Some stories survive because history has preserved enough evidence to tell us exactly what happened. Others endure because the evidence stops at the edge of the story, leaving behind questions that generations continue to ask. The story of the Malian emperor who sailed west into the Atlantic belongs to the latter. It is a story of wealth, sovereignty, curiosity and disappearance, beginning in one of the most powerful empires of medieval West Africa and ending somewhere beyond the horizon, where a ruler and his fleet vanished from the historical record.
We come to know of this story through Mansa Musa, the celebrated ruler of the Mali Empire whose pilgrimage to Mecca in 1324 carried the fame of his kingdom across the Islamic world. During his journey, Musa spent about three months in Cairo, where he spoke with people who were fascinated by the wealth and power of the empire he ruled. Among them was an Egyptian Emir, whose conversations with Musa eventually reached the historian al-Umari, who recorded what he had learned about Mali and its ruler.
Among the things Musa reportedly explained was how he had come to occupy the throne — a rather interesting story that must be shared. Apparently, Musa’s predecessor had become determined to discover the limits of the Atlantic Ocean. He wanted to know whether the great western sea eventually came to an end or whether something existed beyond the visible horizon.
He first sent an expedition to find out. According to Musa's account, the fleet consisted of 200 ships carrying men and another 200 ships carrying provisions. The ships sailed westward into the Atlantic and remained away for a long time. Eventually, only one vessel returned. Its captain explained that the fleet had encountered a powerful current in the middle of the ocean, something that appeared almost like a river flowing through the sea. The other ships had entered the current and disappeared, while his own vessel had remained behind and eventually turned back.
The emperor was not satisfied. As Musa told it, his predecessor could not accept that the ocean simply ended — the river Niger had another bank, so why not the sea? Rather than abandoning the expedition, he prepared another one on a much greater scale. This time, according to the account, 2,000 ships were assembled. One thousand were prepared for the emperor himself, and the men who would accompany him, while another thousand carried water and provisions. Musa was appointed to govern Mali in his predecessor's absence, and the emperor himself sailed west with the fleet but never returned. That disappearance became one of the enduring mysteries associated with medieval Africa.
The Emperor Without A Name
The identity of the ruler who supposedly led the expedition remains uncertain. You may have heard this ruler called “Abubakari II” or “Abu Bakr II.” The first thing to know is that the name is almost certainly wrong. Al-Umari’s account gives no name at all — only “Musa’s predecessor.” The name “Abu Bakr II” entered the story through a nineteenth-century error, when the European scholar Baron de Slane mistranslated the great historian Ibn Khaldun and inserted into the line of Malian kings an “Abu Bakr” who was never actually a ruler — he was an ancestor of Musa’s lineage, a relative of the empire’s founder, Sundiata. By Ibn Khaldun’s own account, Musa’s real predecessor was a Mansa Muhammad. The seafaring emperor, if he existed, was most likely Muhammad, not the “Abubakari II” of popular retelling.
Later historians have attempted to reconstruct Mali's royal succession, and some have connected the expedition with Muhammad ibn Qu, whom Ibn Khaldun identified as Musa's predecessor. The name Abu Bakr II therefore belongs to a later historical interpretation rather than an identification that can be established directly from the original account.
The uncertainty surrounding his name is fitting in a strange way. His identity is debated, his destination is unknown and his fate has never been established. What remains is the account Musa gave: a predecessor fascinated by the Atlantic, a first expedition that disappeared, a second expedition on an even greater scale and a ruler who sailed with it and never returned.
The Ruler who Became Famous
The disappearance of Musa's predecessor brought Mansa Musa to the throne, and this man, who inherited the empire, would become one of the most famous rulers of medieval Africa.
His pilgrimage to Mecca in 1324 would transcend his reputation beyond West Africa. In that year, Musa travelled with a large entourage and vast quantities of gold, and his generosity in Cairo attracted considerable attention. Stories of his wealth soon spread throughout North Africa and the Islamic world. His reputation eventually reached European cartographers as well. The famous Catalan Atlas of 1375 depicts a West African ruler holding gold, widely understood to represent Mansa Musa, showing us how Mali's wealth had entered the geographical imagination of people far beyond the empire itself.
The contrast between Musa and his predecessor is striking. Musa travelled far and returned, leaving behind witnesses who could describe his wealth and presence while his predecessor travelled west and disappeared, leaving behind only the story of a journey whose destination remains unknown. One became famous because the world saw him. The other became memorable because the world never saw him again.
What Happened to the Expedition?
The possibility that the Malian expedition reached the Americas has fascinated historians and the wider public for generations. The idea rests partly on the fact that Atlantic currents can carry vessels across enormous distances and partly on the scale of the expedition described by Musa. Yet, possibility is not proof. There is no universally accepted archaeological evidence demonstrating that the Malian fleet reached the Americas. There is no surviving Malian document describing an arrival on another continent, and no independent contemporary source confirms that the expedition established contact with the Americas.
Various theories have pointed to supposed similarities between West African and American cultures, plants and technologies. However, these claims have not produced sufficient evidence to establish pre-Columbian Malian contact with the Americas. The historical position therefore remains one of uncertainty.
The possibilities are many. Storms may have destroyed the fleet. Powerful currents may have carried the ships far from their intended route. The expedition may have exhausted its food and water. Ships may have been damaged or separated from one another. Some vessels may even have reached distant shores without establishing a lasting presence that later historians could identify. There is also the possibility that the story changed as it travelled through time.
The Atlantic would later become one of the most important spaces in world history, carrying explorers, merchants, conquerors and millions of enslaved Africans across its waters. Long after the Malian expedition disappeared into history, the same ocean would become central to the transatlantic slave trade and the forced movement of African people to the Americas.
The earlier story therefore belongs to a very different chapter of Atlantic history. Here, the movement was reportedly driven by curiosity and exploration rather than captivity. The attempt itself is significant because it reminds us that the desire to explore was not born in Europe, nor did the world's oceans become objects of human curiosity only when European ships began crossing them. Long before the voyages that would later reshape the Atlantic world took place, a ruler from Mali was already looking west.

So did it happen at all? Here caution is required. Al-Umari’s is the only record — no other Arab chronicler and no West African oral tradition mentions the voyage, and that silence is a genuine reason for doubt. And yet serious historians, among them John Thornton and Nehemia Levtzion, have treated the account as plausible rather than fanciful. One detail in particular gives it weight: the “river in the ocean” that swallowed the first fleet closely matches the Canary Current, a real and powerful Atlantic feature that would indeed sweep ships away from the West African coast. Whoever told that story knew something true about the sea.
The most fitting ending to the story is that so much about the emperor remains uncertain. His commonly used name, Abu Bakr II, is disputed, his precise identity remains debated, his route is unknown, his destination is unknown and his fate is unknown. Perhaps “The Unknown,” would be a more fitting title for this article.
Even the exact scale of the expedition cannot be independently verified with certainty. Yet the story survives because Mansa Musa remembered it and al-Umari recorded it. Mansa Musa inherited the throne and carried the fame of Mali into the wider world, while the ruler who preceded him became a shadow at the edge of history.
What remains is a story about an African empire that possessed the wealth, organisation and imagination to look beyond itself. Mali had already crossed the Sahara, connected distant markets and participated in the intellectual life of the Islamic world. Its merchants knew the value of distant trade, its scholars knew the value of distant knowledge, and one of its rulers appears to have believed that the Atlantic deserved to be explored. Centuries later, the horizon still holds the question he sailed to answer.
