Who is Mansa Musa?

Mansa Musa, the ninth Mansa of the Mali Empire, who ruled from roughly 1312 to 1337, is widely regarded as the wealthiest person in recorded history, a Mandinka ruler who inherited the gold fields that once powered the Ghana Empire we have been tracing and turned them into the most spectacular display of wealth the medieval world had ever seen. He came to the throne after the king before him, Muhammad ibn Qu (often called Abu Bakr II), sailed into the Atlantic with 2,000 ships and was never seen again.

Their story

Mansa Musa was a member of the powerful Keita clan, whose members ruled the West African empire of Mali from around 1250. According to the Muslim Arab historian Ibn Khaldun, Musa was the ninth ruler of Mali and a grandnephew of its founder, Sundiata Keita. He was not the direct heir to the throne. Mansa Musa gained the throne after his predecessor, Mansa Abu Bakr II, sailed out into the Atlantic with a large fleet of ships and was never seen again.

The connection to this conversation is direct: the gold fields that made the Ghana Empire (Wagadu) legendary were now inside Mali's territory. Sundiata Keita moved to expand the kingdom of Mali by taking control of all the Soninke peoples recently conquered by the Sosso, and their territory comprised much of the former kingdom of Ghana and its nominally independent vassal states. Musa inherited that foundation and built something larger still.

In His Own Words

Mansa Musa left no writings of his own. His words come down to us through al-Umari, a scholar who gathered accounts in Cairo from people who spent time with Musa during his visit. Chief among them was the official Ibn Amir Hajib, who looked after him in Cairo.

“We belong to a house which hands on the kingship by inheritance.” (to Ibn Amir Hajib, Cairo, 1324)

“The king who was my predecessor did not believe that it was impossible to discover the furthest limit of the Atlantic Ocean.” (on the voyage that made him king)

“So he equipped 200 ships filled with men and the same number equipped with gold, water, and provisions.” (on the first fleet)

“Then that sultan got ready 2,000 ships, 1,000 for himself and the men whom he took with him and 1,000 for water and provisions.” (on the second fleet)

“That was the last we saw of him and all those who were with him, and so I became king in my own right.” (on how he came to the throne)

“I came for the Pilgrimage and nothing else. I do not wish to mix anything else with my Pilgrimage.” (when invited to meet the Sultan of Egypt)

“How may this be?” (when told he must kiss the ground before the Sultan)

“I make obeisance to God who created me!” (as he bowed, making clear he bowed to God alone)

“Not even to kings?” (when Ibn Amir Hajib told him Islamic law forbade a custom of his court, which he then gave up)

Did He Disappear at Sea?

No. It was the king before him who sailed west and never came back. In Musa's own account, his predecessor sent 200 ships into the Atlantic, then set out himself with 2,000, leaving Musa to rule as his deputy. When the fleet never returned, Musa became king.

Musa went on to rule for about 25 years. He made his pilgrimage to Mecca in 1324 and 1325, came home and ruled until he died around 1337.

Many popular accounts name that sailing king Abu Bakr II. Historians point out this name comes from a 19th-century mistranslation of Ibn Khaldun. Ibn Khaldun names Musa's predecessor as Muhammad ibn Qu, and several historians credit the voyage to him. Some historians also question the story itself, suggesting it may have explained how Musa, who was not next in line, came to power.

Did He Show Off His Wealth to Prove His Right to Rule?

The sources never say so in his words. He told his hosts in Cairo that he came for the pilgrimage “and nothing else.” But the journey did a great deal for him and for Mali. It made him famous across North Africa, the Middle East and Europe. It built ties with the sultans of Egypt and Morocco. And it brought scholars and the architect Abu Ishaq al-Sahili back to Mali, where they helped make Timbuktu a center of learning.

Was it also about his standing at home? Musa was not the direct heir, and he came to power through his predecessor's disappearance. Whether the display was also meant to secure his place at home is a question the record does not settle.

His Family

Mansa Musa was Mandinka, a member of the Keita dynasty founded by Sundiata Keita, the founder of the Mali Empire.

  • Wife: his senior wife was Inari Kunate. She traveled with him on the pilgrimage, with her own attendants.
  • Children: his son Maghan, also written Magha, succeeded him as king around 1337. While Musa was on pilgrimage, he left a son named Muhammad to rule in his place.

