The Top 10 Richest People of All Time

When people think of extreme wealth, modern billionaires like Elon Musk or Jeff Bezos often come to mind. However, history tells a much bigger story. Some individuals in the past controlled entire empires, resources, and economies so vast that their wealth far surpasses anything seen today.

Because money, currencies, and economies have changed over centuries, historians measure historical wealth not just in cash, but in economic power, land ownership, and control over resources. Using these factors, here are the top 10 richest people of all time.

1. Mansa Musa – The Richest Person in History

Mansa Musa, ruler of the Mali Empire in the 14th century, is widely regarded as the wealthiest human being who ever lived. His empire controlled enormous amounts of gold and salt, two of the most valuable resources of the medieval world.

During his famous pilgrimage to Mecca, Mansa Musa distributed so much gold that he caused inflation in parts of North Africa and the Middle East that lasted for years. His wealth was so vast that historians describe it as impossible to calculate.

Augustus Caesar, the first Roman Emperor, ruled an empire that controlled nearly one-third of the world’s economy at the time. His wealth came not just from personal possessions, but from total control over Roman taxes, land, and military resources.

Adjusted for modern values, Augustus is often estimated to have controlled wealth worth over $4 trillion.
