Biography
Mansa Musa I was Emperor of the Mali Empire from 1312 to 1337 and is frequently cited as the wealthiest person in recorded history. His empire stretched across modern-day Mali, Senegal, Gambia, Guinea, Niger, Nigeria, Chad, and Mauritania — sitting atop perhaps 50% of the world's known gold supply at the time, along with vast salt deposits. Estimates of his net worth, adjusted to modern terms, range from $300 billion to $400 billion, though these comparisons involve significant uncertainty.
What is historically documented is the impact of his 1324 hajj to Mecca: he traveled with roughly 60,000 people, 12,000 of whom were slaves carrying four pounds of gold each. He gave gold away so freely along his route through Cairo that he caused hyper-inflation in Egypt — the gold market crashed and took over a decade to recover. Contemporary Egyptian historians documented this event extensively.
Mansa Musa transformed his capital, Timbuktu, from a trading post into one of the world's great centers of learning. He funded the Sankore Mosque and the University of Timbuktu, which at its peak had over 25,000 students. His legacy is the intersection of extraordinary wealth and extraordinary cultural investment.

When Mansa Musa passed through Cairo on his 1324 hajj, he gave away so much gold that Egypt's gold market crashed — and it took over 12 years to recover. He is the only person in history documented to have single-handedly caused a decade-long economic depression by being too generous.
