Below are listed the wealthiest historical figures of ancient period

Marcus Licinius Crassus		115 BC – 53 BC	Crassus was known in Rome as Dives, meaning "The Rich". It is believed that Crassus expanded his personal fortune to 170 million sesterces. This would place Crassus's net worth equal to the total annual budget of the Roman treasury. depending on the estimate of the "adjusted value" of a Roman sesterce, his net worth may also be placed in the range of US$200 million to US$20 billion.
Augustus Caesar		63 BC – 14 AD	Listed by Time Magazine with "$4.6 trillion" because he "personally owned all of Egypt".
Croesus		died 546 BC	The name of Croesus, a historical king of Lydia, was proverbial for wealth already in antiquity; this is probably due to his being the first ruler to issue true gold coins with a standardised purity for general circulation and not necessarily for his personal wealth.
