Vladimir Putin’s wealth, even by the most generous of calculations, pales in comparison. In fact, throw in the vast riches of Microsoft MSFT, -1.24% co-founder Bill Gates, Warren Buffett of Berkshire Hathaway BRK.A, +0.36% fame and Amazon’s AMZN, -1.78% Jeff Bezos, and their combined fortune doesn’t even approach the riches of history’s wealthiest figures.

Take Augustus Caesar, for example. The first Roman emperor tops the list, according to the Visual Capitalist blog. The adopted son of Julius Caesar controlled much of the world’s most powerful states — including Egypt — as part of his estimated $4.6 trillion net worth. Egypt made up at least 25% of global GDP at the time.
