and broken its currency by being generous.
This is the story everyone now tells about Mansa Musa. It is the story by which the Mali Empire, a state that controlled an area larger than Western Europe and lasted for four hundred years, is mostly remembered. An online cottage industry has grown up around the claim that Musa was the wealthiest individual in human history. His fortune was estimated at four hundred billion dollars. This figure is invented, since the medieval economy was not denominated in dollars, and gold was not the only or even the principal form of West African wealth. The comparison flattens eight hundred years of monetary change. It captures, by accident, the disorientation that Musa’s caravan produced in the fourteenth-century Islamic world, and the disorientation that the Mali Empire still produces in a popular history that, until quite recently, did not quite believe it had existed.
Mali’s emergence had less to do with gold than with the collapse of an older order. By the late twelfth century, the Ghana Empire, the great Sahelian state that for more than three hundred years had taxed the caravans crossing between the gold fields of the upper Niger and the salt mines of the Sahara, was failing. Into the gap stepped the Sosso, a kingdom under a warlord named Sumanguru Kanté, who in the standard telling of the story conquered the Mandinka people of the upper Niger and killed eleven of the twelve royal sons of Niani. The twelfth, Sundiata Keita, was spared, the legend goes, because he could not walk. He was weak and considered an embarrassment to his family. He was also, eventually, the founder of Mali.
The Epic of Sundiata, the oral history that the griots of West Africa have transmitted for nearly eight centuries, gives this story the shape of myth. It is the story of a lame prince who learns to walk by sheer will, fashions iron leg braces at the age of seven, flees into exile, returns at the head of an army of allied chiefdoms, and defeats Sumanguru at the Battle of Kirina in 1235 by wounding him with an arrow tipped with a cock’s spur. The Mande oral tradition is not history in the European chronicle sense. There are several versions of Sundiata, and they do not always tell the same story. Its core, however, is supported by the Arab travelers who arrived in the next century, including Ibn Battuta and Ibn Khaldun, both of whom treated him as a historical king. After Kirina, Sundiata's realm took the form of a federation rather than a centralized kingdom. The Kouroukan Fouga, the constitutional charter he is credited with promulgating, divided his realm into provinces governed by trusted lieutenants, granted hereditary rights to founding clans, and codified obligations between rulers and ruled in a manner some scholars have compared, perhaps optimistically, to a medieval bill of rights. The capital he established at Niani sat at the hinge of the gold and salt trades.
The gold itself came from the Bambuk and Bure fields, in the forested country south and west of the Niger, and later from the Akan deposits farther southeast. The Malian state did not, as a rule, dig the gold. The mining was done by communities that remained outside the empire’s direct control by long-standing arrangement. What Mali did was tax the caravans and guarantee the security of the routes. Traders were willing to pay handsomely for the services because the alternative was banditry. At its peak, in the early fourteenth century, some estimates suggest West Africa supplied something close to two-thirds of the gold circulating in the medieval Mediterranean. The dinars of Cairo, the florins of Florence, and eventually the gold coins of England were, to a degree historians are still debating, minted from metal that had passed through Malian hands.
Sundiata’s successors expanded the system. By the reign of his grandnephew, Mansa Musa, who came to the throne around 1312, the empire stretched from the Atlantic coast of present-day Senegal to the eastern edges of modern Niger, encompassing in whole or in part the territory of nine modern nations. By some estimates, its army was numbered at a hundred thousand men, including ten thousand cavalry. Its principal cities, including Niani, Timbuktu, Gao, Djenné, and Walata, functioned as nodes in a commercial network that ran from the Mediterranean to the rainforest. By the time Musa decided to make his pilgrimage, Mali was one of the four or five most powerful states on earth.
Beyond the famous monetary catastrophe in Cairo, the pilgrimage also put Mali on the map. In 1375, four decades after Musa’s death, the cartographer Abraham Cresques produced a magnificent atlas for the king of Aragon. In the lower portion of his rendering of Africa, he drew a Black king seated on a throne, holding a gold nugget, with a Tuareg merchant approaching on a camel. The legend identified him as “Musse Melly,” the richest and most noble king of the region. It was one of the earliest known depictions of a sub-Saharan African ruler on a European map. The cartographic afterlife of Musa’s hajj placed West Africa inside the mental geography of late-medieval Europe. It also planted the idea that the source of the world’s gold lay somewhere south of the Sahara. The Portuguese caravels that began coasting down the Atlantic seaboard in the fifteenth century were, in part, sailing toward a map made by a Jewish cartographer in Majorca after the death of a Malian king.