What the Numbers Really Say

Later writers made his caravan bigger with every telling. Sources from his own time describe thousands of his soldiers and companions, mostly free West African Muslims. The famous 60,000 comes from a chronicle written in 1655, more than 300 years later, and historians call it greatly inflated.

What he built

Mansa Musa was the ruler of the Mali Empire in West Africa from 1312 to 1337. Controlling territories rich in gold and copper, and monopolizing trade between the north and interior of the continent, Mali grew extremely wealthy. With an army numbering around 100,000 men, including an armored cavalry corps of 10,000 horses, and with the talented general Saran Mandian, Mansa Musa was able to extend and maintain Mali's vast empire, doubling its territory and making it second in size only to that of the Mongol Empire at the time.

When he died, the empire included what is now Senegal, southern Mauritania, northern Ghana, Mali, northern Burkina Faso, Guinea, Guinea-Bissau, The Gambia, and Ivory Coast.

The pilgrimage that crashed the gold market

Mansa Musa, like many other devout Mali rulers before and after, set off for a pilgrimage to Mecca, but when he arrived in Cairo en route, he caused an absolute sensation. He was accompanied by 60,000 men, including soldiers, entertainers, his entire royal court, and 12,000 enslaved people, as well as herds of goats and sheep and about a hundred camels carrying some 300 pounds of gold each.

What happened next is one of the most remarkable economic events in recorded history. In Egypt, Mansa Musa and his people gave away or spent so much that they caused the price of gold to plummet, and it would take 12 years for the Egyptian economy to recover. His pilgrimage also led to more than $1 billion in economic losses across the Middle East overall, as his caravan caused the depreciation of gold wherever it went.

Realizing what he had done, on his way back from Mecca, he borrowed all of the gold he could carry from moneylenders in Cairo at high interest, trying to drain back some of the gold he had flooded into the market. It is the only time in recorded history one man directly controlled the price of a global commodity in both directions within a single journey.

His wealth in numbers

The empire controlled the gold mines of Bambuk, Boure, and Galam, which produced more than half of the Old World's gold during Mansa Musa's reign. Modern estimates place his net worth in ranges that strain historical imagination, often expressed in inflation-adjusted terms as hundreds of billions of dollars. The most commonly cited figure is around $400 billion in today's money, though some historians argue the fortune was so structural, tied to Mali's monopoly over both gold and salt, that it simply cannot be calculated by any modern metric.

Timbuktu: the greater legacy

The gold was spectacular. But what Musa did with the scholars he brought back from Mecca may have mattered more. He brought back architects and scholars from his pilgrimage who would build mosques and universities that made cities like Timbuktu internationally famous. Timbuktu became known for its mosques, libraries and centers of learning. Students studied Islamic law, theology, astronomy, mathematics, medicine and literature, while scholars produced and preserved manuscripts covering a wide range of subjects. The city became part of a wider intellectual network stretching across West Africa, North Africa and the Middle East.

He extended the empire to include Gao, commissioned mosques and palaces through the Granada architect Abu Ishaq al-Sahili, and encouraged the scholars of Timbuktu and Sankore. His wealth and generosity were described by the Arabic writers al-Umari, Ibn Battuta and Ibn Khaldun, and his image, enthroned with a gold nugget, was drawn on the Catalan Atlas of 1375.

The Catalan Atlas of 1375, drawn in Majorca half a century after Musa's journey, depicts him seated and crowned, holding a golden orb, identified by name. He is among the first sub-Saharan African rulers to appear on a European world map in this manner. European mapmakers concluded that their picture of the world was simply incomplete without him.

After his death

After his death around 1337, the stability of the Mali Empire was undermined, leading to its eventual decline as the Songhai Empire emerged. But the intellectual tradition he built in Timbuktu outlasted the political empire by centuries. Well after his death, Mansa Musa remained engraved in the imagination of the world as a symbol of fabulous wealth. However, his riches are only one part of his legacy, and he is also remembered for his Islamic faith, promotion of scholarship, and patronage of culture in Mali.

Where did the Greek learn from? Where did the Romans learn from?

The ancient Greeks were voracious borrowers. Their debt to Africa was enormous and openly acknowledged by the Greeks themselves. Thales of Miletus, credited as the first Greek philosopher, studied geometry in Egypt. Pythagoras spent years there. Plato visited.
