From a site called Celebrity Net Worth (I know, blech), a list of the 25 richest people of all time, adjusted for inflation. Gates, Buffett, and Rockefeller all make the list but the big cheese is Malian emperor Mansa Musa I, with a net worth of $400 billion in today’s dollars.
Mansa Musa I of Mali is the richest human being in history with a personal net worth of $400 billion! Mansa Musa lived from 1280 - 1337 and ruled the Malian Empire which covered modern day Ghana, Timbuktu and Mali in West Africa. Mansa Musa’s shocking wealth came from his country’s vast production of more than half the world’s supply of salt and gold.
