History of Wealth - Richest People of All Time
From Mansa Musa to Elon Musk - a journey through the richest people in history, their fortunes adjusted for inflation, and how they built their wealth.
Wealth is nothing new. For as long as civilization has existed, certain individuals have amassed fortunes so immense that they became legend. From African emperors who crashed gold markets to industrialists who built America, here is the definitive timeline of the richest people in history - with net worths adjusted to today's dollars.

The Song Dynasty emperor controlled roughly 30% of global GDP at its peak - the largest economy in the world at the time, powered by innovation in agriculture, trade, and taxation.
John Jacob Astor

Note on methodology: Comparing wealth across centuries is inherently imprecise. Different sources use different methods - inflation-adjusted dollars, GDP share, or purchasing power parity. Figures shown represent ranges from reputable estimates (Forbes, Bloomberg, Business Insider, academic research). Mansa Musa's wealth is particularly difficult to quantify; most historians agree he was the wealthiest person in history by any measure.
