Top 10: Richest People (of All-Time)

If you’re like most people, you’ve fantasized about what it would be like to be super rich. Maybe you have even pondered how to finagle your way into marrying the richest man in the world (Mexican business magnate Carlos Slim, net worth: $69 billion) or the world’s richest woman (Australian mining tycoon Gina Rinehart, estimated net worth: $29 billion). Nevertheless, not the assets of Slim and Rinehart combined, nor even the peak wealth of other modern mega-billionaires like Warren Buffet and Bill Gates, can compare to the riches of the top 10 richest people of all -time, compiled here in this list. Keep in mind that the estimated peak wealth amounts listed here are inflation-adjusted for today’s (U.S.) dollars. Oh, and there’s no hope of marrying or winning a lucrative lawsuit against any of these powerful men – they’re all dead.

About: You didn’t think our Norman friend William the Conqueror, a.k.a. William I, a.k.a. William the Bastard, gave all of the spoils of war from invading England in 1066 to his cousin Alan Rufus, did you? Of course not! After conquering Britain, William (who, in case you were wondering, got his“Bastard” nickname from being the illegitimate son of the Duke of Normandy) set about to confiscate the estates of English nobles and their heirs. By the end of his reign, a small group of the King’s inner circle had acquired about half of England’s landed wealth. A shrewd conqueror if there ever was one, William also enacted various campaigns to maximize tax revenues from his subjects.

Carnegie’s is a “rags to riches” story: after emigrating from Scotland to the U.S. in 1848, Carnegie’s first job was as a factory worker. He was promoted to bill logger, then to messenger boy, and later rose through the ranks at a telegraph company. Eventually, Andrew Carnegie built his own exceedingly successful steel company. Carnegie acquired the majority of his wealth after selling his Carnegie Steel Company to J.P. Morgan for an astounding $480 million in 1901. From this company, Morgan created U.S. Steel, which is still one of the major steel companies in existence today. Carnegie’s name also continues to live on, with many universities, libraries, foundations, and landmarks bearing his name, including the world-famous Carnegie Hall concert venue in New York City.

2. John D. Rockefeller


Lived: 1839 to 1937

Estimated Peak Wealth: $336 to $340 billion

About: Like Cornelius Vanderbilt and Andrew Carnegie, John D. Rockefeller, the man for whom Manhattan’s famous Rockefeller Center was named, was another legendary American industrialist and philanthropist. Rockefeller’s main business was oil; his Standard Oil Company, formed in 1870, dominated the petroleum industry at a time when gasoline and kerosene began to soar in importance. As a result, Rockefeller became the world’s richest man. Rockefeller also became the first American billionaire – in 1916 dollars! While often criticized for his monopolistic business methods, with his vast wealth, Rockefeller was able to create charitable foundations which had major impacts in the fields of education, scientific research, and medicine. Notably, medical research funded by Rockefeller’s foundations helped to eradicate diseases such as yellow fever and hookworm.

1. Mansa Musa


Estimated Peak Wealth: $400 billion

Lived: 1280 to 1337

About: Although there is a good chance that you have never heard of him, Mansa Musa, also sometimes referred to as Musa I of Mali, was an African king who by some modern estimates, was the richest human being in history. Musa was the Emperor of the Malian Empire, which, at the time, spanned approximately 500,000 square miles in western Africa. Historians say Musa’s wealth came from his empire’s production of more than half the world’s gold and salt. A devout Muslim, when making his Hajj, or pilgrimage to Mecca, in 1324, Musa’s procession is said to have included 72,000 men, including 12,000 slaves, and 80 camels, carrying thousands of pounds of gold dust. While Musa was responsible for significant military, economic, and intellectual expansion, which established Mali as a global power and intellectual capital on the world scene, he is most known for his extravagant gold expenditures during his Hajj, which were so high that they caused economic inflation in the Mediterranean, and particularly Egypt, for many years to come.

Honorable Mentions:

Bill Gates – Mr. Gates barely missed making the top 10, with a peak, inflation-adjusted net wealth of roughly $136 billion. In 1998, Gates amassed the largest nominal sum, ever, of $101 billion. Gates’ net wealth in 2011 was estimated at $56 billion, and he donates the majority of his money to charity.

The Rothschild family – If there were an award for “Richest Family of All-Time,” it would definitely go to the Rothschilds. The European banking dynasty’s combined peak wealth during the mid-19th century is estimated to have been anywhere from $350 billion to $1 trillion in today’s dollars.

King Solomon – According to the Bible, King Solomon was the richest man who ever lived, receiving 25 tons of gold per year, in addition to income from trade business and tributes. However, evidence of Solomon’s wealth outside of the Biblical accounts is lacking.
