List of wealthiest historical figures
Encyclopedia
The list of the wealthiest historical figures is an attempt to gather and compare the net worths and fortunes of historical figures against one another. Inflation and other factors devalue currency over time and economies of different regions and time periods valued goods and other commodities at different prices, making it difficult to accurately compare fortunes from different decades, centuries and especially millennia. Also, because several individuals and families never had their financial records revealed publicly, nor had any contemporary estimates of their worth, several persons may be noticeably missing from the list due to a lack of written accounts of their wealth. Some of the wealth estimated includes stock in companies, the value of which is always changing.

This list includes both nominal and real wealth. The nominal value of a person's net worth reflects the price in that person's time, without adjustments for inflation or other factors. The real value of a person's net worth reflects an attempt to adjust a fortune's worth against economic factors that usually devalue a currency, and thus reflect the buying power of that wealth as a stable figure comparable across historical periods.

Historical figures and their wealth

Historical figures often attested to be of great riches, presented in alphabetical order.

Alan Rufus

A companion of William the Conqueror during the Norman invasion of Britain, Alan Rufus, who is also known as Alain le Roux or Alan the Red, received some 250000 acres (1,011.7 km²) in land grants as a reward for his allegiance. His property stretched throughout Yorkshire, Norfolk, Suffolk, Cambridgeshire, Northamptonshire and London, totaling some £11,000 by the time of his death in 1093. This would make Alan Rufus the wealthiest Briton in all the history of the British Isles. His fortune was estimated to be equivalent to £81.33 billion, or roughly US$162.74 billion, in 2007.

s. In such a position, Crassus was able to rebuild his family fortune by seizing the property of executed criminals for himself, and there is evidence that shows Crassus sometimes executed innocent individuals simply to obtain their vast estates and wealth.

Crassus also expanded his wealth by trading in slaves and by purchasing whole neighborhoods of Rome as they burned, for drastically less than market value. At the time, Rome had no formal way of battling fires and they usually were left to burn themselves out, which meant several estates and fortunes were lost in the process. Crassus employed a firefighting brigade of some five hundred men and, after he negotiated the purchase of the burning building and the surrounding estates in danger, the brigade would collapse the home that was ablaze to extinguish the fire before it could spread.

He has been considered the wealthiest man in history, though this claim has been disputed.

Legendary wealth

As records are lost and fortunes often never fully tallied, sometimes only vague stories and grandiose legends are left as witnesses to the treasures held by individuals past. These tales are often believed to be fanciful or exaggerated, and some have even been discredited with new discoveries and evidence. Nevertheless, the fortunes were surely impressive to have remained in the popular conscious through the ages, even if only as legend.

 was more romantic legend than fact. The misconception of his wealth centred around the Mausoleum of Halicarnassus, a great tomb constructed by the king for himself and his wife that was considered a “Wonder of the World” by Greek historians and writers. It survived into the fifteenth century until it was finally destroyed by earthquakes. Afterward, the carved stones and sculptures strewn across the landscape caused writers of the Renaissance to tell tales of the wealth of a king who could afford such beautiful artistry in such great numbers. Much of the remains of the tomb were either plundered for their sculpture or used as an artificial quarry from which castles and fortifications were built over the succeeding centuries.

Yet, discoveries during excavations of the region show that the tomb's construction either directly bankrupted the treasury, or indirectly led to the downfall of the kingdom, as high taxation and strain on resources led to political instability, which eventually emboldened neighboring states to invade the weakened kingdom. Many of the artisans and craftsman that were initially hired to construct the tomb continued to work without pay after the kingdom had been bankrupted, working solely for the glory and renown of their efforts.