Musa returned home in 1325, by way of Gao, where he accepted the submission of the Songhai king. He commissioned the great mosques of Timbuktu and Gao, including the Djinguereber, which is still standing, built of mud brick in a style traditionally credited to an Andalusian architect he had recruited along the route. He encouraged Muslim scholars to settle in Timbuktu, whose Sankore complex would, by the sixteenth century, function as one of the great universities of the Islamic world. By the time Musa died, sometime between 1332 and 1337, the empire had reached its peak.
The collapse of the empire happened gradually. Musa’s son Maghan, who inherited the throne, is often portrayed as a weak ruler, although how much of this reflects genuine assessment and how much retrospective explanation for what followed is difficult to say. The Mossi people to the south began raiding Malian territory, and Timbuktu was sacked and burned. Maghan was succeeded by his uncle, Mansa Sulayman, Musa’s brother, who held the empire together for nearly two decades. It was during Sulayman’s reign that Ibn Battuta, the Moroccan jurist who by then had spent thirty years travelling from Tangier to Beijing, finally arrived in Mali. He spent eight months there and came away impressed by the security travelers enjoyed and the seriousness with which Islamic learning was pursued. He found Sulayman, however, to be a miser, and recorded with offense that the king’s hospitality gift to him had consisted of bread, a piece of fried beef, and sour milk.
The miserliness has a context Ibn Battuta did not understand. The Black Death, which entered Egypt in 1347 and tore through the Mediterranean for the next five years, reached the Sahel along the same caravan routes that had carried Mali’s gold north. A 2017 study from William and Mary, drawing on settlement-pattern evidence, has suggested that the plague killed between thirty and fifty per cent of the population of the Western Sudan (the medieval West African Sahel, not modern Sudan). Sulayman, in this reading, was not stingy, since he was running an empire whose tax base had been cut in half. He was the last great mansa of Mali. When he died, around 1359, the succession dissolved into civil war and his son Qasa reigned for nine months. Musa’s grandson, Mari Djata II, took the throne by force and is remembered, by Ibn Khaldun, as a tyrant who sold a twenty-qintar boulder of imperial gold to North African merchants for far less than it was worth.
A slow erosion followed across two centuries. The Tuareg seized Timbuktu in 1433, the Mossi continued their raids, and the Songhai, who had been a Malian dependency, broke away under their Sonni dynasty in the 1430s. In 1468, the Songhai king Sunni Ali captured Timbuktu, and in 1473 he took Djenné after a siege the chronicles record as lasting seven years, seven months, and seven days, the city surrendering out of hunger. By the end of the fifteenth century, the Mali Empire had been reduced to a rump statelet around its old Mande heartland. Meanwhile, the Portuguese had begun arriving by sea on the Atlantic coast, and the trans-Saharan trade began to lose its monopoly on West African gold. Mahmud Keita IV, the last mansa whose authority extended beyond a few districts, died around 1610, leaving three sons who fought over what was left. No single ruler from the Keita dynasty ruled again, and according to oral tradition, the empire ended in a family quarrel.
Although it is tempting to read Mali's story as a parable about the fragility of powerful states, that reading misses much of what made the empire remarkable. The empire endured for longer than the United States has currently existed, and its scholarly tradition outlived its political one by another two centuries. The manuscripts of Timbuktu, hidden in family libraries through the upheavals that followed, are still being catalogued today. Its languages, clan structures, traditions, and the iconography of the lion and the bow survive across a dozen modern West African countries.
All empires fall. The more interesting question is why Mali remains so faint in global memory. How did a state that dominated the gold trade, fostered one of the great centres of learning in the medieval Islamic world, and made Mansa Musa famous from Cairo to the Mediterranean become little more than a footnote in many accounts of world history?
